New Chapter - Project GT

From bone stock AP1 to SCCA National Championship winning BSP car...that has been the story of Bumblestook to date since the day I got her almost seven and half years ago. It's been an incredible adventure. In between, she was built to compete in STR, rebuilt and reimaged as a track car where we enjoyed many track days screaming at 9000+ rpm back when she still had an F20C under the hood. She then underwent no fewer than three revisions of BSP builds in the past 4 years pursuing the goal of taking the top spot in BSP. So what's next? Where do we go from here? Do we continue to pour tons of time and money and go wild in Super Street Mod? What's left?

Starting Project GT - 12-5-2017

Well one thing's for sure, she's not getting sold. I've decided to retire her from nationally competitive autocross but her story is not done. The reason is simple. While it's been an incredible learning opportunity the past few years pursuing a dream and she's a dream to drive every second she's on course, it requires an immense amount of work to maintain a top tier nationally competitive Street Prepared car. Triple that effort when you live in NYC and can't just walk out into your garage to work on her or go to events. I've lost track of the number of times I've day dreamed while towing her to events about how nice it would be to be able to just back her off the trailer and drive around and enjoy her more than just a few times a year.

Parts starting to flood in - 12-5-2017

That day dreaming stops now. I've got a really fun build sheet and without class restrictions, I can finally do whatever I want. I won't divulge the details just yet but I'm calling this "Project GT" for Gran Tourismo. She's not going back to stock but she is going to be made street legal once again, retaining much of her performance but being softened just enough so I enjoy her more. Finally she's going to get that full respray to bring her back to her full glory. Something a championship winning car deserves. She'll probably still come out once in a while to play at local events and some time in the future we may return to do some track days but she will cease to become a trailer queen and I refuse to just put a cover on and keep her stored away and not driven like S2000s were meant to be driven.

Pre-Winter Prep

It's been 4 weeks since Bumblestook's final event of the season. At the end of that event I noticed I was leaking brake fluid out of the stainless braided brake line on the driver side front. My initial inspection at the time indicated it might be a crack somewhere in the line but I really just wanted to go home so I didn't jack the car up and pull the wheel off to take a closer look Just to be safe, I ordered brand new lines all around and went to SJF Performance today to give the car a good look before packing her away for the winter.

Faulty brake line - 10/15/2017

It turns out the line itself wasn't bad at all and the nut simply vibrated loose (ah the joys of Street Prepared). We opted to just tighten the nut for now and not replace all the brake lines as there didn't seem to be a good reason to do this right now. I'll just have to add this to the list of things we check periodically. For my own reference though, these are the parts and part numbers for the new brake lines.

Wilwood 220-10841 brake lines for the front calipers

Techna-Fit Honda S2000 Rear Brake Lines - HN-20000R

The usual ATE DOT4 Brake fluid

With the brakes sorted, the only thing left was to drain out the remaining E85 in the car which turned out to be around 3 gallons. I left enough fuel in to drive Bumblestook back onto the trailer and filled her up with pump 93 on the way back to storage. Lastly, mostly because I don't have a lot of space, I decided to mount the Hoosiers TomO won at Nationals for Bumblestook on my other set of CCWs.

Fresh tires mounted for next year

She's now tucked away for the winter. I'm not really clear when I'll run her next year but she'll likely be on a reduced racing schedule as I focus on improving my driving and running Lupa, my STR S2000 more instead.

All ready to be put into hibernation - 10/15/2017

FTD and Top PAX - The Beehive 2017

I started this tradition in 2013 where I'd run Bumblestook with 4 drivers (myself included) on her final event of the season for what's basically a fun event with friends. This year was no different and with a tank full of ethanol from Nationals, I wanted to burn it all off in the most fun way possible. This year, the "beehive" as I call it would consist of James, Rad, Hez and myself. We got really lucky today with awesome weather and a course that seemed almost designed for the car. Every corner flowed nicely and was smack in the middle of Bumblestook's power band. To top it off we got 7 runs each for a total of 28 runs. We burned through most of the fuel, got rid of all the OPR from Lincoln and went through 8 gallons of water trying to keep the tires cool.

James getting ready to run - NNJR SCCA - 9/16/2017

This was the first time James was going to drive Bumblestook and although initially intimidated he soon got comfortable and put in some awesome runs good enough for 2nd RAW and 2nd PAX overall. Rad was a dirty boy. He only had one clean run (his first). He's always driven very close to cones to cut distance in his STR S2000 which is normally a good thing but unfortunately, Bumblestook's wider body was giving him trouble. He was just a bit too close.

Hez getting ready to run - NNJR SCCA - 9/16/2017

For Hez though, this was like putting on an old glove and he was fast right out of the gate. He easily took top PAX and FTD after a few runs and only extended the lead with each run. I was a bit inconsistent today but somehow pulled a not-so-crappy run to end up with 3rd RAW time and got bumped out of 3rd in PAX by Evan in the SSR Z06 on his last run so ended up 4th in PAX overall. I'd say finishing off the season with Bumblestook taking top 3 fastest times and 3 of the top 5 PAX times out of 126 drivers isn't too bad. Of course we got a bit of help with none of the SM or SSM cars showed up today. Today was more about sharing the joy of driving Bumblestook and having fun with friends and we all had boat loads of fun.

The Beehive 2017 - NNJR SCCA - 9/16/2017

She wouldn't be a Street Prepared car without some kind of failure this year though. As I was loading her on the trailer we noticed it was leaking some fluid. When the car is running there seems to be a bit of fluid coming out from the front driver side stainless braided brake lines. I've had that line there since Bumblestook was a track car so maybe it just failed. The odd thing is that it's not leaking when the car isn't running and didn't leak when I got to my storage and drove it off the trailer. The brakes are still fully functioning. I guess we'll have to take a close look at this in the off-season and probably pre-emptively replace all the lines just in case. This is a safety issue and I don't take chances with safety. I'm just glad it didn't happen at Nationals. I guess this is Bumblestook's way of telling me she's ready for winter hibernation.

Finishing Unfinished Business

Before I start, I want to thank and congratulate Tom O'Gorman for putting in spectacular drives in Bumblestook to take the 2017 SCCA Solo National Championship in BSP. Not only did he take the win in BSP, but the resulting time was good for top PAX  for the Thursday/Friday run groups and 2nd overall PAX (by only 0.05 seconds to Billy Davis in CSP) out of over 1300 drivers. It took 5 years of development and an alien driver but I finally reached my personal goal to put Bumblestook on the top step of the podium for BSP.

SCCA Solo National Championships 2017 - 9-5-2017

Looking at a slice of time and a victory is insufficient to see how much work it took to get here and I couldn't have done it without all the incredible people that worked with me throughout the years. I wanted this build and setup to be done on my terms based on my own experimentation and learning along the way even if it took me longer to get there. There was nothing cookie cutter about it and I am grateful to have worked with people who let me try things even when I frequently went off the beaten path in pursuit of knowledge. This victory is validation that the time and effort you all put in was worth it and what we created is truly a case where the sum is much greater than its parts.

I want to thank Jeff DeVos (retired S2K specialist) who did a lot of the early wrenching on the car and putting up with so many iterations of my build. Jeff Evans from Evans Tuning for all his fabrication and tuning skills to get the ITBs to work and give me the most usable and reliable power band we could extract from the F22C within the absolute limits of the rules. If anyone knows how to extract the most power from a Honda, Evans is definitely your man. Evans Tuning was her 2nd home during her early years of development. Steve Farkas from SJF Performance would be her 2nd home in the later years. Not only did he help me fix the remaining reliability issues with the car, continue to maintain her and perform countless alignments to perfection as I fine tuned her setup, he's been a great friend who's gone through extra lengths to make time for me anytime I've needed it. Brian Karwan from Karcepts for putting my diffs together that haven't failed despite insane 8800rpm prosolo launches and his incredible sway bars that were crucial to getting the perfect balance for the car this year. Anze suspension for rebuilding my old school Moton tripples and working with me to get the valving dialed in. There's always room for improvement but I think her pace is very close to target. Joefis racing for the spoiler work. Hoosier Racing Tire for making the most awesome DOT R-Compound racing tires ever made. I also want to thank Hezron Laluces for being a great friend and amazing codriver in 2015-2016. He's a natural, fast and consistent and his driving skills helped me focus on car setup while he continued to demonstrate our increased pace as development progressed. Finally, I want to thank my wife for understanding how important racing is to my life and continuing to support my efforts.

Tom's Championship Winning East Course Run - 9/7/2017

Tom's Championship Winning West Course Run - 9/8/2017

The Back Story

I went to my first SCCA National Championship in 2012 codriving Jon Caserta and Tory Benya's STR S2000. Bumblestook was a track car at the time and obviously not competitive in any class so I flew out and drove their car to see what this was all about. While walking around paddock I came across Jason Uyeda's BSP S2000. He would eventually win BSP that year and make cover of Sportscar magazine shortly after. I looked into BSP more and realized it was the perfect class for an S2000 enthusiast. You could run super sticky race rubber and combine all the best parts of every S2000 to make the "perfect S2000" and I got inspired. 

Jason Uyeda's BSP S2000 - Sept 2012

I came home and the first thing I did was remove the wing from my car and created a Facebook album called AP1.2.CR BSP Build with the description "It's going to be a freaking awesome AP1/AP2/CR hybrid". My goal was to take the strengths of each generation S2000 and combine them into one car. Of course the challenge here is that I really didn't really know much about suspension tuning. I had been autocrossing on and off for 7 years at that point but up until then I wasn't exactly the first person you'd talk to about setting up a fast autocross car, let alone a nationally competitive one. I knew it would be a steep learning curve and there weren't much (if any) resources at the time on how to set up a BSP S2000 so I'd have to learn and figure it out on own along the way. This blog already has all the details of the build so I won't go into it that here but 2013 would be he first year of development of Bumblestook in BSP trim. 

I granaded my diff in 2013 just before the NJ ProSolo and replaced it with the ATS Spec III diff that Karcepts was able to quickly get for me. I went to nationals that year with Bumblestook for the first time with Dan Stainback as my codriver and he was able to get into the trophies but it was clear that trying to keep Bumblestook as both an autocross and track car wasn't going to work. Robert Thorne won in his S2000 CR (a.k.a TheBigBadWolf) in BSP and Bumblestook was way off pace. 

In 2014, I fully committed to making Bumblestook a nationally competitive autocross car. She spent the winter at Evans Tuning as we prepped her to the limits of the rules and tried to extract as much power as we could with an ITB setup. Despite a lack of testing, I won my first ProSolo that year in DC. I continued to power through that year not winning anything else and went into Nationals only to finally accept that the AP2 transmission gearing wasn't going to work. Chris Mayfield won BSP that year in Thorne's S2000 and the Mazdaspeed Miatas were starting to get better prepped and the once overdog S2000 only had a 0.3s lead over the MSMs. We needed more top speed to handle a nationals style course and I had ideas on how to make her faster the following year including swapping in an AP1 transmissions for taller gearing. However, two years of basically non-stop working on prepping the car and throwing all my resources at it had taken its toll and I was on the border of quitting racing altogether.

After taking a winter off from any car related activities, I realized how much I really enjoyed and missed racing and I was motivated to try again in 2015 and made more changes to the car. Thorne's CR had left BSP and moved onto SSM and from the looks of things, Bumblestook would be the only S2000 to try and defend the title. I picked up Hez as my codriver mid-season. Once he figured out the car, he was instantly fast and we went to Nationals (his first). We got destroyed by the MSMs that year with Steve Oblenes winning BSP in Anthony Porta's MSM. Hez was just out of trophies but personally I felt I had dropped the ball and failed to continue in the line of S2000s that had successfully won the class. 

In 2016, determined to retake the win in BSP for the S2000, Hez and I did a full season of codriving. I made further improvements and setup changes and Hez was killing it at our local events frequently taking FTD and top PAX and securing the NNJR SCCA driver of the year. We finished 1-2 at both Toledo and DC ProSolos and were coming into Nationals feeling good. Unfortunately, we snapped the axle at the ProSolo finale and the 14 year old steering rack bushings were shot. Bumblestook's normal steering responsiveness wasn't there. Anthony Porta took a decisive win in BSP in his MSM. Hez was able to get Bumblestook into trophies but the MSMs had gotten even faster. They were a solid 2 seconds faster than the rest of the class. It was game over. The MSM was now clearly the top dog in BSP. Disappointed in the loss, I knew I had to at least try one more time. I had unfinished business and I couldn't walk away without feeling like I did absolutely everything I could. 

For 2017, gloves had to come off. I made the final changes to the car to try and find as much as pace as I could. The car was checked and double checked. Anything that might have a chance of failing or aging, was replaced. The mild winter had allowed us to make lots of progress and the car was ready for testing as early as the end of January. Unfortunately, this year had other plans for me. Various issues had caused me to miss all our early season events and Bumblestook didn't get to see daylight until the end of May where I was only marginally able to scrub off OPR from the previous year. We went to Toledo for the ProSolo. That was only the 2nd event in the car for 2017. She was undrivable and horribly pushy and I had to make some quick changes to try and figure out her new concrete setup. Thankfully I was able to squeeze out the lead and take the win..only my 2nd ProSolo win in the car. I changed the header and visited Evans Tuning to retune to try and get more midrange torque but it wasn't until July before I was able to take her out again bringing on Dave Corsaro to drive with me to help provide some feedback on car setup. Unfortunately, my bad luck would continue and rain would prevent us from getting any useful testing. We had one dry run which was good enough to determine a front bar adjustment was needed. Finally a few weeks ago, we got our first (and only) real dry weather test. I think I had figured out a new setup (at least on paper) and put Hez back in the car as a proper reference and I knew then I had figured it out and the car was properly fast. 

Despite all this, I knew that we were still going to be underdogs. The MSM was still the faster car. They're lighter, make as much power and more torque than an S2000 in BSP trim and I suspect are easier to drive at the limit. If I wanted to get Bumblestook to the top of the podium I'd need to put in a proven fast driver in my car on top of making sure the car had optimal pace. I had reached out to Tom O'Gorman a few months earlier presenting him with the challenge/opportunity to try and dethrone the MSMs in the most prepped BSP S2000 in the country. Things eventually worked out and the codrive was secured and I had to focus on making sure Bumblestook wouldn't fail him. 

He took a run on the test course for the first time and mentioned that she was a tiny bit too loose going through sweepers. I lowered the rear pressure a bit and sent him back out for a second run. At this point, Bumblestook was feeling on point and on his third run he put down a scorcher run of a 33.0s on the test course, a raw time that was already faster than many of the cars on the course that should be faster. I ran the car again in the afternoon only enough to scrub in the fresh competition tires and shut her down. All the testing was complete. It made no sense to risk the car any further until competition days so I cancelled the rest of my planned testing for the following day. 

Day 1 of competition was a nail biter. Tom had secured a lead by the 2nd run but on his final run, Chris Edens had crossed the line to take the lead. A few seconds later, Tom crossed the line and narrowly took the lead back by 0.024 seconds. Tom told me later that that run should've been faster but he made a small bobble in the final run up to the finish. I checked the data. Sure enough, his pace was 0.7 seconds faster up until that bobble (going into the final chicane). Bumblestook was a bit too loose for this course and had I known earlier, I might have tried to soften up the rear bar a bit  to bring some of that stability back. 

Day 2 we were on the west course (corn side) which had lower average speed than the east course. Bumblestook's balance here was much better and Tom put in an early lead and backed it up with an even faster 2nd run. On his last run, Chris Edens in his MSM would get close to Tom's 2nd run time but at this point Tom had already won. Tom was on course and didn't know this so he was still going at full speed and finished an incredible run to take the win by 0.66 seconds. He ended up top PAX for the Thu/Fri run groups and just 0.05 seconds shy of top PAX overall out of 1300+ drivers (which he clearly had the pace for if it wasn't for the day 1 bobble).

Overall I'm ecstatic that we finally completed the unfinished business and took the BSP win back to the Honda S2000. Realistically and based on Tom's feedback I suspect that the MSM is still the overdog in the class and while I provided Tom with the best S2000 we could get him in the form of Bumblestook, his raw driving talent is what gave the ultimate edge to secure the win. Yes, there's probably some additional suspension tuning to make her easier to drive and possibly marginally faster but that's probably true for all cars. I don't know where I'm going from here in 2018 but I feel like a big monkey is finally off my back and I'm super happy for Tom's win (his 3rd national championship in 3 different classes) and I'm extremely proud of Bumblestook. On her final test, with all eyes on her on the center stage, she stayed together and gave everything to let Tom get the job done.

Bumblestook is my race car. 

There is nothing like it and this one is mine. 

My race car is my best friend. It is my life. 

I must master my race car as I must master my life. 

My race car, without me, is useless. 

Without my race car, I am useless. 

I must drive my race car hard.

I must negotiate corners faster than my competition trying to beat me. 

I must reach the finish before they finish. I will!

Pre-check before Nationals

Yesterday I took Bumblestook to SJF Performance to double check the alignment and nut and bolt the car in preparation for Nationals. The rear toe slipped a bit since the last event and the front subframe bolts had loosened slightly so the alignment was reset and all the bolts double checked. We also raised the rear bar from full soft to 5/7, my baseline concrete setup.

Bumblestook ready for Nationals - SJF Performance - 8-26-2017

The trailer has been at SJF this week to replace the old / cracked breakaway box from the trailer with a brand new Tekonsha unit and also solder and heatshrink wrap the remaining wires that were still using taps. I've been getting brake controller shorts for that past year intermittently and these were obvious potential sources. In the end though it wasn't any of this that caused the problem. Turns out one of the brake wires going through the axle shaft was frayed. Luckily it was easily visible when you pulled the wire so I wrapped it with electrical tape for now and that seems to have cured the problem.

New Tekonsha Breakaway System - 8-26-2017

Final Testing before Nationals

We got the most perfect weather and course to finally do a true dry/hot weather test of Bumblestook in her natural element. It was time for the bumblejockey, Hez, to get back in the codriver spot. There really isn't any other driver (besides myself of course) that has had as much seat time in Bumblestook as Hez has and putting him in the car would give me the best measure of her relative pace from last year.

Waiting patiently to be let loose - NNJR SCCA
Meadowlands, NJ - 8-19-2017

We softened the front sway bar one notch based on the feedback from Dave at the last event. We set our usual pressures and as soon as I took my first run I knew she was back. Even on cold tires, her balance was perfect. It did all the quick transitioning S2000s are known for with none of the bad behavior. The rear would slide out a little then catch, the front would turn in super quick and go wherever you wanted with even the slightest change of steering angle. She felt the best she's felt ever and the results showed it.

Top PAX results - NNJR SCCA - 8-19-17

After getting the tire temps settled, Hez put in a blazing fast run to sit in 2nd in PAX, only 0.015 seconds behind GJ in Lipman's very well prepped and tested SSR GT3 and I ended up 6th out of 134 drivers.

RAW time results - NNJR SCCA - 8-19-2017

The RAW times were there as well. Hez's fast run was only a tenth of a second away from the SM/SSM times of Dan Stainback's STI and Jake Namer's RX7. This is pretty astonishing considering that today's course was in many ways a power course with nice sweepers and flowing transitions. The most interesting thing is if you watch our video, you can see we're still leaving a bunch of space to the cones which means she had a lot more pace out there. This was only her 4th event this year and boy is she showing she's eager to go back to Lincoln and take another shot at the championship.

NNJR SCCA/PCA Joint Event - Meadowlands, NJ 8-19-2017

Oh and for those curious, the new yellow bikini top to keep the interior cool when the hardtop is off is a made to order piece from Covercraft. It's a Covercraft Weathershield HP Convertible interior cover, model number IC3040PY (The last letter is the color I think so if you want another color, just look for the IC3040). It's really designed for the S2000 CR which has no soft top but obviously would still fit all S2000s although I'm not sure why you'd buy one if you already have a soft top that goes up in 10 seconds.

Testing with Dave at NNJR SCCA

Nationals is only 6 weeks from now and this is the first time this season I've been able to take Bumblestook out for some home region testing with the NNJR SCCA at the Meadowlands. I asked Dave Corsaro  to codrive with me for this event so he could help me quickly dial the car in. Although we had the threat of rain, first heat ran mostly without a hitch in the dry but then the skies suddenly opened up just before our heat.

NNJR SCCA - Meadowlands, NJ - 7-23-2017

Our first two runs were done completely in the wet and it was a pure exercise of car control as Bumblestook wanted to drift more than she wanted to go straight. The course started drying up by my third run but just as Dave was about to go for his first dry-ish lap, the skies opened up again, wetting the dried parts of the course once more. Thankfully though we got a break and it finally did stop raining and a combination of winds and hot conditions allowed us to take our final 2 runs in the dry. 

Dave about to go out for his first lap in wet conditions- 7-23-2017

Dave identified a slight push in the car in our 5th runs and wanted some more front bite so we took out some front compression. I took my final run and the car felt much better. I dropped a good chunk of time and the course was now completely dry (well at least the racing line was). Dave finally got to drive Bumblestook at full speed for the first time and set a good raw time but nicked a cone in the slalom. Unfortunately that was the extent of our testing. The pace was definitely there to compete for the top spots but we ran out of runs. I may try to raise the rear bar a bit at the next event to get just slightly more rotation. It's tricky to tell based on today's data as the conditions were constantly changing. Overall though, I think it was a successful day. Her power delivery with the new tune was smooth, the new alignment seems to be balancing the car well and the handling is ballpark where we need it to be so it's just minor adjustments from here on out. 

NNJR SCCA - 7-23-2017

Extracting Power

Bumblestook was already making good power but it was more towards the top end. In autocross you spend a lot more time in the midrange so the focus has always been to make a fatter, more usable torque curve from around 4000-7000rpm which is why I decided to swap from the PLM header to the Toda Torquie-Kun. In order to make sure Bumblestook would run optimally, I didn't want to take her out without first getting her on the dyno for a retune so I took her over to Evans Tuning today so Jeff could make sure she was running right.

Jeff Evans tuning Bumblestook - Evans Tuning - 7/15/2017

The tank was still full of E85 from Toledo which was ideal. We did a baseline run without making any changes to the old tune and it showed a massive 20+ ft-lb torque drop midrange. This would've been very noticeable (big time bog) if I had tried to run her without retuning. Turns out the VTEC crossover was too low for the way the Toda header flowed so he raised it a little and after a several pulls and adjustments to the fuel map Jeff was able to extract about 10 more ft-lbs of torque and 10-hp in the midrange over the old tune/setup.

Dyno Tune - Evans Tuning - 7/15/2017

It's important to note that comparing dynos over different days and conditions even of the same car isn't really worth doing so the increase is a data point but take it with a grain of salt. I think the important thing to note is that the power did indeed shift more towards the midrange (there's actually a noticeable bump in the graph that wasn't there in the old tune) at the cost of a slight loss of power at the top end. I think that's more than a fair trade off. I will note however that the previous tune was done during the winter and we're retuning in the middle of the summer so in theory the old tune should've produced better numbers to begin with so the fact that we're seeing gains while tuning at much warmer and humid conditions is very promising. We'll be testing her out next Sunday to see how all the changes work out.

Mounting fresh tires - SJF performance - 7/15/2017

I also stopped by SJF Performance so Steve could finally mount the fresh set of tires we'll be using for Nationals on my 2nd set of CCWs. Hopefully I'll be able to scrub these in some time in August before we head out for Lincoln.

Toda Power and Licking Wounds

The Toledo ProSolo is always rough on cars. Combine incredible grip with intense heat and you've got yourself a potential recipe for disaster but thankfully Bumblestook held together to take the win last week. However it was not without issue. I had trailer wiring issues and had no trailer brakes most of the way there and back and Bumblestook's handling felt a bit inconsistent so it was time to get her back on the lift to give her a good post big event maintenance at SJF Performance.

Toda header installed - SJF Performance - 6/20/2017

First though, her win gave Bumblestook dibs on the new Jet Hot ceramic coated Toda Torquie-Kun Header. While I purchased this header for Lupa, it made more sense to put her in Bumblestook where I can hopefully use it to get even more usable midrange torque as well as keep the engine bay a bit cooler.

New header gaskets - SJF Performance - 6/20/2017

New header gaskets - SJF Performance - 6/20/2017

Installation was pretty smooth. The runners go out a bit further than the PLM header so we had to insert the header from the engine bay but fitment was excellent. Of course, new gaskets were put in for a proper seal.

Toda header installed - SJF Performance - 6/20/2017

SJF then flushed the diff fluid. The Toledo ProSolo was only the second event on the new ATS Spec III Type DD diff so it's just basically broken in but the diff fluid coming out was extra dirty. Hopefully it's just break-in carbon from the clutch plates but the diff itself seems to be having well and I'm not hearing of feeling anything unusual so I'm not too concerned. Once all that was sorted, she was put onto the alignment rack. The alignment had definitely shifted quite a bit and after talking to SJF, we decided to try a pretty different and perhaps more aggressive alignment this time around just to see how it would change things. We went with much more camber up front and a hair of toe out for slightly faster turn in. In the rear, we reduced the camber a smidge but still kept the 1/16" total toe in for stability.

Got Camber?  - SJF Performance - 6/20/2017

The new alignments specs are:

Front:
-3.7 camber
5.4 caster
0.04in total toe out

Rear:
-2.3 camber
0.06in total toe in

When we went to reset my sway bars back to meadowlands settings SJF noticed that the nut on my front sway bar was missing. The bar was definitely connected on Saturday in Toledo so somehow between Saturday and Sunday of the event the nut vibrated loose. The funny thing is I was struggling with understeer up until then so it's almost like Bumblestook just fixed herself for me by disconnecting her own sway bar haha. We reconnected it and dialed the front bar down from 5/6 to 3/6 and set the rear bar back to full soft from 5/7.

Added exhaust hanger - SJF Performance - 6/20/2017

I'm not sure if it's the new header or the fact that some stuff shifted but the exhaust tip was touching the rear bumper. To move it back into position, SJF welded an additional hanger onto the exhaust to pull it back towards the driver side so now there's no more play left and right. That was it for all the Bumblestook upgrades and fixes. The final thing to fix was the wiring/overload issues with the trailer. I suspected the issue was related to the trailer connector so that was replaced with a beefier heavy duty one and so far the trailer seems to be operating correctly again.

We don't have any events until the end of July so Bumblestook will be off to Evans Tuning next month to get a quick retune for the new header to make sure she's 100% when we go to Nationals.

BSP Win at Toledo ProSolo 2017

With only one day of testing this season, it was time for Bumblestook to go to her first big event this year, the Toledo ProSolo. The Poconos event a few week ago was a good test to make sure she was generally working well but I didn't really get a chance to do any suspension tuning so it was unclear how she'd behave on the high grip concrete at Toledo. Before leaving, I swung by SJF Performance to drain out all the pump gas so I could switch to E85.

Some last minute work at SJF Performance - 6/8/2017

My plan was to just run pump gas in Toledo since I didn't have time to get any C85 (my preferred E85 blend) but thankfully Billy told me about a Speedway in Waterville, OH just 15 minutes from the hotel that had E85 at the pump. Unfortunately with pump E85 the ethanol content can vary from 70% all the way to 90% but having a Flex Fuel sensor on the car, the tune can compensate for any amount of ethanol so I took the chance. Turns out this particular station had the same ethanol percentage as C85 and she seemed to run ok so I was happy with that.

Filling up on corn juice - Watterville, OH - 6/8/2017

The next day I arrived on site early to get a good spot in paddock and it started pouring. This is pretty typical of Toledo but I'd rather it rain all day on a Friday than during the competition days in the weekend. Since I had no baseline to go against I just did what I always do when I get on concrete which is to up the rear swaybar setting going from full soft to 5/7 on the new Karcepts rear bar.  I used to go full stiff with the Ankeny rear bar but the Karcepts bar can go stiffer than the Ankeny bar so I didn't want to max it out just yet. It eventually stopped raining and we got to do practice starts in the dry which she was able to get done with no problems. Unfortunately Kirk's BSP 240Z destroyed a drive shaft u-joint and sheered the transmission output shaft during their practice starts so to keep class numbers, I took on Kirk as a codriver and Lee took on Mike.

Arrived on site - Toledo ProSolo - 6/9/2017

Saturday morning rolled in and it was time for the first set of competition runs. It did not go well. She was extremely pushy everywhere. It didn't matter if it was under braking, under power or just transitioning. Bumblestook did not drive like an S2000 and I was a bit worried. I needed to make some big shock changes to get her front end to bite better. The Moton tripples have 5 settings for low speed compression and it was set to full stiff in the front. I decided to dial it back 2 clicks and that transformed her completely for the afternoon runs. She started to drive as expected and I was able to regain confidence to push her a bit harder. She was rotating nicely under power with just enough slip angle to slide the rear around but it would still set and the diff could put the power down as needed.

Ready for morning runs - Toledo ProSolo - 6/10/2017

Unfortunately I was still having difficulty getting my timing right and was hitting cones in most of my runs so I found myself at the end of day 1 in 2nd sitting 0.7 seconds back from Lee. I reviewed the video and data of the runs overnight and knew that if I could just stay off the cones I could pick up some time in other sections now that I was more willing to chuck her into a corner and let her stick. I also felt that the front didn't have enough rebound so I added a click of rebound to control the front a bit more.

In grid for day 2 - Toledo ProSolo - 6/11/2017

I needed a good left side run and thankfully being 2nd I was starting off day 2 on the right so I took the first run as a recon run and get the tires and brakes heated up. When I got to the left side I was able to finally get in a clean run by being a bit safe and taking slightly wider lines and still finding 0.8 seconds to take the lead by about 0.1. I went back to the right side and put in a much faster run now that I was in the lead and tried to find her limits more. I was able to find another 0.7 seconds but coned the slalom so no improvement there. Back to my final run on the left, I pushed a little harder but the tires were starting to feel a little greasy and she was sliding a little more. I still managed to find some more time and seal the win with a 0.3 second lead.

I definitely lost some time in the launches. There was so much grip with the concrete and Hoosiers that even launching at 8800rpm I was bogging hard. Not having torque was not helping me here. I think she definitely had a lot more pace out there. I need to work on finding out how much space I need to give to clear the cones especially on right hand turns. The cone troubles are going to bite me hard at nationals if I don't figure it out. The Toda Racing Torquie-Kun header that I had ceramic coated for Lupa will have to be given up to Bumblestook I think as she has a greater need for a better mid-range torque curve so I'll have to find time to get her back on the Dyno. That will probably be the final change for the season.

Toledo ProSolo 2017 - 6/11/2017

I'm really happy with the changes for this year and it was great that I now have a working concrete setup for her. She didn't break and helped me secure the win defending her win at Toledo from last year. Going racing on my birthday was a treat. Winning was icing on the cake. We've got a little more work to do but good job Bumblestook!

SoS Hood Dampers

No big update today other than finally installing the Science of Speed hood dampers that I got over the winter but have been too lazy to install. These are replacing my rusting PasswordJDM ones that don't open nearly as much

Science of Speed Hood Dampers - 6/3/2017

Less than a week before we head out to Toledo. I've decided we're not going to run her at the NNJR event tomorrow for testing since I don't want to risk having any issues this soon to a big event.

All Systems Are Go

After months of various unrelated issues coming up that have prevented me from bringing Bumblestook out, the stars finally aligned and today I was able to take her out on her 2017 debut after all the work done over the winter.

NEPA SCCA Autocross - Poconos Raceway - 5/27/2017

With only two weeks left before we head out to Toledo, time was quickly running out to get her tested. The summary of changes over the winter are:

• Went to 315/30/18 Hoosiers up front to make it 315 all around (Previously I was running 295/315 staggered)
• The tires on the front now were my rear tires from Nationals last year so they were covered in OPR from Lincoln
• Switched from 10mm to 15mm spacers up front for clearance
• Cut more of the front fender out for clearance and added overfenders
• Switched to Karcepts front and rear sway bars for increased adjustability
• New ATS Spec III Type DD diff was installed
• Replaced passenger side front knuckle, wheel bearings and studs
• Replaced passenger side axle with the matching spare we used to replace the driver side axle during the ProSolo Finale
• Added mount for tablet so I can run SoloStorm this year for datalogging

I wanted to test for clearance, scrub the OPR off and break in the new diff as well as get a general feel for the balance of the car with the new setup. NEPA hosted an autocross today at Poconos Raceway. These are typically very fast courses but for some reason, today's course was particularly tight and slow. When we walked the course, many of us thought it was going to be a disaster. The gates were very tight and the elements felt all over the place and visually confusing. I was personally surprised that it drove better than I expected and all the transitions helped me achieve my goal of getting a baseline balance with her new setup.

The new tablet mount worked perfectly for capturing data

My first 3 runs were spent scrubbing off OPR. The fronts weren't hooking up too well with all that clag on the tire so I took the course at about 80% pace and at least get the diff to work. The new ATS diff feels incredible. The engagement is very smooth and I had no problems getting power to the ground. Also this year I'm trying much lower tire pressures so I started the day off with a target 28/25psi. She was feeling a bit pushy so I kept lower the front pressures until they were 25psi even and I really felt she was ready to dance but still leaving a bit of push which I was ok with at the Poconos. If this was at the Meadowlands I would've raised the rear bar to test but I wasn't about to do that on the road course so I'll leave that for next weekend. Also, since I was testing, I took the opportunity to take different S2000 drivers on ride alongs so they could feel what a BSP S2000 really feels like. The reactions were, as expected, priceless. 

Poconos Raceway - 5/27/2017

Unfortunately after our third runs another car had some issues and leaked coolant at the beginning sections of the course so on my final two runs I backed off a bit there to avoid sliding there but I was still able to drop time elsewhere. On my final run, I went solo and put in a good time but the narrow gates and the wider stance put me in cone trouble as all my runs ended up dirty. Overall, I'm super happy with how she performed today. Data showed we pulled a max of 1.6Gs lateral and I didn't even get her to slide yet so there's more. She performed flawlessly, the tires are OPR free and smooth and I had no rubbing anywhere. We've got one more day of testing left before her first big event this year so hopefully I can dial in the suspension a bit more and really make her dance.

Ready for the 2017 Season

Usually Bumblestook hibernates all winter long but the relatively good weather we've been having has allowed us to complete all the modifications and prep work for the 2017 racing season well ahead of schedule. First order of business was to get some fresh fluids in there.

Oil and Transmission fluids changed - 1/29/2017

While working on the car last week we noticed that the exhaust flex bolts had rusted quite a bit so I opted to replace those now since I was ordering some parts from Honda anyway.

Finally, we set the sway bars to the settings I wanted as a starting point for this season (1 hole from full stiff in the front and full soft in the rear). We also did the first alignment for the season. Since I have more tire and slightly wider track up front, I decided to reduce the front camber a bit but leave the rest the same to keep the general balance. There will be undoubtedly many more alignment adjustments throughout the year but I think this is a good starting point.

Front:
-3.4 camber
5.2 caster
0 toe

Rear:
-2.5 camber
0.06 (1/16") total toe in

Ready for alignment - 1/29/2017

Big thanks to SJF Performance for getting all the work done before the early season rush. Bumblestook is ready for the first event in 6 weeks where we'll be able to test all the changes.

New ATS Diff and Replacing a Bad Knuckle

Last year we identified additional items that needed to be replaced over the winter. The ATS diff that I had been running for the past 3 years was still working but the clutch packs were starting to slip. Rather than have it rebuilt, I opted to send Lupa's spare OEM diff housing over to Karcepts and have Brian install the new ATS Spec III Type DD LSD in it. Since we had a break in the weather this weekend, SJF Performance installed the replacement pumpkin as well as replaced the passenger side axle with the matching spare to the driver side axle that broke during Nationals as a precaution. We also noticed that one of my rear diff mounts was installed backwards so we corrected that as well.

When SJF was installing the new camber joints last year, he found that the threads on the passenger side front knuckle were cross threaded from a previous installation. He was able to tap and fix the threads but we weren't super happy leaving it that way. I picked up a used AP1 passenger side knuckle and he replaced the wheel bearing and hub and installed a fresh set of ARP extended studs so I could keep the old knuckle as spare complete unit.

New wheel bearing - 1/21/2017

New OEM hub with ARP extended studs pressed on - 1/21/2017

Spindle, new bearing and hub all pressed together - 1/21/2017

This completes all the major mechanical work that needed to be done over the winter. She only needs an alignment and new fluids before the season starts.
