Final Prep for Nationals 2014

Bumblestook remained parked after coming back from both Wilmington events but it was time to get her out again and make her ready for the big show. I was supposed to get everything done two weeks ago but forgetting both the storage and car keys at home made it impossible to actually get her to the scheduled alignment on time. Steve at SJF Performance was able to carve out some time for me this weekend and he mounted the competition sticker Hoosiers to the other set of wheels and we rechecked the alignment.

Sure enough, all that grip in Ohio caused the little tabs holding the alignment washer in place to bend again and she was showing 0.5" of toe in at the rear when it should be no more than 1/16" total (no wonder I had to crank up the rear bar for the Wilmington Championship Tour). The front alignment remained perfect and didn't need to be touched. Steve reset the rear back to where it should be so hopefully we'll be all set this time around.

We also did a bit more fender massaging since I still managed to catch the driver side fender during the Wilmington Tour. We probably added another 1/8" of clearance so hopefully that's all we need to finally not hit the fender at all. She's all loaded and ready for Nats now.

It's been one crazy year and looking back she's already surpassed my hopes for the season. Hoping for a solid performance at nationals against the other 15 drivers in BSP this year and bring home some hardware.

"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!"

Wilmington Championship Tour

I stayed in Wilmington after the ProSolo because the Championship Tour was the following weekend. I had to take care of one thing before the event. I blew sound at 101.3dB during the ProSolo and while sound rules made it impossible to really get disqualified for sound during a ProSolo, I knew I'd have to come up with a solution if I wanted to not have any issues during the Champ Tour. Bumblestook and the trailer were being stored at Full Throttle Indoor Karting in Cincinnati thanks to Joe O'Gorman who offered up an inexpensive storage solution for those of us wanting to keep our cars in a safe place for the week in between the events. I asked Joe if he knew anyone who could help me weld in a cone silencer into new 3" exhaust tip and I got pointed to Turn in Concepts in Cincinnati. I picked up a Dynatech Vortex 3" cone silencer at Jeg's in Columbus during the week then brought it over to them. They welded it into 3" piping which I planned to then swap into my exhaust if I blew sound again during the Tour.

On Thursday night, my friend Rad flew in as he was going to codrive with me for the weekend. We arrived on site on Friday after picking up Bumblestook from storage. The first thing I did was work on fitting the silencer just to make sure everything fit right and found that while the piping was the right diameter, I had given then incorrect dimensions so the tip was too long and was hitting the axle. I reinstalled the normal turndown and we did a few runs on the TnT course to make sure the car was feeling balanced. She felt a hair pushy at the ProSolo so I cranked up the rear bar to half stiff and felt an immediate improvement on the practice course.

Practice Course - Wilmington, OH - 8/1/2014

After practice, we stopped by a muffler shop in town and had them chop off a good 3 inches from the back of the silenced tip and it finally fit with no clearance issues. It turned out to sound really good but without knowing how much power the silencer would rob, I opted to leave the normal turn down in unless I got tagged for sound again but this time I was going to at the very least angle the turndown away from the mic.

Saturday was day 1 of competition. There was a 50% chance of rain forecasted for Saturday and sure enough an hour before we were about to run while putting the cars in grid, the skies opened up with lightning and thunder everywhere and they had to temporarily halt the event to let the storm go through the area. This worked in our favor because sure enough as soon as the rain clouds moved on, the sun came out and we started to enter drying conditions before our first runs.

BSP Grid - Day 1 - Wilmington Champ Tour - 8/2/2014

Unfortunately, day 1 didn't turn out too well for us. I managed to cone every single run so I was stuck in 4th place, out of trophies, 1.5 seconds off my codriver in 3rd. My head just wasn't in it and I was making plans to skip nationals if we couldn't put in a competitive time on day 2. Day 2 came around and I was mentally much better and more focused. I really didn't have anything to lose and most of my cones from day 1 were due to me hesitating and not trusting Bumblestook completely to stay in it. After second runs I was closing the gap on Rad's combined time but had another coned run. Rad found another 0.1 seconds on his last run but coned it away. On the last run, I went all out and put together a good run. I had managed to get within a couple of tenth's off Mike Lane's time (who went back from a day 1 deficit to win BSP for the event) and we both were able to raw time SSR that day. It also pushed me ahead of Rad, slotting me in for the last podium spot by a scant 0.015 seconds. The course was great, the grip of the lot was fantastic and Bumblestook survived the brutal back to back events on the grippy concrete. With the solid time in the books, Bumblestook made it known that she wanted to go to Nats so we're back on track to go to Lincoln, NE in a few weeks for the Championship. Also, I never went past 96dB during this event without the silencer so I ended up never using the silenced tip anyway.

Wilmington ProSolo

We arrived at Wilmington Thursday night so we could take it easy and not feel rushed like almost every other race weekend. The temperature was a bit on the cool side which was a nice break from the recent heat but we were mostly concerned with the weather forecast for the weekend.

Wilmington, OH - 7/24/2014

We got on site on Friday to register and to get tech inspection out of the way. This time I decided to forego the practice launches as I was already resolved to launching at redline and didn't want the added stress of additional launches potentially breaking anything on the car before the race. We noticed that paddock was a good half mile to grid so rather than waste time walking back and forth, we went to the local Walmart and picked up a cheap BMX bike that was quickly modded to be what we shall now call "Bumblebike". Walking the course, I knew I was up for another uphill battle. The course this time was much more balanced than Toledo but the distance out of the line was longer than usual and I would be at a disadvantage from the launch being the least powerful car of the group. 

Bumblebike - Wilmington, OH - 7/25/2014

Day 1 kicked off and we got our morning runs in the dry. The grip in Wilmington was very comparable to Toledo but more consistent all around. I was happy that we were able to light up the rear tires again at redline and thankfully I think the 10mm spacers worked and no more crumpling of the fenders occurred. There was a chance of rain in the afternoon so I inflated the Hoosier H20s in preparation of having to switch over to rain tires. I didn't expect to go faster on the wets but I've been wanting to do some testing since I've never run Bumblestook on Hoosier wets before.

Hoosier H20 - 245/45/17 - 7/26/2014

Somehow the rain skirted the airfield and we got dry afternoon runs as well. I was able to move up a few spots but was still too far off pace compared to other BSP cars running in SPA. I knew I was leaving a lot of time out there so I had to drive more aggressively and trust the grip level more. Overnight, the forecast was calling for severe thunderstorms. I had fully expected to have to run in a torrential downpour but again, we were saved and not only did we get to run in the dry but the sun even found its way through the clouds.

Getting ready to run Day 2 - 7/27/2014

I found nearly a full second between the left and right courses and was happy with the raw times but I coned away the fast left side run which would've left me in the trophies. Bumblestook's feeling really good right now though and I'm looking forward to the coming weekend for the Wilmington Championship Tour. The only minor issue is that we blew sound this weekend, getting logged as high as 101.3dB going flat out through the slalom so we'll have to find a way to quiet her down a few dB before this weekend so we don't get disqualified. However I think the position of the sound station, the low clouds and the strong winds contributed to this. Still, better to not take any chances.

Wilmington, OH - 7/27/2014

Overall I think it was a successful weekend despite not finishing where we wanted. She's running great and handles exactly the way I want and didn't break anything. Being out of the points running, we're going to skip the ProSolo Finale this year and just go to the National Championship to save her from any further brutal launches until next season.

Wilmington Prep

With back to back races in Wilmington, Ohio coming up, it was time to go over Bumblestook yet again to make sure everything was still ok after surviving the brutal Toledo ProSolo. First up though was having my trailer modified by Steve at SJF Performance so I can carry an extra set of wheels with me. The Touareg is a fine towing vehicle but it's impossible to fit a set of rain tires, an extra set of race wheels and spares and supplies for such a long trip. Steve welded on removable threaded poles to the trailer tongue make let me bring extra race tires on the trailer instead. He did an excellent job and I can now operate the trailer in either configuration (with or without the extra wheels) without too much trouble.

We then put her back on the alignment rack to see if anything had shifted after running on the grippy concrete and sure enough the right rear toe had moved quite a bit with a significant amount of toe in. We suspect this could happen due to the wonky bolt but it also turns out that the forces back there had somehow also slightly bent the little tabs the alignment washers push up against. Steve hammered them back into place so everything is nice and tight and we replaced all the camber and toe bolts in the rear to restore my alignment back to what it was before Toledo except this time I could actually get the rear toe to 1/16" toe in. Steve's new machine can also take additional measurements of the car so we noted those down too for future reference in case anything ever shifts.

We pushed the damaged fender out a bit so it looked a bit better and to address this issue, I switched from 15mm spacers to 10mm spacers and now the top of the tire is well within the edge of the fender. As a quick check of the diff health, we drained the fluid and it came out nice and clear with nothing scary (metal or otherwise) coming out. Cheap insurance for the beating we're about to take again in Wilmington.

Other miscellaneous fixes included adding some screws to the rear bumper cover so it stops flapping around after I broke the tabs off from contact. We also added a drop of loctite on the nuts holding the throttle cable in the bracket to address the throttle debacle from Toledo. Thankfully there isn't a lot of stuff we have to do for pre-big race prep anymore. Hopefully we can do better in Wilmington and at the very least get some good set up data before nationals.

Toledo ProSolo...where 100% isn't enough.

It was finally time for the first big event on concrete for Bumblestook this season. All the testing, practice and prep the past few months would be put to the test at Toledo where all that grip would surface any issues around reliability and speed of the car. Practice starts went quite well on Friday. Despite going up to 315s in the rear this year, I was still able to get some wheel spin launching at redline (8600rpm) and overall Bumblestook felt strong and healthy.

We finally got to walk the course and I knew I'd be in trouble. I counted only 4 actual corners where I'd have to lift and it was very likely the other cars in my class wouldn't have to lift either thanks to the massive grip of the concrete surface. It was clearly going to be a power course especially with a hair pin that shuts you down a lot and where torque would be crucial. Without driving the course yet, this was just purely speculation so we'd have to see on day 1 how bad the situation would be.

Sure enough on Saturday, it drove as predicted...flat out in all but 4 corners and riding the rev limiter all over the place. With my top speed in 2nd limited to about 62mph due to gearing, it would be cake walk for the Vettes that could go well over 70mph in 2nd. Shifting to third would be an option but it really didn't help too much. To make matters worse, the grip level allowed me to three wheel the car out of a corner putting more load in the front corner than I had ever tested and the result was carnage on the driver side front fender.

I was able to fix it after the morning session and was ready to give it another shot in the afternoon. Unfortunately, my luck continued to run short. On my first launch, I suddenly lost throttle and the car was just stuck idling. I managed to use the momentum to roll off the course and found that the nuts holding the throttle cable in place had vibrated loose causing the cable to come off. I remounted the bracket but lost all my afternoon runs in the process.

Sunday would be my last chance to redeem myself. There was threat of rain in the horizon but luckily it just skirted around the venue and we were able to get runs in the dry. I managed to drop some significant time on both sides but simply coned away my fast right side runs. Either way, with the course laid out the way it was, even going 100% and not hitting cones still wouldn't be enough to come close to a final trophy spot. The dirty runs tumbled me down in position ending up the worst I had finished this year in 11th out of 15. To add insult to injury, my wheel had touched the fender again this time creating even bigger damage.

Toledo, OH - 6/29/2014

Despite all this, I still had a great time in Toledo. The grip is intoxicating! I verified that Bumblestook could handle the grip and felt well balanced on that surface with no changes to any settings on the car. If the course was designed to be more balanced, I think we would've had a fighting chance so I'm looking forward to the rematch in Wilmington next month where hopefully someone can design an autocross course and not a simple drag race.

Final Prep Before Toledo ProSolo 2014

After the successful testing we had two weeks ago despite the ITB failure, I dropped Bumblestook off at Evans Tuning to have the ITB issue sorted out before the Toledo ProSolo. While it was at the shop, Karcepts released new spherical upper shock mounts. I've been wanting to replace the modified Tein top hats on my Motons for some time now so this was perfect timing. I assumed that my Moton Triples were the same dimensions as the Moton Club Sports so Brian Karwan at Karcepts sent me spacers for those shocks but when Jeff DeVos (JDV) at Evans Tuning tried to install it, we found they wouldn't fit. It turns out the triples were slightly different but thankfully after getting the new dimensions to Brian, he quickly fabricated a new part and shipped it to the shop overnight for perfect fitment and we were back in business. The new top hats a bit narrower and lighter than my previous ones so replacing them actually dropped the car all around for a super hellaflush look (temporary). The ITBs were fixed and reset and TPS recalibrated.

After picking her up from the shop, I dropped her off at SJF Performance for suspension tuning. First Steve took care of the brake bolts that I lost at DC. Robert Thorne sent me new spacers and bolts so he put those in for me..the clearances are super tight on this kit!

Being paranoid about ProSolos, I had Steve change the diff fluid again to handle the abuse I'm about to put her through next weekend.  We also put on the competition set of tires I'll be using for the weekend.

Then it was on to some serious business. First up, with all the weight reduction the car underwent after the NJ Championship Tour and the new top hats, we had to reset the ride height and corner balance. Dave Corsaro is the man for this job and we got the car up to near stock height where I like the car to be (raising all corners around 0.5") and got the corner balance spot on for absolutely perfect cross weights in race trim. With the help of some static weight reduction and running a lot less fuel, Bumblestook dropped a solid 66lbs in race trim from when we won at the DC ProSolo two months ago. On top of that, I dropped 9lbs so in total Bumblestook is now a significant 75lbs lighter than in DC.

Once corner balancing was completed, it was back on the alignment rack for the third alignment of the season. With the ride height slightly altered (rear is a tad lower than before) and the rake set to about 1/4", we got some more caster back in the car (maxed out at around 5 degrees) and a tiny bit more front camber. I asked Steve to compensate by adding another 0.1 degrees of negative camber in the rear and resetting the rear toe back to 1/16" total toe in. Unfortunately, there's some wear in the toe adjustment bolt so it didn't want to set at 0.3 per side, so we kept it at 0.4 which is a tiny bit more than 1/16" toe in. I have to make sure to order new bolts before we realign for Wilmington next month. As always, Steve painstakingly got all the alignment perfectly to spec...and damn, she really needs another wash :(

Alignment #3 - SJF Performance - 6/22/2014

Finally to help manage tire pressure build up in between ProSolo runs, all the tires had the air vacuumed out and replaced with Nitrogen.

Nitrogen fill in tires - 6/22/2014

It was a long weekend but I'm glad that the car is as perfect as she can be for Toledo. Everything was checked and re-checked for 100% performance so it's all up to me to not screw it up. There are no excuses! The concrete and a fairly stacked SPA class will be a true test of how fast Bumblestook and I really are nationally so we can make adjustments if needed before Nationals in 2 months.

ITB Failure, Testing and Winning

After a month off from racing I was excited to get back out there and test the changes we made last month. Softer rear springs, re-alignment and weight reduction. The weekend didn't start off too well though. On my very first run, I got to the first set of corners when suddenly I had no power even at full throttle. I was able to limp her back to grid to inspect what had happened. The throttle linkage for the ITBs had somehow worked its way loose. I thought it was game over. I pulled the return spring out behind it since I was afraid it would fall down and get lost but after closer inspection and with the help of Steve Farkas (SJF Performance), we managed to get the linkage reconnected, leaving the return spring out (not easy to reinstall on the spot). The other return springs were stiff enough that the throttle body performance seemed ok so I took her back out again for a test run and all seemed well. Not wanting to lose a day of testing, I just kept monitoring it after each run and it seemed to be work fine so I continued with testing as planned.

Linkage back in - NNJR SCCA Autox - 6/7/2014

Aside from adjusting the suspension for balance with the new rear springs, I wanted to see how low she could go on fuel without fuel starve to save more weight. We started the event at 6 bars and ended on 3 bars, well under quarter tank and did not get any fuel starve. Surprisingly I didn't need to make too many changes from my previous setup. As expected, the 10% softer rear spring helped add some mechanical grip back there to make her more stable and easier to drive under throttle. I only had to pull some rear rebound and the balance was back to what I wanted and she could be driven hard under throttle in every corner for rotation without much drama. Despite the early mishap, I was able to get 5th in PAX out of 148 drivers and 6th fastest time overall. The new exhaust is definitely louder than before and sounds more "bee"-like but should be within the sound limits for the SCCA.

Day 2 testing continued with MSNE in Lot J at the Meadowlands. It's a wavier lot with a bit less grip but there were a lot of good elements to do more testing with including some very fast high-G sweepers to continue my low fuel testing. Ran a quarter tank the entire time with no fuel starve. No changes were made to her settings from the previous day and she was absolutely a blast to drive once I figured out the bad parts of the lot to avoid which unfortunately forced me to take a less than ideal line. At the end of the day, I managed to put down Fastest Time of Day (FTD) overall out of 124 drivers resulting in me getting this ridiculously oversized trophy that I have no place for but more than anything I'm just super stoked that Bumblestook is feeling in prime shape before Toledo.

She now has to go back to Evans Tuning this weekend to sort out the ITB issue, new top hats for the Motons I got from Karcepts have to get installed and new corner balance and alignment with the new reduced weight. She'll be ready for the Toledo ProSolo where I'll try to keep the momentum going and hopefully put up a solid fight against the 14 other drivers in SPA - Street Prepared Index A. It'll be our first event on concrete with the current setup and I hope we can keep it together and do well.
