Arse-Freeze 2010, Saturday Racing 1

Originally from December 14, 2010

It drizzled rain at about 4AM so I got up and pulled a tarp over the trailer, tools, and me. The car was already under a canopy.

Early morning again, everything was wet, but it wasn't raining. You'd think that with a race starting at 10 AM that three hours would be plenty of time to get ready to grid up. Not so. All that little stuff takes time, plus there was the drivers meeting, which is probably unlike driver's meetings at any other type of race. This series provides plenty of material for jokes, and we got plenty of that, but it is also serious, and the law was laid down on things like kids running free in the paddock, fueling procedures, and the three-strikes (three hour penalty) and four strikes (put it back on the trailer) rules. With all that said, and just one hour left before the green flag drops, the mood changes from silly-jovial to serious-jovial. It's time to suit up, and have fun.

Cold, wet, and 170+ cars on track. This would be interesting.


I would take the first stint. I hadn't been on this track in years, and then we drove it in the other direction, and I did not drive in practice on Friday, but I was the most experienced driver among us. This race would be starting on wet pavement, with over 170 cars on track, so senior wisdom, or timidy, was needed. My goal, survive the start, so we could finish the weekend.



Yes, that's 170! That leaves about 50 feet per car. Turn 1 after the green flag could be a real mess. After a few laps under caution while cars filed out on track I started looking around, and there were cars as far as I could see front, rear, and around the bend and going the other direction. What a circus! And behind me was the Maserati. The big, old, Maserati. I wondered what kind of brakes it had and if the driver knew how to use them. During the remaining yellow flag laps I would survey the course for good bail-out areas to use if the traffic behind me looked like it was going to crush the little yellow Opel.

Then Zep came on the radio, "Green flag!". I was stuck in the esses, in third gear. I wasn't going anywhere just yet. One car did bolt and passed a few of us. I stayed in traffic as we picked up speed.

First turn, everyone was cautious. The track had dried a bit, but the cars and drivers were cold. Second turn, turn 1, at the end of a long straight, the perfect place for testing crumple zones, which the Opel does not have, and it was all good. No one that I saw was trying to win the race yet. Turns 2 and 3, a kink to the left followed by a really tight banked 180 degree left turn, a place where all weekend people would try to stuff as many cars into as could fit, was good. Everyone was giving everyone else room. Weird. Either I am stuck in a pack of scared ****less rookie drivers or a pack of seasoned pros, because this was good clean endurance racing. So far.

I took it easy for the first hour. The track was still drying out and the car bogged really badly, bad enough to keep me from finding any rhythm or even feeling like I could count on the car. Odd how a sick engine can make you drive like the whole car was sick. But I stuck with it, rolling through the turns quicker, going easy on it in the braking zones, and pretty much just letting everyone pass me. I'd just let this be my practice day, and I'd try to diagnose the engine.


About an hour or so in I picked up my pace. My early laps were in the 2:50-3:00 range, which is really slow, and a bit depressing. Just the fact that you spend so much of your time in the mirrors and staying out of people's way keeps you from finding your own pace. But a lot of the early slow lapping that was due to the many cautions. The field was thinning quickly. Two or three cars didn't even make it to the green flag and had to be towed off, never to be seen on track again. During the first few laps I'd guess about 8-10 more cars got towed off, but many of them would return to racing after making repairs. There was rarely a lap that didn't have a caution flag out at some corner.

Note to potential LeMons drives, if you miss a yellow flag and pass someone, you get black flagged. Get three of them and you park the car for three hours. Get four and the whole team is out of the race. So with so many yellow flags flying, this was a pretty treacherous part of the race.

At some point the engine bog didn't bother me any more. And traffic had thinned. And there weren't so many caution flags. And I picked up the pace, dropping it to as low as 2:33, our team's best lap time. And I was having fracking fun! Man this car is balanced, and it sticks. Hard braking into the kink at Cotton Corners, letting turning slow the car further, grab second and shot over the rise, drifting it momentarily through Grapevine, grabbing third, full throttle through the right turn at Club Corner, wide arc and just a slight lift for the next left into the Bus Stop, knock off some speed for the left kink exiting the Bus Stop and into Riverside, holding the throttle open in third through this long banked turn, and really feeling the G's. Hold it as the banking ends, wary of how that would affect grip, grab fourth and fly down the Drag Strip to the next turn Sweeper, a tight right-hand 180, but with pavement continuing straight if you screwed up and needed a safe run-off area. Hard braking, blip and downshift into third, trail brake my turn-in, enter on the inside and sweep out so that I could hold my speed for the hook that led out onto the Esses. Full throttle through the Esses, grab fourth for a few seconds, downshift, brake hard, left through Sunset and onto the front straight. Hold third as long as the car still pulled, then fourth, then hard braking, downshift, and left, full throttle through the kink then to the tight banked Off Ramp, which by now had mud all over the entry point and after the exit. Slip and slide a little on entry, grab second and go, slip and slide a little on exit, grab third, and do it all over again, and again. Awesome! Much better than sex.

It was going great. I was passing people who had passed me all morning, and was still getting passed by the guys who actually had a chance of winning. I was driving the car well, not hurting it, not making any mistakes, leaving plenty of margin all 'round so that car would last, and at one point I remember thinking, wow, I feel like I am at work, doing a job I love, and I could do this all day, no problem.

Then coming over the hump after Cotton Corners something broke. The engine was really loud. All I could hear was engine. A quick look at the gauges and all looked good. A quick look in the mirrors and there was no smoke. Throttle? The engine responds. The gauges still look good. I must have broken the exhaust. Should I stay out? Wait to get black flagged? What if the exhaust hit the pavement? What if the hot exhaust gasses managed to do its thing to the oil we had coated the bottom of the car with on Friday? On the radio, I'm coming in, probably a broken exhaust. I back off the speed and finish the lap and head for our pits. Geoff and Zep are there. I feel for the teams that don't have radios. I park, engine running, and they immediately confirm that the exhaust broke right behind the header flange. Geoff heads for the Evil Genius pits on bike and radios back to bring the car over. Clint will fix it. Zep drives it over while I unwind and get out of my suit. Man, my arms are sore. How long was I out there? By the time I going them at the EGR pits they are almost done. Clint is finishing the welding and Geoff is under that car with him tightening the header flange bolts. Meanwhile, Zep is back in our pits getting dressed and ready for his first stint.

I still owe Clint dinner.

Buttonwillow Feedback

Originally from December 8-13, 2010

Guys, congrats on the achievement...3rd in class is awesome. I think that I might have a solution to your helmet head clearance issue...albeit, stolen from the Ford GT-40 project. From what I recall, there was one tall driver of the original race team that required a "bubble" over his head on the roof of his car. Perhaps the carb. bubble from your parts car hood could be fit on the roof in the right position to help your problem.

Also, from the same car...I've been thinking about the idea of utilizing the hood "vent" idea over the radiator for increased cooling. I wasn't going to share that until I tried it first, but it just seems logical for a racing application. - Ken2, OpeltGT.com

Thanks. And "C" class was pretty big, too!

We've considered the Gurney bubble but figured that the Lemons tech folks would end up forcing us to modify the roll bar to match. We're probably going to cut the floor out and lower the seat instead.

I've wanted to do the hood vent ala ALMS Corvette for theme reasons and for cooling, but mostly for theme. If we do it, it has to look good, be well done. No Lemons sawz-all hack. Alan is not sold on that yet so it's on the back burner. We can also lift the hood near the windshield to let more air through. We are definitely going to look into re-coring the radiator or getting another one.

I've reviewing the video now. We have about 52 hours (110 GB) of video to sort through but so far it looks great. I'll try to get up a sample tonight.

I am totally impressed with your performance. We ran at Buttonwillow last year and could not even finish. Most people have no idea the preparation that is needed to keep an old car running flat out for two days. We wanted to return to Buttonwillow but we just ran at Willow Springs in the Chumpcar 10 hour race. With the holidays in full swing the wives said no more this year. Hope to see you at a race in 2011. – Ralph Coates, OpelGT.com

It would be so cool having two Opels on track together, or rather, at the same time, since we'd be competing. Should we agree now that just because one of us may end our weekend early that that doesn't automatically make the dead car a parts car? And maybe Jay should create a new class for us, class "O", for "Oh good God not another Opel". [top secret]If Alan's plan comes through there may be three by this time next year.[/top secret]

And many thanks for the compliments. It does take a lot of effort, and we have loved every minute of it and treasure every scar. Well, Alan treasures his scar.

I gather yours was the red Opel with the missing belly pan. It looked great in the photos I have seen, but I heard it had heat problems, and that it was sporting a V6. I think there was also a V6-powered Opel GT running back east that did not finish due to temperature problems, and now there is a new team preparing an ALMS-themed GT for the Texas races. They've got a thread here somewhere.

We had heat problems, and oil gusher (note merely leaks) problems, and bogging and shooting flames out of the tail pipe problems (Someone came by our spot in the paddock to compliment us on our awesome tune, not realizing we had an anti-awesome tune.) and we broke yet another tranny, but we finished.

We got some carburetion/timing tips from some passing drunks, er, revelers, on Saturday night that solved major problems for us. We also brought a spare tranny, again, and by now we have lots of experience swapping these things. We also went through four, maybe five quarts of oil, and we know where 3 of them went.

We were running an electric fan and the old radiator. We had to back off once the car started getting hot but it seemed OK with water temps at 210F all day. Oil temps were similar. We've got to make this better or else we are doomed for summer races.

I still can't decide if we are good or lucky. If good, we owe a lot of that to OGTS and to the OpelGT.com forum. On the luck side, the car had little rust and the motor has run great for two races and three track days after sitting in a field for 25 years. All we've done to is it change the oil and spark plugs and recently started putting in gaskets to help keep the oil in the engine, not on the engine, or dripping off the whole left side bottom of the car.

But seriously, I think the biggest thing our team has had going for it is our willingness to go out and ask the dumb questions. Oh, and read the manuals, which is actually Alan's job.

We're considering either re-coring or replacing our radiator, and maybe replacing the current water pump with a new one we have laying around.

We may also move the radiator forward a bit, ahead of the bulkhead it is now mounted on, to give us room to mount the electric fan behind it instead in front where it is now. Ford Cook gave us a stronger fan so we might switch to it.

I think I'll also go ahead with the splitter idea. It should help get more air in the nose and it will help complete the ALMS Corvette look.

We already have an air cooler in the nose so sticking a second radiator in the car will be difficult. If the above changes don't fix this for us then getting a larger radiator and mounting it at an angle seems to be our last option. Taking the hood off is not a good idea because of the crap you get on the windshield, plus I think 2011 LeMons rules now require an OE hood.


Short Report from Buttonwillow

Originally from December 6, 2010

Here's my short version of the weekend:
  • We finished!
  • We finished 58th out of 174, exactly at the 1/3 mark
  • We finished 3rd in class, the slow class.
  • We got one of the two Grassroots Motorsports "Most from the Least" Awards.
  • We got a "Most Beautiful Car in the Race Award" from a woman who was going around the paddock with here boyfriend finding cars she liked to give awards to. Really sweet.
  • We broke the exhaust Saturday morning but Clint fixed it for us. I owe you dinner Clint.
  • The carburetion sucked all Saturday but we got it working much better that night.
  • The tranny got stuck in 3rd gear and Geoff had to finish out the Saturday for us using only 3rd gear. We swapped in our spare that night.
  • Nothing broke or went wrong on Sunday.
  • No penalties, not mistakes. Good clean, if slow, driving. But then slow is relative. There were 116 cars slower than us, or broken, or too many penalties.
And here's a heroic-looking photo of us on track.

My helmet kept hitting the roll bar over the door, especially when cornering in the parts where the track was rougher, like Cotton Corners. It got a bit irritating after a while but I learned to accept it. At least it was reducing the work my neck had to do to keep my head on and upright.

Once while driving I checked the clearance with the roof by putting fitting my fingers between the helmet and roof and I had very little room for my fingers there. It must have been worse for Zep.

Stats
First, the stats, us, the leaders, and the two Evil Genius cars.
  • #760, POS Racing (the F'edUp car), 1st place, 312 laps, 2:14.4 fastest lap
  • #111, Eyesore Racing, 2nd place (40 seconds behind the leader), 312 laps, 2:12.7 fastest lap
  • #95, Model T GT, 9th place, 295 laps, 2:10.9 fastest lap
  • #8, Team Tinyvette, 58th place, 222 laps, 2:33.9 fastest lap
  • #34, California Mille (Red-white-green Alfa, Brian's nemesis, see the Germany vs Italy video on Vimeo), 69th place, 216 laps, 2:16.5 fastest lap
  • #94, Communism R Us, 90th place, 179 laps, 2:27.8 fastest lap
  • #745, The Color of Money (EGR Volvo), 93rd place, 178 laps, 2:21.2 fastest lap
Last stat - we finished third in class, the slow class, but still, third is pretty good, right?

Report Just in from Buttonwillow!

Originally from December 5, 2010 - Alan Reporting

Team Tinyvette has taken the Checkered Flag at the 24 Hours of Lemons Race at Buttonwillow with a third place class finish! Great driving job by Mike, Geoff, and Zep!!

The Tinyvette was awarded the Grassroots Motorsports Magazine Award for the car that delivered the Most from the Least!! and another award for the Best Looking Most Beautiful Car in the race. Jay Lamm again expressed his profound surprise that an Opel could finish a LeMons race.

No penalties and no black flags, just good clean racing. The car had no mechanical pit stops or repairs during the race. But the team did swap trannies overnight for the second day. (Anybody want to donate a Getrag???)

I'm sure Mike will be posting a complete description of the race after he gets a good night's sleep and starts to come down from his current state of extreme joy and excitement.

Ready for Buttonwillow

Originally from December 2, 2010

You guys should drive the Tinyvette a bit to see what our experience has been like. With it stripped bare and riding a bit rough you might not think you are in an Opel GT. It feels more like a 55 gallon drum on wheels to me. But then I still haven't driven a street Opel GT so I don't know what they are supposed to feel like.

More fun than pain.

We're packed and after an errand downtown the Tinyvette goes on the trailer and we are off to Buttonwillow.

You guys do a no-rain dance for us, OK?

Oil Leaks and the Neighbors


Originally from November 30, 2010

I got the car off the jack stands yesterday and drove it around a bit. Shifts fine, the tranny feels good, and the car feels good, except that it bogs on throttle application. We'll try to get to that today or tomorrow or all throughout the race weekend.

Oil pressure seems a bit low, which has me a bit concerned. 37 psi at 2500 rpm, just under 25 psi at idle.

And we have a small leak up near the new oil cooler. We also had a bigger leak out the front pulley area that was odd. It did not leak while running the motor. We didn't see oil sprayed all over, just puddling under the car and on the cross member after we parked it. There will trails of the drips on the pulley. And behind the pulley everything was dry, so it probably was not problem with the seal. Could oil be leaking out the key-way, or under the little shim thin we slipped over the pulley to get a good seal? We removed the pulley, put gasket sealer everywhere oil could possibly get through, found a good washer and put it back together and run the motor until warm, and our neighbor complained. So far no leaks, but we still have our neighbor to keep happy.

Today we put in the wiper motor we've borrowed from Alan's car and will finish hooking up the headlights. Rain is very likely during this race.

Other than that, we're learning to ignore the odd rattles and noises and getting to appreciate how primitive this car is.

Almost Ready for Arse-Sweat

Originally from November 29, 2010

Tranny 1 of 5 has been rebuilt. We robbed the synchro out of tranny 2, which now will not get repaired because some stuff in it was broken.

We'll be working on tranny 2 today and that's what we'll take with us as a spare. They are certainly small enough that would could take a bunch.

We've got 2 DVR's in the car now, that's four cameras: in-car front and driver, on-car rear and roof views. Editing should be fun.

A little carburetor work and fixing the fuel spill problem and we're ready to go.

Oh, except for the new decals.
