Tony, Dave and myself competed in the True Street race in Joliet this weekend. The event is a 30 mile cruise, followed by 3 back-to-back-to-back passed. They give awards to the fastest average overall and then for closest average to each index without going faster. The indexs are each whole number from 10.0 to 15.0. During qualifying, I had seen several cars consistantly running close to the 12 second index I would be competing. Since I'm still running a stock IC, I pretty much knew my first pass had to be an 11.9x. Well it wasn't. I ran a 12.07. Surprisingly, I ran faster on my 2nd pass with a 12.019....go figure :rolleyes: My 3rd run was a 12.04x, netting me an average of 12.043 (going from memory for the runs and average). The winner of the class was a front-engine, ls2 powered Corvair. who's average was a 12.027. I really never expected to finish 2nd in a class that last-year's top 3 finished with 12.001, 12.002 and 12.005 averages.

I'm pretty happy with the car's performance. My race weight was 3975 and I was still rolling my extremely heavy Foose 19 x 8.5 wheels on the front. I did yank the passenger seat though. I was a bit concerned that my meth. reservoir wasn't going to be big enough for three consecutive passes, but early testing during qualifying proved otherwise.

Wow, this has to be a first. Generally your car loses a good second from beginning to end of a race day. :p

Nice going!

On another note, looks like you better start working on your next mod so you can put the smacketh down on David in Pro Street later on this summer.....

Those are great results Kurt!! And excellent numbers. Can't wait to see what the car will do when it gets a little cooler out (say in Oct) ;) Guess you have to run Pro Street this year. Just remember to leave the tires in the trunk again :D

Maybe the location of my SNOW nozzle isn't as bad as we think :rolleyes:

Actually, if I put my passenger seat back in, along with the spare and the jack, 12.10's look pretty good ;)

Since I was only teched for an 11.50 ET I had to make sure I didn't go any quicker than that until the last of the 3 pssses. Oh yeah...I failed tech for not having a working horn. Apparently those guys at forced fab who did the turbo system back in 2005 removed them :mad: Tony and one of his brother's freinds helped me locate the wiring for the horn and the horn from Tony's Ranger (zip tied under the front bumper) worked fine to get me past tech..Thanks Tony.

Anyhow I wanted to see how the car would run just like I drive it on the street except for a set of drag radials on the back. I made a test and tune pass on Saturday and launching soft and then letting off at the 1/8 mile it ran a 12.37 @ 79 mph. Since we had to cruise for 30 miles then make 3 back to back passes I was a little concerned about not have enough fuel in the tank to make all 3 passes. If I race it with less than 1/2 a tank it starts starving for fuel and bucking in the top end and my gauge was only showing 3/4s full.

So I bought 2.3 gallons of the lowest octane fuel they sold at the track (Rocket 100 unleaded) and added it to what I already had in the tank. Since I had the race fuel I decided to add a little more boost and gave the controller one full rotation...which I quickly decided was a bad idea since I don't know exactly how much boost that would add....so I back it off a half turn :o

At the driver's meeting I asked what would happen if you went quicker than what you were teched to run...NMRA guy said anyone who ran a lot faster than what they had safety gear for would feel his rath. I took that to mean banned from racing in future NMRA events. So I asked him just how much leway was he going to give the drivers ? He said no more than 10% quicker on one pass. 10% is 1.15 seconds quicker for my car :D Just to be sure I went back and asked him after the drivers meeting if I could indeed run a 10.4 one time without getting in trouble..he said yes.

Since I wasn't really interested hitting a specific index number like Kurt and Tony were trying to do, my plan was simply not to go quicker than 11.5 until the last pass. Car ran fine on the cruise and never got hotter than 195 even doing a couple rolling burnouts for the media guys covering the event. It also was pretty cool getting to make about 10 laps around the NASCAR 1.5 mile track.

First pass I didn't stay on the trans brake long enough to build any boost and hit the rev limiter on the 1-2 shift and then let off at the 1/8 mile mark resulting in a 12.48 @ 84.87 (1/8 mile was 7.58 @ 101.21). Second pass was pretty much the same except I sat on the trans brake long enough to build some boost and launched with 5 psi and short shifted to avoid hitting the rev limiter and stayed on the throttle a little too long resulting in an 11.23 @ 101.64 (1/8 mile was 7.03 @ 104.40) Oooops didn't intend to go quite that quick.

Last pass I did the same thing as the second pass but didn't let off until clearing the 1/4 mile mark. Unfortunately I was on the 6800 rpm rev limiter for the last 100-150 ft but still managed a 10.82 @ 130.05 (1/8 mile was 7.05 @ 103.47). I'm guessing the half turn on the boost controller was good for about 1.5 pounds of boost over the usual 14.5-15.0 pounds I normally drive it on the street with, so it wasn't exactly raced in street trim, but is was at full weight with the Cobra Rs and spare tire in the trunk. I was also very pleased that nothing broke.

Kathy and I had a great time and are planning to attend again next year.

Thanks guys. It was nice getting a little respect from the announcer too. He mentioned the V6, cruise, AC, leather, tilt, etc. I still need to watch the videos so I can hear all of the commentary. Anyway, here are the details from my fastest pass of the weekend.

60' ---- 1.680
330 --- 4.911
1/8 --- 7.623
MPH -- 90.47
1000 -- 9.963
1/4 --- 11.939
MPH -- 114.14

i too was out there but did not run in the true street. i ran in Modular Muscle class. its an open comp format where you take your fastest qualifying time and subtract .10 and that becomes your dial in for all elimination passes.


here is how i did...

dial ----------------------------------------------------- 12.40
r/t --------- .951 ------ .837 -------- 2.339 -------- .926
60' ------- 1.853 ----- 1.921 ------- 1.639 -------- 1.662
330 ------ 5.741 ----- 5.755 ------- 5.045 -------- 5.048
1/8 ------- 9.168 ----- 8.932 ------- 7.855 ------- 7.860
mph ------ 70.65 ----- 76.00 ------- 87.15 ------- 87.18
1000 ---- 12.097 ---- 11.715 ----- 10.304 ------ 10.302
1/4 ------ 14.525 ---- 14.072 ----- 12.503 ------ 12.410
mph ------ 92.10 ----- 91.81 ------- 92.59 ------ 103.95

prior to these runs the best pass i have made was a 12.90@107 I have a bunch of work to do on my starting line routine and shifting i should better these times by a few tenths or so.

yea .500 pro tree. i havent been on a track in almost 5 years these were really just test passes for me. the first one was just a shake down run and the second would have been a decent pass if i had turned the n2o on, oops. R/T will come around once i get a different transbrake. this one is way lazy when you let off the button

Not sure if it's a good idea for me to go to the track that close to the Shooutout again. Didn't work out so good, when doing that last year :(
