9/9 CART Auto-x

This past Sunday I participated in an Auto-x put on by CART CT. CART stands for connecicut auto-x and rally team.

The day of the event I was quite tired. I spent the day before on 4 hrs of sleep and swimming for 9hrs. Then I drove 5hrs home, got in the Evo and drove to Matt's. Matt was out with his friends, so when they got back we stayed up for a bit. Needless to say, I didn't get to bed till 2am on Sunday.

We awoke at 730, got some coffee and food from D&D. At 8 we were at the auto-x changing tires and getting ready to register. I'm sure most of you remember how I was kicked out of the last auto-x for noise. Well I made a baffle with steel wool, 4 bolts and 3 tuna can lids. I had to go through tech but they never mentioned anything about my exhaust. I had two people come up to me asking if I needed a co driver for the day. Nope, I already had one. I was letting Matt drive my car with me for the day. I have to repay him for letting me drive his car two weeks ago.

The course has a good start where I can launch the car, it bends left to a sweeper, then tucks in and has a quick slalom to a short straight. The straight leads to an increasing radius left hander. Once threw the left hander, its a right hand sweeper that really tightens up before the cones shoot you left to the finish. Its a very short course. After walking it once I determine FTD will be 25-26 seconds.

Of the cars present, there were two nicely BP cars, a Corvair and 65ish Stingray. These cars were set up nicely for auto-x. Also there was Jim in his SM STi (my main competition for class), Nick in his SM2 350z (has all but 2 FTD's this year) and a very fast AS class. Matt's friend Dan in his prepared Mustang.

The group always runs novice first to scrub off the course for us. Nick then makes his first run and puts down a slow 34.xxx. My first run I got easy and put out a 27.7. Matt follows up with an O/C. Where Jim puts down a 27.721. I check the tires and notice the fronts are still rollin over so I increase the pressure and soften the front shocks.

My 2nd run nets a 26.701, good enough for FTD at that point. I beat Nick's best run at the point. Matt runs a 27.99 to move to 3rd in class as Jim improves to a 27.5. My 3rd run I run a 26.9. I over drove the car this time. The car didn't seem like it wanted to turn in. I've found my car right now, won't turn in, but it gets snap over steer. This all has to do with my suspension not being set up ideally.

Nice mean while makes his 3rd run and hits a 26.699, damn it, .002 seconds faster. This makes me drive even harder. I can only muster a 26.8 and another 26.9. Matt meanwhile is getting better.

He hits 27.124, good enough for 2nd in class. Jim on his final run runs a 27.164. .04 second difference. Matt and I both beat the SM points leader in a car we haven't raced before.

Now before you jump off and say I drive it all the time. I have not raced the car on the new wider tires and suspesion set up. So its basically like driving a new car.

Nick was able to drop down to a 26.387. His car turns and sticks like its on fly paper. I talk to him afterwards to find he is running -3.5deg camber front and -2.5 rear. I'm only running -2.5 and -1.0 respectably.

In talking to other Evo auto-x, my suspension needs to make some major changes. The springs need to be swapped around. I have 8kg front and 6kg rear. I need stiffer rear. I also need more camber up front, about 1.0deg toe in up front and my rear toe out need to come back in.

There's always some thing isn't there.

So and the end of the day, I take SM class win and 2nd in FTD. Matt takes 2nd in class and 3rd in FTD.
