Just got back from Rock Falls Raceway. The day was up and down, but all in all I'm quite happy. First couple runs were very disappointing, right around 14.85. My 3rd run not sure what happened, but the clutch was slipping like crazy, so I pulled into the pits and let her cool down a bit. Thought I broke something, but maybe it just got overheated or glazed over. Whoops, forgot to take out the floor mat, MUCH better!

I ran a 14.337 (Ok, 14.34) at 96.24 MPH. Very pleased with that time! Keep in mind, I have base timing still set at 10*, haven't advanced it to 12* like has been recommended. Also, still have both my front and rear sway bars.

2nd time I thought I broke the car, I got to the end of the track and was told to pull over. Looked underneath, oil EVERYWHERE. At first I thought a tranny seal went, got into the pits and it turned out my oil dipstick blew out and shot oil out. Got her cleaned up, zip-tied that bad boy down and was ready to go.

The air temp climbed and I never did get any faster, but I think the car had another tenth or so as it stood. With advancing the timing, who knows.

I found that my best times happened when I barely spun the tires in the burnout box, then spun right off the line. I had a problem with bogging down, I think I coulda picked up a little time there too. All in all, a great day at the track. Nothing broke, came home safe, and almost went a whole second faster than last year :thumbup:

I'll have some videos soon.

Congrats. Please take a look at your listing in the Top 25 list and let me know of any mistakes. Also some track info (temp, humidity, etc) and other car-type entries would be nice. Please email or PM them to me.

Nice running Aaron. Try a little more timing, you could pick up a tenth or 2.

That's great. You got more for sure in the 60'. Did you have the boost up to 20# or more?

Pete, next time I hit the track I will have my ported/polished/gutted intakes from 40Bob, and 12* base timing. I think that, plus a couple good launches, will get me my 13.90. So close as it is...

Sluggo, boost was peaking at 20-21 PSI. I have a couple videos I will post on google video for you to see.

Where's the weight transfer? The body looks to stay level until you hit 2nd gear. Did you fool with the shocks or front sway bar? If you could transfer some more weight to the rear you could leave harder.
