Went to Atco - New PB

Went to Atco on Saturday for a little T&T. This is with the new trans and E85. Since I was away for almost 2 weeks, I didn't have the chance to fine tune my fueling and see where the widwband gauge was reading. That is what T&T is for i guess. LOL

My main goal was to take it easy with the E85 since I had no idea how it would be and also because I haven't been to the track in a while. Didn't want to touch the boost or timing. Wanted to get my fueling right first.

1st run - [email protected], 1.8 60', 19 PSI, stock timing, 12.6 AF, cutout closed

2nd run - [email protected], 1,77 60', 19 PSI, stock timing, 12.1 AF, cutout closed

3rd run - [email protected], 1.75 60', 19 PSI, stock timing, 11.9 AF, cutout closed

4th run - 11.17@ 124.71, 1.74 60', 19 PSI, stock timing, 12.2 AF, cutout open

5th run (hot lapped) - I messed up. After burnout, I never took it out of 1st gear. DOH!

6th run (hot lapped) - [email protected], 1.76 60', 19 PSI, stock timing, 11.9 AF, cutout closed

0 KR!!!

The car felt very strong and fast. There is more in her since I didn't touch the timing or boost. Still have to get the AF right which is close. 10's will happen.

I think I need new slick. I spun every time I launched. I havd only 2 good burnouts. It could be I had too little air in them (11 psi) or they are worn out. The indicators are gone.

suprised you did not run faster on the 12.5+ afr runs... I have found I made more power up there than when it was in the 11s, but I never had a good test at the track.

I will probably try to keep in the high 11s from now on.

I might stay away from anything higher than 21 degrees of timing or so, and start cranking boost... I was up to 27psi and 26 degrees of timing with E85 last year on a ST2/PT67.
 
Very nice runs! Full weight correct? How was the DA'?

10s are in the sixty foot. If the indicators are gone im surprised you pulled the '60s you did.
 


Good runs Sal.

Glad to see ya back at it...always loved that car.

Thx. It's been over a year since I raced. I missed it.

My car runs best around 11.5-11.7 with the E85. I'll keep that in mind about the timing.

That's crazy amount of boost and timing. What was your PB? Also what tires were you running?

about 3600 with me in it. Full interior minus passenger seat.with 8 point roll cage and racing seat.

Don't remember the DA. Was in the low 40's I think. Had a head wind also.

Right now I have MT ET slicks. I'm thinking of changing to Hoosier drag radials.

PB was a 6.32 @ 115 1/8 letting out quite a bit before the 1/8... Never got another run in, then blew a headgasket the next weekend (after) racing a modded zr1. No, the zr1 didnt even stand a chance nor did he keep up 60-140. I have some 8.5x26 ET Drags on the back... trying to shoehorn on some 10.5 x 28s right now.
 
Sweet lord Jesus.


This is a bad mfkr. I see this car running 10.8's with a low 1.6 60 and mid tens with boost & timing along with a good launch. Great work.
