I Busted the 12's!
I just got back from the Track. Previous best with 58mm Throttle Body, 44 psi fuel, BOSCH plugs, Bad Opti spark, No Ram Air and NITTO 555R, 315/35/17 DR, stock Tranny was 13.021 at 105.89. This was after I put the new heads, cam, intake, computer and 2800 Torque convertor on. I was a little upset, with the numbers.
Tonight witha 52MM throttle body, 46 psi Fuel, NGK plugs, good opti spark, Ram Air, B&M shift kit and BF Goodridge Comp TA R1, 275/45/17's (I got these from TrueDuals, we thought we could get about 3 passes on them, we were right) I turned a 12.799 at 107.14. That was with the worn 275's spining off the line and again when I hit second. The second and third runs kept getting worse, the tires spun all the way through 1st and a little in second. I turned a 13.176 at 106.37 and the last run was 13.186 at 107.86. I finally gave up, before the tires blew. Once I get the 315/35/17 NITTO's back on and I get the launch down I should be about 12.5 or better.
The Ricer that was talking crap about Vettes a couple of weeks ago was there. He ran a 13.5 at 100. I just waved when he went by. :seeya

Re: I Busted the 12's! (UB2 SLOW)
Nice improvement; what kind of short times did you pull? I assume it's a 6-speed.
BTW, nice job on the "ricer"; I can understand being inflated with your ride's capabilities on the street, but not at the strip.

Just playing with your 60'/1/4 mile et's.
1)1.936=12.799
2)2.173=13.176
3)2.152=13.186
2.173-1.936=.23 so the 12.799+.23=13.02(13.176actual)
2.173-2.152=.02 so the 13.176+.02=13.19(13.186actual)
This is close to what I've always seen! The 60' time is very important for et! :cheers:

Re: I Busted the 12's! (UB2 SLOW)
What was your launch RPM?
I recently went to a 2,000rpm TC (stock was 1,500rpm) but was still launching at the old 1,000rpm. After updating that parameter, Drag2000 told me that I could bring down my short time and ET by launching at 1,600-1,800rpm (the brakes won't hold her any higher).
I've done this on the last two T/T sessions and sure enough it realy helped both time slip data.
Last night I was talking with an experienced drag racer who pointed out that when I launch off idle the TC has to flash up AND the suspension has to react before the car can move forward. But, by launching closer to the stall point, not only the TC doesn't have to flash up so far but also the suspension is pre-loaded so those two lags have been reduced. Also, staging shallow will lower short time and ET.
So, if you're not already doing these things, combined with your new rubber you should see some more improvement in ET, which is already very nice.

Re: I Busted the 12's! (UB2 SLOW)
Congrats on breaking the 12 second barrier (distantly related to the 13 and 14 second barriers)! With your trap speed, your car is capable of approx. 12.50's, so work on that 60' time and you're rockin.
