I raced a like 2001-2003 Vortech Mustag making mid 500rwhp, he ran 11.6x @ 126...I was a head of him until somewhere between the 1/8th and the end of the 1/4 my traction control kicked in and shut me down...it did this twice. We were running 18" C5 Z06 wheels with 295/35 BFG DR's. My 60' was 1.84, 1/8th 7.475 @ 95.3 and 1/4 11.7 @ 103...he ran 1.93 60', 7.676 @ 94.9 1/8th, and 11.63 @ 125.98....Had my stupid TC not stepped in, based on my 1/8th I would have ran 11.4-11.5 @ 125-126mph. This and the other run where this happened were performed with both TC and Stabilitrac "ON"...it was giving me the best 60' to do it this way. I did try a run with everything OFF, but both times 1) didn't hit it hard enough out of the hole, 2) left it in manual shift mode and I botched the shift (started in 2nd gear on this run and it resulted in a decent 60').

Long story short best ET 11.7 Best MPH 123...Neither are at the cars limits, on a perfect pass, 11.5 @ 125 (at least) should be available. I'll have to try another night...

Timeslips and video's will follow tomorrow or Sunday.


At least for now, I think that is the fastest and quickest L99 posted to date? Probably only until Matt gets his car going with the blower and cam.

Here is a video showing my issue...watch the brake lights come on before the end of the track...we'll before the mustang in the other lane...this is were the TC kicked in and shut me down...all my warning ligts in the dash came on ...BRAKE, ANTILOCK, Service stabilitrack, stabilitrac, low traction etc

Nice time's You should be 11.2-11.4 no problem ...

Brad, I'm pretty sure if you had a different wheel/tire on the back you can go 11.2x.
Some one got a stall converter ...
