Quickest/Fastest L99 so far?? *ET 11.7 *MPH 123

To make a long story short because I'm tired and have to go to work in the AM...just got back from the track. I have an official timeslip with my car running 11.7 and another trapping 123mph...we are having some technical issues, the car has more left in it for sure. 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

Awesome times - I hope you get the TC thing figured out soon, as I am sue you will. It is great to see these cars running such good times with the maggie. Do you recommend trying to launch in 2nd gear or just start in first and roll into the clutch? I just have stock tires but I would love to break into the 11's as is. Next year I'll get some DR and see what I can do. Again - great run!!

I'll be at the track next Wednesday to try out, however, I do not have DR's or 18" wheels, not to count that I don't know how to best launch this car. Thanks for the input on your take off, I will try it like you did to see how it does.

Good Job!

I went 11.8 @ 115 with my L99, so you got me beat. I have a few things to try out still, I'm trying to go 11.5 on the stock heads and shortblock with just a cam and bolt ons without any weight reduction.
Brad, I'm pretty sure if you had a different wheel/tire on the back you can go 11.2x.

Thanks for the info Mike, I'll be talking to my wheel/tire guy and see if we can't round up a set of those for our next outing. I'm gonna look into a snow Meth kit and we still probably need to upgrade the fuel system at some point.

I think you were on point in your PM about the 18's though, that is exactly what happened.

On my best run the DA was still +2000, later that evening I'm sure it
Went down but it only resulted in more traction issues. Late this fall
I will return with different tires and a few small tweaks that will hopefully
Result in both better ET and mph

Not for the quoted runs....the best DA of the evening was/were on the runs where the TC kicked in and cut my throttle at the 1000ft mark. My tuner was working overtime trying to help a few other guys at the track so we said we'd just run the 18's with no tune adjustment and see what happened...THAT is what happened. I'm gonna try to get some 20" Nittos and go back and see where i land. This car wasn't really designed to be a drag car, I dont even have stall, so whatever it does from here will really be a pleasant surprise.

Just ran a 12.4 @113.5 mph with a crappy hole shot!

I couldn't seem to get the timing right tonight, but hopefully I will get use to it. I will get it into the 11's next time.

Here is the video from inside the car and the timeslip.

Nice run - I am sure you will get it figured out and into the 11's. I ran a 12.4 last week at our strip here in SD, but unfortunately it was the last track night of the year around here. Drag radials next year and into the 11's I should go.

It is hard to get a good 60' on stock tires at the track - especially when it is not prepped. I have never been able to get under a 2.0 60' time yet but with DR, maybe. Looking forward to next year. Good luck at the track again and I can't wait to see your results.
