focusmaniaczx3 i would blame that entirely on track prep then. if you launch properly on a properly prepped track you shouldnt be blowing off the tires like that if you have the pressure down to that level. try a different track where the big boys play.

sporadic Couldn't get better than 2.0 60' this weekend, even dropping the PSI to 11.5.
I have two primary issues I believe.
1) Can't get a good burnout because my ebrake doesn't hold the car back.
2) Tons of low-end torque from a small turbo blows the tires off on launch.

Even slipping, launching off basically idle it spins the tires when I went WOT.
The best 60' times resulted in 4K RPM launches with very little clutch slipping.
I do question the track prep though. I saw no VHT used on the track, and they were bad about keeping the water box wet. (it was a track rental day)

At any rate I blew away my previous best of a 14.11 with a 13.63.
Hopefully next year I can see some low 13's.

focusmaniaczx3 you should be able to hit that time on BFG radials. brief hazing on 13-18psi, pre load the suspension by slipping the clutch and holding the e-brake and launch on the last yellow. you SHOULD be able to get your goal.

sporadic 2.0 does not seem good to me for a racing compound tire, even on a FWD.
I know I'm used to RWD drag racing, but the difference between a 1.85 60' that I want and 2.0 is huge.
I guess when I hit the track on the 24th I'll find out.

FiFoci Idk if my track is preped well or what. But i ran my BFG's at 32 psi (no joke) i would do 2nd gear burnouts thru the water.
Slipped my clutch around 3k while holding the ebrake then drop it all on the last amber. I dyno'd 244hp 265tq and i was hitting consistant 2.0 60s. with almost no wheel spin. For some reason 32psi was working great and i didnt have to add air for the drive home lol.

focusmaniaczx3 ok was just curious. its always kind of been strange for me to hear about guys going to the track and doing everything they possibly can to get out of the hole better and the best they can do is 2.2-2.3 on wider than factory tires. i forgot to mention that i did the 2.0 before i got LSD. ive not been to the track with my 18x7.5's on the front since i got tom to put the transmission together nearly 2 years ago. 2 reasons for this. i can make up the time i loose out of the hole on the big end with the lighter factory wheels and tires. the 18s really slow it down badly. and also tires are ALOT cheaper for the 15s so i dont feel so bad about making a little smoke show every time i go through the water box even though i dont have to.

45psi? No. I've certainly cut 2.0 60' times on street tires though.
A lot of that depends on the track prep and also track conditions.
There are freak tracks that are VERY well maintained and also at sea level that will yield amazing 60' times, ET, and mph.
I knew a guy that would cut 1.85 60' times on street tires at his track with his '03 Mach 1, but certainly not at my local track!
My track is at 1250' and a 2.0 60' is great on street tires for a RWD.
