My car went 13.35 @ 108 w/ a 2.25 60" my first time at the track with it. I had only had the car 3 days by this point. Having never raced a m6 at the track... It had a lid when I got it though... and I added a cutout the day of the track... so times are w/ lid and cutout
Mid 13's is not too bad for an LT1. It's very unusual for them to run that stock though. Are you sure it doesn't have maybe an LT4 intake intread of an LT1 intake?
Unless you're saying maybe it has an LT4 in it the LT4 intake alone is worthless on an LT1.
Methinks there's some mods on that guy's car to run that fast.
My first time at the track lo those many years ago netted 14.2's at 98mph. With an exhaust manifold leak fixed and a muffler the car went 13.82 @ 100.8 a couple months later.
Thats impossible your 96' z28 6spd ran 13.4 - 13.6 in 1/4 mile. I have 97' ss LT1 and heard it's capable of running 14's flat in 1/4 mile. I havent tested it at the track yet, but Im sure its quick cuz I beat a 97' M3 racing on I-80 freeway the other day. My brother used to have a 89' 5.0 GT stang and his stang ran high 13.8's @ the track with all the mods such as ported head, new rocker, springs, and peformance components and 3.73 posi gears. I remember riding with him. His car feels as fast as my stock 97' SS. Its possible to run high 13's with a stock LT1. I know LS1 are capable of running low 13's and high 12's. There's proof of that in GMHighPerformance magazine that a stock 2002 SS can run high 12's in bone stock trim
well i got the GTA to the track. With K&N drop in filter, and a 3 inch catback, shift kit and some LCAs. got a 14.7 @ 94. i need to put some good tires on the car.
I have some tuning and bolt-ons, but nothing to blow your doors off, plus the stereo is a real ET killer w/400# over stock (4060# w/driver) BUT I am consistent between 13.6 - 13.9
Stock I could only muster a 13.6@105, but that's with an M6 on street tires never better than a 2.04 60'. Best time to date 13.23@107 3400lbs w/me with 327RWHP/341RWTQ. Lid w/K & N, Loudmouth exhaust, Z06 clutch, 85MM MAF/bellow. Should be runnin' high 12's WTF?
