if you can drive the car i don't see high 12s out of the equation. but on street tires with stock exhaust...i don't see it being easy.

i'd guess 13.0-13.2 @ 106-108..

Yeah they are street tires 275s. Would hope I could do better then 13s but don't have long tubes or a ory yet I guess that's what is holding the car back

Stick or automatic? If it's a 6speed you are going to torch street tires. You should post your results afterwards. I am taking mine to the track(Virginia Motorsports Park) for the first time next Friday. Run plenty of cars but this will be the first time for my newest project.

6 speed M6 t56 upgraded with Kevlar synchros stock clutch and hydrolics removed clutch spring. Yeah I'll post my best time up first manual car at the track

I see a best of 13.0 without tires. Right now you are probably making 325 or so without headers.

60' 2.280
1/8 9.110 81.72 mph
Et 1/4 13.852
104.55 mph

Was having problems with the hydrolics where it didn't let me go into gear at redline so I couldn't jam it into gear like I wanted to this was my first pass the 4 after it kept missing 3rd felt like it was inbetween 3/4 wierd. Clean fluid and a 5.0 shifter

heres my 2nd best where i missed 4th and hit the brakes to try not to run 13s with no helmet
60' 2.251
1/8 9.004 82.42 mph
1/4 13.957
89.05mph

if i didnt miss 4th in that run i bet that would of been the best run

Just practice more. The 60' is killing you. Tires and getting that clutch issue worked out will go a long way.

Yeah my buddy says i need to get a TickMaster cylinder, thatll probably be my next mod then qtp headers with ory
