12.4 @ 115?

so i just ran my car at the track for the first time and my best time was 12.4 @ 115 with a 2.0 60'. my mods are exhuast predetor programer and a shifter. i ran this time on kuhmo exsta mx's wich are just a street radial. i just wanted to know if this sounds like where i should be running? should i be satisfied or should i have ran a better time?

With a 2.0 60', I'd have guessed a 12.3 at 116, but I think you are about right where you should be. I can't get any better than a 2.1 60' with my stock F1's.

You're very close to where you should be.

What we're the air/coolant temps during that run? Shift points? Launch rpm?

I blasted a 12.25@117 the other night on a stone cold stock engine.(04 Z) Air temp was 40 deg's. I also dropped the rear tire pressure to 20 and did a small burnout(Per Rangers suggestion) as well as overinflating the fronts.

Shift JEEEUST before the limiter on all gear changes. That is the hot ticket to quick times.

I obtained a 1.99 short, slipping the clutch and definitely not on an optimum surface(Wednesday nights have a lot of rice etc). I'm sure with more practice I could improve it. An "11" as it is?

Maybe Ranger could do it seeing He has the ability....but your car definitely has more in it. Thanks for the kind words on my run

Either the clutch got stuck or I did not lift my foot all the off, but this was in 1-2 2-3 and 3-4...so I am thinking the clutch got stuck....car was smoking all the way...nasty smell...thought my day wasover.
