Message I ran those at the track, and couldn't get under a 2.2 60 ft time. Do your tires spin badly at the top of first gear, and into second a little? I have the same engine mods as you (+ an UD pulley) and just finished off the Falkens, Those fk-451's were great in the rain, but don't compare at all to a better dry tire. I tried the Fuzion ZRi's, expecting to be dissappointed with them, but being happy they are cheap. Surprisingly they launch very well..I don't fry the tires under boost in first or second. Maybe just a little squeel under first gear pulls, but none of the tire destroying frenzy of wheelspin and wheelhop that I had with falkens. I even tried adjusting my suspension setup at the track with little difference. Basicaly better tires would help, but I ran 13 psi @ the Atlanta Dragway, and ran a 13.3 @ 107.4 in 80+ degree, high humidity weather...and I spun upon full throttle in first and second even when I was careful. Did this on my Falkens. I'm expecting the new tires alone to bring a 1/10 or more off my 60'. If you could get you 60 ft. time towards the 2.0 seconds range, you're trap speed indicates that the car should be capable of mid /high13's. Of course your car should be capable of high 12's with proper tires, so I would think that you either have a boost leak, or that something else is robbing you of power. Does the car idle smoothly (for a TTZ, anyway) How much vacuum do you draw when the car is warmed up and at idle?
