get some better tires, then you will cut some faster times.

I think at 17 psi on that turbo it should be really low 13's to mid 12's.

But still, glad you had fun

on the last run I let off due to fan shroud breaking lose, might have been a lower 13 there. Yea with better tires and some dyno tuning should do much better. This is the first time I have drag raced the car since I have had this turbo and clutch. I need practice, bogging between shifts and not taking off hard enough. was trying to drive it just like ct26, needs a few more rpms for a better launch

Looks like some tuning will do you a lot of good. I ran a 13.3 at 109mph with my SP61GT un-tuned running 17psi. Then I ran 12.99 at 112mph with a tune at about 20-21psi. Then I removed my CAT and and ran 12.5-12.6's at 116mph then eventually a 12.4 at 119 at 24psi (with my cylinder head lifting). So my point is, with more tuning and track time, you will see 12's soon enough with that turbo. Good luck.

The temperature gauge went past H on the 24psi run. I latter did a headgasket test and found lots of coolant escaping through my exhaust. The head was warped but the metal headgasket was fine.

that last pass sounds just like mine. I ran a 13.5 @ 100 with a 1.90 60' time on my nitto street tires. That was at 12 psi. The short time was there but once I got up top my wideband went straight to 10, rich as hell. I've since turned up the boost to 16 psi and street tuned a bit, but haven't been able to hit the track yet. Keep up the good work and get that 60' down!
