and 240SXer... how many psi were you running on the gt25? f150 ran almost a half sec better with his stock turbo and dr's. something doesn't seem right. you should be trapping 110+ and running mid 12s (at the very least). even if you were running about 14psi you should be in the 12s.
I'm not sure. I never wasted my time running regular tires at the track.. I bought a second set of stock alloys and mounted the bfgoodrich g-force drag radials. I run those on the street when I'm looking for trouble.
I would probably run a 13.5-13.8 on normal street tires, maybe. I cut a 1.79 on my drag radials last time at the track. the 1.84 was the first time at the new track with drag radials. When running with slicks i averaged 1.706 60 ft time. That was out of 6 runs.
Most average drivers will not be able to get a 13.0 or a 12 out of the stock turbo. It takes alot of practice. I have over 40 passes on the car.
