1/4 Mile Times For Isf.

[Pantelis K]

Hi guys, last night we had a street meet and i took my ISF out for my first time on the track for the quarter mile. I have not done any mods to the car as of yet and was only running my street tires. I do have the Michelin Pilots on. The best time i ran was 13.2 at 110 Miles per hour. I am not sure how this compares to anyone else who has done the run and what changed can be made to improve. I did do 4 runs in total. 2 with the traction control on and 2 with it off. 13.2 and 13.3 with the traction control on and 13.4 and 13.5 with it off. I know i am new to this so any feedback or tips would be appreciated. I have the MY10 ISF. Thanks.

how did you launch your car?

best results are from TCS and VSC all off

Yes the first 2 races i did not turn off the TCS and VSC . I pulled it up to 2000-2500 RPM with the brake on and let go and did 13.2 and 13.3 respectively. For the last 2 races i turned off the VSC and TCS and pulled the RPM to 3000 then launching and did 13.4 and 13.5. I was surprised also that i did better with the traction control on. Surprisingly the Michelins stuck to the ground brilliantly. Other cars could not stop spinning. (Skylines, XR6 Turbos). The ISF was impressive but i was hoping to get around 12.9 to 13.0 if possible. It did whip a WRX and beat a modified HSV. Have you done any trials with your ISF and how did you go?

3000 rpm is too much

most of the guys lauch around 2K

anywhere between 1800-2200rpm depending on how much grip you have

with a good launch you should be in the mid to high 12's

Any recommendations for tyre pressures?

Does anyone have any recommendations for semi slick tyres and preferably what rim size will fit the ISF with what tyre?
