get a good clutch and launch at 7500-7800 rpms like I did. I pulled 2.1 60ft's on street tires consistantly. all you do is let the clutch out just till it begins to grab before the tree starts down. hold the e brake up with the button in so the car doesn't roll forward. at the last yellow drop the ebrake and keep the revs between 7500-7800 and ride the clutch till about 15-20mph then dump it and push the pedal to the floor.
