Drag Strip

[assman]

Well ive gone to the track with all 3 of my last cars all more then twice, probably 10 times altogethor with about 140-160 1320' runs. So im no expert but I do have some pointers that will help.

As Clos561 and I and others have said:

PSI ~17-18
Drop Clutch < Slip Clutch but its harder on your car and easier to do
Shift no higher then 5500 or so becuase the power curve falls flat on its face
Depending on the track I cant tell you what to rev at but 2500 -3000 is typical.

Make sure you cool engine between runs. Do a small burnout to remove crud from tires any more and its just a waste of street tires.

Oh and turn up your stereo and keep your windows down

I thought dumping the clutch was way harder on a car then slipping it? Any thoughts? What do you guys do in 1st and 2nd gear? I bog 1st and spin the hell out of second, or spin both?

That's what he said. It's harder on the car, easier to do, but not as effective.

Run around 20 psi TCS/DSC off, launch at 3000 RPM, slip the clutch so you keep the tires chirping but not spinning (you're right at the limit of traction) without bogging. Shift around 5700 - 6000 RPM. Power shift from second to third. You should hit a good time.

Agreed, maybe I would of run better than 14.44 if I lowered my tires to 20 psi.. My 60ft was 2.17 on Normal psi with the stock street tires no mods.

Ok, even if I take off in first I still spin second no matter what. Do you get this too? I ran 14.8 in the high 90's missing 5th gear lol.

I think you need the driver mod.

my tires spin 2nd gear = no traction, u gota let it spin until its jsut right then shift to third. Thats my problem, the 2-3 . i shift early and the car goes to really low rpms...practice practice .(hand)(smash)

Learn throttle control. If you're spinning your way through 2nd gear it's not only wasting traction, it's likely leading you to shift early in the RPM range.

Remember when I said you want to be making tire noise without making tire spin? When you shift into second, don't just jump on the throttle. Get into it gradually, keeping the car at that fine line between grip and tire spin. Once you get into tire spin you're wasting grip, and you'll either have to wait it out OR come off throttle, neither of which are ideal situations for a drag strip.

You ever hear slow is smooth, smooth is fast before? Apply it to pedal control.

Go slow to be fast is the motto I've used, but same principle.

When I ran my 14.44 I revved the engine at the light up to redline (to hold boost) and when it was time and the tach needle was on it's way down I slipped the cluth right about 2900rpm and power-shifted into second (this happens really quick) I still burned out a little in first and second, 3rd and up were just fast lift shifts (I still didn't lift quite all the way) My 60ft was a good 2.17 Why I only trapped @ 94.6mph I don't know..
