Launching ??

I will be going to the track next wednesday and I have a few questions...

1. Do i launch in 4wd? I thought that the 4wd is only good up to a certain speed?

2. I have heard to launch at or around 10psi? Correct?

Any help would help.

Thanks!

don't watch your boost.. just bring it up to around 2,000 rpms for your 6.0 and let her eat.

Mess with tire pressures and varying rpm by 1-200 rpms since you have larger tires. Do you have anything to keep the axle in place? If not be careful, you can break sh!t real fast on oversized tires!

Not that I know of. I bought the truck 2 weeks ago, so I am not sure of exactally whats on it.

I dont plan on making too many runs next wednesday, I just want to see what it can do. I am towing up my buddies 04 mach 1 that should easily dip into the 12's. So we shall see...

Any other advise on launching? 4wd? or 2wd?

With my dodges I would launch in 4wd and shift to 2wd around 45mph...it worked pretty well to help keep spinning the tires down..

with these trucks it shifts out of 4 wheel..

do what marty said and bring it up to about 2000 rpm..with 37s they should hook pretty good. if he jumps around then lower your rpm to like 17/1800

after the run just switch it to 2 wheel. i have brought my truck to 108 mph in 4wheel. from what i was told it switches itself out of 4wheel at a certain speed.

just have fun and play with the truck a little bit. dont go crazy trying to launch it, practice on the street to get a feel for it. just switch to 4wheel and bring the Rs up a little bit and then switch over, you will feel it pull real good. let us know how you make out
