Turbo Launch...

proxrsledhead · 08-01-2008, 01:57 AM

So.. this doesn't regard you lightning guys so much.. but you guys may have some knowledge that I need. I have a 97 F150... if ya didn't know already I build a "mid mount" turbo for it. I've been messing around more with launches in 4wheel drive, and I must say.. it' feels quite nice--Breaks all 4 loose launching at 9psi, not really any wheel hop; I loveee my torsion bars =).

Anyways... I have the ****ty electronic shift on the fly Tcase... with vacuum hubs. Anyone know any tricks that I could use to pop it out of 4wheel after I launch? Maybe a few of you know that parish guy that had the blue silverado.. he did 4wd launches and shifted out to 2wd mid run If I'm not mistaken.

to keep down on wheel spin you're gonna have to lower the front of the truck. Un crank the torsion bars. You are getting to much weight transfer. Back tires are spinning with no weight on the fronts so they spin also. Lowering will also get rid of some of the bumpsteer from the front wheels loading and unloading.

Paul parrish has a straight axle out of an older chevrolet and has changed his transfer case out for an old one i do not think ford can shift on the fly like that but i will check it out for you and get back with you later today

You can come in/out of 4 high on the fly but not low.
