Back to 4wd launching I go....I did it a few times awhile ago but figured my days would be numbered if I continued. Glad to hear it can take the abuse.

F8L Z71

I ran N/A for a year with the cam and bolt-ons in the low 14s and never had an issue. I beat the hell out of it launching after the turbo install and it never even whimpered. The only issue is in high TQ applicaitons (600+ft.lbs.) you will have to crank the torsion bars down a bit when racing because the front end will come up off the ground things start gettin hyphy real quick.

I am now doing a swap on the Z71 to an 80E and HD T-Case so I 'll never know the stock limits to the 1500 T-Case.

coool my angle is about the same as urs hehe, what so when you do the 4wd launchs do you do them in auto 4wd or just plain 4hi

F8L Z71

In high TQ combos you have to use 4HI.. Auto 4WD makes weird noises and shudders ALOT once you start making serious HP and a big stall.

Do you see any problem with shifting out of 4wd as soon as I start moving? I don't wanna run in 4 hi all the way up into the 90's.

F8L Z71

Nope. I used to shift out of 4wd once I started moving and it was fine. After the turbo though it wouldn't shift out so I run 4wd through the whole 1/4.
