4x4 launch
Hey guys I'm gunna be takin my truck to the track soon. I'm just wondering what a good boost psi is good to launch at with a stock input and in 4 wheel. Is it safe to run in 4 wheel all the way down the track?? Thanks y'all

10psi tops.
Yes. Just shift out of 4wd before you turn off the track. ;) |
I never went above 4psi but I'm sure you can go a little higher but not for too long.
|
I use to launch in the 12 psi range no problem
|
25psi can break stock shafts.
Just say'in. :w2: |
Thanks for the replies. Yeah I won't be goin anywhere close to 25 haha. I was thinkin about livin at the 10psi. I won't be runnin my 35s I'll be runnin a 285/65/18

I did a 10psi in 2wd and snapped the shaft shifting into second (first time I broke it)...I wouldn't do it w/o a billett input/flexplate combo, especially at a track...VHT is mighty sticky!:pca1:
