is it possible to set a two step up with an auto trans i wanna start boosting at the line my stall is 3600 not sure if its doable.. through a pretty much bullet proof 4l65e.. single turbo cammed 4.8 w/ some head work 76mm turbo @20psi just wanna get maybe 5-8 pounds at the line for a hard launch. i could use the signal wire on the brake switch instead of the clutch i just dont no how it would work or if would just push through the brakes.. truck is awd btw..

 

I think your going to have an issue pushing though the brakes with out a T brake. how hard can you push it on before it pushes with the brakes now?

 

What year truck? Hydro boost conversion is only way to go. I did that on my '04 silvy I had. Could launch 5-10# and never push through the brakes

i could build ~7psi on the footbrake and a 2 step @ 3500rpm 100% tps without pusing through the brakes, but my stall is probably a lot looser then yours.

 

Just depends on combo...mine makes 10 psi footbrake at 2800

 

It should blow through the converter if u have a trans brake wire it to that, thats how i have mine and it works fine

 

Hoping to do this as well. If not, I guess I will get a tbrake.
