Sounds like they did some homework with the stage 3 kit. Water/meth inj on top of the stage 3 kit should make the intake cool to the touch. These SRT-4's got my attention in a big way. Where can I find a compresor map on the turbo used on the 3 kit? Just from reading the turbo sounds like a special gig integrated into the manifold.
So, what is the next step after the stage 3?
This SRT stuff is an interesting study.
