400rwhp off of a gt28 + 21psi? i went with the wrong combo, damn thats sick!!!!! how long can u boost at 21 psi?
lots of people i know went for strokerkits and gt28**, mainly for mountain runs. average is 350-360rwhp at 1.2 bar boost.
i was wondering, how does the car react to more rpm(of course building it for such)? ive been contemplating building my sr for about 1.2-1.4 bar boost and about 8-8.5k rpm. the usual stuff of course, but wondering how it stacks up to the stroker kits...
i figure its a little cheaper to get the car to rev up there compared to getting a decent stroker set up and wanted to know if its worth it.
