yeah, they do produce less heat. they don't take up nearly as much room and are easire to install. a roots or screw produce more stress on the engine. and they only produce their peak psi mid-way where as a centrifugal stays with the rpm band.

 

Umm... Danny (or was that Adam?) never built a twin charged Z31. And he sold that car a few years ago for much less than it was worth.

 

Im wanting to be different and supercharge my 88, but i want to bore the vg30 30 over so it becomes a 3.3L. But i had another idea, the xterra has a supercharged 3.3L from the factory right? so can i take that motor and bor it to a 3.6L and beef it up with a bigger supercharger. Im looking to make it a show/street car with roughly 600-650hp.

 

A VG block can't be bored that far, the safest you can bore a vg33 is to 3.5 and even that is a stretch.

You have a LOT of reading to do if your asking questions like this and want that much power. You will pretty much need a built motor with ALOT of custom work, even more so with a supercharger.

 

Go for it. Let us know how that works out for you.
