A small supercharger pushing 8 PSI = Very fast turbine speed. That means a very hot turbine. A hot turbine means hot air, and no Aftercooler/Intercooler was mentioned anywhere in this post. The supercharger would be running off what, one air filter? And where would that air filter be positioned exactly... A supercharger is supposed to give you high power at low to medium rpm and no lag. At slow speeds your air filter will be sucking in all the hot air from inside your engine bay, heating the air up even more on acceleration by the high speed turbine, directly into your engine... Until you reach a decent speed where cold air rushes through the grill into your air filter your will probably be getting some pretty lacking performance, possibly even worse than turbo lag... Now if somehow you can install that aftercooler/intercooler, and position the air filter in a decent spot somewhere in the front of the engine bay... Hey at least you have bragging rights that you have a supercharged Crossfire though eh?

But what do I know I'm just a kid.
