Neither would I. But 480+ is pretty accurate when describing their setup at "nearly 500," which is what JDM has actually done with their Saleen combo. I know they haven't updated their website but they are active participants on another forum I frequent and their numbers are really impressive.

Also, the Saleen is a roots style S/C, while the Kenne Bell is twin screw. The Saleen makes up for its tendency to produce more heat by including an intercooler with the kit, but the intercooler takes energy from the engine, and also it weighs more.

:notnice: Saleen series VI (for the 2005+) is a twin screw. All superchargers produce heat. It is really a matter of how much heat is tolerable. I, personally, would rather have an intercooler, no matter what brand S/C I ran. The extra weight normally is negligible in comparison to the ability to run at higher boost levels creating more HP.
