depending on the setup, you'll see full boost at ~3k with a turbo (depending on the kit, trim, and tune, as well as the engine!!). You won't see full boost in a vortech until 6700rpms. So, if you look at Rick's dyno, his 500hp came around the end of the rpm range. . .that still doesn't mean it's wicked sick, because when he's tooling around town, he's probably pushing 3-4psi, not heating stuff up too much (esp with that custom intercooler!), and pushing 300-400hp. I'm stating at the crank numbers too. . .with the driveline losses factored in. . . .

If you are HELL bent on a supercharger, do for it, it'll COST THE SAME, because you'll have to buy an intercooler from Rick, as well as get the shaft reinforced. . .it depends on HOW you want the power given to you. . .

Remember, you won't be able to put down crazy numbers from a turbo kit on a stock CSVT 2.5L, with the piston problems mentioned in the 3L FAQ, you could probably get away with 5psi on a t28 kit on an '00 CSVT. . .so, looks like it's a question of how dedicated you are to burning a hole in your pocket. . .
