go to streetflights website and look at the dyno graphs for both of them. I have owned both and I can tell you that they have two extremely different feels. I'm waiting on tuning before I can give a full report on the turbo. But I did love the S/C but the Turbo just seems to have so much more way low, even before the boost. I think I'm gonna like the turbo better.

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. . .

It boils down to this.

Turbo equals power everywhere.

S/C equals power above 4500rpm.


Turbo equals massive torque everywhere.

S/C equals good torque above 5000rpm.


Turbo is more efficient everywhere.

Turbo does not require high rpm to make high HP.

S/C can make good HP below 7k but the cost outlay is tremendous. (right Rick )



Mod for mod a turbo is actually cheaper. This considering a S/C (3700) NEEDs the shaft bearing & intercooler (nearly 2k) to be remotely reliable. Then tuning and fuel upgrades (600ish)

Add in headers and that's $7000 and still no where near the power curve of the turbo kit.

Just wanted to point out, all bench racing/numbers aside ANY FI set-up is a lot of fun. Until you feel over 300hp in these cars its hard to say anything is inferior no matter how its generated.
