STS turbo vs. roush supercharger

[NITEMARE07]

I guess what I'm trying to get to is which would produce more hp/tq? I've seen that the superchargers will put out on average 100 extra hp. Didnt know if anyone else on this forum has went the turbo route. If i went with turbo i would need two since i have true dual exhaust.

only 100hp? Would like to know what garbage supercharger that is... the whipple will do roughly 60% increase in hp

To answer in short without going into detail, which will give more hp? Turbo hands down

Turbos tend to be more efficient in terms of output vs parasitic loss. Outside of that...

Turbocharger advantages:
Less expensive
Easier to maintain
Boost level controllable by wastegate

Supercharger advantages:
Linear power output
Easy to install

If I were to choose, I'd go turbo even though the systems are a little more complex. However, since you're running full duals it might be cost prohibitive to try to run a twin turbo setup. That's up to you, though.

Good luck with your decision.

So how much boost would be too much for a stock motor with twin turbo? I'm thinking somewhere in the neighborhood of 8 pounds. I like the idea of turbo because most guys run superchargers and of coarse that unmistakable whistle they produce. So even though superchargers put out 60% extra hp, turbos provide more! That would be some serious muscle.
