For the money it takes to get the sytem up and running, a turbo will give much more reweard. Like was said..They are a huge drag on an engine. Go grab even a P1SC and turn it by hand. That 2300hp blower I'd bet tkaeas at least 400hp to drive it at max boost. A smaller turboe, priced I'd bet fairly close to that blower's price, will make the same 2300, but not draw any. You could match the boost curve of that blower with a turbo, and make close to 3K hp. Ask how much 3-400hp at that level will cost to get...But it means you need custom manifolding. But when the engien is $50K, what's another thousand?
