Okay, are you generalizing, or talking specifically about the S2000, as I was?Originally Posted by bubbrubb
I have never seen any documentation that says superchargerd are somehow limited to 45-60hp. You can add a zero to that number on some drag cars. It's usually a percentage of base HP, roughly 45%. So, yes, on a Civic base 1.5L engine, you'd be lucky to see 45hp.
By the way, the magical supercharger I was talking about goes by the name of Comptech. They bolted on a supercharger, which brought an S2000 from ~205 WHP (240 at crank) to 289 WHP. That's 84.
If you need proof, try Vortech's Site
They show power gains for a variety of vehicles, from Mustangs and Camaros to Civics and Integras. They show a crank HP increase of over 100 for the S2000.
As for the ULEV, that accounts for some of it, but a lot of it has to do with design. For example, to get the kind of power out of the S2000, Honda needed 11.0:1 compression, thus adding high boost means lowering compression, which means more money. For the most part, modded S2k's seem to run in the high 200's, not much better than modded Integras and Civics. One of my customers at work took a low-tech OHV 2.2 Cavalier and got 220hp without boost or juice. He's planning on slapping on a turbo and hitting the 300hp mark. I won't even go into the Toyota and Nissan 6 cyl's. 600hp without touching the inside of the engine.
Anyway, in the end, it all boils down to the ever-powerful dollar.
