There was a guy on our "old" forum with a Vortech on a V6 that made around 275 to the tires.

I'm not trying to sound like an asshole or anything, but honestly you'd be better off selling it and buying a V8 car if you're trying to make it perform better. For the money you'd spend getting it up to stock V8 power you could sell it, buy a V8 car, and put a little into basic bolt-ons. Just my $0.02.
