Hey Inferno, I just read your signature. I think the hope that your car will be a supercharged stang contender when you add your turbo and other goodies is a bit of a reach.
I've run supercharged Mustangs; two of'em to be exact. The Saleen and I were a dead heat. The '88 pulled away from me. I'm not bashin' your car, but a supercharged Mustang is a big bite to swallow.
