wow, quick responses, thanks. i did read through a few posts to get an idea of turbo vs super, blow-thru vs draw-thru, horsepower claims, etc. i get the part about blowing up the weak links. this winter i planned to do the bottom end - balancing, fasteners, cam, cam chain. i have an 8" rear going in and just finished the suspension and brakes, so it's getting ready for more HP. what i was really curious about was 'driveability' - hard starting, high temperatures, anything wierd about turbos or superchargers that made the car more tempermental or harder to drive daily (like a 300-degree cam would).
