Re: whats better

What do you want?

Twin Screw(positive displacement) has pretty much instant boost as soon as you press throttle

Centrifugal supercharger builds boost linearly, 2000rpm=2 psi, 4000rpm = 4psi, 5000rpm=6psi, etc. (numbers are just purely fictional for example purposes :p)

Turbo builds boost exponentially, 2000rpm = 1psi, 3000rpm = 4psi, 5000rpm = 8psi, 6000rpm= OVER 9000psi



twin screw just for the sound it makes

dont forget, you can build boost off the line with a turbo- cant with a centri, as far as I know

Can't he put a Cobra supercharger and heads on his GT. I think they are like 4000 brand new. And continue to work on it and build his way to 500 hp

They make a 2 valve intake for the GT's, but for as much as it cost to do it you'd be better off doing a KB or Wipple.

Re: whats better

centrifugal would be better for daily driving because you will stay out of boost most of the time. twin screw is torquer and boosts through the while RPM range
