superchargers take more power to get going then turbos

He gave me his rumor of a twin turbo setup for the Mazdaspeed one. I should visit Zeil Motorsports and find out if its true sisnce they did the turbo Protoge. I would think a supercharger makes more sense, since it won't need an intercooler with low boost and it will help low end.



Anyhow Panspeed made a turbo RX-8 about a year ago! I beleive it's about 550PS and I posted a link for it on the RX-8 forum, so it can be done.
callaway did the protege, didnt they?

A good SC only takes 1/2 HP to turn. A good turbo doesn't require any.



But, in a car that already has pleny of HP and no torque I think a SC would make more sense. You can always change pulleys and run 10 or 11 lbs out of a SC if desired.. but I think 6 or 7 lbs on stock pulleys and 200 lb/ft of torque is a better idea.



This debate almost mirros the S2000 debate: SC or turbo? Hell the two cas even have almost identical power specs.

A turbo restricts exhaust gases somewhat while its being spooled up....
