I'm not to sure on a centrifugal supercharger the roots type on the Lightning takes 65-67 HP to turn. So in other words a stock 5.4L puts out 260 HP a supercharged lightning puts out 360, so the supercharger has a net HP rating of 100 and a gross HP rating of about 165 HP. In theory a centrifugal supercharger would require less HP to turn than a roots type. I believe I've heard about 10-20, but don't quote me on that one. It would be nice to have a centrifugal supercharger that has a varying speed pulley (a cone that moves as RPM changes, similar to a snowmobile) maybe this would allow superchargers to have move boost at lower RPM's. Wait a minute, did I just give up a million dollar idea?

Chuck,
Since ya-da-man for engineering, especially the FERD mighty 'FRIGHTENING',
how much will the ATI SC take in HP rating to power the unit or in another
words how much is lost to the super charger operation?
