Aerochargers are better than a twin screw!! hahaha ;-)

It's still the most efficient (next to NO2) HP you can bolt onto an
engine--and it's using gasses that would
normally be expelled as waste--can a belt driven blower compare ? I'll
rephrase what I said--"You're
getting something as close as possible to "free" as you can get".

>snip<

You can take a 15 lb turbo and make 100+HP--you can't do that with a belt
driven blower
lb for lb. Further more, if it's taking 30 PSI to drive a turbo to make 15
PSI, it's not really that efficient, and
you've gotta do some more housing work. At no point in any turbo charger
design manual is exhaust
backpressure mentioned as a detrimental thing, unless parts are missmatched
or a high overlap cam
shaft is used. Backpressure is always at its worst in a 90 degree
crankshaft, and not a real issue in a 4 cyl.
