It was a stage 1 garrett powermax turbo, its a direct replacement for the hx 35 on the dodge 6bt but will support up to 645 horsepower for the stage 3 version, spools like a supercharger and they are bulletproof. Plus the dodge powermax can be WATER COOLED :)

Yea theyll fit on a 4bt but they are $$$$$$$.
When they say 645hp, are they talking petrol hp or diesel?
10 petrol hp worth of air is about 1 lb/min of air.
On diesels it's completely ambiguous.
