After much hot-rodding '70's american muscle, I found the best HP bang per buck was a roots type straight rotor (2 lobe) supercharger (like the small B&M or weiand)... the next best was a centrifugal charger (like Paxton). The paxton has to run at atmospheric presure on the inlet, it would seem this would lend itself quite well to huffing a D. Mounting the compressor is a bit like mounting a big alternator. The belt is normaly a 6 or 8 rib serpentine. (the only real problem comes here, mounting the pulley to the crank, and isolating from the high temp of the exhaust.) None of the turbo's lag, spool-down, oil coking problems, or high under-hood temps... a 40% gain over normaly asperated stock motor, and nothing internal need be done on the motor, at least for low manifold presures. I don't see why stock intake, and injection wouldn't be fine for 3-5 lbs.
