Tai,

the twin screw auto-rotor supercharger (KenneBell) does not boost the motor during cruising, which helps maintain the good fuel economy of a motor, and will assist longevity as you have proposed. However, mash the gas pedal and FULL boost is provided in less than 1/2 second at any rpm, no spooling up like a turbo charger or centrifugal supercharger. The auto-rotor supercharger is used by Mercedes on it's various supercharged autos, and on the Ford GT40. The blower itself is very reliable, and the only recommended maintenance is an oil change every 12,000 miles.

I like turbos too, they are very efficient at what they do, but in recommending a forced induction system I must consider the use of the vehicle. On a race track where rpm's are kept up and traction is pushed to the limit, a turbo is a good choice. On the street, my recommendation is the KenneBell auto-rotor supercharger. You can drive daily in the Clark Kent mode and have superman available when needed.

Phil, your link supports my personal choice of a stroked 393 Cleveland using stock heads (some porting) and a high lift hydraulic roller cam.

I have mentioned Michael Menolascino's motor on the PIBB in the past. He's making 758 bhp at 7300 rpm with at 422 cubic inch Clevor. His cam is lifting the intake valves 0.795" according to the article in PI magazine, and the motor's compression ratio is set at 14 to 1. So this is no street motor, and the valvetrain will not go too far between maintenance intervals! However, my point in brining up his motor was to point out that those are oem heads he's making that power with, the same heads found on most Panteras. That potential is lurking within every 351C found in a Pantera. Back off on the rpm, cam specs and compression ratio to achieve reliability & drive-ability, and you have a 383C with about 450 to 500 bhp.

your friend on the PIBB, George
