Less restriction on the air being pushed out from the rotors, so...more common sense.

I didn't say it flows "more" I said it flows "better"...more efficiently than a stock unit. There wouldn't be anymore turning or more "cost of power" because the pulley size isn't changing. So, adding more common sense.

Sure, but then you're back to square one with the heat and innefficiency issues. And if the car knocks (OH HEY, ALL STOCK CARS DO THAT...wheeeeeeeeeeeeeeeeee), and you reduce flow...like when you install headers...because psi levels drop then as well...and the car DOESN'T knock, then you actually have a performance increase from the fact the PCM isn't yanking timing out.

See above. Blower only spins faster or uses more power if you're dropping pulley sizes. I'm talking about keeping it stock. BREEEH.

I can think of a few ways to make a blower test bench. The only issue would be it would only be relative, not absolute. But thats like any dyno or flow bench in the history of cars.

Didn't reply, because common sense.
