What do you want for comparing supercharger ports? Equal levels of boost or equal pulleys (external)?
Rotor speed should be the exact same on both (someone pointed that out to me)
or
at least boost for boost worse case scenario
boost for boost is the only way to get any useful info. and i really wanna see how it turns out so i can decide which i want to go with!
Just so you guys know, boost is not the best factor to judge performance by. You want to match rotor speed. Boost itself is a factor in the output performance of the blowers, taking it out of the equation gives unfair assistance to the weaker port.
