AP1 (2.0L, 9000 RPM) should not use smaller than 3.4", AP2 (2.2L, 8000 RPM) should not use smaller than 3.0".

Its their miscalculation is what it is. Based on maximum blower speed efficiency.

To prevent overspinning the blower.

Not to thread jack but I'm lost on the boost. There's guys out there making 15psi plus up into 20 lbs but they're listing 12 lbs as the highest. Is it because the 1000 comptech blower that the pulleys are for?
