Smallest Pulley P1SC Stage ll

[whatsup62]

They are decent right up to the redline.

However over the redline ya, then the temp goes up.
So even if a person makes 1-2 more psi, they will gain nothing at the track.
Since the power is lost due to drive power, and temp.

Hence why I always shake my head at guys "over spinning" blowers.
And bragging about boost numbers.

If your car goes 144mph at 13psi
And 144mph at 15psi

Well, stick with the 13 ;)

Thanks for the info...so with the info you put in my other post on the crank pulley diameter...it looks like at 7500 rpm the P1SC-1 will be at 64894...being maxed at 65000...hmm..think I will shift at 7200.

Shift according to powerband, that’s the real benefit of these cars, RPM. Then adjust blower pulley to accommodate to shift RPM.
