Bold items are simply to separate the math



I'm assuming a lot here as I don't have all your specs. So your roughly 630whp? I'll also assume you've got headers & full exhaust?

P1SC-1's max impeller (max efficiency) speed is 65k. It should also be a 4.1 gear (step-up) ratio. Your blower pulley roughly a 3.60? And crank pulley a 7.5.

So [I](Crank pulley size / Blower pulley size x step up ratio) x max rpm= 61.5k impeller speed @ 7,200rpm. So your around 95% the max efficiency.

To see that kind of power on a P1 I'm guessing the car is around 12-14psi. What kind of psi are you seeing?

So the p1 is pretty much maxed out at 630ish? Fuck.

Feel lucky that number was achieved. The P1 an entry level head unit and I've seen it implode on itself at 440rw.

Thats enough of this implode talk. I won't be able to sleep at night worrying about it.

Haha, sorry. You can ask Blownaltered about his P1sc expierence. Once he stops swearing like a sailor from the anger of it, I'm sure you will understand.
