Procharger P1SC Setup

I really only have one question right now, would using the stock gear box be a bad idea?
It has a 4.1 gear reduction so you should only have to spin the input gear about 15k rpm to get the max rpm out of the impeller wheel. The only issue I would see is a motor with enough torque at 15k rpm to spin the gears.

Depends on whether you can get a motor/esc combination to run at that rpms with enough power to do the job. Allowing for the extra 10% or so power loss through the gearbox. The reason the P2 is what so many of us use is because it excels in the rpm ranges that suit readily available hobby motors without the need for an expensive gearbox (that requires additional power to drive through it).

Prochargers generally require more impeller rpm than Vortechs. But it becomes a trade off (like most things). With higher rpm electric motors, you can get the same total power output with smaller motors at high rpm, but eventually you start incurring more switching losses at high rpm. You'd need a pretty beastly motor to hit max impeller rpm at any boost level. In fact, I'm not sure you'd be able to with any available motor. A lot will depend on where you end up in the compressor map. For example, running it wide open (i.e. into choke), you'd probably need 70-80 hp; but running it at max impeller rpm in the sweet spot of the compressor map (at that rpm), you might only need 40-50 hp. Honestly, I think it's best to shoot for a lower impeller rpm and be in the highest efficiency zone of the compressor.
