Procharger's specs say the P-1SC can handle up to 825 hp (I assume at the crank) and up to 30 psi.

Real world experiences from the shop I use says 600 rwhp and 18-20 psi is pushing that head unit. So I bought supporting mods (pump, injectors 3-core IC) to support up to 600 rwhp for when I do things like the topic of this post.

I say push 16-18 psi and see if you have the flow to max out the blower, I doubt it but you might get close and when you are not happy with the 500 rwhp neighborhood spray some go-juice in that thing and really make a statement.
