This is rough but usually pretty close. Maybe a little higher for a turbo and a little lower for a blower. Seems like the first few psi are higher, the it is consistent for awhile. Then at some point your compressor runs out and the hp per psi drops off hard.
I just did the math for mine using rwhp and it is saying that I am trying to add 406 rwhp with my setup. No wonder I am having fueling issues, lol.
