Hey y'all I need some help.

Is there a rule of thumb for working out how much extra HP/TQ you get from bumping compression a certain amount?

I am looking for something like the rule that states assuming no parasitic losses on a FI engine, boosted Hp/TQ is aproximately = to na power X [(boost psi+16)/16]... i.e. if you have a 100 hp na motor and put 8 psi boost to it, assuming no parasitic losses hp will be 150 ... 100 X [(8+16)/16] = 100 X (24/16)= 100 X 1.5= 150.

Is there a similar rule for compression?

General rule for years has been 40 hp per 1.0 raise. Taking in certain considerations. If you have a decent cam and matching comonents and go from 10.0 to 11.0 it is almost always 35-40
