Mazda Comp had a 13b PP N/A putting down 305hp, with a Bosh mecanical injection.
Based on the multiple test we did on the dyno, I could get more HP if I went with a dry sump system.
Right now I 'm going over 9000 rpm, with a dry sump I could push to 10 or10500 rpm and should get aroung 290hp at the wheel.
My freind run a peripheral port with a 55mm carb and dry sump, and he gets 275hp at the wheel.
PP can be tune in a multiple way, awrracing.com got a 20hp gaine at the wheel by trying over 20 combinations of header and exhaust.
My car has more to go for sure due to the fact that I have a bad exhaust system.
If I had time and money I could gain more HP just be making a new exhaust system in 3.5inches not 3 inches, and ashorter header as well as a shorter intake.

last point.
Do not forget that I'm running road races, so I need a low range to high range of HP, and I'm running endurance race from 3 to 6 hours.
I will bet any body with a fat wallet, that I can get 300hp at the wheel, if I did not care about blowing my engine after a 1/4 mile.
Also timing does help a lot on hp, and I was conservative in my timing no more than 20 degres.
