Me and my friend (the one I sold my old Dinan Turbo to) put our cars on the roller.
Fuel is RON98 (US AKI 93OCT).
GP500: 17psi, 5th gear
Dinan Turbo: 17psi, 4th gear (because 5th showed slightly less due to heat).
With GP500, there are some 2psi of headroom (that I tested last summer) left in the octane and fuel pump. Because for my daily and track map, I want consistent power.
Dinan turbo is pretty much octane limited, running 17+psi under max 95F of IAT that we saw.
Feel free to ask anything.
