I know that AFRs are just 1 key to the puzzle. I blew up a 600hp 2jz with perfect A/R due to lack of timing retard.
May I ask what horspower numbers you were running at 8psi?
Also, in your experience, what caused the grenaded motors in the examples you mentioned? Lean condition? timing? Detonation? Or rod/piston failure?
At what horsepower level?
As I mentioned, I am going to use slightly larger injectors at 80% duty cycle to decrease fuel pressure and keep that margin of safety and meth injection to control detonation....and a larger turbo to decrease air temperatures at that flow. Obviously 8psi on a t72 generates less heat than 15psi on a td04. Hence my question, at what point did 250cc injectors hit 100% duty cycle. With that info, I can reverse calculate fuel requirements with FMU and larger injectors (theoretically...). thanks for you help
