dsm 450cc injectors!
How much HP can DSM 450cc injector handle before I will have to upgrade to 550cc injectors? Anyone in the high 3's low 400?

I wouldnt go more than 300-325hp with 450's. Im sure you could raise fuel pressure but the duty cycle would be too high.

How can the duty cycle be ABOVE 100%??? If the injectors are open 100%, then they are open 100%. Please explain your statement. Did you mean just UNDER 100%, like 99%? I thought DSM's needed at least 10% duty cycle for opening and closing time.
Curious.
