What is peak power that the stock fuel system can handle?

91RS

Not sure, but curious to know.

There are kleeman blower cars with stock fuel inj/fuel rail and FMU running 450+rwhp if that helps. Of course the FMU tricks the injectors into acting like bigger inj.

FMU? Increased Fuel Pressure?

Fuel management unit. You can increase the fuel pressure to get more fuel sprayed with each ms of duty. You then need some electronic trickery or adjust the stock ecu to reduce the duty cycle in low load areas of the fuel maps.

Gotcha...essentially keep the IDC around stock levels to keep it on the same timing curve...
