42 pound injectors enough?
I currently have them on the car. I am thinking about upping the boost (vortech v-2) and the car will be putting down close to 600RWHP. I am also getting the Kenny Bell BAP and a Walbro 255LPH fuel pump to go with it! Thanks for the help!

42PPH inj's are rated at 3 bars, [43.5psi]. If you run them at 60PSI, then the rate is 49.6PPH.
The math for fuel required at 600RW, [using 680 FW],
indicates the injectors, at 90% DC, are going to have to be in the 56/60PPH range.[actual calc is 56.6PPH]
A 60PPH, will fill the bill, and give you a bit left over....

If you want some margin for error and a little overhead, go with 60# injectors.

I wasn't able to get away with 42 # injectors at 600 rwhp. The 42's worked great on the 500-520 rwhp ProCharger setup, but I had to upgrade with the turbos. The 60 # Mototrons work great.
If I had to do it over again I would start with the Mototrons. Buying the same parts over and over gets old.
