[QUOTE]Originally posted by 93PONY: [QB] RPM has nothing to do with fuel requirements??? LOL Riiiight. So an injectors pulse-width at 6000rpm can be as long as when the motor is running at 1000rpm. Riiiight. Max pulse-width for ANY injector at 1000rpm can be 6 times what it can be at 6000rpm. I do think this plays a factor in selecting the correct fuel system. RPM directly affects max pulse-width of an injector. Choose too small of an injector & you will go lean at high RPM's where the injector is basically open 100% of the time, but still not keeping up with the demand for fuel. Sure...an easy way to band-aid this is to add fuel pressure, but then the demand for more pump increases. [/QB][/QUOTE]
