An FPR is not a good purchase at this point. It will be when you start making more power than your injectors can support.
19# injectors at 39psi can support about 270 hp at 90% duty cycle. This is based on .5 #s of fuel per horsepower per hour. Some engined do better and some do worse. .5 # is a good average. exgmguy, how did you go about tuning your fuel pressure on the dyno? Did you set your pressure, drive around for a few days and then go to the dyno, or did you set your pressure at the dyno between runs? ------------------ 351W 89 Mustang GT Convertible |
