Full Force Reman Stage 1.5 Injector Set
1994-2003 7.3L Ford Powerstroke
160cc and 30% nozzles or 180cc and 30% nozzles
180cc is the best choice for most OBS trucks. The only time we recommend the 160cc injectors is in high altitude locations or for the customer that doesn’t want a large power increase. The only benefit of the 160cc is that a completely stock OBS truck will see large gains without needed (recommended) exhaust or intake modifications. The stock injectors have an effective flow rate of 90cc.
The difference in stage 1.5 are the 30% over larger nozzles. The 30% nozzle allows more fuel to exit the injector quicker into the combustion cycle which increases horsepower even further. The injector has a limited time to inject fuel into the cylinder for the combustion cycle. We measure this time in milliseconds. With a larger nozzle, we can inject more fuel per millisecond into the cylinder for combustion, which creates more power. The downside to a larger nozzle is the extra fuel creates more heat and black smoke. So the larger the nozzle the more EGT’s are created and the need for more air upgrades are needed.
