Exergy Performance 10CP3 10mm Stroker Modified CP3 Fuel Injection Pump If you are looking for the most aggressive flowing single CP3 pump on the planet than the Exergys line of stroker CP3 pumps are for you. Exergy's 10mm stroker CP3 pump will flow more fuel volume than any other CP3 pump currently on the market! At the factory drop off RPM level this pump is flowing nearly 81% more volume than your stock CP3 pump. These pumps will flow more fuel volume (L/min) from idle all the way through the working RPM band, and then some at the same linear curve without any drop-off. The 10mm stroker CP3 utilizes a unmodified regulator so this is virtually a drop in replacement without need for Mprop table tuning adjustments. This pump will support 800+ horsepower by itself without the need to a secondary pump!
