Fleece Performance Duramax 10mm stroker CP3 is a straight
forward, no inflated numbers, CP3 upgrade proven to support
750 RWHP with the proper complimenting modifications. Not
only will it support 750 RWHP, but it also eliminates the
factory fuel flow restiction that begins at 3,000 RPM. If
you have a stock CP3 pump you are losing fuel flow and rail
pressure after 3000 RPM, which correlates to lost horsepower
when you need it most. This cost effective upgrade will allow
you to maintain desired fuel rail pressure through your entire
RPM range, as well as provide enough fuel to support 750rwhp.
Fleece Performance CP3 is tested on our in-house engine similuator
and pump test stand to simulate real world situations and
ensure that each pump is ready to work for you!
The fuel pressure regulator will need to be scaled appropriately
