BDs High Performance CP3 (HPCP3) Injection Pump with up to a 72% increase in capacity / displacement delivers enough fuel to support up to 700hp while maintaining 24,000psi of rail pressure. The HPCP3 pump replaces the existing injection pump and simply bolts in place to produce up to 5.25 LPM versus the stock 3.05 LPM. Thats right, all that fuel without going to a dual pump system _ no extra pulleys, belts or pumps to install. BDs HPCP3 pumps are engineered with an enhanced metering unit and new design cam shaft with modified plungers and stroke. Plus, the HPCPS eliminates the off throttle fuel spikes common with stock pumps that can potentially damage injector nozzle tips when trying to produce more than 500hp. All of these modifications deliver long-term durability with consistent high fuel pressure supply on demand that provides efficient atomization resulting in more power, better combustion and lower EGTs. Designed for street, towing and race track applications, each HPCP3 injection pump is fully tested before leaving our facility.
