The high pressure fuel pump (HPFP) is a cam-driven fuel pump that provides over 1500psi to the direct injection fuel injectors in your engine. As performance modifications are often desired for the 2.0T FSI engines, more fuel is required to support the added horsepower from larger turbos, ECU tunes, and other power-increasing modifications. The IE HPFP works effectively to increase the output of the high pressure fuel system, by using a piston and cylinder that offers 50% more displacement than the factory unit. This combination offers fueling for nearly 600hp at 7500rpm with proper ECU tuning.
By increasing the bore of the cylinder, we were able to increase HPFP output by 50%. That makes our pump capable of near 600hp at 7500rpm. As you can see on the dyno chart to the right, the factory fuel pump is out of fuel much earlier than the IE HPFP. Although it is capable of over 350hp at 7000rpm, it does not provide nearly that much in the lower rpm range where most quicker-spooling setups see peak power numbers. This is a great upgrade for those looking to do a big turbo setup, or even max out the factory turbo at higher boost levels. Our pump will be perfectly calibrated with any ECU calibration which is tuned for a 9.8MM diameter HPFP piston, which is commonly available.
CONSISTENT DIAMETER PISTON
With rigorous testing behind this product, we have determined that a consistent diameter piston is absolutely necessary. Many other upgrade kits available use a piston that steps down to smaller diameter. They do this because it allows them to use the original seal and nut assembly. However, doing this means that less than 1/2 of the cylinder is guiding the pin at the top of the stroke. This greatly increases wear, leakage past the pin, and decreases stability of the pin riding in the cylinder. Additionally, using a stepped cylinder causes a pumping action on the bottom side of the piston, which pulses fluid against the shaft seal, increasing the possibility for leakage into the cam follower region. With our consistent diameter piston, as with factory design, there is no displacement change occurring on the bottom side of the piston, so there are no pressure pulses against the shaft seal.
This is the upgraded hardware to assemble into your factory fuel pump. Fuel pump not included.
