N55 Stage 1 HPFP Upgrade - Dorch Engineering

This is a complete plug-and-play kit to support up to 530whp on E10 fuel (this number can vary quite a bit depending on tuning strategy and the blend of ethanol). There’s no cutting, no bending, no crimping, etc. This kit drops right in with full control from the DME, just like the OEM pump. All of the safety and sophistication of the stock DME remain in place. N55 HPFP Flow CapacitiesThe table below serves as a reference for maximum fuel flow in cubic centimeters per camshaft revolution for various N55 fuel pump options.
