The world's first N55 HPFP upgrades from Dorch! This is a complete plug-and-play kit to realize up to 530 HP (Stage1) and 650 HP (Stage2) on E10 fuel. No cutting, no bending, no crimping, etc. This kit is directly installed with full control by the DME, just like the OEM pump. All the safety and sophistication of the stock DME is retained.

N55 HPFP Flow Capacities:
The following table is provided as a reference for maximum fuel flow in cubic inches per camshaft revolution for various B58 fuel pump options. These calculations are based on the N55 camshaft. Depending on the lift and number of cams on the camshaft, each engine will have different fuel flow rates.

Pump Model Fuel Flow (cc/rev)
HDP5 (stock N55): 0.837
HDP6 (stock B58TU): 1.178
Dorch Engineering Stage 1: 1.221
Dorch Engineering Stage 2: 1.465
