Dorch Lift Kit - HPFP Upgrade - PWG BMW 135i/335i/X1 N55

We are proud to offer a game-changing product for the N55 community! With this innovative solution we are able to add up to 49% MORE fuel flow on top of either one of our existing N55 kits. This means higher power capacity than ever before possible with the OEM direct-injection fuel system. We start with Genuine BMW vacuum pump cores and install our Dorch Engineering Cam within the OEM assembly using our proprietary manufacturing tooling and validation equipment. What you end up with is a ton more fuel flow in a very simple and clean package, all while utilizing the safety and sophistication of the stock DME.

N55 HPFP Flow Capacities

The table below serves as a reference for maximum fuel flow in cubic centimeters per camshaft revolution for various N55 fuel pump options. These calculations are based on the stock N55 cam lobe unless otherwise noted (Lift Kit).

Pump Model Fuel Flow (cc/rev) Fuel Flow w/ Dorch Lift Kit (cc/rev) HDP5 (Stock N55) 0.837 NOT COMPATIBLE HDP5 Evo (Stock B58) 0.897 NOT COMPATIBLE HDP6 (Stock B58TU) 1.107 NOT COMPATIBLE Dorch Engineering Stage 1 1.221 1.818 Dorch Engineering Stage 2 1.465 2.181

This fuel flow equates to never before seen DI power numbers! When combined with larger injectors and our Stage 1 pump, this product will support 750whp on E10 and 600whp on E85. When combined with larger injectors and our Stage 2 pump, this product will support 900whp on E10 and 750whp on E85.

Software changes are required to run this upgrade, but we do have preset optimized maps available via Bootmod3 and MHD (coming soon). Simply check the box for the appropriate “Lift Kit” upgrade when flashing.

NOTE: When pushing much beyond the flow capacity of our existing Stage 2 HPFP kit, the N55 is very much limited by the injectors. In order to see the full potential of this upgrade, it is highly recommended to upgrade to the larger S63 EU5 Injectors.
