Dorch Engineering N55 High-Flow Fueling Package — Up to +49% DI Fueling Gains

We’re proud to release a game-changing fueling solution for the BMW N55 platform. By pairing our DS15 or DS25 HPFP with our proprietary N55 Lift Kit (cam upgrade), this package delivers up to 49% more direct injection fuel flow — unlocking power levels never before possible with the OEM DI system.

This is achieved by starting with genuine BMW vacuum pump cores, retrofitted in-house with our Dorch-engineered high-lift fuel camshaft, using custom-built tooling and flow validation processes. The result: OEM-level reliability with massive flow gains — all fully controlled by the factory DME.

🔥 Performance Specs

Lift Kit Size HPFP Version MIN E10 Power Req. MAX E10 Power MAX E85 Power
+38% DS15 N/A 700whp 560whp
+49% DS15 N/A 750whp 610whp
+38% DS25 430whp 900whp 690whp
+49% DS25 500whp 1000whp 770whp

💡 Note: The +49% Lift Kit requires a minimum power level when paired with the DS25 pump to ensure safe, tunable operation. This restriction does not apply when using the DS15 pump.
