Dorch engineering B58 Stage 1 HPFP Upgrade
Dorch engineering are proud to offer the world’s first B58 HPFP upgrades! This is a complete plug-and-play kit to support up to 560whp 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.
B58 HPFP Flow Capacities
The table below serves as a reference for maximum fuel flow in cubic centimeters per camshaft revolution for various B58 fuel pump options. These calculations are based on the B58 cam lobe. Each engine will have varying fuel flow capacities depending on the lift and number of lobes on the camshaft.Pump Model | Fuel Flow (cc/rev) |
---|---|
HDP5 Evo (Stock B58) | .954 |
HDP6 (Stock B58TU) | 1.178 |
Dorch Engineering Stage 1 | 1.299 |
Dorch Engineering Stage 2 | 1.558 |
Software changes are required to run this pump. If using Bootmod3, MHD, or MG Flasher, simply check the box for our pump upgrade when flashing.
