Description

Months of R&D resulted in Dorch Engineering producing the original, and the best, B58 HPFP upgrade.

This is a complete plug-and-play kit to support up to 560whp on E10 pump fuel (this number can vary quite a bit depending on tuning strategy, fuel type, etc.). 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.

The table below serves as a reference for maximum fuel flow in cubic centimetres 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.

Software changes are required to run this pump – this is made as easy as a few clicks if using Bootmod3. Otherwise, please send your .BIN file to tuning@dorchengineering.com for the appropriate software changes. This change is free of charge.
