After months of R&D we have finally released the world’s first B58 HPFP upgrade! This is a complete plug-and-play kit to support up to 600whp (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.

Software changes are required to run this pump. If using MHD or Bootmod3, simply check the box for our pump upgrade when flashing. Otherwise, please send your .BIN file to tuning@dorchengineering.com for the appropriate software changes. This change is free of charge for all of our customers.

*Full E85 is tuner-dependent, but we typically recommend our Stage 2 HPFP Upgrade kits
