DORCH B58 Steg 2 HPFP Uppgradering

Instruktioner är på Engelska och direkt från DORCH hemsida

After months of R&D we have finally released the world’s first B58 HPFP upgrade! Our Stage 2 kit is a bigger, better version of our Stage 1 kit for some of the more extreme applications. This is a complete plug-and-play kit to support up to 700whp and also allow for full E85 up to 550whp (these numbers 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.

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.
