Instruktioner är på Engelska och direkt från DORCH hemsida 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 650whp and also allow for full E85 up to 500whp (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.  

N55 HPFP Flow Capacities

The table below serves as a reference for maximum fuel flow in cubic centimeters per camshaft revolution for various N55 fuel pump options. These calculations are based on the N55 cam lobe. Each engine will have varying fuel flow capacities depending on the lift and number of lobes on the camshaft.

HDP5 Evo (Stock B58)	0.897
