While the factory fuel system is adequate for stock vehicles these engines quickly run out of fuel with even basic performance upgrades. To help combat this, we are introducing the first High Pressure Fuel Pump (HPFP) for the N55 direct injection engines! Our extensive work with Xtreme-DI has revealed this pump can expand the tuning and performance opportunity of your N55 motor. This is a complete bolt on upgrade and comes with everything needed to make installation a breeze. As you know the price can not be posted here, but it is far lower than our dual pump setup which has a higher fuel capacity.
The installing of the pump is fairly easy but, it must be accompanied by our custom base tune to work correctly which, is included with your purchase and you can use our tuning services for performance tuning or have your preferred tuner take your N55 to the next level with this brilliant upgrade!
Maximum Flow Rate: 195LPH @ 7000rpm
Maximum Rail Pressure 200bar / 2900psi (like OEM)
Fuel Compatibility: all known fuels, all Ethanol blends
Mechanical Data Geometric Pump Capacity 1.22cc (OEM = 0.897cc > +36% capacity)
After doing our own R/D testing we decided to ask an old time friend and industry leader Active Autowerke to do some independent testing and here was their results with an M235i with a Pure Stage 2 (PS2) and our pump on a mustang dyno. As you can see from the data it is supporting 425 wheel horse power and 500 wheel torque on a mustang dyno with pump gas only.
