Mechanical Engine Performance

The Bosch P7100 fuel pump is the heart of the early Cummins 5.9 and 8.3 engine performance.

BD has designed a fuel calibration plate that can be installed in the Bosch P7100 fuel pump.. We offer 5 different ramp designs of this fuel plate that can result in 30 to 150 hp and 70 to 300 lbs of torque increase. The kit comes with a calibrated orifice that improves your turbo performance. No turbo or turbine housing change is required on most motor homes but please call our technical department for assistance in designing your performance curves.

We recommend this kit be installed by one of our dealers. It requires opening up the fuel pump and precise setting of the plate to insure the proper adjustment to prevent over fueling of the engine.
