B58 HPFP Flow Capacities
The table below serves as a reference for the maximum fuel flow in cubic centimetres 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.
Pump Model | Fuel Flow (cc/rev) |
---|---|
HDP5 Evo (Stock B58) | .954 |
HDP6 (Stock B58TU) | 1.178 |
Dorch Engineering Stage 1 | 1.299 |
Dorch Engineering Stage 2 | 1.558 |
