B58 HPFP & LPFP Flow Rate Data

Comprehensive fuel pump flow rate data for BMW B58 and B58TU engines.

Note: HP figures are calculated using standard BSFC (Brake Specific Fuel Consumption) ratios, as such they may not represent the true maximum power the car can make for a given fuel.

The B58 uses an exhaust cam lobe for HPFP operation:

  • Gen 1: 3 x 5mm (3 lobes with 5mm lift)
  • Gen 2 & Up: 3 x 5mm (3 lobes with 5mm lift)
