    • Mission Performance delivers on BMW B58 HPFP upgrade - Pure Stage 2 F30 340i with HPFP upgrade hits 512 whp on ethanol DI only

      Color BimmerBoost shocked but it looks like Mission Performance actually pulled off the B58 HPFP (high pressure fuel pump) upgrade they promised back in March of this year. BimmerBoost would like more details but if the provided dyno graph is not lying they are making over 500 whp direct injection only.


      Not only with direct injection but with pump E85 (blended to E65 here):


      The peak figures of 512 horsepower and 450 lb-ft of torque at the wheels are nice but where is a high resolution graph? How about a boost readout? What about the air/fuel ratio?

      What is the cost for this HPFP upgrade?

      How much more can it support or is this about the limit for the upgraded HPFP?

      Many questions remain.
