The Highest-Flowing OEM+ Drop-In HPFP Solution for Gen2 B58 Engines

After extensive R&D, Dorch Engineering proudly introduces the DS3 HPFP—our most powerful high-pressure fuel pump yet. Built for serious power, this Stage 3 system delivers up to 1150whp with just a plug-and-play installation. With 20% more flow than the DS25, the DS3 redefines what’s possible from a single drop-in HPFP upgrade.

Performance Specs:
