Dorch Engineering

Dorch Engineering builds high-pressure fuel pumps for direct-injection BMW engines — the platforms that hit a fuel-delivery wall before a mechanical one. We carry their HPFP upgrades, lift kits, and flex-fuel adapters for builds committing to E-blends or higher targets, where the factory pump can no longer feed the calibration cleanly.
WHY WE SHIP DORCH ENGINEERING
Dorch Engineering fills the gap where a single fuel system runs out of injector or pump to feed the power a build is asking for. Their high-pressure fueling work is built for the direct-injection BMW engines that hit a fuel-delivery wall before they hit a mechanical one. We choose Dorch when a customer commits to ethanol content or big-power targets that the factory HPFP and DI injectors can no longer support cleanly. This is fueling for the upper end of a build, where getting the supply right is the difference between a calibration that holds and one that runs lean where it matters.
