From the creators of the world’s first B58 direct-injection fueling upgrades, Dorch Engineering proudly introduces the B58 Gen 1 DS25 HPFP, the next evolution in high-pressure fuel pump technology for Gen 1 B58 engines. Replacing the Dorch Stage 2 (DS2), the new B58 Gen 1 DS25 HPFP — also known as Stage 2.5 — has been completely redesigned and optimized to deliver greater fuel flow and improved reliability, making it the most advanced and highest flowing HPFP for Gen 1 B58 engines.

The B58 Gen 1 DS25 HPFP features a refined exterior design, with updated OEM-matched hose routing, ensuring zero interference when changing coil packs or spark plugs, and guaranteeing a clean, factory-like fitment. Installation is fully plug-and-play, requiring no cutting, bending, or crimping, and it operates under full DME control, retaining all factory safety features and sophisticated fuel system management.

Internally, the B58 Gen 1 DS25 HPFP is equipped with an optimized pressure chamber, revised spring rates, deeper plunger depth, and enhanced volumetric efficiency, all working together to provide superior fuel delivery under demanding conditions. Capable of running at up to 250 bar, this pump is designed to fully support upgraded direct-injection injectors, enabling higher horsepower builds, big turbos, and ethanol blends with maximum reliability.

B58 Gen1 DS25 HPFP Specs DS25 DS25 + 40% Cam Upgrade
Flow Capacity Gasoline 750whp 1000whp
Flow Capacity E50 650whp 880whp
Flow Capacity E85 550whp 770whp

ADDITIONAL INFORMATION:

Brand

PREPREG is a common term for a reinforcing fabric such carbon which has been pre-impregnated with a resin system. This resin system (typically epoxy) already includes the proper curing agent. As a result, the prepreg is ready to be laid into the mold without the addition of any more resin. In order for the laminate to cure, an autoclave production process is used, a combination of high pressure and heat.

  • Maximum strength and performance characterictics. In a hand layup production process, it is difficult to achieve 50% fabric and 50% resin content.  Typical hand laminates, even when vacuum bagged, end up with a significant amount of excess resin. Excess resin increases brittleness and reduces overall strength properties. On the other hand, most prepregs contain around 35% resin. This is ideal for maximum cured properties and generally impossible to achieve in normal hand lamination.
  • Uniformity and repeatability. The prepreg is of uniform thickness and each part coming out of the mold may theoretically be the same. Vacuum bagging technology may have some errors in processing, but prepreg ensures production consistency.
  • Reduce curing time. After the thermal curing cycle, no need to wait for the standard 48 hours can be fully cured.
  • Aesthetics. Although prepreg processing still requires mold preparation and demoulding, prepreg processing eliminates air bubbles, makes it easier to obtain a smooth, glossy surface as well as eliminates any seaming lines.
