Welcome to the home of the highest powered direct injection N55 cars on the planet! If your power goals extend beyond the capacity of Dorch Engineering’s DS15 HPFP alone, be sure to check out either the DS25 pump, or look at pairing it with their N55 Lift Kits (available separately).

Dorch’s widely successful “Dorch Stage 1” (DS1) has been replaced with their latest and greatest creation; the DS15. This new pump is their “Stage 1.5” which has been completely redesigned and optimized from the ground up. Externally, the pump packaging has been updated to provide improved hose routing for even easier installations. Internally, Dorch re-worked the pressure chamber, spring rates, plunger depth, and completely optimized the volumetric efficiency of the pump.

What does this mean? It means the most reliable and highest flowing N55 pump on the market just got even MORE reliable and even MORE flow! The DS15 is also designed to run efficiently all the way up to 250 bar in order to maximize the flow potential of upgraded DI injectors.

Just like the previous generation DS1 kit, there’s no cutting, no bending, no crimping, etc. This kit drops right in with full control from the DME, just like the OEM pump. All of the safety and sophistication of the stock DME remain in place. Software changes are required to run this pump. If using MHD or Bootmod3, simply check the box for our pump upgrade when flashing. Otherwise, please send your .BIN file to tuning@dorchengineering.com for the appropriate software implementation via WinOLS.
