Description

We’re proud to introduce our latest generation of pumps! Our widely successful “Dorch Stage 1” (DS1) has been replaced with our latest and greatest creation; the DS15. This new pump is our “Stage 1.5” which has been completely redesigned and optimized from the ground up. Externally we’ve updated the pump packaging to provide improved hose routing for even easier installations. Internally, we’ve re-worked the pressure chamber, spring rates, plunger depth, and completely optimized the volumetric efficiency of the pump. This is now a 250 bar capable pump and here’s the gains to be expected at 200 bar:

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 changes. This change is free of charge for all of our customers.
