DORCH ENGINEERING - Finally, A B58 HPFP Upgrade! Huge Introductory Sale!


Although we may be a new name to most people, we are no strangers to the automotive aftermarket! We are a small team of engineers with diverse backgrounds in various fields and disciplines of engineering, but each of us has a passion for the automotive aftermarket. We are the designers behind some of the biggest corporate names in the world and we are now bringing that expertise directly to the consumer! Our philosophy is to cut-out out any middle man operations to be able to offer the highest quality products at the best possible prices. We design, manufacture, test, package, etc. all in-house to control costs and ensure quality.

B58 HPFP Upgrade

We are enthusiasts over all else, so we have heard (and shared) your cries for an affordable HPFP solution! After months of R&D we are happy to announce the world’s first released B58 HPFP upgrade! (Which will be shortly followed by an N55 variant) We have provided GDI solutions for a number of years prior to our involvement with the B58 engine. Over the years we have developed very reliable testing standards and ECU calibrations to give you an OEM-level product that pumps A LOT more fuel! Here’s how we stack up against the OEM pumps in terms of maximum fuel flow in cubic centimeters per camshaft revolution:

Keep in mind that these flowrates only apply for pumps mounted on the OEM B58 cam lobe. N55 for example, will have about 6% lower flow rates due to the slightly smaller cam lobe.

Kit Features

This kit is 100% plug and play. 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 (the car will not start without the changes). If using MHD or Bootmod3, simply check the box for our pump upgrade when flashing (check boxes coming soon). Otherwise, please send your .BIN file to tuning@dorchengineering.com for the appropriate software changes. This calibration file is free of charge for all of our customers.

Kit Performance

Flow rates don’t lie, but power output capacities for each of our kits can vary depending on the tuner, the fuel, etc. That being said, you can expect our Stage 1 kit to support up to about 600whp and we recommend mixes of ethanol up to E50. For our Stage 2 kit you can expect at least 550whp on full E85 and at least 700whp on E10. We have successfully run these pumps for the past 6 months with great results, but don’t take our word for it, stay tuned for our beta testers’ results! We will be adding dyno sheets and log files very soon!


As a service to our fellow BMW enthusiasts we are running a blowout sale of complete turn-key kits starting at $999! This is essentially our “Cyber Monday” deal, but we are running it until 2020 while supplies last!

Please visit our website for purchases and more information and follow us on Instagram and Facebook to keep up to date with our latest announcements.

Welcome! Stage 1 and Stage 2 same price or no? Just wasn’t sure as Stage 2 not listed on website? Looking forward to this! MHD support will be amazing!
