We are proud to offer a game-changing product for the S55 community! With this innovative solution we are able to push +38% more fuel flow out of the OEM HPFPs! We start with Genuine BMW vacuum pump cores and install our Dorch Engineering Cams within the OEM assembly using our proprietary manufacturing tooling and validation equipment. What you end up with is a ton more fuel flow in a very simple and clean package, all while utilizing the OEM HPFPs. Since the S55 engine uses some of the smallest fuel pump cams in the Bosch lineup, we are able to achieve this additional flow without sacrificing any of the longevity or reliability of the OEM pumps. There’s no cutting, no bending, no crimping, etc. This kit drops right in like factory and it does not require any special tuning to get up and running. All of the safety and sophistication of the stock DME remain in place.

S55 HPFP Flow Capacities

The table below serves as a reference for maximum fuel flow in cubic centimeters per camshaft revolution for various S55 fuel pump options.

Pump Model	Fuel Flow (cc/rev)
HDP5 (Stock S55)	1.527
HDP5 w/ Dorch Lift Kit	2.100

Software changes are NOT required to run this upgrade. However, we do have preset optimized maps available via Bootmod3 and MHD. Simply check the box for our “Lift Kit” upgrade when flashing.

NOTE: The S55 fuel system is very much limited by the injectors. In order to see the true benefits of this kit, it is highly recommended to upgrade to the larger S63 EU5 Injectors.

BREXIT 2021 EUROPEAN TAXATION CHANGES:

For European Customers prices now displayed in cart once you enter your address will have 20% UK VAT Tax removed, however you will have to pay some form of Duties / VAT prior to delivery of your goods.

Do we ship abroad ?

Yes we do, to almost anywhere in the world though remember the postage is often high when shipping anything bulky. Most bulky items we export will go by UPS so you can track the package online and could reach America within 48 hours providing its in stock !

However there are a few countries we do not ship to, some of these include: Thailand, Malaysia, Indonesia, Russia, Nigeria, Macedonia, Syria, Ukraine, Lebanon.

Why is postage on bulky items to some countries expensive compared to some other companies ?

For both yours and our safety we use well known couriers such as DPD Local and UPS for shipping, then we know exactly where it is in the world at any time and we know its going to arrive safely. Shipping small items can be cheap, but items such as bodykits are expensive to ship - we have a very small margin on the postage fees merely to cover packaging. We can now ship using standard post on some items, however using all methods you may incur import charges when you receive the goods for which we cant be responsible for.
