Our Stage 2 kit is a bigger, better version of our Stage 1 kit for some of the more extreme applications. This is a complete plug-and-play kit to support 650whp and also allow for full E85 up to 500whp (these numbers can vary quite a bit depending on tuning strategy, fuel type, etc.). 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.

N55 HPFP Flow Capacities

The table below serves as a reference for maximum fuel flow in cubic centimeters per camshaft revolution for various N55 fuel pump options. These calculations are based on the N55 cam lobe. Each engine will have varying fuel flow capacities depending on the lift and number of lobes on the camshaft.

Pump Model	Fuel Flow (cc/rev)
HDP5 (Stock N55)	0.837
HDP5 Evo (Stock B58)	0.897
HDP6 (Stock B58TU)	1.107
Dorch Engineering Stage 1	1.221
Dorch Engineering Stage 2	1.465

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.

Performance M Delivery Information

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. If you are unsure of charges we recommend you should contact your local authorities ahead of placing your order.

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.
