The ULTIMATE Bolt On Fuelling Upgrade for B58! HE140i Dorch DS25 Fuel Pump Installation and Review

In this video we run you through the installation and conduct a review of the Dorch DS25 High Pressure Fuel Pump. Alongside this, we also install updated injectors and new spark plugs - all in preparation for the HE140i to once again hit the dyno, this time aiming to flow a respectable ethanol percentage and hit 700bhp and beyond. www.hackengineering.co.uk facebook.com/hackengineering instagram.com/hackengineering Products featured in this video: Dorch Engineering DS25 HPFP Upgrade (Gen 1 B58) - https://www.hackengineering.co.uk/pro...
