FG FPV F6/FGX XR6 Sprint | HPF Stage 5 | 500kW+

The HPF Stage 5 upgrade for the Ford FG FPV F6, FGX XR6 Sprint starts with our trained technician fitting a Stainless Steel 4" dump pipe and 3.5" turbo back exhaust system. We then remove the standard turbo and replace it with a brand new Garrett Pro GTX 64 fitted with a 42mm flapper valve and a 10psi Actuator - capable of 500RWkw. We then fit Process West's 'No Cutting' Stage 1 Stepped Intercooler kit including CNC mandrel bent intercooler piping and silicone hoses to maintain reliability and keep intake temperatures under control for constant, dependable power..

The Battery then gets relocated to the passengers side of the engine bay to make way for the Process West 4" to 4" 'Race' cold air Intake for the ultimate in air flow to your turbo. Fuel supply to the engine is then enhanced with a set of high performance E85 compliant fuel injectors, an external surge tank with the new Process West E85 compliant dual Walbro 460 fuel pump system, high flow pressure regulator and plug in wiring kit! We then tune your vehicles ECU on the dyno in real time utilizing the latest Ford ECU tuning software to maximize power, torque and fuel efficiency.

We complete the upgrade process by testing your vehicle on the road to make final adjustments, optimizing your vehicles performance and driveability. At the end of this upgrade we will provide you with a dyno graph comparing the before and after power & torque increase the HPF upgrade has made to your vehicle. Like all HPF upgrade packages this package is modular in that it allows the customer to add to the package minimizing the requirement to spend money twice when and if further upgrades are desired. HPF strive to bring you maximum performance with high quality components while still maintaining reliability and driveability.
