HPF STAGE 4 | 460KW

FG FPV F6/FGX XR6 Sprint | HPF STAGE 4 | 460KW

The HPF Stage 4 upgrade for the Ford FG FPV F6 and FGX XR6 Sprint is designed to deliver substantial performance improvements through a complete set of high-quality modifications. The process begins with our trained technician fitting a set of Crow Cams race series valve springs and retainers, which enhance valve control with higher boost levels. 

Next, we install a stainless steel 3.5-inch turbo back exhaust system paired with a 4-inch dump pipe. This upgrade significantly enhances exhaust flow, reducing back pressure and promoting greater efficiency. The standard turbo is then removed and replaced with a brand new Garrett GTX3582 Gen 2 turbocharger, equipped with a 42mm flapper valve and a 12psi actuator, capable of delivering impressive power levels of up to 500RWKW.

To support these power increases while maintaining reliability, we fit Process West's Stage 2 Stepped Intercooler kit, which includes CNC mandrel-bent intercooler piping and silicone hoses. This system is essential for keeping intake temperatures controlled, enabling constant and dependable power output. Additionally, the battery is relocated to the passenger's side of the engine bay to accommodate the Installation of the Process West 'Race' cold air intake, designed to provide optimal airflow to the turbo.

Fuel supply enhancements are made with the installation of high-performance injectors and a high-flow fuel pump, ensuring that the engine has the fuel necessary to match its increased power capabilities. Following these modifications, the vehicle’s ECU is tuned in real-time on a dynamometer using the latest Ford ECU tuning software. This tuning is critical for maximizing power, torque, and fuel efficiency.

The upgrade concludes with thorough road testing to make any final adjustments, ensuring that the vehicle’s performance and drivability are fully optimized. At the end of the upgrade, we provide a dyno graph that compares the vehicle's power and torque before and after the HPF upgrade, clearly demonstrating the substantial performance enhancements achieved.

This comprehensive Stage 4 upgrade reflects HPF's commitment to delivering exceptional performance through high-quality components while maintaining reliability and driveability throughout the process.

Notes

• At some stage upgraded valve springs will be required for maximum output. Requirement will depend on power output, age and condition and specific vehicle model.
• *Please note: Power figures are estimates only and actual figure's may vary.
• We recommend all vehicles coming to HPF for tuning run 98 Octane fuel. Please contact us if you have a need to use different fuel.
• Power figures listed are estimated kilowatts at the flywheel based on results typically obtained by HPF on HPF’s dynos. Typically these are based of a manual vehicle with standard driveline and standard wheels and tyres. Actual power can vary based on each specific vehicle.
• Modifications such as this package require the vehicle to be in excellent mechanical order.
• We advise against increasing the power output substantially on high kilometer engines, if your engine has in excessive of 150,000kms please contact us to discuss options.
• Whilst every attempt is made to ensure prices listed online are correct, they are subject to change at any time.
• Additional parts may be required in some cases depending on the condition of the vehicle. Cost of these parts and additional labour required may incur additional cost.
