VF 6.0L Harrop Stage 4 | 390kW

The Harrop VF Stage 4 upgrade starts with our trained technician fitting an over the radiator cold air intake with a re-usable air filter and a full Harrop Pro-Extreme exhaust system, including 4 into 1 extractors and new dual 3” exhaust system all to increase the engine’s breathing capabilities and to give it that nice “V8” sound we all love. After all the new performance components are fitted we custom tune your vehicle’s ECU on the dyno utilizing the latest tuning software to maximize power, torque and fuel efficiency.

Our trained technician then fits a new Harrop high performance camshaft and valve spring package that has been carefully selected by one of our sales technicians to match your driving and vehicle requirement.

We complete the upgrade process by testing your vehicle on the road to make final adjustments, optimizing your vehicles performance and driveability. This is all completed in a day and at the end of this upgrade you will be provided with a dyno graph detailing the power & torque increase of your vehicle.
