HPF STAGE 2 | 650KW

RAM TRX HPF STAGE 2 | 650KW

The HP-F Stage 2 Performance Package for the RAM TRX has been developed to unlock the next level of performance from the supercharged 6.2L Hellcat V8. Combining increased supercharger boost, enhanced intake airflow, upgraded fuel delivery and a complete performance exhaust system, this package delivers substantial gains in horsepower, torque and throttle response while maintaining the drivability and reliability expected from RAM's flagship performance truck.

Every upgrade begins with a comprehensive pre-upgrade dyno assessment, establishing baseline power and torque figures before any modifications are carried out. This provides an accurate benchmark and allows us to clearly demonstrate the gains achieved throughout the upgrade process.

At the core of the package is a ZPE GripTec 2.85-inch Supercharger Pulley Upgrade and heavy-duty drive belt, designed to increase supercharger speed and generate additional boost pressure from the factory supercharger system. The result is stronger acceleration, increased torque and significantly enhanced power delivery throughout the rev range.

To maximise airflow into the engine, Stage 2 incorporates an AFE Momentum GT Cold Air Intake System, allowing the supercharger to draw a greater volume of cool, unrestricted air. This improves supercharger efficiency and supports the increased airflow demands of the upgraded boost package.

Supporting the additional power is a set of XS1500 high-flow fuel injectors, providing the fuel delivery capacity required to safely support increased boost levels and horsepower. These upgrades ensure consistent fuel delivery and reliable operation under demanding driving conditions.

Engine breathing is further enhanced with a complete Pacemaker Performance Exhaust Package, featuring ceramic-coated 4-into-1 long-tube headers, high-flow catalytic converters and a dual 3-inch exhaust system. This dramatically improves exhaust flow, reduces back pressure and allows the Hellcat V8 to operate more efficiently while delivering an aggressive supercharged V8 soundtrack.

A 160-degree thermostat is installed to assist in maintaining optimal operating temperatures under increased performance demands, supporting both consistency and reliability.

To unlock the full potential of the hardware upgrades, HP-F performs a bespoke ECU unlock and custom dyno calibration tailored specifically to your vehicle. Extensive dyno testing is utilised to optimise boost control, ignition timing, fuel delivery and throttle response, ensuring safe, reliable and repeatable performance gains.

The result is a RAM TRX that feels significantly stronger throughout the entire RPM range, delivering brutal acceleration, immense torque and an even more exhilarating driving experience both on-road and off-road.

Once tuning is complete, every vehicle undergoes comprehensive dyno validation and testing to verify performance, drivability and reliability. A final dyno run is then completed to compare against the original baseline figures, clearly demonstrating the gains achieved through the Stage 2 package.

At the completion of the upgrade, you'll receive a detailed before-and-after dyno report showcasing the final power and torque improvements. The result is a RAM TRX that delivers exceptional supercharged performance, improved throttle response and serious real-world performance gains.

Take your RAM TRX to the next level with HP-F's professionally engineered and dyno-tested Stage 2 Performance Package.

Notes

• 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 labor required may incur additional cost.
