HPF STAGE 5 | 850KW

RAM TRX HPF STAGE 5 | 850KW

If you’re looking for the ultimate TRX in performance and a sound that will scare old ladies, HPF has the ultimate upgrade package for your TRX. The HPF TRX Stage-5 upgrade starts with our trained technician setting your vehicle up on our 4WD dynamometer and performing a baseline dyno run. This allows us to firstly make sure everything is working A-OK and secondly it gives us a standard figure from your car to compare to once the upgrade is completed. We continue by removing the engine from the vehicle, setting it up on our custom-made jig and disassembling it to replace the factory camshaft with a high-performance custom camshaft and a phaser limiter kit from Crow Cams.  HPF is not shy in leveraging Crow Cams extensive testing and as such, our product list for the Hemi cam packages includes Crow's camshafts, valve springs and Phaser limiter / lock. We then replace the factory hydraulic lifters with premium Johnson high performance lifters which feature a redesigned oil pathway to lubricate and pressurize the lifter. Next, we fit upgraded valve springs to the cylinder heads and we reassemble the engine with new heavy-duty pushrods, head gaskets, an ATI Super Damper 10% overdrive balancer and ARP head studs. While the engine is out and, on the jig, we install a new larger 3.0L Whipple Intercooled Supercharger with a 3.35” high boost GripTec® pulley along with a HHP adjustable billet alloy belt tensioner mount, 160-degree thermostat, 1500cc Excess fuel injectors, a set of Pacemaker 1-7/8” primary 4-1 headers (extractors), ported OEM throttle and Brisk Spark plugs. Once the engine is reinstalled, we install a massive high flow aFe Magnum cold air intake and bolt the Pacemaker dual 3” cat-back exhaust system and high flow metallic catalytic converters to the headers. We then custom tune your vehicle's ECU on the dyno utilizing the latest ECU tuning software to maximize power and fuel efficiency. We complete the upgrade process by testing your vehicle on the road to make final adjustments, optimizing your vehicle's performance and driveability. This is all completed in around 4-5 days and at the end of this upgrade you will be provided with a dyno graph detailing the power & torque increase of your vehicle. Flex Fuel (E85) is an option, talk to one of our Sales Representatives.

• Cold air intake - Take your RAM 1500 TRX 6.2L to the next level with the S&B Cold Air Intake, a perfect solution for supercharged applications. This system enhances performance by improving acceleration, horsepower, and torque, all while protecting your engine from debris. Featuring a large oval inlet measuring 4.125" x 6.75", it allows for unrestricted airflow, providing remarkable efficiency. With a 4” mouth designed for supercharger compatibility, this intake is ready to support your future upgrades. Enjoy sound-activated performance that adds a powerful and exhilarating experience to your ride, while ensuring harmful particles are kept out of the engine to prolong its lifespan.
• Thermostat - HPF offers this premium quality 160-degree thermostat for Hemi Applications. This is a direct drop in with no modifications needed and includes the rubber seal. Reducing engine coolant temperature will help produce more horsepower and improve performance and driveability. The thermostat is an easy to install component and requires no mechanical modifications.
• Whipple Supercharger -  The innovative Gen 5 Supercharger System, compatible with Trackhawk models, now offers an extraordinary benefits – This enhancement allows you to fully exploit the capabilities of the Whipple 3.0L Twin-Screw Supercharger, delivering exhilarating performance gains with the right fuel choice.
• Supercharger pulley - The high boost supercharger pulley includes the ZPE Pulley Hub system for the factory supercharged 6.2 Hemi. The Pulley is made from billet 7075-T6 aerospace grade aluminium, stronger and harder than 6061 T6. This pulley is equipped with GripTec® - a unique micro machining technology. This technology allows the maximum grip force to be applied to the component and belt without damaging your belt. Made in California, USA.
• Catback Exhaust system – A ‘Catback’ system is basically all the parts of the exhaust after the catalytic converters. It’s the section of exhaust where all the mufflers are placed and by using larger diameter pipe and high flowing mufflers more performance and better sound is achieved. HPF chooses Pacemaker Exhausts for the RAM TRX platform. Made in Richmond, South Australia for almost half a century, Pacemaker are synonymous with performance and quality. Pacemaker build a quality stainless steel dual 3” system and some model specific quad-phat-tips for the ‘Hawk. The sound is deep and meaningful.
• Headers & High flow cats – Also known as extractors, we chose a 4-1 design as over the years 4-1 headers have proven their performance advantage over the tri-y design. 4-1 Headers are offered in a few different sizes for different engine applications or modification levels. The catalytic converters chosen are higher flow and feature 100 cpi (cell per inch) for TRX. The catalyst matrix is coated metal so they are built to last. Given the performance the TRX’s Hemi V8 is capable of producing, we choose Pacemakers 1-7/8” primary sized, 4-1 headers matched to Pacemakers 3” high flow cats. The catback exhaust bolts to the catalytic converters. Ceramic coating of the headers is optional, talk to one of our sales representatives.
• Fuel injectors - HPF only uses premium fuel injectors from Excess Fuel Injectors for the Hemi platform. All Excess Injectors are tested on a custom-built test bench to J1832 standards under strict testing protocol in a purpose-built facility in Melbourne’s South Eastern Suburbs. Every injector set is dynamically flow matched within 1% and deadtime matched within 2%, this minimises time tuning injectors and allows us to get a perfect result every time. We choose extra-large 1500cc to enable the change to E85 or the next level in performance without having to buy another set of injectors and the beauty of the Excess injector data is that our calibrators are able to get the car to still drive perfectly. These injectors come with a Lifetime Guarantee – ask for more info.
• Harmonic balancer – In the quest for more boost pressure we chose to add a premium ATI ‘Super Damper’ over-drive harmonic balancer as opposed to a smaller S/C pulley as this minimizes the chance of belt slip. The overdrive segment of the new harmonic balancer does not affect the non-supercharger related accessories run by the OEM drive belt. The ATI Super Damper comes in a 10% over-drive ratio for an additional 3-psi of boost and is pinned to the crank by our technicians to ensure it does not slip. ATI Super Dampers are OEM fitment on Mopar Hemi 392 crate motors and they provide balanced dampening of torsional crankshaft vibrations through all RPM ranges and exceed SFI 18.1 Safety Certification for competition use. ATI is based in Maryland, USA.
• Cam package (Hemi 6.2) – If you’re looking for a cam upgrade that sounds like a CAM UPGRADE then HPF has the package for you! Utilizing the latest technology, Crow Cams lead the way in valvetrain component design. HPF is not shy in leveraging Crow’s extensive testing and as such, our product list for the TRX / Trackhawk cam package includes Crow's conical valve springs and a Crow's camshaft phaser limiter / lock system. Supporting the Crow Cams components, we use high performance USA Made Johnson #2326 hydraulic lifters. The 2326 oil band is different because of the change in how the internals are provided oil. Factory lifters are supplied oil via the pushrod, whereas the Johnson 2326 are oiled by the oil gallery like a typical lifter – a true solution for the Hemi Tick. We finish the engine off with a set of HD Crow Cams pushrods.
• Dyno Tuning – By optimizing the engine tune parameters in the vehicles PCM to suit 98 octane fuel, we are able to increase both power and torque and maximise fuel economy. Late model naturally aspirated cars are generally tuned very well from the manufacturer so depending on the vehicle platform mechanical parts to improve the engines intake & exhaust flow may need to be added to really get good gains. Engines fitted with a turbocharger from factory are much easier to enhance as increasing boost pressure by tuning works extremely well.
