HPF STAGE 3 | 365KW

JEEP 5.7L HPF STAGE 3 | 365KW

The JEEP 5.7L Stage-3 upgrade starts with our trained technician fitting a high flow K&N Cold air intake system which K&N guarantees to increase power and torque buy increasing the engines breathing capabilities (and they sound great!). We continue with a Pacemaker dual 3” cat-back exhaust system, 4-1 headers (extractors) and high flow metallic catalytic converters. The exhaust and intake increase the engines breathing and improve the overall V8 experience, the same as Stage-2. Stage-3 goes further with our tech removing the engine from the vehicle and disassembling it to replace the factory camshaft with a high-performance custom camshaft and a phaser limiter kit. We then replace the troublesome MDS lifters with high performance items and fit upgraded valve springs to the cylinder heads. Next, we reassemble the engine with new HD pushrods, head gaskets and head bolts. 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 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. Flex Fuel (E85) is an option, talk to one of our Sales Representatives.

• Cold air intake - The K&N Cold Air Induction (CAI) system features a large diameter free-flowing intake path to ensure maximum performance from your Hemi powered vehicle. It features a large surface area pod style air filter to assist in minimizing the restriction of air flow and is contained in a fabricated housing which seals against the underside of the vehicles bonnet to reduce the intake of hot air from inside the engine bay.
• 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 Jeep, SRT & Trackhawk 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 phat tips. 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 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 either 100 cpi or 200 cpi (cell per inch). The catalyst matrix is coated metal so they are built to last. Given the performance the Hemi V8 is capable of producing we have the choice between Pacemakers 2” 4-1 headers for blown applications and 1-7/8” Headers for naturally aspirated applications all matched to their 3” high flow cats. The catback exhaust bolts to the catalytic converters.
• Cam package (Hemi 5.7 & 6.4) – Utilizing the latest in Spintron technology, Brian Tooley Racing (BTR) in Kentucky, USA lead the way in valvetrain component design. The Spintron machine allows BTR to effectively test and design camshaft and valvetrain products to ensure stability and longevity like no other device. HPF is not shy in leveraging BTR’s extensive testing and as such, our product list for the cam package includes BTR’s camshaft, Platinum conical valve springs and a BTR camshaft phaser limiter. Supporting the BTR components, we use heavy duty performance hydraulic lifters and Crow Cams pushrods. We offer camshafts to suit naturally aspirated and supercharged applications.

• 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.

Notes

• *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 labor required may incur additional cost.
