Highlights:

• 80-100 additional horsepower & +45-70 lb-ft torque with only 5-8 psi boost.
• Superb drivability and overall performance
• Reliable and easy to maintain.
• Allows for a simple D.I.Y. installation, with clear instructions.
• Offers several stages and configurations to suit most budgets.
• Uses only the highest quality components.
• Fits all models, 230 Hi Power and 190.

Variants:

Stage I:
Still under development, non intercooled producing at wheel 235 hp @8500 and 155 lb ft tq. @ 5500 with 4- 5 psi boost.

Stage II:
Intercooled, producing at wheel 280 hp @8500 and 185 lb/ft torque @ 5500 with 7- 8 psi boost, this translates to 180 lb/ft of torque by 3500 RPM.

Stage III:
Hi Boost, still under development. Will require further component uprating, e.g fuel system.

Pettit Racing Billet Aluminium Bypass Valve

Pettit’s billet aluminium bypass valve is now standard with the kit.

Machined from billet aluminium and anodised black for better looks this bypass valve allows faster transitions to full boost and can cope with higher boost pressures. It provides worry free motoring as it has no diaphragm which can fail, and is guaranteed for its lifetime

Pettit Racing RX8 Compressor System

Plug and play for REAL Zoom Zoom motoring! Pettit’s twin screw supercharger system for the RX8 gives the car the power and torque boost that propel it into the ‘perfect sports car’ range. 300+ HP means better acceleration, more flexibility in the gears and more power on the straights and uphill. Your RX8 will become the car you always dreamed it could be.  Easy to install, reliable and managed by the RX8’s on board PCM, Pettit’s supercharger targets the  RX8’s only real short coming and brings the power levels up to match its handling and braking abilities.

The kit is designed as the perfect match for a standard car, and no other systems require upgrading. Just plug and play for REAL Zoom Zoom motoring!

A simpler Stage I variant will be produced in the future, and for those hungry for even more power, an up-rated Stage III kit will also be released. (It will be possible to upgrade from a stage II system to a stage III system easily)

R&D:
Over two years of R&D with RX8s has resulted in several new products; to date we have logged over 30,000 miles and analyzed 400+ dyno runs. New RX8 products are still being developed. At Pettit R&D is ongoing and relentless; it makes our products #1.

Compressor:
We chose Lysholm because it is one of the most efficient twin-screw compressors on the market today. Made by the Opcon Group in Sweden, its advanced design provides a reduction in parasitic loss and charge temperature, which makes it more efficient than roots or centrifugal units.

Management:
The Pettit developed reflash system utilises the RX8’s original PCM (Powertrain Control Module, also known as the ECU or Engine Control Unit) and gives it the information required to safely use the supercharger whilst maintaining all of the factory systems. Improved cooling is also made available.

Charge Chiller System:
A Pump and Reservoir, with 2 Hi Efficiency Heat Exchangers provide a simple and effective system for maximum charge cooling which is suitable for use with most liquid intercoolers. The Charge Chiller System is included with our RX8 Supercharger System.

Liquid Cool Charge Intercooler:
Our Liquid Cool Charge System utilizes a very efficient liquid core built to Pettit specs. The simple design utilizes internally finned extruded tubes oven brazed to the headers. This design has proven to be the most efficient for this application.

Intake Manifold:
Our new aluminium upper intake manifold redirects the six port intake runners and provides improved overall flow. This new manifold replaces both parts of the stock plastic intake manifold assembly. The manifold is included with Pettit’s RX 8 Compressor Kit. It should also be a welcome addition for racing, turbo and hi boost applications where the stock plastic manifold proves inadequate.

Compressor by-pass:
The compressor bypass system allows the compressor to free spin during cruise and no load conditions. This improves efficiency and reduces charge temperatures, as well as providing better instantaneous power and torque, without lag. More of what compressors are known for.

Ignition cooling:
Cool air circulation for the ignition coils is improved, this simple setup will aid coil performance as well as reliability.
