300+hp and over 200lb-ft the RX8 is now a force to be reckoned

SHORT VIDEO CLIP


Over two years of R & D with road and track testing:

1.+60–80 HP
2.+50-70 lb-ft
3.Superb Drivability
4.Fast and Reliable
5.D.I.Y. Installation
6. Fits all RX8 models 6 port, 4 port, auto etc…
7. $5495.00 kit only

Already a superb handling drivers car, the extra power from Pettit’s system is just what the doctor ordered. “Wow! A most impressive yet refined driving experience.”

At Pettit, the same technology that won our Racing Championships is used to design, develop and produce our parts. This enables us to provide extremely reliable products giving you many miles of driving fun and excitement.

Aside from just providing extra power, here at Pettit we are creating several stages and levels of performance, in order to complement a variety of driving styles.

Pettit Racing strives to provide the highest quality components and workmanship. A fully CAD Designed System, a top rated Lysholm twin-screw compressor and all CNC machined billet drive pulleys, means you get a top quality system with parts that fit. Even our new Charge Chiller System (air to water intercooler setup) is designed with the latest technology and highest quality parts. This new system uses an advanced Jabsco Flojet Pump, dual Hayden Heat Exchangers and an internally finned tube Liquid I/C Core.

This Kit fits all RX8 engines both 6 port hi power as well as 4 port and autos, for use on the 4 port engines you simply put freeze plugs in the manifolds six port runners, later they can also be removed for use again on a 6 port, if need should ever arise.

Highlights:
70-90 additional horsepower and 50-70 lbft torque with only 6-8 psi boost
Superb drivability and overall performance
Reliable and easy to maintain
D.I.Y. installation, with easy to follow instructions
Offer stages and configurations to suit most applications.
Use only the highest quality components

Stages:
Stage 1 System, still under development, non intercooled producing 235 hp @8500 and 155 lb ft tq. @ 5500 with 4- 5 psi boost.
Stage II System, intercooled, producing aproxmately 260 whp @8500 and 185 lb/ft torque. @ 5500 with 6- 8 psi boost, this translates to 160 lb/ft of torque by 3500 RPM.
Stage III System, Hi Boost, still under development.

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

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

Charge Chiller System:
A Pump and Reservoir, with 2 Hi Efficiency Heat Exchangers providing 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 Forced Induction 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 fined extruded tubes oven brazed to the headers. This design has proven to be the most efficient for this application.

Management:
Interceptor X EMS is our current choice for engine management, we have tested E-Manage and Unichip systems which will also work; however, our initial release will be priced without management. For those who already have the Interceptor X we will provide tuning maps at no charge. For those who don’t it can be purchased from us pre-mapped.

Intake manifold:
Another result of our lengthy development process is our new aluminum upper intake manifold. It redirects the six port intake runners and provides improved overall flow. This new maniflold replaces both parts of the stock plastic intake manifold assembly. The new manifold is included with Pettit’s RX 8 Compressor Kit.
This new manifold 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
Another cool features is cool air circulation for the ignition coils, this simple setup will surely improve coil performance as well as reliability.

C.A.R.B.
We will also be working on C.A.R.B. cert.

F.A.Q.
Q: What is a compressor and how does it work?
A: A compressor forces compressed air into the engine, more air than is possible under normal atmospheric conditions there by allowing more fuel to be added, thus creating more power

Q: How much horsepower will I get?
A: Pettit offers compressor systems with factory settings from 5-8 psi of boost pressure. This level of pressure typically results in a 35%-50% increase in horsepower, for the RX8 with our stage 2 kit aprox. 90 hp can be expected. Although, higher boost can be achieved by changing drive ratios, it is also necessary to make sure the management compensates for these changes. Pettit does not recommend exceeding 8 psi with the stock injectors.

Q: Is the compressor always working?
A: While the compressor is always spinning and moving air, it is not always producing boost. Our design utilizes a hi flow internal by pass valve which helps reduce charge temps as well as allowing the compressor to free spin unless there is a demand for power. When accelerating with either moderate or full power the by pass valve closes, instantly providing power and torque. The majority of time the compressor will be free spinning and not producing boost.

Q: Will the compressor affect gas mileage?
A: Fuel economy depends entirely on your driving habits; in some cases you may experience an increase in gas mileage. For example, under normal freeway driving the compressor is free spinning but the intercooler is still reducing charge temperatures and increasing efficiency of the charge, this causes more efficient combustion which can improve fuel mileage. Clearly, you are not interested in more horsepower for conservative driving; when you demand additional performance from your vehicle it will require additional fuel. If you are a "lead foot" your fuel economy will decline because your car is working harder. If you are simply using the extra power for occasional acceleration and passing performance, your fuel economy will be affected respectively. During highway testing we achieved 20 MPG.

Q: Will the compressor affect engine life?
A: Engine longevity is a function of your personal driving habits and how well your vehicle is tuned. If a vehicle is tuned properly and not abused, engine life should remain unaffected. Even a stock vehicle will show signs of premature aging if used under rigorous conditions such as racing and/or towing. Likewise, premature engine failure is a possibility with any vehicle that is not properly tuned and a boosted vehicle is no exception.

Q. Will the engine ping with the compressor?
A. Detonation (a pinging noise from the engine) is a sign that your vehicle is not running properly and can indicate a variety of problems including poor fuel quality and/or elevated operating temperatures. If detonation occurs avoid that operating range until better fuel is obtained or the problem is corrected. Demanding performance from a detonating engine will likely result in reduced engine life or engine failure.
