| “Pettit Racing’s Forced Induction System puts the Mazda RX8 on par with Great Road Cars of the World”
300+hp and over 200lb-ft the RX8 is now a force to be reckoned
Over two years of R & D with road and track testing: 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, mean 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 a bar/ plate type Liquid I/C Core.
Our FI kit fits all RX8 models, US & Euro spec, with manual or automatic
transmissions, as well the PCM-FI recal kit also works with nearly
every PCM, however there may be some PCM’s like euro spec 4 port 5
speeds that will require some user feedback and additional fine
tuning, this is included in the price.
Our latest release Stage II “CS” is capable of 285-300
whp and includes the addition of a hi flow cat. These figures were
achieved using our PCM-FI recal kit but any management properly
tuned, should provide similar results.
Our latest testing
on 5 different RX8’s has consistently
yielded 278 - 300 whp through the stock exhaust with the latter
using a hi flow cat. We will continue testing other combinations;
like the stock cat with performance cat back system etc, etc.
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. More Information »
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 manifold 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. |
