Hello Downunder- I have one of the Avenger/Magnuson superchargers on my 2003 4.0L and have been very pleased with it. As the Ripp rep has said-the setup will require some tuning to get it running right. The pre-2005 Jeep has no ECU tuner support available from any manufacturer that I am aware of. As such, a piggyback system that uses the stock ECU is necessary.
If you decide to go with Avenger (which I am very happy with personally), you need to contact Mr. Jack Schuler thru their website. I will try to find a phone number if you desire when I get home. Their setup will only come at a low boost range and to really get it running with some steam requires some changes. If you desire, I would recommend several things to really boost the performance:
Get a higher boost pulley from Pulley Boys-around 8-10 psi boost
Bigger injectors-33-35lb Ford Racing work nicely
Split Second Programmable MAP Sensor
Split Second Fuel Enricher
Good Wideband gauge (I like Autometer)
A good Scan tool that gives live data on fuel trims
Some good time to spend tuning your MAP sensor fuel map
I run mine at 1mi altitude, being in Perth you may need to drop the high end boost a little, depending on the quality of your premium gasoline. I have a nice map figured out for my setup and would be willing to share some information in getting one to work for you.
Oh-and since you are in Perth---------
Could you get me a good deal on a seminar with Swim Smooth @Challenge Stadium with Paul Newsome/ Adam Young? I'm working hard to learn how to swim and hope to become a strong open water triathlete!!!
