Hello My name is Paul and I write from Europe.
I apologize in advance for my bad English and for the slow reply, but I hope to make me understand.
I decided to subscribe to this forum because I'm about to make a major purchase and I need the opinion of some of you.
I am very willing to buy the supercharger kit and the kit re-cal PettitRacing.
For this I ask you all to write down everything that you can tell by Pettit.
How much power have earned your cars?
Qanta speed?
Have you ever had technical problems with this kit?
What are the differences between your rx8 and those turbo of your friends?
Use the radiators which provides Pettit? Or you have purchased a better performance?
What are their technical assistance, and the tuning of the map?
No matter if in the remaining parts of your car is stock or heavily modified, I am interested in all your opinions and testimonials.
I hope you help me not to throw away my money.

I thank everyone in advance

Paul

 

Where are you from? There's a lot of information on this board already and an UK distributor for Pettit products that may help you.
The tuning they offer is a generic map, buying a tuning device and have a tuner work a specific map is a good starting point after the install.

Since you live in europe you probably didn't do the right maintenance to the car so starting from a thorough check up would be a smart move before spending a lot of money.

Many pettit owners will join and offer the specific advice you asked for

 

my car is already in pieces!! 're quiet!
I really want to hear the voice of those who tried!
You are one of these?

etc.

 

I'd rather go turbo instead but their system works as intended: noticeable increase in power etc. It's not really plug and play since a custom tune and some little supporting mods would be required for peace of mind but it's close to being so.
Who is rebuilding your car?
Jeff is right anyway, you should read some of the threads concerning it and its alternatives.

 

Because if you are not familiar with the language, never find what you are looking for
Anyway, thanks!
I respond to BSE: I modify the car, as I always did, but I never changed the maps.

 

I was thinking more about checking the compression, the ignition system and all the ancillaries before spending a lot of money.
Language is no barrier, we always find a way to understand each other... kinda
