LOW HORSEPOWER and MAZDA'S RESPONSE
I read a lot of threads saying that the Mazda's are not producing the horsepower they are suppse to produce. So I called into mazda's customer service and asked them about this, their number is 1800 222 5500. I asked for an explaination or if they have heard anything concerning this happening, they replied "no, the RX8 are suppose to be doing 238 horsepower. If not bring it back to the dealer and they will fix it up."
Since so many RX8 owners are complaining that the only get 180 hp, why don;t you guys try to send the car back to the dealer and see what they will do?

Think all you guys going around dynoing your cars should read this.
So dynoing a 8 is kind of pointless because the ECU goes into a touble code mode and the car wont make full power!
Thought I would point this out.

A bare motor on the dyno with aftermarket fuel injection is sensible enough, but the factory computer makes anything power related quite challenging.
I will probably get a big flame war started with this one, but this car will not dyno properly without the front wheels spinning. I spent an evening scouring the service manual, and there are pages of error codes caused by anything from a sensor reading being out of range, to a forced power reduction mode based on calculated catalytic converter core temperature.
This car is a rolling computer, and it is not thrilled with full throttle high rpm operation while sitting still.
The air fuel ratio will be rich, and the timing will be retarded. It's kind of like removing the speedometer cable from your TII. The car goes nasty rich and doesn't make any power.
For those that are wondering, the next article will probably be about the renesis engine. I need to do a lot more testing before that can happen though, and the sponsor/customer of the supercharged engine project has asked that no specific information be made public. Kind of a bummer for me, but not uncommon in this type of situation.
