I/H/E = no gains from an RX-8
Have you ever taken a look at the exhaust in the RX-8? It's almost a complete 2 1/2 inch straight pipe, there is only one bend and when I replace the mid-pipe it has the same bend in it. In the Exhaust the only thing that will get you any power what so ever is if you replace the mid-pipe section with a catless non resonated mid-pipe. doing this will gain a maximum of 8whp (when not tuned for it) and you shoot flames out of your exhaust because the car runs super rich.
The intake actually makes you lose power. So what I did was replace the lower section of the box and added a cone filter using the top part of the box as a heat shield (works quite well too) which then by passes the restrictive part anyways which is the VFAD which only opens at certain speeds to allow more air in (so now im letting more air in anyways) and the engine sounds alot louder.
Headers are way too expensive and dont net you anymore than about 5whp. definately not worth it.
And to have the car tuned I would need a management system or a reflash from racing beat since cobb doesnt have a reflash for N/A 8's. The management system Interceptor-X would be the one to get since it can be programmed much easier and safer than say the greddy system, but it costs about 1200 new and 1000 used (no one wants to give those up for cheaper). The Reflash from Racing beat is obsolete now, with the reflash from mazda and the last rx-8's to roll out of the warehouse having a ECU that is up to date netting as much power out of the car with the stock ECU as possible. People have compared stock to the Racing beat and found no difference so why pay 300 for it?
All Im gonna do with mine is grab the mid-pipe, Mazdaspeed shocks and springs and be done with it.
I was thinking about supercharging it but they raised the price so much since they did the reflash from cobb that its not worth it anymore. 300whp for 7k? might as well pay the 9k for the turbo 400whp....
