huh?WTF

I never heard of that. I think you own a honda or a stang. Come on stop pulling our legs you ricer. j/j

I think this would go in the lounge or at the RX8 forum.

rotorsport

yeah it seems like true cos at the auto show i asked about the release and at mazda they told it they had production problems and they dont even know if its gonna be for the this year...


its something like the apex that doesnt "seat" well and causing that compression problem...

Sure, just keep the 5/6 ports closed and slap a turbo on! That works for me!

Renesis genesis

But let’s face it, the RX-8 is all about rotary power. And the Renesis is an intriguing update of the Wankel design.

Early problems with the rotary seals have been resolved. But in developing the RX-8, Mazda faced a number of other challenges. For one thing, it had to drive down cost, one of the reasons it chose not to turbocharge the new engine.

Emissions and fuel economy were even more challenging. A major issue was the fundamental design of the valveless rotary, since for a brief interval, the rotor would leave open both the intake and exhaust ports. With the new, 2-rotor Renesis, the three exhaust ports have been moved to the side rotor housings, so they can be completely closed when the intake port is opened. That eliminates unintentional exhausting of unburnt hydrocarbons.

And earlier rotary designs tended to produce inefficient burns because they operated at lower temperatures. The Renesis has been designed to capture unburnt hydrocarbons and carry them over to the next cycle. The carmaker claims the new engine will be able to meet both the tough new Euro-4 and U.S. LEV-II emissions standards.

Hii rotorsport!!!!
I do that sometimes ago...And my trouble is there anywhere....Anytime....Specialy when a charge is apply to my rotary engine..Please HELP ME!!!!!!!

rotorsport

what are you talking abtou???

bingoboy

SCC said the ports weren't opening and that was killing off some of the car's power, but when they discovered this Mazda yanked the car out from under them so they couldn't play with it anymore.

KiyoKix

Yea, the only problem that I've ever heard of was the ports not opening after a certain use. I heard that from a few magazines.

rotorsport

i've called the local dealer and asked them about the release and they told me they were still waiting about the new date to be confirmed

The Ace

Yeah, like Mazda would wait until the last month (and especially April's 1st ) to announce/discover that the RX8 has port problems......

Come on, cannt you think of anything more creative ?

dr0x

I dont believe SCC just printed that article, plus mazda wasnt the one who even said the ports were messed up. I think C&D did mention this too.
Do you mean you are getting crankcase pressure? How did you confirm this?

Enolab

My RX-7 is always compressing in the pan specially when i'm in charge...Load...I see some yellow,brown smoke out off the hood....After that i stop the vehicle and verify the location of that smoke and it seem to be the oil pan...I think the pan have a too compression in that...Can i manke a hole in that or an evap???
Help me!!!

Did you cap the two crankcase vent lines?
