Does anyone know if the 8 comes with a red-line buzzer or rev limiter? or both perhaps?

 

Both. I heard the buzzer, which is more of a beep sound in a hotlap video from the 3rotorrx7.com site.

 

yup...
the buzzer starts at 8500 i think, and the fuel cut is somewhere around 9500-10k rpm...

 

I think the media get the 8500 rpm buzzer confused with the 9000 rpm redline. Several articles state 8500 redline and imply that the s2k's redline is higher -- which is of course false.

 

fuel cut. Excellent! My Cosmo had a limiter that cut off the ignition. The problem was that it would jolt back to life when the revs went down, not fun and probably not healthy for the engine. My 85 GS has the buzzer which I like to call the "weeee we're have'n fun now" buzzer.

 

:D yup!! even in the video of buddy takin' the RX-8 'round the track at Laguna Seca, you still see him shift WELL into the redline...

 

Yup! Rotaries thrive and survive on high revs! The redline on my GS is 7k but I know guys that rev 'em up to 8k and they're just fine. My stock Nikki doesn't give me much after 7 so I don't bother.

 

theoretically, the redline could be at like 20000 without a problem right?

ofcourse theres that e-shaft thing i heard about and flexing and screwing the whole thing up so it needs a somewhat more sane limit.

Uh, no. The loads on the stationary gears increase exponentially with revs, and the curve is almost vertical much past 10,000 rpm. (This from a technical paper presented to the SAE by Kenichi Yamamoto of Mazda some years ago.)

In order to have obtained a safe working limit of 10,000 rpm, Mazda must have done some serious lightning in the rotor department, or discovered some wonderful new strengthening process for the stationary gears (or both). But 20,000 rpm is still a long way off.
