Where's the redline on an RX-8?

Hey guys,
I'm guessing its somewhere in the 8-9k range because it's rotary, does that sound right?
Thanks!
Andrew

power drops off at 8800 and beeps at you around 9000 with a cut at 9500 or so. The tach is a little off by then, so your results may very. I never really look to be honest, I just shift when it beeps at me which is at least once a day.

for all intents and purposes 9000.

Remarkable, thats I know Porsche is able to get 8,250 out of its 3.8 in the GT3, and Audi 8,250 from the RS4 V8, but this from a Mazda is astonishing.

Fuel cutoff is at 9,000 RPM. The tachometer gets optimistic at high RPM if you're accelerating fast. I saw it hit 10,000 one evening on my way home from work when I merged on the expressway in third gear and freaked out until I did some checking and found that it's a known issue that the tach goes too fast under hard acceleration at high RPM.

10k, WOW!!!!

The Rene could handle even higher rpms than that, but power starts to drops off drastically around 9k, and the tranny can't handle a lot more than that. Also the Tacho is not only over zealous at high rpm, it reads three hundred rpm higher than it really is to start.

There is a vid on youtube somewhere of Charles Hill's (of BHR fame) 8 burrying the RPM gauge on a dyno after he removed the fuel cut. I would guess he gets it to 10.5k or so. It just keeps reving forever. Video is embeded in this post.

The video here is interesting too.

Years ago there was a company called Rotary Engineering. They had a modified 13B they called the Turbo Alternative, guaranteed to produce at least 225hp. It could also be revved to 10,000 rpm safely, but they had installed hardened stationary gears and locked the gears into the rotors to prevent them walking out at high speeds. Rotaries can rev forever with the right modifications. And they sound great when doing so.
