1) When I was running up 1st gear once, I never heard the beep. No biggie. I think it may beep depending on how hard you are pushing toward redline. Also, if the radio is to loud, the beep is hard to hear. When I first got the car, if I hit red, I could hear the beep. Now I barely hear it.
2) The beep is not indicative of the fuel cutoff. The engine WILL stop pumping fuel before it gets to dangerous RPM levels. Shift at the beep, but if you hit the fuel cut off, don't worry too much. The fuel stops pumping to keep you from damaging the engine. Granted, you don't want to do this alot, but you won't hurt much if you do hit it.
3) LISTEN to your engine. You should HEAR when to shift. My dad, definitely of the old muscle car tradition, thinks tachs are dumb because you are supposed to listen when to shift until you know your car enough to FEEL when to shift. I agree with this to a point: when you FIRST get a car, visual/audible shift-time clues help the learning curve.
My suggestion to you is to not worry but look at your RPMs and shift before 9500 until you recognize the sound of 9500, then shift when you hear that sound. The beep is not reliable at all times, and the fuel cut-off will keep you from destroying your engine.

The fuel cut off is around 9.5k rpm... if ur car is going past that then you may want to be concerned.
As far as the beeping noise goes... ild suggest taking it to the dealer to get checked out.

Keep pressing on it and see if the needle bounces up and down after 9000 rpm :D
I can hear the 1st gear beep, but only for a split second coz it goes to redline too fast that I have to shift up immediately. 2nd and 3rd give me longer beeps though.

wow, you guys need to bag on your cars a little harder, try driving it l;ike it was stolen, you might have some fun, since 1000 km I hit my redline 10 times a day. it is fine on the motor. The renesis motor does not take on damage until at least 12,000 rpm in tests. The car only redlines at 9k because the tranny can not take a hard shift at any higher.even there, mazda is only being very conservative. fuel cuts off at somewhere around 10 or 10.5k. I have constantly power shifted at 10k with no problems. You guys need to let loose on your vehicles a little more, you might have some fun.

a) you probably just didn't hear the beep because of the radio/exhaust/wind noise
b) the tach is off by about 500 rpms near redline... so you have to go a good deal past the beep and past the indicated redline before the fuel cutoff will actually kick in

and if you exceded the redline wouldn't it be the manufacturer's fault unless they can prove you removed the rev limiter.

There is no way they can bag your warranty because you've been bouncing off the rev limiter...that's what the limiter is for, preventing you from damaging your motor by over-reving it!

Saying that it is the company's fault for allowing you to exceed redline (thus absolving you of any wrongdoing) is just as irresponsible and immature as telling a police officer that it's Mazda's fault for letting you do 140mph in a 65 zone (they should have had a speed limiter at the legal speed limit, eerily reminiscent of your argument that they should have had a rev limiter at redline if they didn't want you revving above that point), so they should go after Mazda for the speeding ticket, not you. It's just as bad as blaming Mazda for allowing the Renesis to be over revved when you misshift in to first instead of third at sixty mph and saying that they should be the ones that pay for your error. It's just as bad as blaming Mazda for your fragged differential because they allowed you to rev up to 8000rpm and dump your clutch. It's just as bad as blaming the car that you hit in an intersection for the accident even though you were the one that tried to beat the red light ("If they had looked both ways before taking off, they would've seen me and waited for me to go through"). There are many more situations that I could go in to to show you how rediculous blaming someone else for your own stupidity is, but I think that I've made my point by now. People are allowed to do (meaning are not physically prevented from doing) a lot of things that are bad (such as murder, theft, injuring themselves, etc.) and have no one to blame but themselves when they are faced with the consequences of their actions. However, this does not stop them from placing responsibility for their actions on everyone from their parents to corporations to space aliens. Personal responsibility is a good thing, believe it or not, and we as a society would be much better off if people actually admitted that they can make their own decisions, rather than always looking for someone else to blame when things go wrong.

social problems == red line == rev limiter == voided warranty
WOW
the rev limiter is there to protect your car you will not damage the car if you bounce it a couple of times.
well neither of us work for mazda or has done this to our car so with no real world experience we just have different opinions with no knowledge to back it up.
i doubt you can back up any claim that 9001 rpms is bad for your car.

wow, do you honestly think they could actually void your warrantee on a issue like this when they won't void warrantee's on trannies where it is obvious the guy has been dropping the clutch and bagging it out.
think about it. why would they open that can of worms, when it is easier to just lower the rev limiter. It is common sense, So start driving your 8's like they were meant to be driven, you never know, you migyht develop some testicular fortitude.

Good grief, excellent morph from warranty question to sermon on personal responsibility. By all means, shift at 5K, max. You know, just to be safe

Cliff Notes for my last few posts: Revving up to 9000 and beyond probably won't hurt your engine, but if something does go wrong because of sustained rpm levels past redline it is not Mazda's fault, it's your own. Therefore, they would be legally justified (which is what was being questioned in the first place) in not covering such work under a standard warrantee.

beep beep beep beep. beeeeeppppppp
I am only expressing frustration due to people that buy a sports car and don't ever really enjoy it as much as they should because they are afraid that they might wreck it. Mazda is responsible for putting a rev limiter in to protect the motor, so have at er. And buddy, there is no way mazda would win in court, it has been proven in the past. yah, you put your car into a pole or drop the clutch and snap the train it is your fault, but by all means men, drop your ***** and rev that motor.
Moral of the story is, don't be scared, drive that car like it was stolen. Get it sideways at 160 mph. Power shift at 9500, show those 5 litres what a rotary is capable of when driven properly. believe me it is a lot of fun and you won't regret it.

Why rev to redline
I don't see any point to revving to redline in the RX8. I can feel and more-less confirmed with a G-tech that power drops off above ~6500, so there is no point in revving higher. I wish our engines made power up to 9k like they should.
In my view there is no point in having an engine that revvs to 9k if you stop making power at 2/3 of that.
Just out of curiosity has anyone called Mazda to ask why the engine stops making power at 6500 and then the dyno charts confirm that the performance goes to crap?
