rev limiter

I know they don't have a gear ratio suited for racing, which is why a rev limiter would help in that type of situation where you can bounce off the rev limiter instead of engine brake early.

a rotary engine can take it.. its not piston bullshit so just drive the car geezus.... you arent in the same piston game as everyone else the engines dont care... dont cruise around at 8000 rpm and youll be fine .....

WTF are you talking about? Every RX-7 in good working order has a rev limiter, and most of them are 1000 rpms above redline.

Nothing is going to stop someone from over-revving from a botched downshift... a rev limiter will prevent you from doing any more damage than you've already done, though.
Of course, for the most part you can't downshift more than one gear at a time or so at high rpms, because the synchros won't always let you do it (don't try this).

hmm mazda put it this way for a reason. because it can tolerate it.. not a piston engine.. new game.... piston engines fail cuz the valvetrain alot of the times.. tooo much crap to move at once... someone should close this thread it. crying about revs is retarded. no rev limiter in the world is going to stop your engine from spinning over the rev limiter if you go in too low of a gear....12,000 rpm in 1st gear created by a retarded downshift is still going to be that 12,000 rpm turned by the momentum of the car moving forward.....(theoretically speaking) "cry me a river" stop typing stupid crap and go enjoy your cars:-P worry warts

My car puffs out white smoke if I rev it over 8000. And nowhere in this thread did anyone mention downshifting at too fast of a vehicle speed (where the lower gear would be at over 8k). The problem is simply hearing that annoying buzzer when revving over redline on accident. No power is made after 8000 so there is no reason to go past that anyway, so a rev limit at 8k would be favorable.

Then don't rev it over 8k.
It was mentioned earlier, IIRC.
If I blow an upshift high enough in the rev range to take the engine over 8k, then I would think that the first thing I would notice is the the fact that the back end now wants to go in an entirely different direction than intended. A lower rev limiter would not do squat here - your engine is not whats causing the overreving.
As was pointed out by several people, the motor won't be hurt by the occasional rev past 8k and for auto-x or track situations the ability to stretch out a few extra revs (like at the end of a straight when you will be braking soon and would lose time with an upshift) is a very useful thing.
