Is 11000+ rpm's safe for your engine
#1
Yeah, so I just picked up a used 2005 RX8 2 weeks ago. My supervisor at work wanted to race me because I've been getting a lot of props for my car. So he brought in his 2001 Ford Mustang GT Bullitt collector car in to race me after work. I've never raced a day in my life, yet I accepted.
On the second run I messed up bad and took my engine to maybe 11000 rpms after missing second gear completly. Now I fear for the life of my engine because maybe it's all in my head but the engine just doesn't sound right to me. I'm hearing ticking noises that I haven't heard before and the engine seem to shake a little more than usual when it idles. But it could all be in my head. Please tell me it really is safe for rotaries to rev to 15000+ rpms.
Just in case you wanted to know, I lost the first run too, by about 3 car lenghts.

It's usually not as bad to redline(or dip into it) a rotary compared to a conventional piston engine. Actually, some may say, "A redline a day is good for it." I constantly overrev my 13B but that's only to about 7250-7500. In your case, the rx8 redlines at what....9K. Now I dont' know much about rx8's but don't they have a fuel cut-out or rev limiter on the top end? I dont' think your motor would be able to rev to 11k but maybe 10K...I dunno..I'm speculating. In regards to it being safe for rotaries to spin to 15k+, they have to be built properly to withstand that much force. Your car is probably okay since overreving isn't that big of a deal.

yes, in the rx8 (and probably all cars made today) there is a rev limiter to protect your limit. In an rx8 it is 9k RPM - or if you have an auto 7500.
Also, if you are still under warranty, you might be able to have a Mazda dealer take a look at it for free.
