stock V8's redline at 8k? LOL dude, I've never seen a camaro redline over 6500... my friends 96 Z28 redlines a5 either 5200 or 5500 I can't remember exactly, my other friends 86 is about the same, and another guy I know(not exactly a friend lol) has a late 60's Z28 that redlines at 6500 I believe... maybe they can rev to 8k and not blow, but wow, a 13B NA can rev to 10k for 10 minutes straight on one rotor before it goes... theres a video around here somewhere of some idiots doing it

I hit 8800 on my stock motor all the time..

Man, you need to actually do some research. Check out the '67-69 Chevy DZ302. A 4" bore and a 3" stroke, designed specifically for high rpms. Yes, the factory marked redline was 6500, but the engine itself was plenty capable of 8000 rpom in stock form, and 9000 rpm all day long with very minor mods. I've built an engine like that for a car of mine, and there were 5 of those Camaro's autocrossing in my sports car club.

Where you get off thinking that they have anything to do with a modern 350 cid engine is anyone's guess.

Now, I have yet to see a 13B in stock form rev past 7500, and Iv'e yet to see a streetable 13B go to 10. And 1ok on one rotor? Not going to move a car very well doing that. 10 minuted before it blows? Not very reliable.

Sory, been working with rotaries for way too long to be fooled by that stuff. I've dealt with rotaries that could twist well over 10k rpm in race form. I know whow long they last, and how driveable they are. I've been doing this for a couple decades, my friend.

any rotary on one rotor isn't gonna work very well, and holding the car at 10k+ rpms for 10 minutes is pretty freaking good... how can you say you've never seen a 13B rev past 7500? they redline at 8000, they can rev plenty higher, theres just no reason to

If you've been working with rotaries for so long, then you should know what a stock form rotary can do. True, a stock rotary motor won't last long revving 8000+ rpms but what motor can in stock trim? If you studied Wankel's concept of the motor, the rotary motor is the most mechanically efficient motor design ever made. Minimal friction and moving parts made to rev VERY HIGH. The only problem is heat. HEat is a adversary for all of us. But what piston motor do you see can rev as high as a rotary? I'd like to see one.

BTW Soyo, I have that video you're talking about. Its a guy name Brandon and his friend. They bought a S5 convertible with a blown apex'i seal and revved the sucker to hell. They wanted to see what would happen since they were doing a turbo swap anyways. If I remember correctly, they held the motor at 9000rpms for 9 minutes and 45 seconds, and they HAD to stop because the exhaust flared up near the gas tank and could have caused a nasty fire. I'm sure that motor was warped into the next dimension.
