i've been hearing lately in magazines, on the forum and elsewhere about people that have rotary engines reving to like 12k rpm... what gives? what am i missing here? what do you have to do to have a screemer like that?

It can be done, but it takes engine oil porting.

First Lesson: Stop believing everything you read on the internet and in the (usually) grossly inaccurate magazines.

There is no point to revving that high for a street-driven car. You will need a huge turbo and/or peripheral/bridge porting to even come close to making good power at rpms that high.

Also, to achieve a 12k rpm, be prepared to lose all power below 4500 rpm and to have a 2k rpm idle...

i don't believe everything i hear or read, hence, the post. i'm not saying i'm interested in doing it, just trying to learn something new. i figure, if i learn something everyday, i can't possibly forget it all next time i'm drunk

What is the redline? 8k rpm.

8000rpm is what Mazda lists but the tach is red dashed 7500-8000 rpm.

A stock car usually doesn't make much power past 6800rpm or so. As you do bolt-ons power continues up closer to the 8000rpm redline.

The rev limiter will kick in around 8200-8300 rpm.

Unless you're running a peripheral port there is no reason to even bother turning that much RPM.

These amps go to 11...

hmm a thought just occured to me. If with certain porting your idle becomes 2k rpm ish~ what do you do when you move from a dead stop? burn the **** outta your clutch ? its like holding the RPMs to 2k and moving.

That's why you don't use it on a street car.

You typically dump the clutch and go. In a race situation this only happens once (hopefully).

DamonB

Nope. You don't slip the clutch, you slip the tires
