I was just wondering... if you misshift into a gear and end up revving your engine up to 10k or higher, even for like a second, will it mess up the rotary engine? If so, how? I'm still not really familiar with rotaries and just became curious what would happen in a rotary engine when over-revved

Did you actually hit 10,000?

Rookie84

No, I was just wondering :-p

the flywheel would fly apart before the motor

Probably nothing would happen, download the rotary pop video that was posted earlier today. 2 guys ran a rotory for 7 minutes at 9K while the coolent bubbled out of the engine. It took 7 minutes of over revving to kill it!

I saw that vid... it was pretty insane...

I wonder why someone would do that...

But if it was loosing coolant all that time, I would think that it is overheating that killed it and not over-revving.

Rookie84

I would think so too since the engine blow started fire. If it was killed by over-revving, then it's not likely that there will be fire IMO.

I liked the nice glowing exhause manifold.

when i got my first rx7 (first manual car) i was getting onto the highway and shifting into 4th and accidently went into 2nd.. musta been right at the extent of 2nd gear.. woo my rpms shot up.. "BEEEEEP" needless to say.. rotaries are lovely about RPM's

RamCon

that RX-7 pop video I bet the engine was well above 9000RPM...the tach just buried iteself at 9k.

I did it once mishift from 4th into 2nd for about 3 sec and it over-rev. I thought I blew my motor or something, but nuttin happen that I'm aware of.

chiefnobum

it doesn't hurt a rotary to rev it to fast because it doesn't have the up and down motion of a piston engine that kills it, it just goes round and round and there is no stopping, so by design I think the engine could take an almost unlimited amount of revving, it's the other parts that would get killed

venomrx7

The reason that they did that in the movie is taht the ingine was already half blown and they were finshing it off. ONE ROTOR GONE AND IT STILL LASTED THAT LONG!!!!!!

i believe at one time my friend showed me this one rotary racing engine that idled at 8K and had a redline of 21 or 22K ...it was insane

Thread almost at the bottom has a link to the video. Something like "who popped this engine"

Here's a link to the video:

that just goes to show you how bad our rotaries are

nathantheman

as far as i have heard the rotary itself is very resistant to high rpms. if you over rev an car your gonna have problems, but rotaries could probly handle the most. heat seems to be the main killer of rotaries. that vid with the 9,000 rpm+ for 8 min or whatever is nuts, imagine how long that one rotar would have lasted, if they hadn't left the coolant top off.

RylAssassin

Wait a minute how the hell is he going to rev to 10k if all of our cars have rev limiters?? I mean its not even possible. Right??
What series Rx7 do you have?

nathantheman

the cars have revlimiters that keep them from overreving under their own power, but it is still possible to overrev them via transmission force, if your at 7,000 in third and u shift to 2 you will be at- 7,700 i think, even if your engine rev limiter was set to 7,100

From what I understand the engine can take it. The things that can go wrong are.
Flywheel/clutch breaking apart tearing your legs off and not enough oil for lubrication at sustained RPM's

Louis M

chiming in about FD's... GoodfellasFD3S overreved his to over 11k one time and his engine was perfect... i just remember that post

ohh yea the one where he has the pic of his powerFC showing the RPMs? hah
