What does a Wankel sound like?

[Prince Valiant]

Unreal.

This is a 4 rotor producing 590hp...I don't know the times it runs, but as you can tell, it gets up and goes.

IMO, I am not a big fan of the idle sounds....but if you like watching the Indy cars at the mile then you'll love it as I do:

4Rotor RX-7 (http://goku.unixpimps.net/~brandon/4rotorfd.MPG) yes...some may have seen it before, oh well.

[SMS 1]

That is BITCHIN! :rockwoot:

[Flight_740]

I wonder how it sounds in person.

[DocDave]

That is wild sounding. It looks like alot more than 590 going down the track! :wow

[Snowseeker]

WOW! That has got to be the coolest thing I have heard and seen in awhile!!

How do you up compression on a rotory?

[Flight_740]

Now is Mr. Wankel the guy that invented the Rotary and than sold it to mazda? If im not mistaken , he couldnt get it to be perfect but he got it to work than became a fine tuner for mazda. Is this correct info?

[jbiscuit]

thats insane. That thing sounds so bad-ass!

[BAD LS1]

Sounds like an electric shaver during a power surge:confused

[BadAzzGTA89]

Who can tell me the brand of car the wankel came in i seen one at a BMW dealer in iowa a few weeks back!

[Flight_740]

I think it was just Mazda

[BadAzzGTA89]

Nope wrong

[BAD LS1]

Yeah BMW's only run I-6's V8's and some V-12's... never any maximus-noisyest rotary's

[BadAzzGTA89]

It's not a bmw i said i seen it at a dealer and it is older!!!

[BAD LS1]

What is this... Wankel trivial pursuit???

Might as well spill the beans to the OTHER inquiring minds that want to know....

[BAD LS1]

Oh **** !! wait!! i know what it is !!!!

A 1974 Arctic Cat Panther snowmobile with the Rotoary engine option????:banana :Hump

[SSmike1]

sounded like a SCREAMIN ME-ME

wow, high pitched HP.

did you notice how long it took him to shift?

way to long for drag racing!!!!!!!

sounded & looked like some good HP,
but
nothing like good old AMERICAN V-8 HP

:3gears:

[jbiscuit]

That good old AMERICAN HP looks like it would get walked by that Mazda....that thing rips!

[BAD LS1]

Fast for an electric shaver:goof

Mazda put Wankels in the Cosmo, RX2, Rx3, REPU-rotary engine pick-up, RX4, RX5- also known as Cosmo, RX7, and now RX8. They skipped "RX6" because it was hard to pronounce in Japanese.

IMHO, wankels are great when they are in good shape, but they can become a pile of scrap very fast. They are not as rebuildable as a common engine without replacing expensive parts. Some parts can be remachined by specialized shops, but most often they are beyond repair.

In the 70's Mazda cars, the Wankel had a ton of emissions controls. An air pump, vacuum solenoids, and relays cluttered the otherwise simple engines. They also had an exhaust chamber to burn excess fuel. The carburetors were overjetted to keep this "thermal reactor" lit. Fuel injection solved most of the emissions problems.

They also had oil injection like a two cycle engine. The problem was that they used motor oil from the engine and injected it into the carb. Adding oil to the engine when filling the gas tank was common. For racing, this system could be disconnected and a better quality two cycle oil could be premixed with the gasoline.

I have owned a few Wankels over the years, a 74 RX4, 78 Cosmo, 70 Arctic Cat Panther sled, and a Arctic Cat "Grass Cat" lawnmower. Add to that the many books, magazines, model cars, and model engines.

Can you say, "Wankel Nerd"? :yawn:

I watched it again.. I love that thing

[indyzmike]

I know they scream loud enough to drill your eardrums at high rpm but I am amazed at how it sounds at idle. I love it!
