i know rotary engines are used in airplanes...has anyone ever heard of getting a bigger one...like a 2.5 liter rotary and try putting it in a car??? if anyone has heard anything liek this from anywhere please describe best you can

 

do a search on "20b" and "26b". Those are the codes for the three and four rotor engines. the 20b came in the Cosmo over in japan

 

i know about the cosmo but that is way to expensive i mean getting an engine from a airplane junkayrd or something...or am i totally off base with this crazy idea??

 

yup you are completely insane.

 

hahaha i see...so there is no way that would work???

 

YOu can do anything for the $$$$$$ but I think it would be easier to get a 20B or get some huge turbos

 

the only rotary engines that are in planes are in expermental planes, like home builds (Vans aircraft's RV series is a really popular platform for the wankel.) And since putting rotorys in planes is a new idea, there wont be any in a junk yard. Also, they are all flying Mazda 13b's. And theres really nothing different from the aircraft engine VS the ones in our cars. Powersport makes one thats got a small PP with an intake thats designed for a very specfic RPM. It makes some great power at a low RPM, and could possibly be streetable, but they want huge cash for 'their' engine.

if you wanted a true bigger engine, you would have to find one of those super rare experimental chevy rotarys. Even if you found one (some guy on this fourm got rotors from one) it would be a crime to run somthing that belongs in a museum. The engine was huge at 3.3L
it was a 4 rotor i believe.

Maybe I'm just talkin crazy, but wouldn't you have problems with trying to line up an engine with larger rotors to the transmission? eg. larger rotor = larger diameter = won't sit as low as the original = won't line up with tranny. Not to mention it may not fit in the engine bay at all.

 

wow that is some wicked good info OC where did you find all of that out??? but it makes sense i thought that rotary engines were in ude in airplanes for a long time...but i guess that is turbine engines huh, oh well

 

They've used them in airplanes for a while, except as OC stated, they're built for a specific constant RPM, so there powerband isn't designed for a street car. Check out the skycar and other designs by them (just search google for it) I want one of those!

 

hmm i see now...so they are made for a constant speed, wow i learn something new on this forum everyday. well i guess its back to my good ole 13b n/a. there goes my dream down the drain , boohoo hahah j/k

 

Uh guys, the "rotary" engine in a plane is a piston engine. Hit any of the aviation websites and you will quickly see what I mean.

 

radial engine? yes its a piston engine, but I think they are planes with wankels in them.

 

aaron please xplain what you mean im very confused by your last statement hahaha

 

Here you go!

 

I want I want I want

 

wow!!! thats huge!!!!

 

haha... time for a rear engined 7 if it will fit... plus you would have to get a kit to raise it with.

 

Aaron: those radial engines (sometimes called rotory) are used in most, but there's quite a few that actually use wankel's rotor design. Most commonly for craft that hovers.

 

WOW, please tell me that's photoshopped... if not, what is it?

 

I'm well aware of that, but it is my impression that the original poster was confused between a radial piston engine and a wankel rotary engine. It is a VERY common thing to be confused with.

Kai: Yes, that is a real engine.

 

where did that pic come from. i come from a family of pilots and i need to know about that engine
is that a Curtis Write engine?

that monito site has some info on some wankel airplane engines, but nothing much.

 

That engine is not an airplane engine. It is an experimental industrial engine (if I recall correctly).

 

There is a rotary engine that is made with pistons althaugh very rarely used, they were used very rarely in WWI, as the setup of the radial was verry similar but instad of radial cranking a shaft on the rotary piston the crank shaft stayed the same and the pistons turned arround it. I think this is what Aaron might have been speaking of!

 

man what the hell, the forum ate my post too! eh... gay.
