Has anyone ever heard of these things? I have tried doing a little research and all i have found is about it being on a motor bike.

I have an idea, but im would need a dead 12A, or 13B so if anyone has either of them, (They could have dead seals of for now, just want to try a prototype..)

Im curios as to making my own, im not to sure, how i would go about that.. but if i do attempt this, i would post pictures of course.

Let me know what u guys would think about the idea??? Just think about it, would it not be cool to have your car powered buy a turbocharger that is that same as your engine.!

i don't believe you could turn a 12a/13b in to an actual supercharger. ??? i'm actually kind of lost as to what you are talking about. i know the rotary was originally created as a form of a supercharger, but it's nothing like the engine in our cars.

Why not, it looks pretty simple....cut down the excenteric shaft, to one rotor, set up a gear of some sort to sipn it.....then youll have it sucking and blowing, and then its just a matter of directing the 2, sure it would be giant, but then u machein it smaller and fine tune it. I think that it is possible.. and might be fairly simple with a metal lather...and welder.

lol :P i still say it could be done

mooseknuckle

its a lathe not a lather

let me get my hand sawer and my hammerer and my torcher

No.

revhead your too funny

nothingbutrotor

don't be such a dick

And it probably could be done, but it would take A LOT of time, and probably A LOT of money.

With the todays superchargers running so efficent theres no point inless you want to make it for kicks.

I agree with Marek. Twin screw superchargers are great!

Why re-invent the wheel?

DAVID GRIMES

and don't forget your plasma cutterer and your angle grinderer and for God's sake your stinky wheel well water siphonerer.

BTW... is a moose knuckle anything like a camel toe ?

Sterling

What noone's telling you is that we've all spent hours discussing these sorts of ideas for superchargers...everything from using the air pumps to using the AC pumps to using single 12a rotor assemblies.

zduford

well thanks for the input there, none the less it was comiKal!!!!:P

A "moose knuckle" is when a man wears his pants or shorts too tight or too high on the waist like Steve Erckle and you are able to see his ***** bludge out. I suggest that you stand up where you are at and grab ahold of your button and pull your pants, shorts, underwear, etc.. up and look down at your very own "moose knuckle" !!!! Now go show all your friends your newly learned lingo!

"And it probably could be done, but it would take A LOT of time, and probably A LOT of money."

That is true, and it would also take a lot of skill and brains, but it would still be a bad idea. I always have the feeling that people who come up with these silly ideas have never actually designed or fabricated anything, and somehow they just can't comprehend what is involved in a serious engineering project.

There are turbochargers and superchargers readily available for your Mazda rotary, developed at great expense and with a lot of trial and error. The best ones are the ones developed by Mazda, and even they can be a pain in the *** over time.

If you will note, the latest engine, the Renesis in the RX-8, is normally aspirated. The folks at Mazda have learned something from all these years of screwing with compressors.

Over here we call it "the frog eyes". lol

Wow thats fitting!!! Never thought of that one ima use it on my buddies tomorrow in lab and see what they say. We are cutting up the frog so it will be a real hoot!!!

yeah, just like why would you wanna re-invent an internal combustion engine.....?

but Dr. Wankel DID and I think we can all thank him for that.

ps. not that i think this is a good idea... but its good to think different.
a rotary-style supercharger could work, but so could a piston-engine style one, but neither makes any sense. an engine is an engine and a compressor is a compressor. an engine has 4 cycles (as everyone knows) intake, compression, combustion, and exhaust. what goes into an engine is compressed, but then allowed to expand (during combustion). this is pointless for something designed just to compress air. a compressor really only has, and needs, one cycle (it takes in, compresses and puts out air all at the same time in one rotational movement).

why complicate things?

nothingbutrotor

But you have to agree that it would be awfully cool to be able to say "I made a supercharger out of a rotary engine."

Manntis

Rotaries were originally conceived as compressors, not internal combustion engines. Wankel's innovation was to use the compression to ignite a fuel mixture and power the e-shaft - making it into an engine, not a pump.

inuissus_cendi

oh yeah, defenitely. i'm all for crazy projects... makin **** out of other ****.

i'm just sayin theres no real logic in it so I dont want anyone to get their hopes up of using somethin like this to an actual advantage.


edit:

and yeah the first idea was for a compressor, but a 12a engine is not designed the same as those rotary compressors.

smnc

Fair enough, but the difference is that the Piston is a POOR design for an engine.
It requires a conversion of transverse (back and forth) motion into rotational motion.
This introduces a huge number of problems.

The rotary is better, but has it's own problems as well.

On the other hand, the twin screw eaton/lysholm-type is an EXCELLENT type of supercharger. It really has no major drawbacks (at least none that don't exist in all bossted applications).

So let me re-state it this way:
Is the wheel sucks, by all means, re-invent it.
But if the wheel is excellent, why bother?

What about the Tesla supercharger? Now, that would be a great idea!!! Quick, somebody build me one!!!
