Ok Someone in Prince Albert City of 40,000 and me being one of the ONLY REX entusiasts i heard of someone bragging that they have a six rotor engine that produces arround 500hp that is the way he baught it from BC... apparently it is a race car engine... he claims that the engine is smaller than mine and the rotors are rogghly 1/3 the size of mine... now can somone collaborate his claims... or is he just bs'ing all the way?

 

6 rotor with 500HP sounds like bullshit, not possible,a 4 rotor makes more than that ,well what do i know

 

yes but take a look at this web site! and take a look at the pictures!

but i sincerely dought he baught that for what he said he did!

 

i got to see that **** to believe it

 

crazyness...though those that doesnt look like it'd have rotors 1/3 the size of ours. lookit the alternator on top of it for size comparison.

 

if you click on the link for 900 BHP Hurley Six Rotor Engine Seeing is Believing ! you'll notice the top of the page says "DREAM PAGE" the guy is full of ****

 

i did catch that,he is so out of his mind

 

 

I believe the folks at Granny's Speed shop in Washington State made a 6-rotor motor that they were using some time ago in a dirt-track stock car. Its on their web site, you'll find it if you poke around. I don't have time this morning to go find it, though, sorry!

 

From a technical point of view, there is nothing to stop you from building a 6-rotor... hell, even a 12 rotor engine. You'd have to manufacture a few custom parts (the eccentric shaft comes to mind ), but it's possible. Now whether you could actually use it in a working application, well that's a whole other ball game. Just needs LOTS of money, and the attitude that you CAN get it to work (even if it will take years ).

 

The eccentric shaft flexing is a problem when going with that many rotors........

 

Ha! I had a dream like that, then I woke up in a mess. This is about the craziest I've heard lately, that is real.
There was another 4 rotor at sevenstock that they are going to throw in an fd w/ big single. He didn't sound very confident about the engine however. https://www.rx7club.com/forum/showth...hreadid=117228

 

The link above is the fd engine, the pic is a 4 rotor from an airplane. The guy cast his own int. housings fgrom aluminum for the av. engine.

 

Good old saying well i just say it but it goes like this MORE ROTORS MORE PROBLEMS

 

It is a good possiblity that they either used 10a or 12a parts....hummmmm

 

sounds like **** to me. There's more to it than just bolting two 20b's. The reciprocating mass alone raises some isssues.

 

iv never heard of the e-shaft flexing being a problem on rotary engines. Since our e-shafts are so damn strong compaired to a crankshaft. Its unreal. I dont think even 6 rotors would cause a big problem. But can you think of what you gas mileage would be? youd probaly get 8mpg on the highway!

 

Yup, e-shafts flex!
Just look at the 26B, there is more to it than just a pair of 13B's stuck together... they built a special intermediate housing to accomodate double bearings to compensate for flex in the the e-shaft... any larger than 3 and your gonna start having 'issues' with it... hell, the 3's may have that problem too!

 

yeah well that is what i thaught that there would be problems with a six rotor! however in theory if the rotors were infact 1/3 the size then you would be looking at 1/3 the reciprocating mass theorfor if you had a good eccentric shaft then it coult "possibly" be done! however i think the guy is bssing! but i will ask him to see it! then we will se how much bull **** he sleeps and bathes in hell by the sounds of it he even eats the ****!

 

The three's have less of a problem, since the second intermediate housing incorporates a stationary gear and an intermediate bearing, hence the use of a two piece e-shaft.

e-shaft flex is pretty much eliminated with the guru racing flex kit. Just make one of those for a six rotor, there would be almost no flex... provided you could find a someone to balance that monster of an E-shaft.

 

Oops, my bad, it was a 4 rotor...
