if you did drill holes in it then what about the whole idea of 2 stroke oil being better for burning. i would rather have less carbon build up and just use premix.

 

i got it!!

 

think about it.... wait this might not work..... but anyways if instead of apex seals it was another triangle at the tip... a small one... it could be filled with oil so the engine wouldnt burn it as much... you know what im saying... ill try to draw up some pics in my free time

 

From what i understand - you mean filling something (that would essentially replace the apex seals) with oil?

But that would be a bit of a pain when you have to take apart the engine every few hundred miles or so just to refill the things.

But pinkfloyd, what does a standard rotary burn? In theory, it should be slightly MORE efficient than standard, resulting in LESS carbon, and LESS oil being used - an oil treatment could be added if you want to stop build up of crud in the engine though

 

true. this would be much better then stock. but i think premix would be better. both are good. and its great idea.

 

have a look at the hurley engineering site it appears they already put into use the idea of oil fed to the apex seals thru the rotor seen here in their drag bike which is based on a nsu engine and also a new type of 'swing tip" seals seen here

 

well, it just goes to prove the quality of our ideas then doesn't it


Any luck with the searching QuagmireMan?

 

wow they say they have a 6 rotor

 

what searching

sometimes i forget what i say

 

i think im becomming old and ...... i forgot what i was gonna say

 

6 rotor...link pleez. i could not find it on there website

 

i think you have to phone up about that 6 rotor, and even then, they can't tell you much about it

But you said you were going to try and find a few old rotors/housings to try a few of these ideas on

 

oh yea!! thanks

and as for the six rotor he told me pics were on the website... but i didnt see any

 

heres one... if i did it right

 

it was made back in the 70s in europe

 

kinda scary what kind of HP they could get out of that thing with todays technology

 

Ooooohh.....

I want, I want, I want, I want, I want, I want,



And look what carb's they're using - SU's, the same as I'm using on my 12a semi-PP. Now imagine if they done PPs on it, ceramic apex seals, fuel injection, turbo and some Renesis rotors

 

im guess with todays technology a 6 rotor N/A would put out about 800 HP then do a Quatraturbo you got yourself around 1700 HP........... i could only imagine

 

You could probably obtain 500-600 HP in street trim with that thing; and you could probably get 1200 NA HP out of a 6 rotor (assuming linear regretion) in race trim.

One thing I can't imagine are the stress forces that eccentric shaft would have to undergo. Mind boggling.

I definately love Family guy btw

 

and wiht modern technology, you could simply make an e-shaft from titanium

 

but thinking about it, if you had enough spare engines, and access to a CNC lathe, you could quite easily make a simple version of it

But it would be best to get intermediate housing bearings as well though, and limit it to N/A only (at first)

 

i am a noob still....when you say "intermediate housing bearings" you mean the E shaft is supported with a housing with bearrings between each rotor houseing.

 

On stock engines, you only get bearings on the end housings, the intermediate housing (the one in the middle)

You can get a kit from somewhere (forgotten where exactly) where you can put a bearing on the centre housing to reduce e-shaft flex at high RPM.

Now image extending the shaft by three times, now you see the point of having those extra bearings!!!(could be messy if you didn't)

 

ya thats what i thought. i was just checking

thanks.

i wonder fi any one has done this with the 20b as to my Knowledge they only have one intermediate houseing and i think they should have 2. one inbeatween each rotor. i think this only refers to me, because if i ever did a 20b or something i would do it right and use lighter rotors and have it red line at at least 12k if not more and would need that extra help as to not let hte e shaft flex at all

 

a 6 rotor!!!! oh snap! this is a great thread... im glad i started reading it again. i really like the seal floting on oil deal by hurley... that will prove to be good!

but, i actually came back to this post with another idea..haha im back! i havent read pages 4-7 so maybe this has already been discussed... but while i was asking for some advice on my 20b conversion something struck me. i was surprized by what pettit was able to do with the 20b on the STOCK turbo... the engine was originally rated at 280HP... pettit makes 550 on the same turbos. anyway, i have been thinking about a rotary miata converwion for sometime and i was thinking.... 550HP/3= ~180HP!!! how about a 1 rotor 7b turbo? 180HP in a miata would be plenty, especially with the lightness of a 7b engine! so now i want one... how hard would it be to build one from existing parts (and building a coustom e shaft)???? thanks, heath
