new project < 6 rotor
I woke up one morning and thought... 4 rotor 13b engines have been done.. why not 6?..
30,000$ later it might happen.. but that i think i can get (owning ones own buisness and living off rice and beans for a few months.. who knows?.
I know this is going to be huge, and while i have done work on my 1989 rx7 n/a (rebuild intake manifold, belts, plugs, wires) I have not gotten into the details of rotary engines. Most of my work has been on v8's and such so this will be new for me. This is not necessarily intended to go into my 89 rx. So dont think about space. this is more a project to waste all my money on so i can prove to myself that its possible.... and also to waste all my money for the next 5 months so that I dont have any to spend on my girlfriend .. heh..
I got this idea from another post and a TV show i saw a few days ago.If you are familiar with tractor pulling you will possibly know what i think im talking about. In tractor pulling there are large trucks/tractors usually with multiple v8's chained together to pull a large sled with a ton of weight on it over a distance. Same goes for this project. 3 13b's chained together in a triangle shape.
13b
==== < chain
13b 13b
. Now i dont have any specifics for this project but I do have an extra 13b laying around and can get more. Im thinking there might be some potential. I know that there would have to be a buge amount of custom fabrication on may levels. But i just wanted to throw the idea of this being a possibility out there. since the engines would remain relatively intact.. . relatively.. Im guessing that this wont be as expensive as i think. But it still would be . 20,000$ mabey. with the size of the 13b in small block form with some modifications to the rx7 itself this might fit in there..yes i know that is taking into consideration that the body would undergo extensive modifications. to allow for a new cooling system, new intake system, new exhaust system.. engine bay looks like it could be big enough but dont quote me on that one. Really this is an idea i had off the top of my head as my lazy *** got out of bed so feel free to shoot this down. I at least want to build a 4 rotor 13b type because its theoretically possible. Oh yea. and the other thing i forgot to mention. 6 rotor ecu. heh.. but in any case let me know what you think. Just a random idea.

hahaha nice one..
good point.. time to convert disk breaks to.. umm. . the flinstone mobile breaks.. ? an ship anchor?

You'd probably have an easier time linking two 20B's, though it'd probably be more expensive, but the e-shaft required for an inline 6 would be pretty crazy, unless you built a joint that goes on the front of the eccentric shaft (ie where the stock pulley is), and then to the rear of the eshaft (such as an adapter bolted to the rear counterweight)

money.. well i fix computers and do websites and crap for a living.. mosty web application development.. so i up my hourly rate. im not concerned about the $.. just doing it. and the 2 20b's is a good point.. the only reason i said 13 is because i have one sitting here.. although the 2 20b's would make things less complicated.
mab ill go buy this off whoever built it.

no im saying i have limited experience on rotary. ive worked for awhile on engines but my rx7 has been my first rotary. I like the idea of the rotary and now that i have an rx7 + a spare that i want to tear down it seems like an interesting project.

yea a single shaft 6 rotor would make for a real nice show car. true. but thats not the idea. now that I think about it it is a stupid idea.. but i do alot of stupid things.. hell mab ill put some 42 inch big tread tires on it and rock crawl..

um, just for the hell of it,
Do you think there would ba a way to attach two with a flex-point as SonicRaT mentioned above? sounds crazy to me, any chance this could happen in the real world ?.. I know that if you can dream it, and can machine it, it can happen(look at billy lane's hubless bikes....

why jump to a 6 rotor? Its a custom e shaft anyway. 5 rotor not enuff... like ya tested that and gave it the thumbs down.
120* 3 rotor
90* for 4 rotor or 180*... matching two 13b's or 12a's
72* 5 rotors....easy math
btw... easy NO answer..... no room, need a longer front. tube frame the car/chassie
If you can make your' own engines/ e-shafts then you can do it. Get a job w/ kiwi-re or someone w/ the tools to make dreams happen.
my vote-
do it w/ 10a's or OZ rotary airplane engines.

inline 6 rotor has already been done - it's old news!
but for a cheap way to link 6 rotors together on the cheap - arrange them in a triangle shape, and have another flywheel type arrangement in the middle of them, joining them all together, with a transmission on one of the engines to transmit the power
Wont exactly rev very quickly - but you never said that was a requirement
