Can you make a 20b+20b?
 

So the idea came to me last night that I needed to build a car. Now I have seen people do FDs with 2 13b's put together... so I was thinking could I do that with a 20b?

Now before people start going on with how long it would be, how it will not fit in anything...ect ect this would be a new car! I want to make the frame/body all of that from scratch. Don't give me the BS of ''if you have to ask you cant afford it''. Now there is about a cap of $500,000.01 on the project (and yes k500 is doable)... so dose anyone think that this could be done for that?

No this is not a project that is going to start tomorrow haha as all of you could guess... I am just looking in to it to see if it can be done, it will take years to start any of it, but I feel we need a super car powered by rotary and I want to make it :001_005: I would like this thread to be fun and toss around ideas on what could happen. So don't put it down and just say this is stupid, I would just like to know what the rotary community would think and if they had any ideas on how to help get it made.


Thanks for you guys time, have fun.

I'll buy one.

There actually is some pics of a 6 rotor engine out there. Not sure if it ever worked or not.

you can couple anything together. just the effects of flexing acting across the coupler.

Pretty sure the E-Shaft would be an issue.

Ok so I guess the best thing to ask now is how have guys linked 2 13b together?

+1 but since money isn't an issue then start looking...I know the Australians produce 4-rotor e-shafts...unless you know people with the right machinery here.

If you do go through with it then it belongs in this:
Factory Five GTM kit car.

From what I understand, they taper the end of one shaft, and insert it into a matching hole bored into the end of the other shaft, and use a key to connect them (like the front hub to e-shaft, etc). I imagine you could also spline them, but that would be harder to machine.

I don't really know anything about the subject, but those seem to make sense to me.

Let me see if i can dig up an evil forum thread from a while ago that touched on this subject...
EDIT: Yeah, here it is http://www.rx7club.com/showthread.php?t=697696 some good insight in there.

Not what I had in mind but god damn! I have never seen one of them and they are only $20,000 its just awesome! Damn good looking car but a corvette motor seem to be fitting vary tight in there... I don't think a 6 rotors would fit in there :(... hell come to think of it how long would this thing be?

:suspect:

Thanks for the link some good stuff on there...

Now as for machining it don't matter how hard it would be. If it can be done and be done better then that's the way it will be done. With the power that this would be making (1000+ :) ) there is no need to make the E-shaft out of anything but the strongest mineral I can get my hands on even if it adds a bit of weight.

when you put it that way :o11:... ya it can be done haha

Stock RX8 eshafts have been known to take the abuse of 1000+ hp.

I'm just gonna say it.................................. why?

yes RX8 shafts can take that. but the length of the motor is what I am worried about, my guess is would not be able to take the stress and just twist its self in to pieces...

as for why? why not. yes there are better things in the world to spend it on... I could have a army of FD and FC in full race prep for the price but why would I do that? why not make something new and why not make it as fresh and crazy as possible.

Ive had the crazy thought of the 6 rotor go through my mind before.
But just now I had a great idea.
Ive heard somewhere a couple of times of making a car with two engines, like a front and rear configuration.
So the idea is get two 20b's, make a car with one 20b in the front an one in the back.
Then you can just call it a 6 rotor. :)
Or you can push the envelope with two 4 rotor engines, an call it an 8 rotor :D
How exactly you make a car with two engines, one powering the front an one powering the rear, is still a little bit of a mystery to me.
