On piston engines, there is a way to increase the stroke by offset grinding the rod bearing journal of the crankshaft; has anyone tried it with the rotary E-Shaft?

I believe it should work for a small increase in stroke, and also it would add compression as well. Yes, we are talking small amounts, but maybe we could get up to a 1.4 liter?

It would need some type of adapter bearings for the smaller E-Shaft diameter.

Any thoughts?
Anyone say "impossible"?

How would that work....it needs to stay in the correct position in relationship to the epichondroid shape of the rotor housing.......

So, it would not work without milling the rotor enclosure?

Hmm, something to do with scarred rotor housings besides melting for scrap?

won't work period........sorry

you really need to see the inside of one to understand how much it cant work..

go to how stuff works. and find the rotary section..

it might help..

It would take a whole new housing to be efficient. The idea is good, but wont work without building a whole engine around it basically.

What do you think the new 16X engine is.......

Yes, I had forgotten the seals still ride the housing on the intake stroke.
Longer seals to make up for the greater stroke would break easier.

I suppose you could increase the stroke , but only a tiny amount.
Anyone have a guess how many thousandths extra stroke you could get away with?

Anything more, and you need new rotors and the internal gear design too....

Hmm, change stroke and design a new planetary gear and rotor?

You really need to see a rotary apart...you basically have no room to do what you're thinking...it's not a piston engine ....I'm afraid you have to look in other areas like porting to change the way the engine behaves.....

Or get an Ls7 lol

Yes, the seals on the intake side cannot leak any more than one of the other sides of the rotor during compression or exhaust.

Let's just hope the 1.6 is a bolt-in upgrade.....
And the boost toys we have fit.....

wouldnt that be a wet dream.....

never happen though...

It'll fit with a big enough hammer.
