A six rotor would have SERIOUS issues with eccentric shaft rigidity. Like NA-only-drag-car-1-season-then-its-done issues. would still be freakin cool, though.

BTW, I'm gonna build a compound forced induction (SC + turbo) for my project car. Its still in the "restore donor" phase right now, though.


EDIT: WTF!?! I'm not ZoomBlack...... ???

I like the idea of lots of rotors - but with a much smaller capacity...

How smoothe would a six rotor be with 300~350cc per rotor??? It's not going to happen until the design can become more fuel efficient.

Funny when you think about it - there haven't really been that many true inventors over the years. There's a lot of innovation and refinement, integration and optimisation, but not much that's truly new.

i dont think they can use 3 rotors anymore because the overlap allows the unburned hydro carbons to escape

thats why they went to side porting

Why not a 22 rotor motor, it should make a whopping 2600 hp and would be lighter than a 16 cylinder engine. c'mon ya'll know ya want it and ya can shift it mad quick yo! I'll bet 0-60 would be sub 4 second, dallmmmmnnn dog!

Kev, back to a relatively serious note. The internal combustion engine has been around for 100+ years. Most of the performance upgrades (super and turbos, ICs, etc) have been out there for 70+ years. Even our beloved Wankel has been around for quite a while. Truly new technology is very hard to come by. It seems like we just keep getting improved versions of what we already have. Something truly new and innovative would be refreshing.

Theres plenty of improvements though, new stuff.

VTeck, variable capacity, electrostatic(camles)valves, common rail,multi valve ,new materials (alloys,ceramics) etc.

The piston engine has had an lot more man hours of development time than rotaries.

Absolutely the improvements are phenomenal. I am just saying the original technology is over 100 years old. Its lasted becuase it works and much of our economy is based on it.

It would be nice to have a 6 rotor in the back of a Lambo Replica. Would smoke all original Lambo's :D

...Just dreaming...

I'll settle for a 2 rotor with 1.6 displacement, and lower compression rotors for FI.

They tried to build an 8 rotor motor, but it kept twisting eccentric shafts. I think they even tried to build one out of titanium and it died too.

Let's just make the rotors stackable so we can add as many as we can fit

Not if they engineer the 6 lobe e-shaft to have support bearings in the side housings to cut down on flexing. It would be no different than any in-line 6 cylinder engine with 7 main bearings. I don't see the 2Jz Supra engine having crank shaft problems. It's all in how you engineer it.

Stacking a rotary isn't the hard part. Knowing how to properly engineer the e-shaft is something obviously out of Hurley Engineering's capability. That's why it failed.

Haha, I wish!

I'd settle with just being able to sit in a 3 rotor car. I've seen enough videos to know I want to own one some day...

No, it'll become a supercharger!

It's still a rotary except it's not a triangle type rotary!
