Rotation, in and out of phase, allowed by a torque converter is a good point.

It would never keep it in it's sweet spot.

It would be best to choose a static alignment between the two banks of rotors.

and lock it in with a direct drive...

Hmm, might have to put a couple of my 12a's together on a bench and investigate.

Did I mention, that my wife and neighbors, love me to death...

 

That would be cool.

I have to start rebuilding engines. Then I too can be popular on my street!

 

These guys did it on a dirt-track car with 2 13b's.

BTW the Tiburo was not Methanol cooled, it used methanol as it's fuel. That's why it won the emission test also on that USCC. And it ran 10's in the 1/4 miles. Did any mention that it was an Auto?

 

For every revolution of the excentric shaft, there is one combustion cycle per rotor. A two rotor engine has two combustion cycles per revolution that are 180degrees apart. by having the second engine having it's top dead center on the #1 rotor 90degrees after the first engine's #1 rotor, there would be a combustion cycle every 90degrees, which would be smother and produice more power since the greatest leverage is at the 90degree point. use a bicycle as an example. If you want to start moving on a bicycle, the greatest force you can put to the rear wheel is when the peddles are horizontal.

I would also run them as sepperat systems; ie cooling, fuel, ignition. I like the idea of using a universal or constant velocity joint. This sounds like a project I might try next spring.

Actually, Granny's shop kept the two motors in-phase to reduce the amount of stress on the coupling. Keeping the motors in phase syncronizes the torque pulses on both sides of the coupling. But it probably doesn't sound as cool as phasing the motors.
