OK, getting ready to be flamed.

I want to know if it is possible to produce a single rotor engine for installation in an MCC Smart Car. They currently take a 0.7 Litre engine, but can't produce more than 101BHP.

I reckon a single rotor could fit and hit somewhere around 125+ BHP.

Any comments?

Let the flaming begin!!!!!!

 

It probably can be done. Expect a lot of work and expenses. It might be much easier to source an existing single rotor rotary from one of the comanies owning a license and "automotive" it.
As always, anything can be done, provided your ready to $$$$$$.

 

how big is the engine in smart now? i bet the renesis isnt much bigger

 

For something the size of a Smart Car, you could probably just get one of those little rotary key chains and hook up some spark plugs and gas to it.

 

wont doing this basically defeat the whole fuel economy purpose of the smart car

 

Won't a single rotor rotary design off-set the counterbalancing inherent in the current design?

 

I get the feeling that mpg is not an issue here, correct? (otherwise, why ask the question.) With the little info that I got from last years DAS the smart engine is not much smaller than the Renesis minus stuff like the ac/alternator/intake... Maybe 25% bigger volumewise, but the dimensions are not the same. I suspect, like a '66 cooper with a v8, you could fit anything in anywhere. But why? I would like to buildout my minivan with a tube frame and drop in a crate hemi with a blower. Could be done.

 

Single rotor engines exist and are balanced with counterweights. This rotary engines list isn't entirely up-to-date, but it's worth looking at:

This 1.27 hp, 12 ounce, single rotor R/C engine is nifty:

This guy found a broken one cheap and fixed it. His write-up and photos are interesting:
