When I got a rotor clock it just further impressed upon me how amazingly small our rotary is compared to a similar output piston engine. It's just over 12 inches tall!
The 'turbine' action of the rotary is more mechanically efficient than counteracting piston action. Also, the combustion volume is much larger in the rotary compared to a 1.3L piston engine. As we know, about its only drawback is relatively poor gas mileage, which the 16X is expected to address with its greater thermal efficiency.

You can think of each rotor as three pistons melted togrther into a triangle. The greater power per volume comes from there being one power pulse per eccentric shat rotation, comparable to the power per volume of a 2-cycle piston engine, which also has one spark per cylinder per crankshaft revolution--that's 2x that of a 4-stroke piston engine.

Huge hole is huge
Boosting a rotary is rather easy. Tuning it, though, is the hard part. The internals are all fine to be boosted, and if you tune it right, it will treat you right.

Whats the hard part about tuning? I know it isnt simple but its done so often nowadays I cant imagine it being that hard to find a safe tune.

I am getting really tired of people doing that **** to my threads. Of course if I was a girl in short shorts with an 8 you guys wouldnt be doing this.

check the threads Kane suggested...these things are stickies for a reason--so we don't get threads like this

From what I read it seems simpler to do it but there are finer lines you gotta follow. One mistake you could **** up a rotary but with a piston engine you need to sleeve and reinforce it. That costs a lot of money. And one more question. How much power can the rear end take in the RX8 before it gives? My camaros 10 bolt couldnt even handle the power it was given stock.

Why do you have to sleeve and build the motor? You trying to build an 8 sec car or something?
I think you may be missing some of the points. But your overall though is correct.... Rotary needs more airflow to make power than a piston motor; but it spools a turbo quicker, is smaller and more easily packaged....yada yada yada.
Also Rotary cannot take abuse (as a rule) like apiston motor... but has less working parts yada yada yada. There is no black and white.
