A turbo just isn't going to work the same on a side port exhaust in comparison to the old style wankels.

Near the bottom, I wonder how much is 'slight'

well, i've heard of perhipheral ported (inspiration side, i mean) 13B's making over 300 hp at around 9K rpm... a 45 hp difference?? yikes, but more than worth it for an engine so much more efficient and clean...

then again, do you have an idea of how much more inefficient the side expiration ports would get as the gas density increases (using more boost...)??

If you think about it, the side exhaust ports comprise an area of about 1.5 times larger area than the previous peripheral ports. That is hardly an indication of less efficiency.

peripheral port exhaust is very hot and it is still expanding when the engine is under load. This will spool up a large turbo rather quickly.


The side port exhaust from a Renesis is bound to be much cooler since it should convert that heat into more power to the eccentric shaft.

Since the energy went to the rear wheels, it would take more volume of exhaust gas to spool the same turbo charger.

Perhaps a smaller turbo or even twin turbos (not sequential) would work the best.

To me, it would depend on the application and the rpm range required. For example

Formula One; I would develop one using a large turbo.

Pickup Truck; two small turbos OR

GT road racer; One medium sized turbo.


Of course size is a relative thing here since it is only speculation
