Port Tuning Wankel Engines
In many ways, a wankel engine is like a two-stroke engine. You can open up the ports to change the timing regarding exhaust and intake.
I've ground many an intake, exhaust and transfer port. In some cases, high performance pistons would come with stencils to place on the cylinder wall to grind the ports the way the piston manufacturer recommended for peak power at higher RPM's.
It seems to me that wankel engines would have the same type of tunability.
Can you port tune a wankel engine?
