Back in the 1980's P-port rotaries were starting
to dominate car racing. The sanctioning bodies like IMSA
and SCCA panicked and started by outlawing P-ports. That did
not completely  work to their satisfaction  so they made
rotary engine powered race cars carry up to 650 pounds of ballast.

IMHO if there were no minimum car weight restrictions
and no intake air restrictions and no displacement limits (1960's Can Am
rules) P-port rotary engines up to four  rotors would dominate all
forms of motor racing with the possible exception of formula one
where tiny, cost no object, V8's and  V10's running up to 18,000 RPM
engines built with unobatainium metals.  (Basically Form One engines
are  a collection of model aircraft engine cylinders :)) In fact
with aluminum end housings and titanium rotors.... rotaries
might also dominate Formula One as well.

Turbo charged and non turbo charged.

That includes Indy and other forms of open wheel car racing.

The reason this is true is because of the extraordinary
power to weight ratio and superior durability of the rotary.
Lighter engine ....much lighter race car.

Mazda has yet to drop the other shoe. I.E. An all aluminum block
rotary engine for street cars.

-----------------------------------------------

You are staring at 120% volumetric efficiency right in
the face. The face of the rotor housings that is.
Fundamental to the high power the P-port generates.
No piston engine with intake valves can hope to achieve
this VE.

The nice new shiny stock Mazda apex seal is just starting
to close the P-intake port.

The wire is connected to a tiny high brightness LED
off to the left side of the P-port inside the engine.
