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.

Paul Lamar ...No rotor no motor.

formula 1 is about to institute an engine development
freeze, but the past few years the f1 engine
manufactures have been spending a total of about 500
million per year in development. just imagine 500
million spent on rotary development. the renesis has a
9000 rpm redline, just imagine how fast the f1
engineers could spin an all ceramic rotor without the
rotating weight of oil cooling. i bet they could get
1000 hp out of a two rotor non-turbo

It always amazes me how they can spend that much money
and still stay in biz. The sponsors must be getting
their monies worth.
