Have you been talking to Rolf or Jerry?

Why are you concerned with minimum area? The damned engine will run with a
half inch hole in the rotor housing. The intake velocity will approach
super sonic.

Is that minimum enough for you?

We have two examples of P-port engines generating close to 300 HP tested
on dyno's with two inch runners. One of which with fixed length runners
dominated road racing road racing in the US for a decade where low speed
torque
and engine response was and still is absolutely essential. Then P-ports
were more or
less outlawed in US road racing as too powerful. Not fair to piston
engines.
Why don't you believe it?

Shessdsssssssssssssssssssssssssssssss!

Did I say anything about conspiracies? Rolf and Jerry are not the only people
advocating small runners out there. Tracy much to my chagrin also choose the
low power, four port RX8 engine for his latest engine. Despite the stock 
six port high power RX8  engine having 240 HP. Probably at the urging of Bruce 
Turrentine. A major mistake IMHO and so far Tracy has not gone any faster than 
his old 3rd gen engine. 

Bruce's new manifold with the tiny runners is indicative of his thinking on this 
matter. These activities set us back years IMHO. Everett Hatch was going 20 MPH 
faster ten years ago. The rotary clearly has a much better power to weight
ratio than any piston engine despite Mazda's excessive use of cast iron
for the end housings  but that will NEVER be demonstrated until people start
tuning it right so it can produce the power it is capable of. Unless we start
wearing these engines out we will never know what they are capable of.
What is inexplicable about this is Tracy has everything to gain and nothing
to lose. Unless of course he really does not want to sell ten times
as many PSRU's and fuel injection computers. By comparison my next door
hangar neighbor Klause goes out and blows everybody away racing his Varieze
and doing extremely well at Reno beating airplanes with twice the power.
He is selling electronic ignition systems like hot cakes. He is also
buying $200,000 hangars and one of the largest houses on one of the
highest hills around Santa Paula.

Pilots are stubborn like mules. Reminds me of an old joke. One farmer sells a mule
to another farmer telling him it is the greatest mule in the world.
The second farmer brings the mule back in a few days and says; "I thought 
you said this mule was the greatest mule in the world? I can't get him to pull 
anything let alone a plow." The first farmer picks up a 2 by 4 and smacks the mule 
on the butt and says "gitup". The mule takes off like a scalded cat. The first farmer 
says; "First you have to git his attention."
