I have recent 2009 engine data that has it at 200HP at 6000RPM with 175TQ.
I have a older engine data set that has 200HP at 6500RPM with 164TQ,
this is prior to '09

So you'll need 300CFM to supply 200Hp. Almost could use a single HSR48.
Now I said almost.

Skip,
No having the wealth of experience and knowledge of individuals such as
yourself, and not having the opportunity for in depth testing, I rely on
such things as research and a little maths. Quite obviously I have something
wrong with the maths, so if someone can see an error I would be happy to
hear about it.

For example I have taken 40 cu" (13B combustion chamber volume) multiplied
that by 3 ( 3 rotor faces) multiplied that by the RPM ( 6,500) and divided
it by 3 ( 3:1 gearing ratio), then divide all that by 1728 ( 12 x 12 x 12
=inches to cu inches) and the formula looks like this:-

40 x 3 x ( 6,500/3 = 2166 rpm)/ 1728 = 150 cu inches per rotor housing and
therefore 300 cu inches.

This is not considering density, and at 100% VEonly. Density can be affected
by atmospheric conditions, altitude and forced induction, including tuned
intake.

Other things which affect density are inlet velocity and the dreaded skin
friction - which is 2 to 3 % x  Velocity squared, in a laminar flow tube.

Inlet and tube diameter affect the inlet velocity.

So if your getting a whole heap of power from less than the max VE (what the
engine can breather without forced induction), I really want/ need to know
why?

Or my maths is wrong somewhere.

Your calculations are out to lunch. The real displacement
of the engine is 2600 cc or 2.6 L. We have have been over
this one thousand times in the past and you have received the
messages but I don't think you read them :) Perhaps you forgot.
I forget a lot of things as I am getting old.
