On the other hand so far it does not look like anybody other than

Tom

is

interested in P-ports. Am I ten years ahead of my time again? :)

Paul,
I have no doubt you are Paul, it's my belief that most are on the
conservative side and are waiting to see results, before they make

the

plunge.

No matter what the initial results, I guess we will see Perry's

soon - I

feel that PP's are the only way to go, for the additional power and

simpler

inlet manifold.

For those not currently convinced, it won't take much time for them

to

recognize the benefits, especially if they need that extra power.

The big problem is the several  airplanes powered by Power Sport

P-port

engines

don't show up at the big air shows and they don't race. Is something

wrong?

In the good old days Everett Hatch and Allan Tolle would show up at

most

large

air shows. Allan would blow everybody away in the time to climb and go
238 MPH in the Sun 100. Everett untimely death set us back at least 10

years

and maybe 15 at the rate we are going.

Paul Lamar

Paul,
I would have to agree with you, were not were we should be by now.
However everyone's doing the best they can -I'm doing my best ( under
Butch's help and direction) and Jerry sure is as well,  as are some

others.

You are obviously doing the best you can, as a matter of fact one of the
newer members building a 4 place Vision with a Rotary ( Aussie) said

"How

does he find the time to do all this stuff !"

My response was ( using Aussie vernacular) " Buggered if I know !"

I'm sure things will take-off soon, I think our biggest draw-back has

been

the lack of testing facilities to test concepts, which takes the

guesswork

out of the equation.

For my own part I have to seriously concentrate on building a

demonstrator

and test rig - could you explain again how your  Dyno works. All I could

see

from the Photo's was that long shaft ( on the frame) held by two

bearings

(one each end) ?

George ( down under)

Well the entire firewall and everything forward of that is free to pivot
around that shaft. Newton's law: for every action there is an equal and

opposite

reaction. So when the engine puts torque into a prop the engine tries to
rotate in the opposite direct with an equal torque. Measure that torque

and multiply by

the prop RPM and you have all you need to calculate the HP.

HP = T x RPM / 5252

Paul,
Ah-ha, the penny drops!
Thanks again.
