Tim is closer.
The pitot tube is NOT meant to increase performance, it is a gauge. The
probe has an axial hole on the end of the familiar tube, and a radial hole
near the back. These holes sense the static air pressure on the radial side
hole, and the dynamic velocity pressure in the forward pointing hole. Both
holes are actually closed from any flow. The difference between the sensed
pressure is a measure of air speed, which can be calibrated with air density
(altitude) and temperature to give a speed reading.

I still ascribe to the big surface area higher pressure per square inch at
the carb theory. The other limitation is the laminar flow right against the
hood working to diminish the actual working surface area of the opening. The
old Ram air under bumper kits the Detroit guys put on the 60-70 muscle cars
had 2-3 times the opening surface area of what was at the carburetor throat.
The pitot tube point is valid but I thought the pitot tube was used to
create a measured vacuum. I am certainly not a pilot nor an airplane expert.
Probably the most significant opportunity is to obtain cool air from outside
the engine bay.

Tim,
Not sure that a larger scoop would help you out. In many ways having a
smaller scoop with a long runner to the intake gives the best effect.
Much like a pitot tube on an airplane.

Well DrMayf,
The air box will probably not make a huge difference on the chassis dyno
as
that is a static test without the car speeding down the road. I still
will
try the stock base and filter and then the flat base and taller filter
to
see if there is a gain due to filter size. Larry P. and I shared some
discussion over this a few weeks ago. But I do plan on going to the Drag
strip and see if the same 2 tenths of a second ET drop occurs that I
have
experienced on other cars where I installed a fresh air system (20 HP at
speed due to a cooler denser charge of air). I suspect a 2 fold gain due
to
cooler air as well as a marginal 'Ram Air' effect although the scoop
opening
is not as large as I would like. Trying to keep it looking relatively
stock.

Tim, now that you have it finished, are you going to dyno check the
performance before and after? WOuld be interested in the numbers..

Listers,
I finally got the project done and had several requests for plans,
etc. I
have copied templates for the Fresh Air Box including measurements and
a
"how to" article. Because the templates were 'life sized' they needed
to
be
copied on an Oversized copier. Kinko's really sticks it to you when
you do
