Three concepts in intake design have come
together
give the over the
top, cool side  p port intake new life, at
least
to my mind.

   1) The snorkel ram intake that Paul has
featured in many of his
recent drawings.  Bringing air into the
plenum
previously required a
lot of ductwork and blocked access to  things
like
the dip stick.   The
snorkel is direct and efficient.  I have gone
from
not liking the
snorkel to loving it.

  2) The use of tight radius bends to really
get
the intake low over the
engine.  If these have to be custom castings,
so
be it. It is just a
180º.  If for some reason these  are  not
practical to cast, then they
can be made from carbon fiber.  Others  have
already made CF intakes.
It is time to free ourselves from off the
shelf
stuff that does not
fit.   The tight bends  combined with the
snorkel
give us the
opportunity to make a much shorter intake
that can
be easily be tuned
to the proper (18" to 22") length.

  3) Because of the snorkel and the tight
radius
runners, the plenum can
be placed over the center of the engine,
under
the  high center of the
cowl in the one place there is a little room
to
work with.

I've noted that you are looking for a way to
make
smooth tight radius runner shapes. Have you
heard of
Donuts? (Not the edible ones) Sometimes sold at
the
swapmeets,they're stamped in a half donut
shape, then
2 are welded to form a whole donut. You cut
them
across to get 2 tight radius 180's. Try 805 871
5494,
1331 Flower st, Bakersfield, Ca,93305.

Thanks Robert.  the two inch donut would save
considerable space as
it's o.d. is only 6 inches. Unfortunately, I think
they will be too
tight but I am going to check that today to make
sure.    Perhaps we
could cut the 180 in half and  drop in a little
piece of tubing to get
an exact fit.  This may be the simple answer to
this old  problem that
has given us fits for  years.    Jerry

The Donuts come in various sizes of course. I haven't
seen that same vendor at the swap for some time, but
last week's swap a different vendor had a stainless
sample.
