Seems like the Long EZ has lots of room on top
so here is a variable length manifold that pops out of the
side of the cowl on take off and climb out. You need all
the power you can get to takeoff on short runways with canards.
At top speed where low drag is needed it close up flush with
the cowl surface and amx HP is generated.

This is two inch tube on a four inch center line radius.
Exact copy of the Lemans manifold. 240 HP at 7500 RPM.
You can tilt them back a few degrees to get a bit more
room for the alternator.

I further simplified the variable length feature when I realized the
plenum would hold the movably tubes in perfect alignment.
Now all you need is a push pull cable up to the cockpit.
A flexible control cable, a pulley and a large spring would also work.
A stuck manifold would be no more catastrophic than a stuck
constant speed propellor. Another advantage of this approach is
it allows a larger plenum. The injectors are installed in  pockets
in the side of the plenum. I am sure Ed Klepies can make one of
these for you.

I should get a patent on this thing :)

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,

Wouldn't you have to have a slot in the cowl where the snorkel could move from side to side?

Better than that Barry.
Here is what it looks like in the take off mode when the pipes are four inches longer.
I think I can get that number up to 5 with a bit more tweaking.
