This is the next intake manifold casting project.
Low profile. Fits under a low cowl.
Will come in two sizes 1-1/2 inch pipe and
1-1/4 inch pipe. Sched 40. Incorporates the necessary bell mouths.
Will work with a fabricated sheet metal plenum.

Hi Paul, I like the look of these intake manifolds, I'd be interested in
a couple of 1 1/4"; are they designed with any particular throttle body
in mind? Also, has there been any response from SP about alum end
housings? I'd like a couple of those as well. Jerry mentioned that RB
have them already @ $1550 a copy; are RB housings PP only, or side port
as well? Dave McC

With Tracy's EFI throttle bodies are simple butter fly valves.
No angle sensor required.  The bigger the better.
Chuck Dunlap built and uses this really big one on his airplane.

Check out the throttle body from a large Mercedes engine. 3" dia. and very
simple and light. I paid $50 for one from a junk yard. Bill Hyde
