Tony,

The sad part here is that is IS a good idea. A good idea by itself though isn't necessarily comercially viable.

I think you are right
unfortunately all of the intake manifolds I have seen are sand cast aluminum. Which can be very heavy. I just thought that
an extruted oval port tubing welded to a plate would be
impressively lite.  The problem here is not the money to make the tooling and get the extrusion, the problem is the minimum order. I can't have 300lbs of extruded aluminum tubing sitting in my garage my wife will hange me. Not to mention I have no room for that. What I may do is send the tubing to Wolf Aircraft they'll stock it there and then when someone needs it bent they can bend it however you want it. There I go again with my bright ideas.

Tony,
From my perspective you suffer from" excited about a bright idea syndrome" - I have suffered from this, as have many others have over time.We have spent a lot of money on things that didn't quite go the way we expected. Only to have someone with a slightly better/ different idea start the process over again.  This leaves one a little cynical, until such time things have been proven to work out- and generally they don't.
However we are conservatively interested in all endeavors and I have to admit to losing more money over a range of projects,  however I personally would be reluctant to invest so much money on this particular endeavor.
