It has been said that this is like the Ellison.

 What do you think Paul?


 Matt-

 I guess the patent expired on the Ellison.

 Just curious Paul, do you like the Ellison ( I own 5 ) One on
my Lycoming and several others on projects.

I don't have any first hand experience with it but my hangar
neighbor Klaus Savier flew one for years until he switched
to EFI. We were considering making a copy but the cost of
all those small holes made it prohibitively expensive.
For a p-port engine we would need two the same size.

We were looking for a low cost solution for carbs
and the Holley 500 cfm 2 barrel was much cheaper.

The TBI-48-4/5 is listed to support an O-540 which.  The equivalent
model on Ellison's site lists that for up to 225hp.
