[FlyRotary] Re: Non-EFI fuel
systems
Nice job on the intake
manifold, Rusty. Thanks for the info regarding the
Ellison throttlebody. Did it have a provision for
leaning? (similar to a standard aircraft carb)?
Thanks. Paul Conner
Thanks, and I'm sure you can imagine that you're
seeing the best side :-) I'll know if it actually fits in
about an hour.
As for
the Ellison, yes, it has a mixture control.
Sorry
Ken, but I don't agree with your view of airflow on these units.
I think they're more than suitable for the average NA
13B. To get a 180 HP, doesn't it take a
set amount of air, and fuel? If so, why would we need
so much more airflow than a Lycoming O-360?
Cheers,
Rusty

Sorry to say but I think you are dead wrong on the need
for high airflow on the rotary and there is no way 350 CFM will work
unless you want to fly a turd.
You did a fine job making that high flow manifold and I bet
you wont put a 350 CFM throttle body on it.
I had 1000 hrs flying time on my old coot with a 51 Weber
and when I rebuilt it I could not get another 51 as they are hard to
come by so I went to a 48mm instead and there was a noticeable drop in
power and I would switch back to a 51 if I weren't go to a
turbo.
For anyone thinking of a Weber I will say there are pros
and cons between a 48 and a 51, the 51 puts out more power but it is
temperamental on jetting and it runs rough on the bottom end compared
to the 48, there is also a 55mm Weber but I have had no experience
with it but would consider it.
