Brian, thanks for the note...your inlet has a 3" radius, right?

Beyond the inlet, since I don't have room to accommodate a flat K&N filter behind the inlet, I need to have a filtered path and a ram path (self imposed limitation of not wanting to increase the girth of the lower cowl). Discussed this with Tom and Mark, and one option is a round ram air duct with a throttle body like in a Bower, then a side-mounted flange to take filtered air from a filter mounted under the left inlet (in the lower cowl). That filter could be fed directly by ambient air (like with some IO-550's) or via a sceet tube from the left inlet. Cheers,

Bob,
I am using the 3 inch inlet and also the filter box,Plenum,and cowl by
Sam James.
Straight RAM/Filtered air. Emergency side duct if nose is clogged.(Bird), directly to inside of cowl.

I do see +1 inch MP.
System works great.
Just some thoughts,

Boomer
 
Bob,
Some pix's for comparison.
I think if you extend the snorkel 3 inches and
use the 3 inch ring and straight filtered air.
5 Knots. Ask Rocket:D







I used the one on the left.



Not much room to play with. Put my emergency air valve 2 inches in front
of the opening and had to make blister in cowl.

Good luck and see ya in April ??
