When I chose the type filter for the IV-P I built I
called K&N. I use a round filter as close as possible to the
filter shape/size the plenum will accept. A fellow at K&N did the
calculation and told me I had just barely enough excess flow for the turbo'ed
550. He wanted to know if it was in fact turbo'ed and the maximum RPM as
well as the displacement. I forget the
figures now but I seem to remember the filter had something like a seven percent
higher flow rating than the TSIO 550 requires. Everything is at the hangar
with the airplane but if anyone wants to know the filter number I'll find it and
pass it along. I need to adjust the bypass door micro switch anyway as it stays on now untill I reach up
thru the wheel well and open the door with my fingers. The door
opens at takeoff power as I see the light blink on (when the switch is set
properly) for a second or three.
