Subject: [LML] K&N Air Filters
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.
