REFLECTOR: Engine failure causes

[Jim Agnew]

Brian, I have a large bore aluminum manifold mounted as high as I can get it on the inside of the engine bulkhead with 5 ports.  Two ports go to the tanks, one to the sump, and the remaining two go to two separate SS 3/8" pipes about 8" apart that go thru the bottom of the hull under the gear.  The pipes are cut at an angle with the angle forward to get a little ram air and have a 1/8" hole in the back just above the angle in case of freezing or plugging.  The reason for two was redundancy since each is more than adequate.

Brian,
 
I know when I was at the factory this Jan., and saw two high HP (turbo) setups they were working on in the builders center, I asked about the vent line... as they had them run up to the top of the fuselage, and then forward about a foot or so, and then loop back and then down.  I was told that the high angle of attack that the high power allows can overwhelm the factory vent system.  Both systems also had the check valve to vent from the cabin.
