OK, I have a 90* elbow and large K&N filter from AFP. I will make a shroud to connect the SJ cowl snorkel to injector flange with cone filter inside. I have read the 2011 discussions by Bob J, Dan H and others on filters, inlets etc. This leaves three questions:
1-Does a bullet on the front of the cone filter make enough improvement to offset the potential failure of the bullet coming loose from the filter. The hazard is probably a fastener through the FI and I don't need the work if not worth it.
2-I theorized with Kyle at AFP, that the diameter of the housing did not need to clear the filter base much because you are not attempting to create a pressure recovery chamber. This could be erroneous if the velocity demand through the filter is much less than the snorkel intake velocity ?
3- I propose to build the filter housing out of Dan's glass/silicone composite. This would allow maximum flex for engine shake and only require one piece with two clamps instead of two pieces with three clamps. It is assumed that concern for Scat liner ingestion is a non-issue since the structure is pressurized in flight. However, ground run could be a different condition. Your thoughts/ experience ?
