I was going to fix the water ingestion problem by installing a pre-filter, A.E.M. bypass, and a splash shield. (I have mentioned this before in other threads, but did not want to go into detail on something to far off topic.)
When I was installing the water repellent pre-filter pictured in last post, the flange holding the filter on cracked. Not a good picture, but the crack is visable. The white material around the flange is foam, this also ripped around the edges when I was trying to get filter out of fender, clamps where rusted.
I am making a new bottom to the wave terminator box. This box is an expansion chamber after a calculated distance to Throttle body to attempt to tune intake. I don't know if it works like the math says it does, no way to test before and after. The white foam will be replaced with 1/4" polypropylene from that green cutting board.
(the parts where laid on plywood for future upper intake for photo.)
I still have to find a new flange to replace cracked one. I am not using same part as before to avoid future cracks. I'll have to walk around the farm store, Home Depot, and Menards till I spot something. I may make a flange from 4"od 3"id stacked plywood rings, if one of those stores has 3"&4" inch hole saws for low price. (intake is 3")
The A.E.M. bypass valve is actually designed to stop water ingestion. It bypass the FWI for an inline under hood filter when water starts climbing the tube. Modified Magazine test
I have the same part number they used in that test.
