I found this thread extremely interesting and have been thinking about giving it a try my next annual when I pull everything apart. The posted results were pretty impressive.
Im running an O-360 and have found I can run LOP at some low power settings but never any higher. Right now for putting around depending on the day I'll run 2000 to 2150 rpm and can run LOP down to 4.5gph to maybe 5gph and still do 120kts to 135kts. Great for just boring holes. It would be nice to expand that LOP window some.
I ordered some honeycomb to try from
www.saxonpc.com
I saved my old airbox plate that was cracking so I have a perfect template to try and make a couple different versions. The one round piece with the small honeycombs is just how I received it. FIts perfectly. Its the default one on their site for MAF. It was $12.48.
The second, larger one I ordered at 120mm and 1/2in thick. It was $9.85. Just to try a larger honeycomb and maybe compare results down the road.
With shipping it was 26.52 total! for two different pieces to try. Ive got some left over plate from the replacement airbox plate I made and I've got some proseal that should still be good from resealing the fuel sending units last year.
I wont be installing one for months but just thought I'd share a good source in case anyone else was thinking of making one.
