Air box for Avcon conversions and split cowling
Posted: Wed Jul 04, 2018 4:57 pm
Ok I'm hoping this lets me post my photos. I guess I can only post 5 and I have nine so I will post 5 here and maybe 5 more on another post. When I put my Avcon conversion on in the early 1990's. I knew the orange scat hose for the air on would be an issue. I always see them in poor condition with holes which greatly reduces volumetric efficiency. Not wanting to have hose I made an airbox inlet that attaches to the airbox and it was an easy field approval.
In addition to not having to deal with the hose on cowling installation it also does not shake and crack the nose owl at the air filter. If left unclamped they don't shake it and crack it with the hose but to install the hose you have to remove the airbox and reinstall if you don't use the clamp at the forward end.
I also didn't want a nose bowl that you had to remove the propeller to get to the front of the engine. In the hoots you can see I split mine and have 3 machine screws per side with nutplates. I also got rid of all cowling screws and put in plus flush cam locs.
If the pictures down come through I will have Bruce post them.
Cheers, happy flying and happy 4th
