I have a 1" hose that goes to what I think is the regulator/rectifier. It's been so long since I've done any engine work I don't even remember what the components are now!
Anyway, I wanted to route this to a NACA scoop on the side of the cowl, but I can not find where to buy a plastic or fiberglass NACA scoop for a one inch hose. All of them are for a 2" hose.
What did you all do? Where are you getting cooling air from? My cowl is ready to paint with the exception of maybe adding a nana scoop, so I'd like to figure this out ASAP.
You sure you need cooling air to the regulator?
The UL Power install kit comes with all the plumbing for it so I'm guessing that's a 'yes'!
Mark, most installs I've seen pics of (including mine) take air for that blast tube to the R/R from the rear of the left cylinder bank. Use a one inch flange for ducting https://www.aircraftspruce.com/pages/ha/flanged/ductflanges.php cut a hole, rivet flange, clamp hose, done.
David is right - it was the way UL instructions said to install the cooling hose. I did mine on
the right, but it doesn’t matter which side.
Dave does your side nacho scoop go to your cabin heat?
