Talking about cooling...
I have the intercooler for the Rotax 914, per factory setup.
My airbox temperature sensor shows no difference if I seal off the
intercooler!
While solving my cooling problems, I learned a few things:
1) Naca ducts provide no ram air, but merely "allow air to get in".
2) The cowling is somewhat "pressurised" by the openings in front.
How is the intercooler supposed to work, "connected" on the inlet to a
naca duct which provides no pressure, and the outlet venting into a high
pressure area?
I know quite some folks are flying around with an intercooler. Has
anyone indeed measured the drop in temperature? Has anyone ever found
bugs or other contaminations in the radiator? If so, were they on the
bottom or on the top of the radiator?
