Gentlemen:
Flew the reworked duct (Smooth inside and 3/8" Inlet radius nicely
RTV'ed to the radiator)and got the following results on this cool day
with the cowl flap still attached:
Ground Taxi:170 Deg. F
85 Mph Climb:195 Deg. F
110 Mph Level:185 Deg. F
120 Mph Descent:175 Deg. F @ 5,500 Rpm.
Should we fill in the space between the Duct & Cowl and try again?
Instrument back of Radiator?
Clueless in Santa Paula

We halved the intake area with no significant change in coolant
temp so the cooling drag will be lower when we get this pig snout
faired in. I am betting a couple of MPH increase in speed.
We will reinstall the water manometer instrumentation and take some
pressure or velocity data.
