Classic cowling gills not closed, no cold box:
Separate air temp inside cowling in addition to GRT OAT. Measured with GRT
EIS/EFIS: under cowling at firewall close to battery: average 15C to
+20C above ambient temperature. Stickers on CDI never registered significan
t above temp.

The temperature label on my Softstart has not registered its lowest indicat
ion i.e. the temp has been <72C. This is with blocked side gills (the side
vents at the back of the top cowl). However, there is no lip seal around th
e airbox, so hot air can vent through the NACA duct in the top cowl, after
shut down. Typically in flight, the temperatures in the proximity of the mo
dules is about +20C on ambient (OAT), or up to +30C differential in climbou
t.
I don't see much point of a temperature limitation for the softstart; it's
not flight-critical, although the boxes under it are, and aren't helped by
intimately sticking the softstart on top!
