I seam to remember way back something being said about elect fans on exchangers in aircraft.

The reason for my question is if your prop doesn’t have very good blades for pushing air in tight to the spinner would an elec be helpful for sitting and taxiing?

My concern would be restriction of the incoming air once at speed and how it would go at high air speeds even with a good diffuser.

Has anyone ever used one?

I tried to emulate tracy’s 20b setup on the Renesis 4port 

I’ve got 540CI of Water cooler and 193CI of Oil cooler (out of RX7 turbo from memory)
