Air drag at 140km/h doubles that at 90km/h. Air cooled motor temp at 110km/h remains around 100degC. I use fan at the end of motor shaft.MattsAwesomeStuff wrote: ↑Thu Sep 03, 2020 11:24 pmToo late to matter, but for conversation...
The thing about moving at 110km/h... is that you have air moving past at 110km/h. That's quite a bit of forced air cooling by definition.
What I want is to use other people's projects to fulfill my personal curiosity. I want to say "Try it and see what happens!" I want to know! :p
Mazda with its 28kw air cooled motor can sustain 160km/h for like 5min before motor temperature goes over 180degC.
Liquid cooling is way better and you can't force air at speed when you are in a roundabout crossing in the city. I found out motor generally overheats more in stop and go traffic than on highway... If you watch your speed of course.
