    In response to Bel Air kiwi

"The downside of that is that big fan out on the motorway at a couple of thousand revs is probably sucking 15Hp or more for nothing as the airflow makes it redundant."


Kiwi, this made me think. Is it really? If the forward motion air speed through the radiator and the air speed generated by the fan were the same (and a quick google of aircraft propeller design suggests that its not far off), then the losses would be quite small.
just thinking.
