with 140km/h wind to cool it in addition to radiator fan

• yetihehe 3y ago
  I don't think fan was engaged anyway, never noticed it working when moving, only when stationary. I don't think it would help anyway. What I mean - cars can do fine for long periods under load as long as they are cooled appropriately, not only for 10s of full power.

    You look under the hood to see your fan moving while you're doing 140km/h? ;)
    • yetihehe 3y ago
      No, but I can hear it easily when car is idle, also see a change of power used by engine (fuel usage goes from 0.8L/h to 1.2L/h, not a small change). I purposefully wrote that I THINK that it doesn't work at speeds, because indeed it can be hard to notice it when going highway speeds. I would have to verify it probably with some CAN reader, but I think at speeds >40km/h it's not worth it to start the fan, air should be enough.

        It wouldn't on highway, only time where extra cooling would be needed if you were on actual track where you'd have far higher average power on top of slower average speed.
