Elaborate on why it won't work. The goal is to get the air to cool down from what it is at ambiant temps. The idea being that if we can more the air over a colder surface that the temps can be lowerd and made a little denser that we may see an improvement in quarter mile / 1/8th mile times. I don't think it'll cool all the air going in the tube, but it may bring it down significantly on a consistent basis. I've not had a chance to test this as most of the tracks in the area are hosting major events. So it may be another month before I can try this and start working up data.
