Hood vents: Urban myth debunked, Highly scientific content ... Options

[SirAndy]

Every time i have a discussion with people about venting the hot air from the front oil cooler out the top through the hood there is at least one fellow who insists that that will turn the inside of the car into a sauna.

Well, today i decided to do a highly scientific experiment to see if there was any merit to that claim.

After a 20 minute spirited drive i verified that the thermostat had opened and the front oil cooler was getting hot oil.
The oil temp was up to around 200F (That is normal operating temp for my car) and the cooler was hot.

I then proceeded to drive with the top off at different speeds and used my well calibrated hands to look for any temperature difference of the air coming over the top of the windshield.

• At 80mph, there was absolutely no difference in temperature across the whole top of the windshield.

• At 50mph, there was absolutely no difference in temperature across the whole top of the windshield.

• At 35mph, there was a hint of a minute difference in temperature between the sides and the center.

• At 15mph, i got nothing.


And that was just the air going *over* the top of the windshield. Most of that never even makes it into the cabin.

Totally scientific result: Completely bogus, made up and not a problem at all!
