Topic: Want upward air flow through engine compartment
I need air to flow upward through my engine compartment and out the hood.
I'm currently thinking that a louvered vent grill from Lowes, mounted so the louvers stick out above the line of the hood, should create a low pressure area above the grill when I'm driving and move air upward out of the engine bay.
A few years ago when I cut a 6" hole in the roof of my Civic, at about 60 MPH I got to see the Bernoulli Principle in action and it seemed like it really moved a lot of air. I was thinking that some 4" rigid ducting sticking straight up out of the hood and cut parallel with the ground would be cool and effective, but a louvered grill over a hole in the hood seems like a more elegant solution.
How do you guys solve the problem of getting the hot air from your portable generator set out from under the hood of your car without having it flow down over the electric drive motor?
