Dunno. It's only been in my possession for about 90 minutes, and it's like 30F out today. Looks like it will work. *maybe* I'll get a chance to drive it on Sunday and find out..

Yeah it works. In particular, the vents on the sides move a ton of hot air out. If I were making a hood, I'd put a pair of extractors towards the sides and not worry about right behind the radiator.

I've had a pair of thin slits cut about 5" back from the back of your back side vent for about a year now. I did tuft testing and IR thermostat testing on the vent and it does move a bit of hot air out of the area, both at idle and at speed.
Have you gotten a chance to plug any of the holes and do some testing?

New to the site. An autoXer friend directed me to this post! Damn good info too!!! Well I need to vent the air from under my hood too. Heat isn't the problem. Its getting the air out of it at speeds of 170mph plus! I have a few good videos of the ca running and the hood lifting! Haven't played around at thoughs speed until the car gets a hood that well vent. Either one I mod. or buy! Here is my site www.ls1miata.net
