Bologna, remove the weather strip from the top edge of the fire wall. Viola!
Stock hood with a 1" vent at the back. Besides unless your tracking your car you will never rail on the engine enough to actually gain the full benifits of a vented hood. For a street driven car your really not gaining much because your not getting the car that hot to begin with. I had a mazdaspeed hood on my car for two years. I know.

And ANY vented hood is better than stock. You don't even have to move to get it's benefits as the heat now has several (depending on the design) big *** holes to escape through. I'm sure that when you start to move, different designs will yield differnt results, but the premise is the same. Untrap the heat.

You guys are assuming that your engine bay is dangerously hot with a stock hood. I think I already made my argument on that. Besides if your temps are getting hot enough to prevent the cooling system from operating properly you'd better get a little more pro-active than just buying a vented hood. No offence to Brian (Wargasm) because i know him personaly and I think he is a nice guy but he would test the ridgity of marshmellows if you told him he might be able to see some differences between brands. In his "test" he states that his intake temps dropped by four degrees and then later by one degree. However I am talking about engine bay temps which Brian did not take measurements on. If you want to lower your intake temps then get some cold air ducted towards the intake. Don't spend a ton of cash on a vented hood expecting to see large drops in your intake temps when $15 worth of duct tape and sheet metal would have yielded better results. Also you failed to provide me with any data showing the difference in temps for any particular vented hood. So with that being said how you can you say that a vented hood makes your car run any better than simply removing the weather stripping? I am not arguing that vented hood will let hot air escape. I am saying that so long as your cooling system is working properly it won't matter. If you want to lower your intake temps for performance purposes then you should be ducting fresh cold air in towards the intake.
