It could help but for reasons contrary to what people believe. most people think it vents heat out, which it will do when the car is stationary. Under speed that angle is a high pressure zone and will for air INTO the engine bay, not let hot air out.
Then there's the cosmetics of it, not to mention the hood is designed to stay where it is if you rear end someone, I don't know how it will react lifted like that, it might stab you in the eye.

I was just asking lol, its back to normal right now. Just wondering if anyone had done it before with a second gen, ive never seen it done to one. Didnt know if there was enough of a benefit at idle to do this, i go to the mall a lot and theres always a good amount of stop and go traffic.

Yes, it helps with cooling.
At low speeds or sitting in traffic, the air is blown over the engine then UNDER it. With the back end of the hood propped up like that, the air has a little better time exiting out the top. At speed, like TTT said, you get a positive pressure area built up at the bottom of the windshield. Contrary to what others have said, there is no danger of getting decapitated. If anyone has seen FC's in a bad front end collision, the hood is designed to fold. The rear hinges are designed to keep the hood (rear) corners down and not shear. There are no hooks that keep the rear of the hood down - some other cars have this hook assist. The hinges have the sole responsibility to keep the hood from taking your head off. I do NOT recommend replacing the stock hood hinges - now THAT'S a BAD idea. Now the bad part... Thieves can hook your hood release cable and pop your hood open without getting inside the car. The stock route of the hood release cable is right on top of the driver's side fender. It's very easy to grab the hood release cable and pull real hard - viola, hood opens. Honda thieves do this all the time down here. -Ted |
