picture of this hood tilt please
So it seems like not to many people feel the hood prop is fuctional or looks good.
it cooled my engine bay down by 12-14 degrees. this is on a turbo'd car. it worked for me. dont knock it till you try it
How does it screw up your performance aspects and air flow?
so basically what you're saying is cars that have ram air hoods, cowl hoods etc..... are f**ked up performance wise
i agree.. people argue about it 24/7. it seems like the more stock parts u have the cooler u are these days...
a few local shops in my area actually recommend vented hoods or hood props for aftermarket turbo applications. you may lose that wonderful "low pressure zone" that kadafi had a heart attack over, but the added wind turbulance drives heat out of the engine bay
hey - Im not the one that did the test - Ill try to find the article - it was a shop that ran the car with the hood normal and then let it cool down and ran the car with the hood spaced ... they didnt show any improvement with temperatures at all ...How does it screw up your performance aspects and air flow?

My CF hood doesn't sit right on one side, so I may try it just to even it out.
When i changed my hood I had to remove the cowl to get to the four bolts did anyone else?

il answer ur wuestion better...if u think it looks cool then do it if u dont like it take it of
drives it into the engine bay. Spray your hood with water, and then drive. watch all the water droplets suck into the bay instead of going onto your windshield. 100+mph its like a vacuum, all that water will end up on your rear engine mount or worse, your battery.
That just proves that air is being sucked into the cowl.
And biznatch, arent the ones with the cowl induction going for the positive pressure in the bay? hondas are negative pressure.
don't fix wat is not broken!!!!The cowl induction is taking advantage of the high pressure area at the base of the windshield when the vehicle is moving. It's to let cool air into the carburetor. Not to let hot air out of the engine compartment.

see how the hood seals to the open area of the air cleaner?
The other intake for the air cleaner on the right is sealed off by a thermo-reactive spring when the engine reaches operating temperature.
It's not to let heat out.
On a Civic? Lifting the back of the hood is pointless. Almost every Honda I've ever seen has the air filter at the other end of the engine compartment. The best it can do is nothing. The worst is that it screws up your aerodynamics.
The area at the base of the windshield is under pressure. Roll up the windows in your Civic, switch the A/C fan completely off, switch from RECIRC to outside air, and drive 60 mph. You'll feel air coming through the dash vents. That air is hitting the windshield and being diverted back under the hood and into the cowl. That's why there is a rubber seal between the engine compartment and the cowl.
If you do this mod and you have any exhaust leaks under hood, you'll probably asphixiate in bumper to bumper traffic.

Besides, it makes your car look like a 2nd gen Prelude with a busted hood latch. (hood opens rear to front)
