hood scoops

what do you all think of hood scoops on a TJ? i saw one style that didnt look all that bad.. if i did do it tho, i'd cut the hood too and make them funcional because i think its stupid to have fake scoops nvm the waste of $$

also, how do these work? do they get in the way of the spray from the windshield washer sprayers?

At one point I was looking for one because I was considering a supercharger. I really didn't see one that appealed to me. It seems no one has really taken the time to develop one that looks good on a jeep. You can some on the Averger Supercharger website. I went with a turbo instead and will be installing hood vents as soon as I get them. I don't remenber the website right now, but I found the company's ad in the back of last months J/P magazine.

Look at Oman's website also. He has a nifty (but pricy) heat reduction hood.

that one is fully functional, but that not on hood it on the windshield cowl, covers the vent below window, but as for functional hood on a jeep i say no, to much mud and other crude gets in there now why add more?

fwiw, I put a vent scoop on mine, during the winter it doesn't seem to do much, but in the summer (I don't have A/C) it does get a little bit cooler/faster air thru the cab. Other than that I just take the top off.

I am not trying to offend you, but reading your posts is like translating a different language. You know some of the words and you have an inkling of what the idea is, but you can't quite figure it out.

Oops, never mind. You said 'hood scoops'; you mean 'air vent scoops'. I've read that these were used for increased airflow on older jeeps.

Aerodynamically the Wrangler is not really a good candidate for hood scoops. The air hits the grill and then there's a low pressure zone above the hood towards the front. Then the rear is a high pressure zone as it bounces off the window.

Personally I DON'T believe getting cold air into the engine bay through the hood is a great idea. If you increase the air flow into the engine bay, you increase the engine bay's air pressure. If you do that, you make the radiator less effective.

Remember your engine is designed to be water cooled, not air cooled

Ideally you want to get the hot air out of there and encourage more air to flow through the radiator. The hood vents when positioned properly achieve this.

If you want a SCOOP, then IMO it's not FUNCTIONAL unless it's sealed directly into your air intake. The cold air is really useless anywhere else.

The AEV hood in my opinion is the best approach to a functional replacement hood if you want additional cooling. I'll be adding an ARB Safari Snorkel to scoop in colder air from outside the engine bay and have the benefits of a less dusty intake and "cheap insurance" if I'm caught in a flood.




Click here for more info on the AEV Hood.


Plus it looks AWESOME. It's got the functional performance look along with a touch of elegance. The twin powerbulges give it a sort of Mercedes AMG feel. The HID's and high tech rear view mirror compliment that





Now I just want AMG-like engine performance


BTW... add the HoodLift kit from Quadratec while you're at it... no longer burn your fingers when you lift the hood up after the engine has been running.





More info on that here...

I think the AEV Hood is sharp looking. But if you sitting at a stoplight (or even driving around town ) in a thunderstorm isnt it going to let alot of water into the engine compartment from the top?

Just as much water probably comes through the radiator as you're moving, or splashes up from the wheels as you come through a puddle.

The engine is very hot while running and any water droplets contacting it will probably evaporate FAST. If they do get through the vent, they'll fall on the engine fan which will scatter them in a mist and they'll dry up PDQ.

Not something to be worried about IMO.

The only thing you might be concerned about is splashing the nose down into deep water, although remember the hood doesn't form a water tight seal with the grill anyway. If you think you might be faced with deep water, keep a roll of duct tape and some plastic sheet in the car and seal off the vent and the hood vs grill / fender area. Some trail guides also recomment taping a large plastic bag over the grill and letting it get hot for a minute until you're on the other side and you remove it. The idea is it will create more of a bow-wave and an air-trap that will keep an air pocket in the engine bay as you cross the water.
