Hood scoop?
 
I noticed a TJ when I was walking outside to grab my CP Writing book and it has a hood scoop in place of the stock vent that is on the hood. So my question is does it actually help? I know what hood scoops are ment to do but does it actually work on a Jeep?

AzTJ 04-20-2007 10:39 PM

not there is wont... where the vent is, close to the windshield, there is just a big useless space. A real scoop out over the front of the hood would be ideal.

I love to say this.

Snake oil.

Hm, I had a couple 16 year olds tell me it made a big difference in the heat and A/C on the highway.... Big again these were 16 year olds..the kind that keep the Tornado in business, so who knows.

Engine performance? Not a chance.. If anything its going to improve airflow in the heater and A/C

That big vent in front of the windshield is your fresh air intake for the heater a/c.
Amy has one, I don't know if it helps since her fan is always on but it does keep some of the crap out of the vent.

I had a scoop installed on my YJ's (no A/C) and it did help force more air into the cab. It was a noticable difference when it got torn off one day...

My fan doesn't run on "vent", so it helps move some air into the cab when going down the road. Of course with the top off it doesn't really matter. Looks good though, I think.

I honestly think it looks nice, guess that means time to go on JCwhitney ($30?), or look around for a better price.

Dare2BSquare 04-21-2007 10:43 AM

Look on ebay. they usually have some there.

binaryking 04-21-2007 06:49 PM

Yeah it doesn't help engine performance at all. BUT, it does keep the vents from filling with snow and blowing it through the interior when you first turn on the fan in the morning.

I had one too. It was the $20 plastic one. It lasted about 5 years. After about 2 years the little supports broke and made an anoying Buzz untill it cut them off. At 5 years it just started cracking all over. $20 for 5 years.....not bad.

I liked the way it looked. It did seem to force more air through the vent which helps on Hot Days (no a/c). Heat does not need help....at least in YJ's.......cooks my boots.

Remember......face the opening Towards the windshield.

only way it would help engine performance was if he did this mod.

I didn't know about that. Why? All the pics in the catalogs show it facing forward. :confused:

cause they like the pics that way ?

cowl induction....

remember those ?


I mounted mine towards the W/S...

bluvikng 04-22-2007 06:07 PM

Ditto, on what the others said. It is just to keep depris, from clogging up your fresh air intake. That is all. If you park under trees, or like to use your vent a lot, not a bad idea. But as already stated, it does not aid in engine performance.

Dare2BSquare 04-22-2007 06:12 PM

Learn something everyday on this forum.

Thanks.

I park it in the garage and haven't had a problem with it mounted facing forward, when I need to replace it I'll put the new one on facing the w/s. It's mounted on top of the grate over the vent.

rebelBullDawg325 04-22-2007 06:57 PM

how will it force more air through the vents if it facing the w/s? with it facing forward its getting a ram air effect

I'm with you. I think it would go out...

rebelBullDawg325 04-22-2007 07:22 PM

the air comming rolling up the windshield would creat a vaccuum drawing air out of the vents not forcing into them. thats seems feasable, i wasnt even thinkin that till u mentioned, i was just thinkin more airflow with ram air than without ram air, but facing the w/s probably would have that vaccuum effect. isnt that vaccuum actually the same way cowl induction works. pulls that hot air out of the engine compartment allowing for colder air to be sucked into the engine

AzTJ 04-22-2007 07:25 PM

only when you are moving

rebelBullDawg325 04-22-2007 07:27 PM

isnt that when you'd be worried about it working? you're in the jeep while moving alot more than in it while not moving

squarelightsahara 04-23-2007 11:48 AM

I have had one for about six years. I mounted mine facing out. I have never seen one facing the ws. It makes a big difference with the vent flow. Especially on those warmer rainy days where you can't drop the top. Before you stick it down, make sure the jet for the windshield cleaner isn't blocked. Mine is slightly deflected on the passenger side.
