Speaking of under hood temps...

[MaddBaggins]

Has anybody seen these? http://www.raceace.com/products.html?x=32&y=5
Hood louvers. 4Wheel & Offroad put some on a Cherokee last year. 30* drop at the alternator, 15* drop on the air filter, 20* drop on the hood surface. I'd like to hear some opinions on why you would/wouldn't do this.

looks like it would work and it seems to make sense but they are pretty ugly. i could not butcher my hood for those.

Thanks for the link semlin, I missed that thread.
I like the way these race ace ones look and living in southern AZ its 100* plus from May thru August and 105* to 115* is the norm in June/July. Rain is scarce and deep water crossings...whatever. If the water is deep enough that the louvers would be a concern than I have bigger issues.

I have a friend with a Chevrolet 1 ton 4x4 tow truck who has had louvers like that in his hood for over 15 years now. Before he installed them, his truck would overheat a lot. It hasn't overheated since he put them in. He bought his from a marine (boat) store.

If you want to dump heat at the top, just remove the rear hood seal. The base of the windshield is a low pressure, relatively dead airflow area, so a good amount of air will come out there. But they didn't put that seal there because they had leftover rubber! Hot underhood air released on the top of the hood area will be sucked into the fresh air intake for the interior, located at the base windshield. The rest blows around the sides of the windshield to the next low pressure area, your open window!

Well, good point Kevin, but I don't recall ever seeing you wheel with your window down and I'm willing to bet your AC is on recirc, just like mine.

Here's the worlds fastest 80- it's got some nicely integrated hood vents.

On the trail I run recirculate, the A/C is the climate control type, so it does it's thing windows up or down, most of the time on the trail they are down. I am not saying don't do it, just that it's easy to try it by pulling the strip to see if you like it and it does any good before cutting holes in the hood? Wheeling on a day like today I don't need any extra heat!

That appears to be you spotting me down that bump and my window looks to be down?

Yeah, and that appears to be January, although here in AZ you still aren't looking for any extra heat on the trail.

LOL, ahh the proof is in the puddin. In my defense, I had my eyes on your tires, spotting you down. I'm gonna pull that strip and roll with it that way for a while and see what I think.

Oh and thanks for posting a pic so everyone can see that extra large belly I got there

Hey Alvin,

This sounds like a great idea, especially as the chicks dig louvers! I just don't want you talkin' smack at stop lights and getting into street races.

Thanks for the info Kevin, a dose of reality.

Mr Baggins, I am thinkin that a couple of these would improve the looks of your hood? They even come in brown!

I downloaded a short video of hood vents w/ a streamer and it is amazing the amount of air that moves out of them. (of course, now I lost the link addy)

My truck is black, so you can imagine how hot the hood can get. I have to say, I'm tempted to do this on the hood.

I would guess that removing the seal at the back of the hood would only cause suction at higher speed since the base of the windshield is a high pressure zone, and be noisy.

Only thing is water intrusion and more dirt/debris inside the engine bay...

maybe something like this- 3dcarbon.com

I was thinking just one over the passenger side (above the headers) would probably do alot.

Even if rain was to get down in there, there is not much to worry about.

Yup, one look at my engine bay is proof that plenty of water splashes UP into the bay.

Now you worry about dirt? C'mon cut those already, will ya...

P.S: Just becarefull when you cut the hood you dont want to cut the hood support underneath it

 

[FirstToy]

Oh no! I've entered Bling-dom and didn't realize it!

well, since you cut it, have you noticed any difference in heat? Can you feel alot of heat coming out of the vent at idle?

The vent is actually facing the wrong way for my purpose but... dang, now i'm going to be searching bling-tech

 

[LX_TREME]

well, since you cut it, have you noticed any difference in heat?

Yes, Of course

Can you feel alot of heat coming out of the vent at idle?

Certainly, I usually let it idle before i turn it off and walked to the passenger side and have my hands feel it and alot of heats came out of the scoop.I would say about 90F and above

LX,
in your bling-resource, is there a vent that is has hidden bolts like yours but w/ multi louvers like the carbon one that I linked?
