Umm . . . those are on backwards. The point of putting vents on the back of the hood is to allow hot air to raise out of the vents. They way these are mounted is going to force air in and not allow it out.

Dunno who that is aimed at......

i think he means the last guy on the last page they are facing backwards like to the front of the heep like a ram instead of a cowl type of setup. not yours

haha yea thats letting air in ---not hot air out

im thinking of maby finding some vents from my bin of wonders, ill see what i can find. im also thinking of putting the spacers between the hood and the hinges. should i do both or either or?

I shimmed the back of my hood 1". I think it looks BA, like a shaker hood or something. You can feel the air pour out. Ya don't have to cut your hood this way....although I have no objections cutting hoods! I'm going to eventually make some 1" steel spacers.

I got some Z24 vents from the JY for 10 bucks been waiting to put them on.

A true cowl set up pulls air off the windshield to reduce under hood temps and allow cooler air to get to the induction point. Dose it really matter how the vents are mounted heat still rises and overheating generally occurs at low speeds. So forward or backward wouldnt seem to matter to me. If it corrects a problem the mod still works.

They melt the snow around them in the winter and radiate heat in the summer. Under hood temps have dropped, and trail temps are now manageable. Seem to work just fine, but maybe your right ,there is only one way to mount them. To me they would look retarted mounted the other way, and I had them. So I used them.

I was trying something else out this morning,already cut my hood and put in lebaron hood vents,I shimmed the hood up 1/2 inch at hinges to see what it would do,it did help drop temps a little more,idled it for 30 mins while I was wiring up the electric fan on a toggle switch and relay with a/c running,it's about 100 degrees here and temp stayed about 200 to 210

i dont think it matters much except at speed when it is fighting against the under hood air trying to rise up and out. but either way it will allow heat to escape so it will do its job

a1racer

i have been thinking about doing that as well cause you can feel the heat pour out of the vents so more opening would not hurt

I picked up a pair of them but don't have them attached yet. Here they are just set on the hood. I'm happy with them . They are slanted not square and match the contour of the hoods geometry well. I'm trying to decide the placement still and whether or not I'm going to paint them when I repaint the hood to match.

wait, You can shim the hood up in back? Anybody have any pictures of what that looks like? Before somebody does something like this, is there anything you need to do to prepare the motor to have water coming in on it? I am not water crossing prepped yet.

This is a cheap way to vent some air out the back. But I would like to raise a possible safety issue with this. I haven't test this, but I wouldn't want to find out. When you raise the back of the hood up, there is nothing behind it to stop it if you get in a wreck. It will probably get pushed right through the windshield. As a former firefighter, I have seen stuff like this. It is nothing to loose your head over.

Ouch, good point.
