Holes in the hood club

OK so I did mine along time ago

I think that guy in the green Cherokee has holes somewhere, err I mean in his hood :wink:

Then Chris did his last week

who else has holes ( in their hood!)

tonight the newest member LARRY

Looks great Larry, some day I'll find me a set of those and will have more than a hole in my wallet!

OOOOOOOOOOOOOO Digger you have nice holes :shock:

why thank you

would it help to face those the opposite direction so it forces air in.

it has been my understanding that an engine will only suck as much air as it can, "forcing" air onto the filter does not help. All you are really doing is forcing dirt and debris onto the filter with them turned the opposite way, not to mention rain.

I recall the drunken debate I had with my friend over his "ram air" pontiac.

every time i see this thread title I think it should be "Hoes in Da Hood"

In my app, I'm using it to force hot air out instead of forcing cold air in from the hood. Having it this way, air will escape from the hood instead of being forced to go underneath and past the trans and t case

Yeah thats what I thought they were for, cooling. I would be concerned about rain too. I know the engine can have water on it, but all the time? Anyone ever have a problem due to this?

Forced air into the intake is supposed to boost performance though I thought...

I like Rivets....

Except all the holes I had to drill...

Too funny , thats the first question you generally get.
have you ever popped the hood after driving 50 miles in a rain storm, water splashes up all of the time somewhat, Won't hurt a thing, I have had several with "hoes in da hood" over the years and not one quit running due to a little dampness that makes it way in through the vents :lol:

Some over think a very insignificant thing

Boiler · **Posted:** Fri Sep 25, 2009 11:43 pm

Actually I was more thinking about corrosion due to constant dampness than I was about not running properly. But no, I don't think I've checked, or noticed it wet after driving in the rain. Didn't think about that.

Not so much overthinking....just trying to gain all the facts. :roll:

Doesn't hurt to ask does it? I've built lots of things in my life and feel confident arguing the fine points of fabrication, but when it comes to wrenching and engines I'm learning as I go with this Liberty. I want to learn all I can from you old guys. :lol:

Hey guys, really dumb question, what tool are you using to cut the holes into the hood for the louvers?

I would use a dremel with a kevlar metal cut off disc. Might go through a disc per side but the cuts would be spot on. the sheet metal on the hood is paper thin, just make sure you plan your placement around the under hood bracing.

I am thinking about doing this with mine, probably around the same time I paint the hood and roof.

Jig saw works the best with a metal cutting blade of course, dremels and others cutting wheels like that throw way too many sparks etc. for me

Chris went through two dremels cutting his holes

Don't worry about the bracing , I cut mine and the hood does not flex any more than before, been what two years or so and no problems

Forced air... yes. But for you to actually force air into an engine though those vents and though your air filter you would probably need to break 100mph before you see any type of hp gain, at that point, the drag produced by the vents would more then likely cancel it out. Air is not blown into an engine, it is sucked.

Now cooler air is a performance gain for sure, and that is what these vents are for. Supplying colder, more dense air to the air filter, as well as reducing under hood temps is a plus any way you look at it.

As for the rain, I am never to worried too much about that, dirt and debris would be my only concern (if the vents were turned around) Even still, you would need to clean your air filter more often- big woop. The rain thing comes from dealing with hondas for a long time, people putting these "cold air intakes" on them that relocate the filter very low to the ground... driving in heavy rain that pools on the roadways could cause I major problem. Of course, not an issue with the location of the KJ's intake.

Two dremels?? :shock:
