Hood vent ram air

Meatman8769 · Jun 17, 2022

Just a heads up. On the mopar parts website this hood vent ram air part number 82214741ab is 200$ off usual price. Which is like 700$cad

Yeah saw that today when looking at CAIs... Man it's expensive, still.

Oh ya. I ordered one from my local dealership. Was 780$. Returned it when I saw this deal. Have Cai already installed. Man altogether it's like 1500$ for both parts. Once my new mufflers in I'll install the hood vent

Just a heads up,it's not really a "Ram Air " per say,the hood vents are to close to the hoods surface to provide any Ram air effect. A scoop has to be a mininium of 2" above the hood to get past the dead air space.

That's awesome man, please post back some pics and your thoughts on the whole thing!

So what you're saying is it does nothing and it's a waste of money?
I think it's a cool feature.

Lets rain and snow in,lol. It is a cool feature,but functional not really,you're better off doing the eco-diesal airbox mod instead,or adding a duct to your factory box. Look past the oil filters,and you can see the duct i added to my box,it's the black duct in behind the filters.Do a search on here,and you'll find pic's of the duct mod.

Or buying a snorkel for forced induction based on mph. Lmao. I’m just partially kidding. .1 psi at 80mph. Or so the online calculator says.
Edit: ok found another website that states roughly 1psi per 100mph depending on scoop size and engine airflow cfm

Resale value for original “sport” style factory parts hold their value surprisingly well and are highly prized by collectors in later years when good original examples have cease production . Some factory options hold their value better than others but “factory options” hoods are for the most part a sure thing.

I’m surprised no ones mentioned real ram air mods.
For example some Hellcats remove a head lamp and replace it with duct work for ram air effect.

With some production vehicles manufacturers use a front fender panel assembly in line with the air intake and slightly widen it’s forward gap.

In this manner it’s purpose as assembled and engineered is to allow more air to pass through towards the intake filter and airbox.

Track style intakes. There’s a few guys running them. I would but being my truck is for off-road and not a dedicated race rig I don’t want to risk dust/water ingestion from the intake being low in the bumper or in the grill

Not to mention you have to be going like mach1 before you actually get a "ram effect."
But, fresh is always good too. lol

Or put a high rise 6 pack scoop on it to eat the air as it comes in?

Still wouldn't matter,there's a dead air space for roughly 2" above the hood at any speed. If you hunt up the wind tunnel tests on a 4th Gen it's very obvious,that's also why Ma Mopar used to reconmend a scoop that protudes at least 2" above the hood.

That's why I went through the grill with my snorkel.

You did a nice job on your scoop Tray,only downside to doing something similiar on a 4th Gen is the scoop would severely restrict airflow to the transmission cooler.The transmission cooler on the 4th Gens is the top part of the A/C condensor

Tray Burge · Jun 22, 2022

Still working on getting this completed and installed.
I have too many home projects and Jeep projects going on. lol

Yeah, the older ones are mounted in a different location as you can see here, but I did have to relocate my radiator overflow bottle to the left side.

let’s see what my truck reads for manifold pressure before and after my snorkel. Also hoping to see intake temps drop. I know highway driving my intake temps should be the same as ambient air. May have to get my snorkel wrapped or spray paint it silver. If I wrap it I’ll get it done in chrome to be reflective probably. Spray painting may be easier and cheaper up front since the black may absorb more heat. Thoughts on that?

It's tough to get your IAT's to ambient air temp Khris,the IAT sensor is past the air filter,and under the hood. If you get your IAT's to with-in 4 degrees of ambient,your doing very good. Are you installing a pressure sensor in the intake tube ,as i'm curious on whether you show a positive pressure at 60 mph or higher

If I ever get around to installing my plx wideband they have the option to add in an air pressure sensor to their kit that I may end up purchasing. I was planning on logging manifold pressure from the map before and after install to see if it changes. A higher vacuum would lead me to believe that the snorkel is more of a restriction to airflow. The same or lower would make me think positive pressure or no change.
