Buyer beware!

[Strokerswild]

What we are calling "hood vents" are properly "heat extractors".

By design, at speed, the pressure behind the bulge (where the blinker is on '16s) lowers and higher pressure, hot air from inside the engine compartment is drawn out. There was a good wind-tunnel smoke test video made a few years back. Kind of a neat design.

And precisely why my open Roush airbox quickly returns to near ambient once moving as it's directly under the extractor. In addition, the OEM grille duct attached to the filter box feeds air in and allows the extractor to more easily perform its function.

the Mustang "extractor" is a complete joke. the ones on my CHallenger however I can feel the rising air column with my hand.

I disagree. The extractors on my '16 are perfectly useful blinkers.

Not a problem with the stock hood vents. Even what water does enter the vent just drains out the bottom of the air box.

It's actually not even a problem for the filter element to get wet. The engine will just pull humid air until it dries out. It's an old Dyno trick to inflate numbers. Humid air gives a slight compression boost since the water it contains is not compressible.

Water vapor is plenty compressible.

I will strongly disagree ... the extractors on my 21 GT work and work well ... IF you dump the stock hood vent covers an get a aftermarket one like my roush ones.

The heat extractors on the GT350 hood are absolutely functional and are not for looks. Otherwise it would have been blocked off. Every piece on the Shelby have a purpose. This isn’t your 70’s/80’s car with fake vents and cheap graphics. It worked so well they made a larger one for the GT500 due to creating more heat from the supercharger

hey, 3rd party can solve all sorts of warts. But changing covers does nothing to address the TINY slit that's in the hood. The opening in the Challenger is bigger than my fist.

The Mustang (not GT350/500) has a serious problem with venting and the only way to actually solve is is TrackVents or similar. Or an aftermarket hood that patterns after the aforementioned Shelby versions.

When my filter got soaked the car idled wildly. A/F swung back and forth 2.5 points. Surged at speed. Bucked at takeoff. Must have been really wet. Stock hood vents.

Looking forward to going back to the closed air box. Thinking about adding real hood vents.

On my Roush set up, the airbox is closed. But i also have roush hood vents that allow water in engine bay, but i added the black plastic part and problem solved,

If you use a GT350 airbox on a GT you also need to change the hood liner. It redirects the water so it doesn't drop onto the air filter. Go have a look at a Bullitt or a Mach1 that also have this airbox design. Check the hood liner and you will see what I mean.

1000% right!!!!

what issue??? I have NO issues with my 21 with venting....my engine temps and AIT's stay normal and in good working order. Only if those hood vents on the dodge made those boats faster though

Can't resist how fast do you run to feel that rising air column?

Who has their hand over the vent (oops pardon me the extractor) you or the wife....LMAO

Just don't drive in the rain. Problem solved. jk

 

[Grayghostcoyote]

bought a prefilter bag ...problem solved lol

I can feel it just sitting parked.

 

[Grayghostcoyote]

pretty much where a dodge should be ...just sayin
