6.8 V10 Breather "Moaning" Fix

This is probably the best mod Iíve made to our Georgetown. (if someone has done this, my apologies for not finding it) The air breather inlet for the 6.8 is located right in front of your wife's left knee.! Who remembers that Quadrajet carb on a big block Chevy "moaning" when stabbed wide open?! Got the 4Ē flexible downspout tube with 90 degree fitting from Home Depot. The flex 90 fits perfectly over the "bugle mouth" inlet of the breather box. Then cut a short piece from the 10ft hose to curve down towards roadway and zip tied in place. The black tube blends well with the chassis black. HUGE difference in noise when that ultra sensitive Ford cruise control downshifts on hills. ❤️

That's an interesting mod. We don't have any "moaning" but it sure is loud inside at WOT.

Do you know how many CFM's the V10 sucks at wide open throttle? That bend, the ribbing, and the additional length will add restriction and turbulence and I'm wondering if a fabricated pipe of smooth solid piping as is used on a car would help with the air flow.

I take it you have not seen any drop-off in MPG or power? About how many miles ago did you do this?

Where you have routed it to is where previous GT's had it routed. The issue was that driving through a rain storm water would be sucked up through the intake, soaking the filter and being ingested into the engine under high RPM's. My 2000 GT had this issue and Ford came out with a "jerry rigged" application that did not work. Might want to research and maybe rethink your install. Just a suggestion.

Nice mod but has the potential to suck up some water.

And don't even get me started on the poorly programmed Ford cruise control!

Moaning Fix

JD - Great idea ! I'll steal it but will most likely have a shorter "down tube" to prevent any water intake issue.

Thanks for sharing. Much appreciate the clever thoughts you gave to lessen the noise.

Take care.

Definitely noisy, I covered the inside of air box with Dynamat noise dampening material which cut the noise down considerably. Very thin mat and should not make a difference to air flow. Amazon has lots of different products. Definitely made a difference in noise.

I do like your idea and intend on using it. How about wrapping the tubing in some kind of noise dampening material?. I could see a definite advantage to shortening it and maybe facing toward the grill with some sort of bugle shape on the end. Think I may head over to junk yard and see if there is some kind of air inlet system I can adapt.

Thanks for the post, any way we can cut down the noise on these machines is helpful.

You might consider where animals like squirrels can come to roost. We had a squirrel storing seeds and food in my wifes car intake hose while it was not being used in the Winter. Didn't find it until I went to change air filter in the Spring. We also had a bird nest near my v-10 engine in the MH. Luckily I found it as well while servicing the battery. This kind of thing can happen if we are not aware! I covered the intake hose on my wife's car with a non-restrictive cloth and kept the squirrel out so far.
Good luck keeping the water out.
