I was tinkering with three possible sources of big whistle emanating from my new S&B intake, and I'm having great success with a very cheap modification:

There is a giant hole on the side of the filter housing, it faces the driver-side fender hole. I cut a hole in my old AIS housing in the same location, to improve air flow. There is a boot that is made (like a beverage cozy) to form a vent tube between the fender and the AIS housing, this prevents sucking in air from under the hood (allegedly). The hole on the side of the S&B intake is way too large to use the same boot for my old AIS, so I scanned the shop for something to suffice. I even looked in the rafters... which is where I found the answer.

3/4" plumbing pipe insulators... like a long, skinny micro-cozy. I cut a couple of lengths of this tube and wedged the short length at the bottom of the space between the filter housing and the fender. I took the longer tube and wedged it on the top three sides between the filter housing and the fender. It's cheesy, I'll grant you that... but it really muzzled the whistle under the hood. I now find the S&B almost as quiet as the AIS, with just a hint of whistle that's easily lost in the background - but it breathes better than the AIS.

I still need to solve the turbo bark and the black hole sound (all matter, light, and time being sucked into the spinning shredder), they are a different pitch and are more difficult to subdue.

I'll share a picture soon.

 

Rich, what about using some CLD tiles?...as used in sound deadening. Either on the outside, or inside, of the S&B box and lid?

 

What was your reason too switch from the ais too the s&b intake?

 

More air flow.

 

He has a thread a mile long on why he made the switch. It boils down to the ais not being able to flow enough air to clear up the smoke on this new injectors. Stick around a while you'll see how over **** Rich is about everything (in a good way).

 

We like to let Rich fire the large bore Buck$Zooka first, then we gather intel from his findings and SAVE, SAVE, SAVE!!!

 

Can you post a pic? I have an S&B intake as well and im curious how similar it is to the 7.3 version, because mine is a little loud as well.

 

S&B on left, AIS on right.




Yeah... I figured people would skateboard in my Buck$Zooka craters.

 

Is the S&B a paper filter?
Rob

 

There are two options. A gauze/fabric, washable version, and a paper disposable, as pictured above.

 

the s&b does have allot cleaner look without all those ribs in the hose, probably lets air flow through it better too i would guess

 

It's a breather for sure, they had to streamline the ducting, and expand the intake openings.

 

does the s&b not have a top cover or the gauge to let you know when the filter needs cleaned or replaced?

 

There is a clear cover on in that picture

 

So S & B don't sell a sleeve? I would think they do if the hole is there. I know mitt be pricey! It should come with it .
