Need advice - Supercharger whine

[Audi Advocate]

I am getting maxed out on mods and need a reco on how best sound up the Supercharger.

Milltek non-resonated exhaust is excellent but I have not played with the intakes.

Looking for recommendations on how to hear the supercharger.

Thank you in advance.

A high pulley ratio and an open air intake with a metal tube. Doesn't really matter which one. All of them will sound like a pack of babies be fed slowly into a wood chipper.

[PopTart]

ECS Tuning makes a nice intake for our platform

[wilazn]

Been hearing good things about the IE intake.

I’m running an 034 Motorsport intake tube with K&N filter and I opened up the factory intake a bit. It looks fairly stock to the untrained eye but whines like a 10 year old.

I love my Roc Euro intake and awe touring catback. Just FYI may take awhile to get a roc euro. Not best customer service.

Metal tube and open element are the keys. I have the 034 tube and a factory airbox mod...it pales in comparison to CTS turbo and others. The silicone tube doesn't resonate like the metal tube and enclosure mutes the sound of air passing through the filter.

Having an exhaust (with stock downpipes) really turns up the whine. I had my roc euro on without my AWE touring and even my lady noticed the drop in whine.

Here's my USP intake:

Just had an upgraded supercharger pulley installed today and it's a little bit louder.

I have the CTS Turbo intake and the supercharger whine is pretty loud.

[BozMan-S4]

I thought I wanted the SC “Scream” and ordered a Roc intake. I have another car with metal tube Stage 1&2 spectre and you can hear it over a jet taking off lol. Well...Surprise surprise I never got my Roc and canceled my order. I went with the ECS carbon intake instead. I couldn’t be happier...it has a great “whirl” below 2500-3k and then gets pretty aggressive above there. It’s kinda best of both in my opinion and looks professional when installed...no “Zip-ties” anywhere lol. I guess it depends on what you want. IMG_0325.JPGIMG_0327.JPG

Injen SP-series intake owner here. It is not the loudest probably, but sounds great and if their numbers don't lie adds some good whp/wtq as well.

Here's the clip: https://www.instagram.com/p/BVlU-AHj...-by=alexb.here Good luck!

I would do something about that Fuel Line

[doady22]

I went with CTS, pretty similar to roc euro, I have CTS exhaust and dual pulley, the supercharger screams like the first person who dies in horror movies......it's fantastic

I bought the relocation kit...will be handled this weekend. I wasn’t sure if people move it for safety or cosmetic, maybe both.

Exactly the setup I have ! The whine is fantastic, to say the least.. also obnoxious, but fantastic.

[jcpowell]

Anyone got a link for just a metal inlet tube that will fit to the stock airbox?

I bought this about a month ago and the hose they sent was a 1/4" hose (6.35 mm) to replace the stock 7.5 mm hose. It didn't work, too small. I spent half an hour trying to get the new hose on just one of the stock fittings and gave up after I noticed the blister on my finger and I had only gotten the fitting about a quarter in. Double checked my order and it was the right part. ECS did a refund without issue, but I had to finish the job with parts from my local stores which left me without a car for a day. Did you have the same experience?

Hmm, I ended up using their relocation kit and did not have this issue. Also added flex fuel sensor.

Cts turbo intake made her whine like a bunch of babies tossed into a wood..... Oh... Did someone already use that line. Nvm. Lol

[catalyst686]

I went with CTS, it's loud, people stare.

[KRp220]

who makes the most quiet open element intake?

[MN Blue S4]

I've got the AWE S-Flow which uses the stock airbox. It's pretty subtle which is what I wanted. Quiet just tooling around town and a noticeable but not obnoxious whine when you get on it.

[AudiS4SD]

I know it's subjective, but what is everyone's opinion on the volume of whine? I'd like an intake to get some whine, but not to the point of being obnoxious for long-distance travel.

From what I've gathered -- in order of loudest to softest (correct me if I'm wrong): ECS -> Roc Euro -> CTS/USP -> IE

Shameless plug - I have one for sale for B8 (up to 2012) for $25 shipped. Brand new in the bag. Sorry for thread jacking OP.

thanks, but i still want an open element style

[bajan01]

Are you going for the look, the sound or the performance? My setup (page 6 of this post) gives a subtle yet noticeable whine but uses the factory airbox...which isn’t what you want. I only point out my setup as you were asking for the most quiet (but open element) setup. What you are asking for is somewhat of a paradox. Yes, you can have the “most quiet” open element setup but it’s still going to be loud. I guess that “least loud” is a better way to describe what you want.

i'm not trying to split hairs. of the open element intake options out there, understanding that all of them are louder than the airbox style intakes, which one is the least obnoxious in terms of volume?
there, is that better? lol

[bajan01]

Meh...

If CTS is loudest I’m a little disappointed lol

IE offers the perfect balance IMO. Not really into loud intakes

I have the Roc Euro (for sale, actually). It's not loud on long trips. You hear it under hard acceleration. It's most pronounced from 2000-3000 RPM if you get on it. It is silent when cruising at a constant speed. It makes the most noise immediately after you hit the gas, and mellows from there.

I’m running an 034 Motorsport intake tube with K&N filter and I opened up the factory intake a bit. It looks fairly stock to the untrained eye but whines like a 10 year old.

How did you open up the factory intake? What mods did you perform to fit the K&N filter in the factory intake box? I am looking for 50% or less whine that I hear in most of the videos and wonder whether simply moving to the 034 Motorsport intake tube would do the trick.

[MSq5]

It seems that OP posted and left. Never replied further or told us what he did. Hummm.

My two bits, and that is all it is - - - it is possible to do too much with the whine if one is not careful. I agree that open filter element and metal tube will produce the most audible whine. But, that may not be the best choice for maximizing power and it can wear thin over time.

The single most important factor in being able to hear the supercharger is replacing the stock throttle body to filter tube with anything else. The stock tube has a built in resonator chamber that cancels out all or most of the sound. Any replacement tube that does not have that chamber will let you hear the whine.

Reinforced silicone does have the advantage of being both stiff, resisting collapse under maximum boost draw, and having some insulation effect from heat transfer from the hot engine compartment. Metal tubes will get hot quickly and have an effect (perhaps subtle but still present) on the temperature of the air entering the throttle body.

That is also the case with true open element filters if they are not isolated from the engine and exhaust manifold on the passenger side. Hot air has fewer oxygen molecules which means less power at the same AFR. You want to keep the intake charge as cool as possible and that begins with ambient air. That's why our cars are much slower in the heat of the summer than in cooler air in winter, spring or fall.

The stock airbox can be opened on the side facing the passenger side headlight. That will also increase supercharger whine while drawing air from an area much cooler than on the exhaust manifold side or general engine compartment. That is what I did. There is a circular molded area on that side of the stock air box. It is easy to open using an appropriately sized hole saw attached to a cordless drill. Obviously, the larger the hole, the more airflow and the more supercharger while. I'm satisfied with matching the size of the circular molding.

Higher flow aftermarket filters will also increase air flow and intake noise, including whine, if that is what you are looking for. I began with the K&N 1987, but have recently changed to the aFe Pro 5R, which probably has the highest safe flow rate (adequate filtration). It is a dual cone design that also draws air from the end, directly in front of the hole cut with the hole saw.

The combo seems adequately loud to me and probably maximizes air flow without raising air temperature entering the throttle body.

[bajan01]

My argument with drilling out the airbox towards the fender is that the air there is still warmer than the air coming from the front. The debate then is if you are getting more/better flow into the air filter by doing this or not doing this and only pulling from the front. In the end I honestly don’t think that there is much to be gained/lost here either way (in terms of power).

The real question then is more airflow or cooler air more beneficial? If the airflow is restricted enough to starve the engine, then airflow easily outweighs temp. I am not sure that is ever the case with an otherwise stock setup, however.
