My Turbos sound like superchargers

[Quattrocket]

Guessing their cooked. where can I find the best deal on a pair of k04s? I was hoping this could wait until next year but I guess not.

[lil' is 300]

fwiw, I had the police siren/superchager sound for 10,000+ hard chipped miles and they never blew (eventually just replaced them under warranty cause it was annoying).

They could last till tomorrow or a year. Either way, there is some damage - but not blown just yet.

[AMC]

mine too! =) lol got the k04s in hand for backup lol

[Vuel Egham]

Just today the sound started... did a little pull on the onramp next to a tricked out Cummings Diesel, and sure enough—dentist's drill...

Might want to jump on getting K04's soon before they go up in price.. :(

Damn the dollar

[S4 in_lowplaces]

^^ agreed

[supasuprase]

I don't exactly get what you guys refer to as a "supercharger" sound. You guys scare me sometimes. I just bought my 46k mile S4 6 spd and ive had a few issues here and there already. Pulls hard, no mechanical issues (issue wise), but whenever i boost it sounds supercharged too. Back when I had a mkiv supra (PT61 .69ar) it sounded like an airplane. With this car, just says "WEEEEEEEEEEEEEEE"

Mine just started doing it the other day. Only when I have the apr program on though....

Well, the turbos are under increased load with any chip, almost double. They are going to sound slightly more aggressive because they are working harder.

I don't think its bad that you hear the turbos, turbos do make some noise.... But I think there will be a notable difference if you hear that high pitched whinning or siren noise that people discuss....then worry

[NOVAS4]

yeah you will definetly notice the difference between normal turbo noise and the dentist drill noise

[Quikslvr]

Mine have sounded like that for 10k.

[LUKAS(awd4eva)]

this is what i dont understand, when i had my old k03's at obo 90,000 they made no noise whatsoever. When i did the t/b etc changed they put in new k03's and from that day they wine like hell. Not that i dont like it. Is this good or bad?

If you want a set get at me on AIM: rippinralf

They already went up in price, too bad the dollar to euro exchange rate sucks, and to top it all off they are scarce right now, last year we sold 200 pairs of these to end users and loads of vendors on this exact forum

[fatezero]

Just picked up my set of K04's from Jeremy at Matrix and I got them in 2 days! Matrix had the best price and a great install kit.

Buy them now before they go up to $2500!

RS6 iz bettaahhhhH!!1

[silky]

mine give that siren sound too. mostly when the oil isnt warmed up. especially the 1st 8min of the journey im on. ive had passengers think there was a cop coming from a distance on a few occasions. my old ko3s did this... they blew at 65k. these new turbos have done this pretty much the same pitch .... maybe a little lower. .. wierd.

[my01s4]

my friend was stoned before and everytime i would lightly accerlarate he would look around for the police. it was funny. sounded like the old police cars

Thanks much AB!

We still have some K04 sets in stock. Yum!

[Videlov]

Hmmm, I think I've had the dentist drill ever since I bought the car, but I'm not sure. I got from the dealer with warranty, but they didn't say anything about it. Either way perhaps I should go check it out, just in case.

[JDM EJ1 95]

my brand new k04s make a slight whining noise in vacuum when the oil is cold.. very slight.. like you have to turn down the radio and shut all the windows to hear it.. almost sounds liek the DV's tho

[AB18]

Mine have doing that for 50k. After i did straight downpipes they really screamed.

[xx_s4quattro_xx]

Mines whine too when the oil is cold. Is that normal?

[SoSlow]

yes

[Reich]

Mine did a very loud sound. Almost as loud as my exhaust one time. They were not so bad after all. Too late, i've replaced them

[Dimcorner]

Mine have been whining for about 10k miles. Granted I don't get on them that often, but when I do I don't see smoke or anything and the car pulls pretty good still.

My KO3s now with about 50k on them whine at cool oil temp as well just in vacuum not in boost. It's been like that since I bought the car. Still pulls hard though, spikes at 19lbs.

[nateS4]

And for anyone worrying about high millage....I'm @ 124K with all maintenance completed. The car doesn't burn or leak any oil. It shocks the hell out of people when I tell them its an 01 with 120k. Props for a well built car (not a money pit yet).

[xx_s4quattro_xx]

mines is a 2000 with 130k still runing strong.

[AudiHolicS4]

Is that with original turbos??^^^^

[xx_s4quattro_xx]

im thinkin they are? i bought the car with 118k from the dealer no smoke or anything. I just need my tie rod change thats it. When i got the car it was stock with just h&r coilovers.

[Allaidback]

so is this "dentist drill" sound in boost or vacuum? I have the "spool" sound in vacuum, but nothing noticable in boost.
