I got the K & N installed. Im wondering if any of the other CAI owners can tell what what theres sounds like. My kinda sounds like someone blowing a whistle unde rhigh boost is that normal?

 

Yep. Under high boost or under moderate boost at high RPM's it will sound like a nice loud whistle. You will also notice that under light acceleration when you let off the gas, without triggering the BOV, you will here the flutter and it sounds kinda like a rattle snakes tail rattling. All of this is completely normal and cool as hell. At WOT the turbo will scream like a banshee and let everyone know it's turbocharged, others it may just scare the crap out of them. Glad to here you got it on, now kick back, relax and enjoy truely hearing your turbo for the first time.

 

that was my next question the flutter kinda worried me. Any idea why it makes that sound?

 

can you tell a difference?

 

"that was my next question the flutter kinda worried me. Any idea why it makes that sound? "

I think it has to do with the slowing down of the turbine impeller blades(or whatever it is called) causing turbulence with the incoming airflow - Someone on here can probably ennumerate it better than I but those are my thoughts.[8D]

It sounds AWESOME, though, whatever it is. It's even more noticeable with the short ram ( and now that it's cooling down outside, the benefits of the short ram I bought are finally coming into play)

 

yeah right now im running itas a shortram. Do to the rainiy weather where having my wife has no common sense so just to play on the
safe side I am running the short ram till the rain lets up.

Yes. Its not like OMG that was a big gain, but you can feel the car can breathe better. The sound is amazing also.

 

Told ya so. I believe that the flutter is from the turbulence of the impeller and incomming air since there isn't sufficient pressure to open the BOV.
