Re: Turbo whistle

Next week I'll have my Ecodiesel and I have an AFE cold air intake to put on. The Ram Ecodiesel guys say you can hear the turbo a lot more. I'll be able to post a YouTube video next week sometime.

Re: Turbo whistle

I installed the AFE intake on Ecodiesel and it was not what I was expecting, sound wise. I knew that there would be no power gain of any sort. I was expecting some more sound. You can definately hear the suction noise with the radio turned down and the window cracked open. Roll up the window and you can barely hear anything at all. Turn up the radio and the sound is gone.
I tried reving it at idle and it appears there is some sort of factory limiter so I could not take a clip of that. On a lonely quiet night, I recorded 3 video clips and the sound was not present in the video as it was drowned out by the diesel engines sound.
I am going to say that the GC has fantastic sound deteding thus not being able to hear much of the sound. Boo. It also soes not help that since we have a 8 speed transmission, as the turbo starts to build boost it will shift to the next gear. The AFE intake hooks up to a rubber hose coming off the turbo. It would have been better if the intake could have hooked up directly to the turbo as I believe the piece of rubber that is left intact might muffle some more of the sound out. I assume installation would then be more difficult

Would I have still bought the part for the sound it produces should I have know it was not as loud as I was expecting, yes.

Re: Turbo whistle

King Marty- are you saying you hear more of the turbo whoosh than whistle with a CAI? It's gotta be that damn silencer!

Re: Turbo whistle

Correct, but at times you can hear a little bit of whistle when letting off the throttle, it may be more the BPV but you can hear it a bit.

I would like to add the the install was very simple and a great fit. Rollin Smoke Diesel has the best price for it that will ship it to California. Other vendors would not.

One of these weekends, I am going to take out that other silencer and go to a muffler shop to have them cut me pipe in the equal length and diameter to see if it makes a difference in sound. I too want more whistle! lol

Unlike our DSMs (I have a 92 GSX) and other gasoline turbo engines, our Diesel engines do not have BPVs. FYI (had to get another TLA in there)

Yes sir! I've even been to a few of Buschur's shootouts! :-)

Anyway, yes. This diesel turbo thing is a different beast!

Re: Turbo whistle

Installed an AFE stage 2 pro guard 7 today and you can hear some whistle. You also hear some intake noise, kinda like air whooshing into the turbo. All depends on rpm and load.

Soooooo, has anyone given it a crack?? Go on, I'd love to know what it sounds like. I guess we would have to buy two, one for each pipe!
