Boost whistle
« on: 16 April 2014, 14:46 »
My 150PD has a cool whistle when on boost. I love it. Reminds me of the 20vT I had in the mk2 back in the day.

You can't really heard it with the windows up, but drop them an inch and you can easily. I also seem to have a almost dump valve like noise when I let off between shifts.

Is this normal? obviously I don't have a DV on my TDI!

Steve's 150 used to that with a full turbo back system. You could hear it in the next county  :grin:

I told you they weren't in the other thread  :whistle:

My MK4 passed every MOT with the decat; one MOT tester even commented on the quality of the pipe

Guessing the cobra is normally the better option?
