Turbo noise after acceleration

[TTA #373]

After I accelerate & let off the gas the Turbo makes a rubbing noise? Its not a whinding down noise.

If it sounds like a flutter..that is normal..

What is happening that makes that noise? Can I stop it?

It's normal, when the throttle blades close suddenly the pressurized air has to go somewhere so it reverts back to the compressor.

Only way to get rid of this and it's not 100% perfect is a blow off valve/bypass valve..................

I thought it was due to the puck cycling on and off the the hole in the exhaust housing. For the most part the system leading off the excess pressure on the hot side of the turbo. The flutter was the on/off rush of pressure through the gate.

When the blade closes I can see it slowing the turbo due to pressure but without a blow off valve there is no real place for it to go.

It vents to the atmosphere with a blow off valve. Some swear by them some say they're not needed on our cars.........
