Golf R flutter or compressor surge (vids included)

[Tobes_WIR35]

The Carbonio isn't really an intake, the stock air box assembly has baffles etc in it to help reduce the noise coming back through the system from the BOV/diverter valve etc, wacking on a pretty carbon piece to the front of it really isn't doing much (compared to complete replacement of the system with VWR/etc). So it may have been there but hidden away a bit (as Candyman says, under the right conditions he can get his stocker to do it, I guess the sound is just a bit more subtle with the stock air-box/filter assembly vs the complete intake replacement).

I'm not quite sure what you mean? The carbonio is a complete replacement for the intake system. Stage 1 is a new airbox with a pod filters, stage 2 adds a carbon fibre pipe from said airbox to turbo outlet.

At least it is on a GTI anyway?

The R uses the engine cover as an airbox, so the Carbonio is just a fancy new snorkel piece to the existing airbox(stage 2 I think does rid the engine cover entirely and so is as you have described).

Ah right, my bad. I have the stage 2 intake system on my GTI which makes the turbo induction noise and blow-off/compressor flutter pretty loud compared to stock, which has made the apparent wastegate leak or whatever it is considerably louder
