so i have a vrs se and on boost it makes a ...sound sort of howling wind.. the sound comes in as the turbo does and the car feels..i wouldnt say slugish but only a little down on power and then about 3-3500revs the sound stops and the car picks up

but dont kow whats causing it and not looked at it yet so just looking for a heads up of things to check

maybe cracked intercooler? its had new intercooler pipe seals

Check boost pipes first I'd say
