    The sound is more than likely the turbo spinning and when you change gear/let off the accel pedal a light woosh!!! from the DV.

    Sound is normal mate.

    the turbo is fitted right next to the bulkhead which in effect is just behind the dash.this could be normal turbo noise(do you know anyone with the same type of vehicle to compare?)or you may have a poor hose connection or split hose.i repaired an s3 last friday that had a cracked intercooler.this was quite noticable under boost.

    Yep sounds about right! The turbo aint quiet when its chipped, but it should be a constant squeel from 3000rpm up

    My money's on a split hose. If you took the hose off and revved up you'll discover it makes a big hissing noise. Nova - now that's plain ugly.

    Ha ha!

    There is one 2.0 Nova I know of and a couple of 2.0 Corsas kicking about Aberdeen. One Corsa I know of was rolling roaded at Star Performace at 164.5 bhp.

    A mates of mine up Grantown on Spey way has a 2.0 Corsa with throttle bodies and has been rolling roaded at 192 bhp. He keeps up pretty well with his dad in his new style M3! As you can imagine, his dad ain't too chuffed!

    i have been back to the dealer 9 times i've had the dv changed(now back to the forge one),both intercoolers and most of the pipes still the same [img]/ubbthreads/images/graemlins/frown.gif[/img] the brake's was a bit crap if you floored the loud pedal then tried the brake's the pedal was rock hard and not stoping the car if left for a bit then brake they worked a lot better so i checked the vacuum pipes for the servo guess what the pipe off the inlet manifold had split i put some tape over it and feck me it worked [img]/ubbthreads/images/graemlins/laugh.gif[/img] full power at last(well nearly still a small leak)just need audi to change the pipe it's booked in next week, so far it cost audi about 2k for a 10 bit of pipe!!! i bet they love me the tech's all run when they see me coming!! anyway thank for all your input [img]/ubbthreads/images/graemlins/beerchug.gif[/img] now i need to find that nova and show him what a real car can do now i have boost [img]/ubbthreads/images/graemlins/grin.gif[/img]
