Hi, recently i modified my air box.
I drilled some 19mm holes on the cold side of the turbo, i drilled about 18 i think.
Has anyone done roughly the same and if so have you encountered any abnormalities ?
I get a strange gurgle sound when the revs drop off from idle, i only notice this when staitionary and reving the throttle from under the bonnet.
Air box sounds great when in motion, i suppose taping the holes up would solve my query.
Any info would help thanx.
