Just wondering if this is normal :-
sounds like I can really hear the turbo spinning/hissing
I was driving the car in 4th gear hard and at about 5500-6000 rpm with wot I can hear like a hissing sound so I let off the throttle then can hear the hissing/spinning sound which sounds like it slows down as the revs start to drop?
Tried it again and I noticed that on my liguid gauge that the bhp stopped gaining at 248bhp as the sound came back?
I really hope this isn't my turbo ****ed I can not hear the sound in any other gears even with wot.
Any help please?
