bit of an odd one this.....when acceerating hard the other day i heard the usual whooshing noise (sorry for the terrible description) but when the revs got around 6000rpm the pitch of the noise changed into a kind of hissing noise which i can only describe as a very similar sound that an airline with an airgun makes......when the auto box changed gear the noise whent away.....
thing is the car drives exactly the same and doesnt feel any slower whilst this is happening. Ive only got the standard boost guage but that doesnt alter whilst i hear the noise......in fact the only thing bad about it is the noise for now but would really like to now what it could be and how it isnt affecting performace.
ive had a quick check over hoses and all seems well but im not exactly sure what to look for so i could have missed something.
also the car is standard with original turbo. And when idling with the bonnet up it sounds perfectly smooth with no noticable faults ?
help is appreciated as i have purchased another gts-t and want to find whats up with this one so that i can fix and sell it.
