take that as a no then.... :headvswal

 

does anyone want to buy a supercharged zed... :shifty:...:whistling:

Sorry mate, I had a listen and don't really have a clue what the noise is...

thanks for listening anyway,

 

i've never heard a car make it, so im really confused...

Maybe one of the engine guru's can help out. Don't give up hope mate..

Sounds like either an airleak causing the whistle as the turbos spool, or an cambelt bearing but it not constant

Ive shown this to a couple of people now who have never heard anything quiet like that but both have said that sounds like an air leak somewhere? must admit i like the sound though lol

I still reckon its an air leak. but it also sounds like a dry bearing. :wack:

That sounds weird full stop

was stuck in stop-start traffic earlier and there seems to be a very slight rattle just before and after the noise, might be unrelated.

 

think im going to have to gully gut the air system and start over.

 

 

TBH an air leak i can live with, as i have to agree its a kinda cool noise, but until i can rule something more major out i cant leave it.

Sounds like a bearing noise to me, mind you I'm a bit deaf - so you may not want to pay attention to anything I say about noises heard or not heard :rolleyes:

Sounds like the turbo's spooling up. Do you have a decent boost gauge? see if the noise comes and goes with the boost? Have you got upgraded turbo's?

yeah they are turbo Technics stage 2's, and the noise is only on boost, ( noise is loud even at 0-1psi, which is why i don't think its an air leak nor did our technicians)

 

too loud for normal spool IMO, particularly as they didn't do it on the previous vehicle.

Sounds like it carries on after dropping the revs? or is it me.............

no your right it does carry on for a very tiny bit, after the boost drops, and like i said earlier does appear to rattle very slightly before and after the noise. although it could be unrelated.

Im thinking along the lines of a weak actuator maybe? You can here it dumping pressure when you let off and im wondering if one of the actuators is weak or set wrong and is staying open when its meant to be closed. Im not 100% but may be worth looking at.

you running the viscous?-is it o.k.? LOL!

lol no viscous fan i've go a new electric fan that went on when the turbos did.

 

ill completely redo the intake system ( remove check and re install) this weekend, and if i can get to them ill fit a spare pair of actuators just to rule them out,

 

but then i think it only leaves the turbos.... :blink:
