Honking sound when coming on boost ?

I have had this from the start but dont know what it is . I have been told that it could be the check valve for Brake booster / clutch ?

Does anyone know what im talking about ?

 

Thanks Mike , I thought the weird duck sound you hear when you first take off from the back was the goose honk . Thanks for clearing that up

So can I get aftermarket BOVs that fit on without too much modification ? I dont want the pfffffsssshhhhh sound either lol

 

Maybe your zed is just honking because its horny?

Nothing too worry about, it's just you hitting the horn when thrown back into your seat with the g-force from hitting the boost on your TT's

 

Will it hurt to block them till I sort something out ?

 

Has anyone done this ? are the new ends for this kit just pressed on ?

 

Blocking your ears will be fine.

 

Ha ha , sounds like a dying cow under the bonnet
