I have recently fitted the forge blow off valve to my AGP Esseesse and it makes the blow off sound but it is accompanied by a wierd Mettalic ping/Squeak.

I know there are different springs available for different psi of boost (im currently running 21.75) and some guys on the punto enthusiast facebook page have suggested changing the springs.

Anyone else encountered this on say the 500 Abarth and solved it ?
 
Did you manage to fix the squeaking noise. Just wondering because mine does the same and don't know how to fix it.
Thanks Andrew
 
Yeah i think me and forge concluded that there was not enough space for all the air to be released at once so what happens is air is rushed out so so fast it whistles.

The solution was to put the valve from the Renault 5 turbo on and now that works a treat.

Give them a call they are really helpful ?
 
Thankyou for your reply I've been trying to get intouch with forge today emailing them and phoning them but to no avail. Can you please send me a link to what valve you mean so I can try and source one myself.
Thanks Andrew
 
It's Sunday so they won't be there, leave it till Monday, I will try find it but you will get one off then for free if you get into contact with them and are willing to try a few different things ?
