On the G.P. Abarth there is a small vent that is capped off to accept a dump valve that will make your car make the "woosh" noise when you change gear. Chunky has had a quick look into this but the e-mail he sent to Turin appears to be a bit "lost in translation".
Has anyone looked into this and if you have, did you manage to find one that would do the job?
We are a bit busy to do any thorough research into this at the moment, but if there was any interest I may be able to get the service department to dig a bit deeper.
Before you get too excited, bear in mind that it may well cost between £350-£500 for the upgrade and wont make a huge difference to the performance.
Let me know if you've got any interest?

Here you go..

Aren't recirculating dump valves better for performance though, as with a atmos valve you get more lag between gear changes?

That was alway the case with Punto GTs anyway.

Not great videos, but it shows its been done!...

that was the strange thing though, the GPA has a recirc system, like you said the excess turbo pressure deflects off the throttle butterfly, up the bypass hose, and then there is an electric recirc valve. once this is opened the pressure is guided back into the turbo air inlet pipe by way of the pipes that run around the top of the engine cover.

what i couldnt understand is right next to the air intake pipe/intake throat on the turbo there is a triangular hole, vented to atmosphere, with a drilling that leads into the throat. this triangular hole has to be blocked off when the ss kit is fitted by a triangular plate with a couple of seals on it. this plate is marked dump valve kit in the ss kit.

is it possible then that the gt1446 is designed for a system that had a dump valve venting to atmosphere, and because the GPA has a recirc system, its blocked off as its not required? could you still fit a dump valve to the turbo to make it go ptchh between gear changes, or is this impossible on a recirc system unless you want to start leaving pipes disconnected and block others off?

it seems to float quite alot of peoples boats though doesnt it?!

£300-£500 just to sound like a 1993 Impreza? I'll pass thanks!

It would be amusing for about 20 min then would become a little tiresome.

agreed... maybe the first time in a town to show off and the it would get annoying and you'd start looking like a t*t... its not something id want on my car but as you say chunky it does float quite a lot of peoples boats...
