My cousin used the have a Skyline which had a dump valve and it made a really nice wooshing noise.

 

I know absolutley nothing about engines apart from the fact that you have to put petrol in it.

 

Is it posible to add dump valves to an Auto TT ...? If so how much are they likely to cost, and would I have to tell the insurance comany...?

And would they make a nice wooshing noise...?

You can get dump valves on an auto, MAC1 has Blitz valves on his auto Z.

The Zed has a recirulating(sp?) system fitted as standard.

I think one Z owner on here(Steve E) removed his dump valves due to bad effects when changing gear at 120mph+(I think he had a manual).
