Hey all does any know what pressure cap goes on the header tank at the turbo? A friend gave me a new cap it has 0.9 on it but I've read somewhere it needs to be 1.9? Any help would be great its in for test Friday night!
 
Sorry I ment 1.3 bar stupid fat fingers! Thanks lad I'll throw the new 0.9 bar cap on as its safe to do so thanks lads!

Its not an upgrade etc.

0.9 is factory.

Its a failsafe as such valve release if pressure exceeds.


Upgrading to 1.3bar STi one

Means failsafe limit is increased. i.e. track use where pressure may increase on factory set up
