renfrewshiremod_craig Posted September 2, 2013 Author Share Posted September 2, 2013 Just realised i have described that really badly lol what i mean is i need to get a high pressure cap as when fully boosting it blows by the cap holding full boost i can hear it hissing and when i get out the car the coolent has sprayed all over the wing Link to post Share on other sites
WallaceGlanza Posted September 2, 2013 Share Posted September 2, 2013 The pressure rating of the radiator cap doesn't relate to the boost... however my 1.1 bar radiator cap only started leaking when I started boosting over 1.2 bar Link to post Share on other sites
