Hassan Posted January 26, 2013 Share Posted January 26, 2013 Hi im having a over boost problem. Ive got a RRing in the exhaust and a sards cat. But its still boosting to 1.6bar. All hoses are in good condition and connected. Link to comment Share on other sites More sharing options...

Hassan Posted January 26, 2013 Author Share Posted January 26, 2013 Thats what i think aswell its the boost gauge. I need to get another one to test. If its not that what else could it be? The hole in the rr was 2" i belive. Link to comment Share on other sites More sharing options...
buster Posted January 26, 2013 Share Posted January 26, 2013 Are you running a boost controller as well as the Rr is not always spot on as in a no two cars are the same Link to comment Share on other sites More sharing options...
Hassan Posted January 27, 2013 Author Share Posted January 27, 2013 No boost controller Link to comment Share on other sites More sharing options...
Swampy442 Posted January 27, 2013 Share Posted January 27, 2013 Unless you have a wastegate or boost gauge issue then it shouldnt be possible to push 1.6bar Link to comment Share on other sites More sharing options...
Benjy Posted January 27, 2013 Share Posted January 27, 2013 UK or J-spec? Link to comment Share on other sites More sharing options...
Hassan Posted January 27, 2013 Author Share Posted January 27, 2013 J-spec vvti. Can a dumpvalve cause any issues? Link to comment Share on other sites More sharing options...
buster Posted January 27, 2013 Share Posted January 27, 2013 Time to invest in a good quality electronic boost controller bud will keep the boost regulated Link to comment Share on other sites More sharing options...
Hassan Posted January 27, 2013 Author Share Posted January 27, 2013 Ive got a blitz one will install it and see how it goes. Link to comment Share on other sites More sharing options...
Swampy442 Posted January 27, 2013 Share Posted January 27, 2013 A dump valve doesnt control the boost pressure. Chance the boost gauge first and see whats what, and dont cane it too much, if it is running 1.6bar youre gonna have problems! Link to comment Share on other sites More sharing options...
Hassan Posted January 27, 2013 Author Share Posted January 27, 2013 I know it doesnt control boost but i read it somewhere that dumpvalves are known to cause boost issues on vvti engines. Well i will try a new gauge first and see what happens. Link to comment Share on other sites More sharing options...
Benjy Posted January 27, 2013 Share Posted January 27, 2013 Just fit a boost controller and see what that says. If the controller and boost gauge agree with eachother, there's no need to buy a new boost gauge is there? But yes. 1.6bar on ceramics = turbo's likely to sh!t themselves.

Hassan Posted February 1, 2013 Author Share Posted February 1, 2013 Ive not had a chance to fit the boost gauge yet. But was wondering would overboosting affect my afr? Since they are stable. Link to comment Share on other sites More sharing options...
Hassan Posted February 9, 2013 Author Share Posted February 9, 2013 Problem fixed. Its a faulty boost controller. Installed a boost gauge and its max out at 18-19psi which is bang on for a Tom's ecu. Link to comment Share on other sites More sharing options...
