dangerous brain Posted May 18, 2008 Share Posted May 18, 2008 OK if I didn't see it myself I wouldn't have believed it. Today monsignor G came to mine and tuned my ailing beast. We had quite a lot of issues. One of which was the boost gaining very very fast to the point it was uncontrollable. Lets start at the start. We pulled off the pipes to the ageing HKS EBC solenoid. We plumbed it into the Apexi boost solenoid. It spooled so hard and fast it hit boost cut in nano's and was undriveable. So we headed home and by-passed the solenoid so it was waste gate only, same sh*t. On low throttle pulls the boost would climb to 1.3-1.4 bar. Put the pipework back on the HKS stuff and it works great ie back to 1.1 bar question is how the f*ck is it doing that? If it has a 1.1 bar spring in the waste gate why is the car overboosting? If it has a 1.4 bar or higher spring how is the HKS doobry pulling the boost down? Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted May 19, 2008 Share Posted May 19, 2008 Maybe you have a split pipe somewhere? Exactly the same thing happened to me, was boosting way over the 1.2 Im mapped for. Took me an age to find out it was a split hose going to the rear most turbo wastegate actuator, really hard to see unless you use a mirror or strip pipework out of the way. Just an ideas Quote Link to comment Share on other sites More sharing options...
