xr6boosted Member 67 Member For: 12y 2m 22d Gender: Male Location: QLD Posted 21/02/16 01:40 AM Share Posted 21/02/16 01:40 AM I had significant overboost on standard BA, eventually snapped a rod as a result. Now I have a BF block and just swapped out the standard wastegate actuator for a Turbosmart 7psi actuator and also a new boost control solenoid from ford. Firstly, this is an absolute pain in the ass job! however I did eventually (after about 8hrs) get it done without taking the dump or turbo off. There are a few things to make your life easier like decent long nose pliers, circlip hooks and I even picked up a mirror with an LED on it to see what I was doing on the flapper arm. I gave up trying to fit a new circlip so I just went with an R clip instead.. Seems secure. Anyway, questions for anyone with a Turbosmart actuator; - Did you notice more noise with it fitted? Mine seems to make far more turbo noise now, I've checked for leaks and everything seems secure, it's making boost okay. - Secondly, I set the length of the flapper arm to suit the length of the standard actuator.. Is this correct? It doesn't seem to be limiting boost like it should, it's better than before but still eventually overboosts, maybe the arm length needs further adjusting? If so I'll probably just flash tune and have it done then. The amount of extra noise is significant, just want to check if others experienced the same thing. Thanks.

This is a bit of an art to get right and you need to know what you're doing Link to comment Share on other sites More sharing options...

I must have an air leak somewhere, will redo all pipes and hoses. Im done working on the actuator, will have to be fiddled with when it goes for a tune. Thanks for the responses.

It was hitting 10psi and beyond, then fuel cut.. I started with plugs, coils and solenoid clean. Snapped rod before I could get to the actuator.. obviously it's a bitch of a job and I've been putting it off. Not sure if I have the emotion energy right now to take it all back apart just to shorten the arm by a few mm. Link to comment Share on other sites More sharing options...

Hey Bud, - More noise as in flutter noise or spooling? ( your over boosting issue may be attributed to a shut actuator, or even a overboosting turbo. Now that's its running right, the turbo sounds like its actually working.) - The box it comes with has a diagram of how the arm should be lengthened. If I remember right, its 1/2-1/4 the diamter of the actuator arm rod. Link to comment Share on other sites More sharing options...
