But yep its down on power and boost is all over the place and cant make as much boost as it did before.Boost is up and down then holds it steady (but low)So its either actuator? or turbo or mani bolts??? (I'd think I'd hear that) (but you had that too did you Mika and didnt notice?)cheers for all the positive feedback in here and things to look at fellas.And piss off to all the useless muppets that jump to conclusions.:D :D :DMick←nope, he couldnt tell until it was opened up... if the bolts are missing or lose you wont hear it... it just drains the power and it wont hold boost as commanded. He had a 40 rwkw gain when bolts were replaced and tightened.cheers Edited 02/12/06 06:46 AM by jetute Link to comment Share on other sites More sharing options...

However, I recently did some troubleshooting on another T with boost issues. The problem with that car was the lack of response under 3500rpm but no issues with peak power. You could see on the dyno graph exactly when the power shot up.As it turned out, the car had a 8psi actuator installed but there wasn't enough preload on the wastegate swingvalve assembly. What that did was allow the swing valve to remain partially open causing the exhaust gases to bleed-off through the wastegate port, starving the turbine wheel of the gass it needs to spin. Hence the lack of response down low. Link to comment Share on other sites More sharing options...

The car would not have needed the actuator change but since we were there.....Just waiting for the clutch and surge tank now so we can finalise the tune. Hmmmm all that grunt on pump fuel. On tap all the time and not just till the bottle runs out. Link to comment Share on other sites More sharing options...

wrxkilla Member 106 Member For: 18y 6m Posted 03/12/06 05:41 AM Author Share Posted 03/12/06 05:41 AM (edited) yeh mate, thanks for that.im thinking it will be the tubi or mani bolts.only one way to find out. And it doesnt hurt to throw in a $150 actuator in there at the same time that will help with boost control alot better to redline...cheersWill post more when I find out more for anyone intrested following the thread.Michael Edited 03/12/06 05:42 AM by wrxkilla Link to comment Share on other sites More sharing options...
