[QUOTE=Activ8;60461]I thought about this this morning...
We're going about this wrong, our turbos are obviously setup differently. IC pipework etc.. so we need to go back to a standard K14
Just looked up the set-up for the K14. As follows;
Angle a (compressor housing) 265º
Angle ß (turbine housing) 175º
Settings Waste gate (pressure) 0 bar
Settings Waste gate (lifting rod) 3.0 mm
So if you clock the compressor housing on the manifold this will help us set the actuator arm positioning and length to wastegate.
Might be worth measuring the length of the actuator arm in case its been borrowed from another turbo?
I'll compare later tonight as I'm out and away from home.
So, I read 3mm as the balance of thread at the end., this should now be 0 bar and a closed wastegate.
If at engine off your wastegate is open I think we can assume that its bent, blocked or damaged. Only 2 weeks until the VolvoK14's fitted.
I'm thinking its not "just" the turbo thats the problem.... 9psi , 12psi - have you de-cat'd the van?
I would read the 3.0mm as the amount of preload wound onto the wastegate actuator lever with 0 pressure applied on the can and the lever in the closed position
No cat fitted.
With the new N75 enhanced map installed the boost does come in harder and earlier - BUT it's still doing exactly as it did before, during constant steady acceleration through the rev range the boost rises with some reluctance to around 9psi, stays there for maybe a second then drops back to around 7 and stays there as you continue building revs, then as you change up and continue accelerating it does exactly the same - up to 9 then drops off to 7.

Thanks for the info - I'll double check
Very tempted to pull the turbo and try to sort it just for my own sanity.
