Just got back from Pompey where Dalhousie & myself pulled the engine out of his Gul Est.
On the way back I did so data logging
Gave it some beans to make sure she was boosting to the correct psi, well yes and no
I can hit 17 psi then I hear air escaping as if the dump valve has opened and as you see from the screen shot boost & TCV duty cycle drop but Rpm and speed are increasing then the boost & TCV increase.
I`m pretty sure the dump valve spring needs to be stiffer to withstand the high boost pressures
I`m I right or I`m I barking up the wrong tree ??
You`ve got to love this data logging
