So I'm helping RyanC get his engine started today - fully rebuilt 1341cc g40.
It's running but there is no boost. The actuator doesn't move, and the boost gauge is just reporting vacuum.
We are both tired so any suggestions welcome about what silly things it could be.
Turbo is a brand new refurbished item from CR turbos.
The dump valve is a used item made by forge motorsport. We can't feel any air escaping from it under any condition.
Cheers in advance
Jim and Ryan
