Help me understand wastegates/psi/turbo
If I have a 8psi external wastegate spring...
Turbo A is a small T25
Turbo B is a big T3
If both use the same external wastegate... will the wastegate open at exactly the same pressure's in the manifold? Is it as simple as - just that the larger turbo makes more horsepower at the same pressure?
I don't quite understand
thanks

If everything is correct otherwise, yes. Internal gates can be picky. Usually mechanical problems, not the can.
Boost is a measure of resistance. Might be the cylinders didn't clear because you have a small turbo and lots of exhaust pressure. This will show as more boost and will have a lower VE, or less power.
A bigger turbo has less exhaust pressure because the turbine is bigger. The engine clears the exhaust out much better. 8PSI in the manifold there means a lot more burnable **** made it into the cylinder, so it makes more power. Turbo is probably also spinning slower making less heat, too. Still pumps more air and air is power.
