The turbo spins from flow, not pressure. Now I agree that it creates a restriction that can cause back pressure in the exhaust between the turbo and the exhaust valve. I am just curious how much pressure are we talking about here?

I thought David (125 shifter) was monitoring both banks on his efi single turbo as he seemed to know when one side was running lean.

Turbo semantics aside, I had not heard that an o2 sensor would not work in a pressurized area. Not saying it is not true, but I am curious as to why and where I can read up on the theory.

Cheers
