Psi/Boost question and the relationship with hp
I'm trying to understand something and want to get the facts straight.
If I have a 2.0L motor with a T3/T4 pushing 6psi and another identical motor with a GT25 pushing 6psi will the hp output of the motor be the same?
Meaning: Is 6psi of boost equal to the same hp from any turbo?

Re: Psi/Boost question and the relationship with hp (k-series)
No, it would be different. All other things being equal except the turbo:
Two different compressors operate at two different efficiencies.
Two different turbines have two different amounts of restriction to the exhaust flow out of the engine. They are nalso rated in terms of efficiency, but not as commonly.
The turbine runs the compressor, so flow across the turbine effects the flow output from the compressor.
All these things impact power output to a greater or lesser extent.
