You never did actually refute my claim that CFM is far more important than Manifold Pressure.... So, I ask you this can you disprove these simple facts:

Let's say I have a turbo/super charger hell a monkey with large lungs pushing the following air into my intake under the following coniditions:

Manifold Pressure- 1.0 PSI gauge
Normal Volumetric flow at this rate is 400CFM
Air Temperature- 73F ambient outside
Let's say that charge entering the intake is 130 degrees after the intercooler.
One turbo is increasing this to 450CFM
and there other is increasing it to 475 CFM...

Why will my x turbo at 475CFM flow rate with increase the engines ability to produce mor epower at the same rpm or not when compared to the turbo y flowing 450CFM?
