So when replacing a supercharger with a larger unit, manifold volume should be increased.... but how does one calculate how much? I certainly don't know... hmmm...
Manifold Volume / Supercharger Displacement

How do you increase intake manifold volume? Phenolic spacer?
I've always seen manifold volume calculations based off engine displacement not charger size but d

I have read two versions. Manifold Volume is the space from the, 1) MAF to the combustion chamber, and 2) from the TB blades to the combustion chamber. Being that the air travels through the supercharger between these two points, regardless of which you subscribe to, I would think that a bigger blower means more volume....
Not quite correct. Using a Centri or Turbo for #2 the Blower/Turbo is outside these two points. It goes through the turbo/blower and then to the TB Blades.
There is no concensus on the definition as stated previously, so how would you go calculating what manifold volume "should" be when making this change?
