a trick to help spool up is to go little smaller from the turbo to the IC, then a step bigger from IC to manifold....kind of a venturi effect.

This is on a supercharger, not a turbo....a supercharger doesn't 'spool', so that would just present a restriction.

If at all possible, run the same size tubing as the outlet on the blower.
