Going Air to Water and need to know how to calculate what size intercooler is needed. The coolers are sized according to CFM. How do I calculate the amount of CFM going throught the system?

Engine is street ported and the turbo is a Precision T76 with a billet wheel, will be running up to 20lbs of boost.
