Default Re: intercooler cfm

CFM = [rpm * displ of one cylinder * Number of cylinders / 2] / 1728

so

6500 RPM = 611 CFM
6000 RPM = 564 CFM

Some intercooler manufacturers recommend using 1.5 CFM per every horsepower when it comes to proper sixing but the calculation above should be a good estimation of actual airflow.

HERE is the graph of the Lysholm 2300AX, the SC you have. On the graph, spinning the supercharger to its peak, you will see around 1100cfm. On intercoolers, you want to get one that flows the most cfms with the least amount of pressure drop, that you can fit in front of your radiator or wherever. Check out www.turboneticsinc.com and look for the Spearco intercoolers. Spearco is some good stuff.
