He advises compensating for the lack of air flow with a greater core size, which just doesn't seem possible w/o a turbo tail. From the max measurements I have taken for an intercooler, the corresponding attainable air flow is 548 CFM. Gerhardt seems to think I would need closer to 700, but even then my core size should be larger due to lack of air flow.

My question is this: Is something better than nothing? Gerhardt said that with 548 CFM, the intercooler would have about a 2.5psi drop @ 400 rwhp. What do you guys think?
