I know ScottWS6 has maxed his out, hes right at 600rwhp with an F1 head unit on top of a 348c.i. motor............I'm pretty sure mine will also be close to being maxed with my D-1SC on top of my 372c.i. motor.......
But we will see..........
Thats where the front mount griffin intercooler comes into play............

your right on NOGO, mine where maxed out a while ago. My AIT are at 187 degrees. I am currently getting the tranny fixed and wil be upgrading the innercooler to the same at prostock johns. I have a 5 psi drop right now. I look forward to 90* temps and 3 more psi. Hopefully I will be in the HP range of PSJ

Intercoolers are usually rated for a certain pressure drop vs flow. Usually rated for 1 psi, 1.8 psi, or 2 psi. You have to check with the manufacturer to see how they rated it.
ie: A 1400 CFM intercooler should flow 1400 CFM with ~2 psi pressure drop across the core.
If the DP across your intercooler is greater than 2 psi, then you have maxed it out. Not only does this cut the amount of boost that you will see at the manifold, but it will also push your air intake temperatures up. The undersized intercooler acts as a greater restriction to the blower than necessary and as a result, blower discharge pressures are higher (even though the manifold ie 'boost' pressures are lower). The higher the blower discharge pressure the greater the intake charge temperature.
So, an undersized intercooler is a double-whammy. You get higher intake temperatures than desired and lower boost pressures (at the manifold).
Properly sizing the intercooler is key. If you don't properly size your intercooler you may be better off without it.
