I still have a stock radiator, with my procharger, 8rib and mark 8 fan (which I had to trim down the shroud) theres no room for a bigger radiator unless I go customer and have it offset so it eats up the room between the ac condenser and the radiator. All my changes did seem to help but I got it all wrapped up around the time it started cooling down some around here so it wasnt a completely accurate comparison

the 3 core/3 pass sounds like a reasonable theory, the only reason I can see why it might be entirely accurate is it may be that our current radiator might be capable of more as it is but doesnt have sufficient air flow/volume. The extra capacity and some gain from 3 pass may be part of it but it sounds like frequently guys who went bigger radiator just had a bigger window before it ran hot.
