Actually Mike,

logic would say add another radiator. However in my experience the overall temp is still well within the same range as stock. Where you could expect excessive, if not fatal heat, is in the combustion chamber exclusively. An extra, indirect radiator won't really help there.

I have EGT (exhaust gas temperature)sensors, the best indicator of cylinder temps. Mine is well within normal operating temps with the recommended 4-5lbs boost. Were I to up the boost, inter-cooling, probably liquid would, more than offset added heat of the super charged, compressed "charge"by calculation (automatically with the proper controller setup).

As to beefed up bottom end and the like, It does sound desirable but I suspect the cost would be about the same as a good 3.6l. I say blow up the 2.5 if it going to (I doubt it) and then replace the rubble with a 3.6l…a push.

Regards, pk
