I'd be curious to see it tested, I think pressure drop will be more substantial once you start extracting heat from the exhaust... cooler = more dense, more pressure to move it.

FYI - the pressure drop of intercoolers and radiators is tested under 0 thermal load. the temp going in is the temp going out, minus ambient air changes. In other words, while being tested, it's acting as a free air radiator, but not as an intercooler.

Edit - Darin posted awhile back on wattage required by the alternator for his car - yours is probably higher. I'd say at least 500W to cover all bases, but I'd worry about making it work, first.
