Direct port is more for cylinder cooling than charge cooling. there is a guy on the aquamist board with 8 nozzles on a 6 cylinder, pre turbo, pre TB, and Direct port. IF you have a turbo in the eff. island and a big IC, then the CC cooling may be more important than cooling a relatively cool charge.

I see what you're saying now, that was what I was saying earlier. The intercooler is working very efficiantly. I'm more worried about combustion chamber cooling, raising the octane and lowering the EGT's than cooling the intake air.

Direct port is not needed. If you were really concerned about it you could tap 1 small D01 nozzle in the aft portion of the intake facing forward. As well as your D04/M04 in the uppipe.

IMO you don't need to worry about it. If you had an inline 6 then maybe.... I would just use the single and plumb it 6" or so down stream of the TB.
