I was thinking of moving my vortech oil feed line from a t-d connector on the side of the block (shared with pressure switch),
to the back of the intake manifold. Was gonna run a hard line from there to the front, and then a small hose?

Reason? I think the headers are heating up the hose and the oil a lot. My air outlet temps are like 170-190f.

Any comments?

All that heat is not coming from radiant heat from the headers. Your temps seem pretty decent. The increase in temperature is both from compressing the air (ideal gas law) and also the action of the compressor heats the air (adiabatic effiency). All air compressors suffer from being quite inefficient. On turbos (not sure about s/c but its probably close) the efficiency is around 75% maximum. This means that only 75% of the energy put into the system is used for compressing the air. The other 25% is generated as heat.

In either case, I dont think re-routing the oil feed is the way to pursue this. I would look into getting an intercooler (if you dont already have one).

 

Not exactly. Even with 100% adiabatic efficiency, air temp would still rise when you compress it. What you're really talking about with adiabatic efficiency is how much additional heat is added by compressor inefficiency.
