hate to tell you but your IATs number are pretty much the same as a car with one large front mount heat exchanger and a meziere pump in 60F ambient. On a 40F day you crusing IATs should be 60 and WOT should be way lower than 160F. I think you will need an additional pump in the back to push the fluid into the s/c. I think the fluid is not moving fast enough.
You can split the cooling system there is a DIY thread.
Try not the use tha aux battery, open the ECU box and tap into the orangish wire all the way at the end of the box to get a switched 12v.

Wouldn't the air (that passes underneath the car) increase temperature before coming in contact with the rear mount heat exchanger?
What I mean is the exhaust system is extremely hot, I'd expect that to increase the air temps that reach the rear mount HE.

Just throwing it out there.

They would instantly go back down to 100* and then trickle down to 90ish after a few minutes.

I agree 100%. There is just to much volume to push through the system by one pump and the endtanks on the rear intercooler are also a bad design for slow moving fluids.

I think that maybe just adding a 2nd pump will make a decent different in temp drops.

Thanks Shardul. I thought the recovery was almost instant, so I don't think cooling the liquid is the issue, although I'm gonna seal the edges of the intercooler a little better to stop air from just going around it. I do think I need to look into another pump, and make sure I dont have any kinks in the hose. I had a couple places in the wheel wells that the hose didn't like to much.

thanks for the info on the 12v in the fuse box.

The recovery sounds fine because you have cool liquid ready to move into the intercooler, it's just moving to slow to keep the heat down while the SC is putting down the power. Another thing is that there is a limit to how big the heat exchanger can be before the intercooler becomes the problem.
