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.

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.
