S4 Koyo WITH corksport fan shroud and low mile OEM viscous fan. Custom ducting for RAD and OIL COOLER off of the FMIC.

My temps at idle with brand new OEM water thermo sensor and prosport gauges: 80*C/176* F

Cruise/light load: 78*C/ 172* F, sometimes 77* C if above 40mph for sometime(no freeways in Montana and havent took her on the highway yet to see ducting efficiency)

Constant atmospheric pressure pulls: 80*C

When I actually start boosting I will record results BUT my last motor doing 4-5 constant 4th gear WOT pulls on the highway for tuning, my temps never went above 85* C with the same radiator. MIND YOU this was before my ducting too, ambient temp that day was 62* F.

I really believe in what Brian said about ducting. It works wonders.
