Do you mean coldest now or winter? With no asshattery, normal driving it sticks to 165-175 or so in similar temps.
Coldest in the winter that I can remember was 138 when it was about 25*F outside. No asshattery, just normal driving.
Not sure about torque. It's a typical stage 2 set up running at about 18PSI on a Perrin TMIC. Cooler is a TruCool 4452 and I'm running 100% Amsoil (had a flush done). Also have an IPT modded valve body.
