If you're driving in weather that allows stock cooling to get into the 90* neighborhood, it's too cold to use the power anyway. Of course, a strip dedicated car is something else.

I wouldn’t be worried about 138. Cooler air going into an engine is always better, even if timing isn’t being pulled, but to what extent when we are talking about water temps is sometimes argued. In my case at ~1400 RWHP, warm water to ice water was worth only worth 27 RWHP on the dyno.
