Speaking of airflow, I think the Contour fans are presenting a little restriction (when they are off) that is more important at low speeds.

I'm thinking of rigging another relay to run them at low speed all the time, and still have the temp switch turn them on full. Either use the nichrome resistor that the fans come with, or a big 1 ohm resistor (both of which I have). That'll also cut down on the sudden load thrown on the alternator when they kick on, which makes idling interesting (non-existent low speed torque with 272@.050).

thoughts?
