Interesting.........
The 160F stat and fan controller rock.
I set the fan even lower to come on at 170.
So far it's been really cool outside this spring. I can't tell how well it will work in hot weather. But at 68F at 80mph it will hold 172F no problem. The fan is making the difference even at speed. I had it set for 175F and it would hold 176 all day.
So, with no other new mods I go to the track last night and my AFRs drop from the ragged edge 12.7 to 11.0 all the way through 3rd. The car felt slower, too fat.
Screaminjoe used a pot on the ECT sensor to enrichen his AFRs.
