Running a WAI through the wringer

[FrugalFloyd]

Wednesday's high temps worried me, too, but the coolant temp alarm light only went on about 2 miles from home, and only stayed on about 1/4 mile. When the temperature alarm kicked on, I was accelerating up an incline. I immediately slowed down, and the light went off. I coasted most of the rest of the way home. I checked the coolant level the next morning and made sure it was normal.

Ambient temps dropped to 80 yesterday and today, and the xB showed normal coolant temperatures of 204 degrees. I did some more BAB testing of the WAI at 55 mph, cruise-controlled, on a 9.9 mile loop to even out hills, wind, etc.

First I ran a B test with the WAI connected.

          IAT/FIA    FWT    mpg
----------------------------------------
B (WAI)    118.4    204.8    41.6
A (ctrl)    91.4    203       42.5
B (WAI)    127.4    201.8     42.8

Once again, no benefits from my WAI.

All this testing didn't hurt my mpg. I averaged 49.0 mpg for the tank, 518.4 miles on 10.575 gals.
