Running a WAI through the wringer

[FrugalFloyd]

Did some AB testing of my WAI/CAI today. I'd checked the WAI side pretty thoroughly, but not the CAI side. My setup allows my air intake access to cool air in front of the front fender, so I did some test runs. AIT = air intake temperature, FWT = Fahrenheit water temperature. Conditions were not good, with >30 mph variable gusting crosswinds.

A test: WAI air with grill block 114.8 F AIT, 203 FWT, 48.8 mpg
B test: CAI with grill block 80.6 F AIT, 203 FWT, 48.1 mpg
C test: CAI and ambient air (grill block removed) 69.8 F AIT, 185 FWT, 47.5 mpg

Previous testing showed no significant difference between A&B testing. I may have to repeat AC testing as ACA testing under better wind conditions, to tease out the possible correlation seen today with the non-grill-blocked CAI 1.3 mpg worse than the grill-blocked WAI. It's most likely testing error, but I'd like to neaten the results up. If there is a loss of mpg with the CIA, is it offset by shorter pulse times?

My local Sheriff's Dept. stopped to check what I was doing when I was removing my grill blocks. I think they were more relieved to learn I wasn't a litterer than they were interested in my mpg experiments.
