Well I cut a hole aprox. .75" x 6" center low in the lower grill block. Water temps dropped 10F and intake air temp shot up to 155F. Whoops,,, Bad hole,,, very bad hole. Damit! And this test loop run only came in at 51.5 mpg. I know it was because of the stupid hit intake air temps.
I will open the hole/slit. up in the morning and see if I can get the intake air temp under control.
Also the outside temp reading was holding at 91F. the snsor is back behind the bumper. It was up as hi as 110F before the hole was cut.
I will get pics Sunday.
