Re: Intake air temperature
After a car show in 100+ degree heat I got an inspiration (better late than never). Why not just create a heat shield for the air intake components to insulate them from the very hot air under the WK2 hood!
I was easliy able to cover the intake tube and top of the air box; see the attached photo. Reflectix has thermos-like separation that may be used for applications up to 180 degrees, and the measured temps are well below this value. The insulation coupled with the hood design that forces the stock intake to use cooler outside air sounds promising.
I took a road trip and after several hours of highway driving the intake duct was the temperature of the outside air. This may have been true before adding the insulation, but I can remove it and run a "before" test.
