Was able to meet my year long goal of beating 90 MPG on a commute to or from college. 704.6 miles at 92.3 MPG, and the 3 gallons remaining should be more than enough to last me for the whole semester. 96.8 MPG indicated for the first half, and about 89.6 MPG calculated for the last half which included mountain passes in WV and VA. Target speed 55 MPH on the highway and 50 MPH through the mountains. Car was loaded full with probably a couple hundred pounds of belongings, so it accelerated slower and climbed hills a little harder, but coasted a bit better due to the extra weight.
Also restored my hot air intake in preparation for winter driving down here. Previously I just had the U-shaped intake piece pointed toward the back of the car that kept temps about 15-20 * F above ambient; this one utilizes in addition the hose piece from the intake resonator that I deleted, and reaches to about 3-4 inches away from the catalytic.
Intake temps are now about 25-35 * F above ambient depending on conditions. Intake temps fluctuated between 89 and 118 * F, but there were brief moments on some long hill climbs where temps rose to close to 140 * F. On one long grade I did have to exhaust hot air into the cabin (with the windows down, of course) due to the coolant reaching 220 * F. This is with the full lower grille block / no upper grille block that I have been running on the Insight since I bought it.
