We drove the bus from San Antonio to Houston - about 160 miles. The bus was governed at 50mph - what a slow trip. I brought a truck driver friend that's familiar with diesels and air brakes. We did a couple circles in the schools lot, tested the stopping ability of air brakes.
The few pictures are from pickup and when we stopped at McDonald's.
While driving I noticed that 50mph we are running at about 1750 to 2500 rpm. 1750 down hill, 2500 up hill. On level, we sat at about 2000 rpm. Based on that, can someone guess the axle ratio is and weather it should do 65 once the governor is increased (we'd like to govern at 70 so we can pass when needed).
We'll be pulling the seats out this weekend.
