Top Speed in my Binz was the "D" of VDO. It was a 70 mph speedo and I didn't have a GPS at the time so I have no idea how fast "D" is. 85-90? Only did it once on a long straight road going down hill in Colorado. 1776cc engine, Freeway flier trans with and aftermarket 3.44 ring and pinion, big nut redux boxes, and 15" rims with tall tires. The bus cruised very nice at 70 - 75 around 3500 rpm. It was built for road trips ---- sammie smith <bugcollections@xxxxxxxxxxxxx> wrote: > My quick calculations: With a stock .89 4th gear, a 4.12 ring & pinion with > stock size tires (27 1/4" diameter) and no redux boxes a bus would be > traveling at 88.57 mph at 4,000 rpms.
