The 4400 to 4800 rpm figure at 45-48 mph for the 2.0 liter
air cooled vanagon is obviously just a misprint or typo.
The figure would be about 1,000 rpms lower.
Like maybe 3400 to 3800 for 45-48 mph would make sense.
That engine has its maximum horsepower at 4200 rpm, 67 hp.
Maximum torque 3000 rpm 101 ft. lbs.
