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. Harald '90 westy G.
