Visited with a fellow rv'er this weekend with an older model,(91) motor home with this engine. Supposed to be around 350 hp with 1400 lbs. torque. Single turbo w/o intercooler. Monitors intake air temp, not exhaust. Must be an older version of their cross country truck engines. Also avg's 13 mpg's at 28k gross. Interesting fellow to visit with. Anyone with comments on this engine?
