Test Results
And finally some test results. That's a lot of information for a vehicle that probably nobody but my friend is interested in but I think it's worth collating and recording.

Abstract : The performance and cooling characteristics of the XM-571 vehicle were determined and evaluated. The engine was set up in a dynamometer cell and high ambient performance and cooling tests were conducted at full throttle. The engine was then installed in the vehicle and the vehicle was set up in a dynamometer cell. High ambient performance and cooling tests were conducted at full throttle with a 3-5 mph headwind with solar intensity radiation. Maximum observed engine horsepower was 77 at 3800 rpm. Maximum observed sprocket horsepower varied from 64 to 69 at 3800 rpm engine speed, depending on the transmission gear range. Optimum sprocket fuel consumption was 0.63 pound per horsepower hour. The vehicle at full throttle cooled at 115 F ambient with Code F-84 auxiliary cooling fan installed, the transfer case oil level one pint low, and the engine cooling air exhaust dampers secured open. Maximum engine sump oil and spark plug temperatures were 229F and 394F. Maximum transmission and transfer case oil temperatures were 265F and 270F. (Author)
