Re: DTA 360 info
Something wasn't right with your DT360--one sample isn't enough data points for a conclusion. Mine averages 12+ and has gotten as good as 13.1 on a trip out to Iowa. I think they are nearly identical in everything except weight. The 5.9 Cummins weighs 950# and the DT360 weighs 1,300#. I'm assuming this is because International made naturally aspirated versions of everything and when you are running a farm tractor or industrial engine wide open all the time, the displacement is what determines the horsepower. They probably used one basic block design with minor changes to suit a number of displacements. The internals between the Cummins and International aren't that different. The extra weight seems to be in the block.
