i changed the current limiter from 200 to 150 just before that run. could that cause the motor to heat up?how?

Not exactly sure and there could be a few causes to reason.. FG101C may be on the right track regarding the center diff in general.

I've stated elsewhere about the heat generated through the use of a center diff that unloads quite often on my heavy vehicles. Mike countered that the sharp angles of the drive shafts are the reason for excessive heat.

In either case (or perhaps both combined), the motor mount transfers that heat as well. I'm sure that would contribute to overall high motor temps.

Patrick from Castle can chime in on the efficiency curve of the 2028. In my XBE for example, a 1520 runs cooler with the relatively tall stock gearing (~50mph) than a 1717 does. Hard to fathom at first, but then CC released info that the 1717 seems to "brick wall" after certain rpm's in terms of efficiency.

Regardless of the cause, I go for the lowest temps possible and 200f is pushing it. Sometimes a little trial and error is in order to find where things seem most comfortable.
