I'm not a heavy duty mechanic.
I'm curious about a dyno report on a truck I'm looking to buy.
The engine is a 2019 MX13 rated at 455 hp. I'm unsure what the rated torque is. It's also mated to a 12 speed automated and 2.64 rears.
Max corrected hp at 1402 rpm was 363 and max corrected torque was 1365 at 1290 rpm.
For those of you familiar with this motor and dyno numbers for it, are these numbers reasonable or should I run?

75-90 hp loss through the drivetrain seems to be pretty typical in most cases from what I've experienced anyways.

A 500HP Volvo D13 delivers around 400HP on the ground with a 12 speed AT2612 direct drive tranny and 2.64 145/40 Meritor rear ends.
MX13 455HP should deliver a 364HP recorded power to the ground.
I hope this help you.Accidental Trucker, MartinFromBC and MicksRule Thank this. -
If 20% is a decent number, 363 should close enough considering any variables in test procedures or test equipment. Does this seem right?
Another Canadian driver Thanks this. -
Back in the day my old man had his nearly brand new Series 60 on the dyno after an uprate to 500 hp. It laid down 411 hp to the rollers.

Sounds healthy to me.

Dyno seems good, what were numbers on the vitals like pressures and temps. I'd be interested in oil sample, trip report and after treatment history in ECM.
Another Canadian driver and MicksRule Thank this. -
Will an oil sample be accurate after an oil change?
Trip report? I do have, at least, a partial ecm report that looked pretty good as far as total engine hours and fuel economy numbers go, but doesn't show any aftertreatment history in it. Is this what you're referring to? I may be able to get a complete report. Actual average speed is slightly better than 42 mph with all idle time.

Looking good if it passes the oil ail. and blow by test in hi gear it seems to be a good motor!
