[L.O.A.]

This dyno chart should help you guys better understand this 3.0 Ecodiesel engine:

these dynos aren't wheel dynos though. probably straight from the crank

A far cry from my '97 Chevy half ton that had 180 horsepower and 360 lb-ft of torque. That by the way from an engine twice the size of the V6.

Yeah likely, as always expect the typical powertrain loss percentage range and you'll have around what it should put out to the wheels.

here is the data sheet and dyno chart for the L630 EcoDiesel direct from Motori's website...

[tugboat]

you can tell they are very different

 

[L.O.A.]

Interesting, thats weird.

 

[tugboat]

different tunes for the diesel ram? different dyno?

These graphs have different units on the corresponding axis. VM Mottori shows power in kW and torque in Nm. The other graph has HP and Lb ft. No worries.

 

[tugboat]

right. didnt look close enough

Can't believe I missed that, good looking out!

waiting for the first wheel dyno. wonder what the real numbers will be

Any guesses?

 

[Anomaly]

Is there a prize for the closest guess?

I think that the drive train is fairly efficient, so...
206 HP
357 lb-ft

 

[Accused]

you're cheating , diesel power did it..

Oh. We would need to run between 3,000 and 3,300 rpm to get maximum torque. Then I look at the Cummins chart and see you are over 2,200 to get into the max torque range. That's different than I remember.

We normally run our Eco engines in the 1,600 - 2,000 rpm range. If that chart is correct we are getting almost no torque and won't until we add another 1,000 rpm.

That Cummins thing also bothers me. I seem to remember my Cummins had the most torque in the 1,800 to 2,300 range. That's way different that that chart.

Wonder if it's right? Just seems like a rather high rpm range to me.

The problem with the power dyno is they cannot floor it in gear without it downshifting into another gear.
So they roll into the throttle till about 3000 RPM then floor it.

The Fiat dyno is more accurate because they can use there software to not allow the motor to downshift when testing.
I did lots of dyno on my Hemi at that was alwas the problem, but luckily on a gas motor low end tq and HP is not there anyway so you did not need a low RPM number.
