2013 Explorer Sport DYNO RUN

[TheMustangShow]

Put the truck on a set of linked rollers for some baseline runs.

Looks like they are putting down STOCK, what FORD advertises.


Here's one run, SPORT is bone stock, save the BFG KDWs.

Whatt?? can you explain your message?
"Looks like they are putting down STOCK, what FORD advertises."
Isn't FORD advertising 365 hp / 350 lb ft ??
I see 300 lb ft on your readout. is that Rear wheel vs Crankshaft? or am I missing something else.

A general excepted rule of thumb Dyno run would show about a 15% drop from advertised crank horsepower/torque to actual rear wheel reading horsepower......so 365 hp/350 torque should show on the dyno somewhere around 310/307.....I'd say you and Ford are in the ball park. Lot of things effect the readings, type of dyno, temp when run, etc. etc......

You're "missing something".

Drivetrain loss is higher in 4wd vehicles, Ford is bang on with their HP ratings, but they are tuned very lean up top from the Factory.

Either the numbers are "bang on" or the AWD system efficiency is garbage. a 24% loss when it operates mostly in FWD is pretty bad.

Thanks, PLUMBAGO,
That's kinda what I was fishing for;..was the Dyno showing Rear wheel HP where FORD would be posting Crankshaft HP numbers. the original posting Video wasn't clear. Sometimes DYNOS filter in the adjustment for rear wheel vs Crank and I was just asking the question: was this apples & apples or; "what is the accepted % loss". Thanks again.

The video says RWHP so I am assuming it's just reading HP from the rear wheels and not the drive train overall. I am assuming a lot of the power would still come from the front.

That an error, should have said AWHP, the Dyno it is on is a linked dyno, the power reading is reflects the All wheel drive system.

I disagree with the efficientcy being 'garbage' statement but only because the shop I used for my dyno runs (GMG Motorsports in Costa Mesa, CA) has been tuning AWD vehicals for many years. The techs there tell me they EXPECT up to 30% loss on AWD vehicals. GMG was primarily a Porsche/Audi tuner shop but with the relatively recent popularity of Subaru WRX's and Mitsubishi Evo's they have been tuning those as well.

No vid but here are my dyno scans, the lower power run is 'stock' save for Airaid CAI and larger tires. The other run is with the LMS motorsports 93Octane high boost V3 cal flashed in between runs. The disclaimer here is that cal was set VERY RICH for supporting mods, downpipes, full exhaust, big intercooler that HAD NOT been performed yet. I had just gotten the MyCalibrator tuner and only had one day to play with it. I do have the exhaust done now and will make another visit to GMG when the downpipes are built.

Maybe it is that bad, just seems more then what most people expect. The power you picked up under the curve is awesome.

Correct…I used the same Video Editing template as for my GT500. AWHP is what should have been noted…but I'm sure most can figure that out...

One thing to keep in mind is that the HP and Torque numbers Ford advertises were achieved using 93 octane gasoline.

For what test, Ford's Benchmarks?

"So it would be safe to estimate the drivetrain loss as a percentage range, say 17-25% for AWD cars."

That's a pretty wide range...
