We've had competitors from past events become life-long friends because of the Challenge. It truly is a one-of-a-kind event. Jason Sands, Associate Editor of Diesel Power
ATS actually has very powerful vent fans in the back of the dyno cell, which is why the smoke doesn't empty out into the crowd. Also, by the time the smoke gets bad, the truck has usually made peak power, so it doesn't affect the numbers much. Jason Sands, Associate Editor of Diesel Power
Won't the black smoke circulating back to the engine via the cooling fan in front of the truck give less clean air to the engine and cause loss of power and dyno result? They should have a much better exhaust extraction/ventilation system to draw out all that thick black smoke.
The dyno has a 25% correction factor because of the elevation, based upon naturally-aspirated gasoline numbers. The announcer was looking at the "corrected" set of power numbers. We use uncorrected numbers on diesels, because they seem to be closer to the truth. Jason Sands, Associate Editor of Diesel Power
We held it in Bowling Green a few years ago, but we're trying to mix things up. Personally, I wouldn't mind seeing to go back to sea level. Jason Sands, Associate Editor of Diesel Power
A few years ago we had a mostly stock truck with just an intake, exhaust, and programmer enter the challenge. He finished last. Can't bring a knife to a gun fight, so to speak. Jason Sands, Associate Editor of Diesel Power
His big stage of nitrous never triggered, which is why his numbers were lower than expected. They didn't find that out until after the dyno runs, unfortunately. Jason Sands, Associate Editor of Diesel Power
No. The higher the altitude, the less dense the air is. Density of air has a direct effect on power output. High density air means more O2. More O2 means more fuel which equals greater power. The temperature of the air also has an effect on the density. Colder air is more dense.
4:26 Don't confuse everyone, it has an 88mm turbine wheel. The last 2 digits are the size of the compressor wheel. Usually most people are referring to the compressor wheel when they name a turbo by its size. It's a 75mm turbo.
Im a duramax fan but truthfully I like this whole Diesel week show. I like all of these trucks and hearing that 7.3 reminds me of the diesels of yesteryear. It sounded mean and different than the rest.
Funny how far diesel performance has come in just a few years. I have a daily driver 1400/2300 and can turn it down to 1k hp to pull my camper which weighs 13.5 k lbs. I love diesels and diesel performance!
Yes that's correct. Stock diesel vehicles are pretty clean. I was referring more to the vehicles with no emissions controls like the ones in this video.
I also have a tundra as well. A 2010 5.7 l crew max with a trd big brake kit,air intake,headers,fuel injectors and a custom intercooler.Just hit 100,000 miles!
No, gasoline and diesel cool fuel pumps as a side effect. Fuel however, can be anything to provide heat and/or power. Coal can be fuel, but it isn't used to cool fuel pumps.
you told me that your truck had a two compound turbos and two NOS canisters I would of called you bat shit crazy, I have a new found appreciation for truck performance
Funny because I know a 60 year old man who runs a dyno like this almost every day and works with nothing but diesel truck since 93 or 94, he doesn't use exhaust vents or wear a mask of any sort, and he is healthy never had one problem and so are all of his workers
The dynos should be at sea level, because thats where a car truly goes as it can. And i love that tri-turbo F-250. That Paul Cato's truck is strong aswell but its stupid that it wrecks itself.
We have them, all newer trucks have diesel particulate filters, but these are performance engines with far from stock exhaust. They have had anything that could limit performance removed.
Well, I know the older U4000 very well, because I drove one during my time in the army (Bundeswehr). And they have an enormous pull, because the Unimog was originally built for pulling heavy farm machinery (and it is still used in this capacity). And the standard U4000 with the 160 kW engine has maximum torque of nearly 7200 lbs. And a Unimog U4000 in germany costs 70K €, and a new Dodge Ram 2500 costs 55K €.
the cummins diesel is a 5.9L ( or a 6.7) that makes 350-450 horse and 600-850 torque. the powerstroke and duramax are converted V8 motors and dodge just dropped a 4 liter V6 diesel making 250 horse and 450 torque
You are correct. However, I guarantee you that none of the trucks in this video have their stock emissions controls anymore, or any emissions controls at all. They certainly don't have particulate filters, since they're filling the shop with smoke.
Go look it up. There was one for a test show, but they stuffed it for some reason. It was in '08 if I remember correctly. I love my Tundra and the supercharger in it is a beast, but I can only dream of how a diesel version would perform.
Lol I like you... I have owned a few Powerstrokes and Cumins, but my Duramax beats them all hands down. I just payed my 06 off and I'm about to buy an 09 and do some major modifications to my 06.
Very impressing vehicles. Coming from the UK where we don't have these kind of trucks, it was interesting to see them. But I do have to say that it seems strange that the dyno place didn't have better extraction for the exhaust's. but none the less good to see these kind of trucks.
Hahaha what the eff. Ask anyone 5 years ago if Strokers would be competitive with Cummins and Duramaxes would be the underdog they would of called you insane.
If you want to talk sensible numbers on diesels, there's the BMW X5 m50d, a tiny 3 litre in-line 6 that delivers 380 hp, 550 lb-ft and about 37mpg (is very well build, looks good, etc.). If however that is not enough, there is the petrol powerd Mercedes-Benz G65 AMG that has a 6 litre V12 that delivers 610 hp, 740 lb·ft, weighs around 6000 pounds and does 13mpg.......oh and its very luxurious, has top level build quality and prices start at 200 grand.....
It depends on what you are comparing. Reliability? Internal strength? Torque? US diesel is ahead. Fuel economy? Power per liter? Materials innovation? Germany ahead. It really comes down to what you want to compare.
the sound of that 7.3 makes me miss the old diesels, Can MT release a video of just the 10 trucks doing pulls with no words, just one truck after the other. Then repeat
Since they're not ventilating the dyne room I'm surprised they're not standing above the stack with their fist in the air during pulls. Great challenge though!
The high altitude reduces the amount of oxygen in the air. They could run a lot more NOS to compensate but most of them probably wanted to drive their trucks off the dyno.
Those diesels are built a bit differently. They are not quite as heavy duty as the diesels found in these trucks. They would require stronger connecting rods and a new crankshaft to really take the power. The rotating assembly on these trucks in the video can generally take 2000+ lb-ft of torque.
Not trying to hate on my own home turf, but have to give credit where credit's due. A stock 2013 M5 was dynoed at 534 whp, that puts crank hp somewhere around 600 hp. All from a 4.4L twin turbo V8. However, credit where credit's due. Our "big fat lazy" engines are lighter. GM's 7.0L weighs close to the same as BMW's straight six.
No, it's full of stuff like sulfates, silicates, and other stuff proven to cause cancer and serious lung issues. Plus the fine particulate matter is a major contributor to various lung issues. It also produces tons of NOx which leads directly to acid rain, ozone depletion, and respiratory issues. A modern, stock diesel with emissions controls in place is fairly clean. These trucks here are MAJOR health/environmental hazards.
unimogs are insanely good for terrain. and they can pull. its just a consumer point. me being a U.S. faithful, would buy and use the ram, f-250, 2500 HD etc. cause im loyal to the big 3.
That's not true, they never banned German diesel engines in the US, the EPA just tightened up restrictions on diesel cars in the 90s, making it more difficult for imported diesel cars to pass EPA requirements.
Sort of, tire diameter isn't measured. The dyno only measures the force being applied to the drums, the result being "wheel torque." Torque at the crank is always a guess on a chassis dyno because there's no way to measure frictional losses from the drivetrain (trans, rear axle, and tires.) To complicate things even further, a dyno doesn't actually measure horsepower, only torque. Horsepower is another calculation derived from torque.
It's calculated by the computer. The computer takes the speed of the engine, the speed of the dyno drums, and the force applied to the dyno drums and then spits out the torque value corrected for gear reduction from the transmission, rear axle and tire size.
EXCUSE MY CAPS LOCK. JUST WANTED YA'LL 2 KNOW THAT IM NOT YELLING OR ANYTHING, BUT IM CONFUSED BOUT THE FIRST TRUCK THE FORD I MEAN WAT IN THE HELL IS THE DEAL WITH THAT FIRST GUY, WHAT I MEAN IS BEFORE HE DYNOED IT HE SAID HE ESTIMATES THE HORSE POWER TO BE AROUND 865 AND THE TORQUE TO BE AROUND 1600, AND IT ENDED UP MAKIN' 856HP AND 1700TQ AND THEN HE SAID THAT HE WASENT HAPPY WITH IT AND ITS NOT GOOD WHEN THE TQ WAS WAY BETTER THAN WHAT HE WANTED AND ONLY 10HP DIFFERENT. I MEAN WAT THE HELL!!
Yes, I realize unfiltered petrol/gasoline exhaust also contains poisons and carcinogens. The list isn't nearly as long as diesel exhaust though. I should make it clear that with the proper modern emission controls both gas and diesel engines are quite clean. However, diesel engines with no emissions controls (like the ones in this video) are very dirty.
my 5.7 is super charged and was rebuilt 30,00 miles ago, so its still new. and im pulling over more flat terrain. and ive only moved 20k lbs 1 time. my fuel pump quit 2 days later. it definitely didnt want to move that much weight.
First guy on the dyno the guy says his power and torque through the window too him 856hp and just over 1700lb.ft.. and then is displays like 1397 later.. wth? Shit editing.. lol

I get the whole roll coal thing, but it would be nice to watch the dyno runs. Connect the exhaust hoses for crying out loud. Love the series!

Sorry for the wait guys. Day 2 just went live!
Don’t worry... I’m 7 years late 😂
"Hey let's put the dyno in the back of the shop with no ventilation".
3rd time watching, from start to finish.
I know me too! I've watched all of these like 2 or 3 times

Rizzi and Woosley look way more excited to be there than anyone else.
I love all these guys personalities. Very kind and respectful of everyone and their trucks.
The 6.4 predicted 865 and 1600, gets 855 and 1700. “Not what we thought or wanted”
i had no idea that these engines could make that kind of power. very impressive.
dyno day=lung cancer day
who the fuck cares, go fuckin drive a prius then!
MultiSniipez it was a comment on how they all stood there lol dont get your panties in a bunch
MultiSniipez who cares about health!!!! you are so intelligent!!!!
lol @ angry truck owners
I don't know why they didn't have a door by the Dyno haha. Pretty un healthy and i'm a truck guy.
The new "American Muscle"!!
Happy to see a 7.3 still competing with the new guys! I drive one everyday and love it!
Our Diesel Technician students would LOVE this!!

love MotorTrent because they provide diversity of automotive culture. everything from Hi end exotics to hot rods and now diesel trucks.
Great job
Im a duramax fan but truthfully I like this whole Diesel week show. I like all of these trucks and hearing that 7.3 reminds me of the diesels of yesteryear. It sounded mean and different than the rest.
he said 355.000 miles on that GMC, that is like 572.000 kilometers. wow!! he sure takes good care of his vehicle.
Funny how far diesel performance has come in just a few years. I have a daily driver 1400/2300 and can turn it down to 1k hp to pull my camper which weighs 13.5 k lbs. I love diesels and diesel performance!
was thinking would be a 5-10 min vidz..20mins AWESOME!
Those things don't fuck around what so ever, cool video and good host.
That 7.3 should have adjusted his tune for the altitude it readlly does make a hella difference!
Bandimere Speedway, grew up about 5 miles from there. The torque the trucks produce is crazy.
Yes that's correct. Stock diesel vehicles are pretty clean. I was referring more to the vehicles with no emissions controls like the ones in this video.
"I don't know what to do with my hands." Will Ferrell quote in the deleted scene at the end is perfect!
I also have a tundra as well. A 2010 5.7 l crew max with a trd big brake kit,air intake,headers,fuel injectors and a custom intercooler.Just hit 100,000 miles!

needs more sponsors. This stuff should remain in SpikeTV

Hell yes!!! Why doesn't Diesel Power Mag have its own regular show on the MT channel???
The truck that came in second on the dyno had the least smoke, that man knows the benefits of good injectors.
The dynos should be at sea level, because thats where a car truly goes as it can. And i love that tri-turbo F-250. That Paul Cato's truck is strong aswell but its stupid that it wrecks itself.

im pretty sure this is the environmentalists' favorite series
Powerstroking their Duramax's before Cummings in a Holset.
The American pick up truck hasn't been the same since "Brokeback Mountain". ;-)
This is why I love America!
Those rams are killin' it
One Cummings breaks and the others had to use nos to get good numbers lol
Chris don't let Wyoming down! I woulda came with my 95 ford f250 with the 7.3 but I didn't know about it till nowXD
that cooling fan is just recirculating the diesel exhaust back into the engine intakes. Not good for power
Even the lowest number is still like what the fuck?!?!
and that is the reason why the most economical ones are still banned.
Lol I like you... I have owned a few Powerstrokes and Cumins, but my Duramax beats them all hands down. I just payed my 06 off and I'm about to buy an 09 and do some major modifications to my 06.

Ask anyone 5 years ago if Strokers would be competitive with Cummins and Duramaxes would be the underdog they would of called you insane.
I'm with you on that nothing sounds better then a small block wound up to 7000rpm leave the diesel engines for big rigs and buses!
I'm glad the editing guys caught the Ricky Bobby reference and put it in, because I think the host didn't catch it.
If you want to talk sensible numbers on diesels, there's the BMW X5 m50d, a tiny 3 litre in-line 6 that delivers 380 hp, 550 lb-ft and about 37mpg (is very well build, looks good, etc.).

He blew out a freeze plug. That's hardly what I would call a breakdown.
I wonder how black the ceiling is in that Dyno room?
It depends on what you are comparing.
Reliability? Internal strength? Torque? US diesel is ahead.
Fuel economy? Power per liter? Materials innovation? Germany ahead.
It really comes down to what you want to compare.
'holly smoke' gets a new dimension here :D
the sound of that 7.3 makes me miss the old diesels, Can MT release a video of just the 10 trucks doing pulls with no words, just one truck after the other. Then repeat
" I left the nitrous on... Merrica!! " LOL
GUYS! Black smoke=wasted power. If your diesel makes 800hp and spews black smoke than it'll make 850-900hp without black smoke.
Since they're not ventilating the dyne room I'm surprised they're not standing above the stack with their fist in the air during pulls. Great challenge though!
The high altitude reduces the amount of oxygen in the air. They could run a lot more NOS to compensate but most of them probably wanted to drive their trucks off the dyno.
Oh man, that Dodge has some competition!
I know! I keep checking Motor Trend's channel waiting for the new one.
Oh Ricky Bobby, makes me laugh every time and the host didn't get it at all lol

However, credit where credit's due. Our "big fat lazy" engines are lighter. GM's 7.0L weighs close to the same as BMW's straight six.
thats why most companies put a cummins motor in pretty much every piece of heavy machinery like semis trains and construction equipment
See, its things like that that i have not been informed about. That also makes since why the new diesels are clean.
So what's the point of doing this if it destroys your engine in 10 seconds?
No, it's full of stuff like sulfates, silicates, and other stuff proven to cause cancer and serious lung issues. Plus the fine particulate matter is a major contributor to various lung issues.

Lohnes commentating.....diggin it
that's cool ha. I was at bandimere speedway yesterday at truck fest!
gotta make the shop smell like diesel at any opportunity they can!
unimogs are insanely good for terrain. and they can pull. its just a consumer point. me being a U.S. faithful, would buy and use the ram, f-250, 2500 HD etc. cause im loyal to the big 3.
are these guys not advanced enough to ventilate the exhaust fumes??
Why would you Host a Diesel Dyno day with a dyno room without ventilation??
lmfao at 19:48 making a ricky bobby move hahahahaaaaaaa
