Competitor Introductions, Dyno Testing and Fuel Consumption - Diesel Power Challenge 2016

[@moaski]

You guys should have brought back Lavon Miller! "Re-setting the field," means not including the best trucks for this competition.

[@MrAuz4]

FINALLY...thought there was no DP Challenge this year, these are my favorite vids from Motor Trend!

[@d1sknt73]

didn't even use the silly gas and smashed it. what a beast that Cummins is. very smart setup

[@yung_richtah]

yeah man, true turbo diesel power without nitrous for the win

[@FM4AMGV]

i think it has to do with destroking it. able to get more rpm out of the same piston velocity.

[@hivetyrant7]

I like to think I'm one of Motor Trend's biggest fans, the production value of your videos is always top notch. But this video is all over the place. What is up with the audio changes? That said, freaking love these machines. Can't wait to see the rest!

[@jeepsterdaddy37]

they had to do extra voice overs to fill gaps that were missed.

[@weed46]

The good producers don't want to work in this mess of rolling coal crap

[@wobblysauce]

More info/air time on the Dyno fuel run would of been good.

[@jamesflores9456]

when they shot to the clip of destroked cummins after dynoing the blue ford

[@yucannthahvitt]

Why the hell aren't you guys venting the exhaust?

[@J8ck_hoff]

not sure if you can tell but most of these people are already brain dead so a little soot shouldn't hurt them to much lmao.

[@roguedogx]

they might be, but if they are the fan speed is just not fast enough. 1000 hp does tend to consume a lot of air.

[@doublevanoz]

almost shit myself when i read this

[@SchrottiJr]

I bet they are, but just not enough. And also those trucks have their exhaust all over the place so how you wanna do that?

[@yucannthahvitt]

Da vid Same way you do it in any dyno cell, you dumb shit, a long flexible metal hose. We do it all the time at the dyno here, it isn't rocket science.

[@olov244]

love this challenge, can't believe it's been a year since the last one

[@mathman1923]

the whole dyno cell is an egr setup for man and machine!!!

[@omfgwtfbbq90]

actually made me laugh lol

[@mathman1923]

happy to brighten your day :)

[@GhostRyderFPV]

Thank you KJ, Brian, and Diesel Power crew. These are always fun to watch and read about, and I'm really glad you keep it fresh with new competitors each year. Diesels have never been my thing personally, but the numbers they generate are staggering! Looking forward to the rest of the competition! Edit: Good luck everyone!

[@samc5898]

That dyno room is the most idiotic thing I've ever seen. No exhaust extractors or anything. Set aside how bad it is to breath that shit in, but think about your engine. That cooling fan sucks it right up and shoots it right at your intake. For the people running filterless turbos, thats a REALLY dumb thing to do

[@arsh9551]

i was thinking the same

[@maxracingteam23]

Sam C at least get that fuckin exhaust out of there. Wtf!

[@alexk.8715]

Like external EGR haha

[@ZepG]

Hmmmm..... dumb people with dumb trucks in a dumb dyno room, I think I see a pattern here.

[@wademckenney6858]

+ZepG massive power big trucks more manly than what u drive

[@tinderinc]

Ton's of respect to everyone who brought there truck. A special thanks to the show for sharing the country information and not just the province / state.

[@jeff-fm7rh]

I've been waiting for this all year

[@texasflysuperstar]

Been waiting all year for this!

[@NomadPoker1]

I can't figure out for the life of me why they would dyno diesels in a place without proper ventilation. That's just silly.

[@tinderinc]

Its called being an American.

[@AgentSmith911]

lung cancer... it's the american way.

[@A_Man_Of_Culture_]

Fun Fact: A diesel engine that has optimized cylinder scavenging, and purging will not produce any black smoke, and will reach up to 45% efficiency! Sadly instead of making their engines run as efficiently, and as smooth as possible they just add boost, and fuel in hopes of power.

[@A_Man_Of_Culture_]

sdfghjk

[@Iceheart721]

When your talking performance, especially performance at the peak of an engines capacity you will always have access fuel. Doesn't matter if it's diesel or gas. Prime example look at the top fuel drag cars. Fastest accelerating vehicles on the planet. Just look at the pipes at night time and you can see the nitro leaving the exhaust. There's so much extra fuel it doesn't even have a chance to combust it all in the cylinders and they shoot flames almost 10ft out of the side of each car. In the right conditions you can see liquid trickling out of the exhaust. Yes throwing air and fuel at a engine is how you make power. Thats how everyone does it. How much air and fuel can you get it, how can you do it quickly and how fast can you get it back out are the core premise of horsepower. Could they make them more efficient? Yes. But this is a dyno event the trucks are tuned for performance only anyway.

[@1tylerproud]

mrsuperbuckets it's not in hopes of power. They make power. Lots of power. Boost and fuel are a staple of increasing power.

[@MCMonsterbuilder]

Yeah but the thing is it makes more power, not that healthy for the Engine or turbos I suppose but it makes power and it's probaby too difficult for most people to tune it to gradually increase fuel with boost so that it makes power without smoke. I mean most of them clear up when boost is fully there but yeah nothing to defend here. If I had a Diesel I'd try to keep the smoke on a minimum level but then I wouldn't want to go for maximum power and torque, I'd keep it usable.

[@thestig572420]

Who cares ?? BOOOOOOSSSTT

[@arbiter1]

@13:00 isn't that cheating having someone open bottle of nos in to turbo. If it isn't part of the truck then that is cheating.

[@EvanDavisTheOne]

Last year one of the contestants was called out for that and his run was deleted. So this year they must have changed the rules. But I agree with you 100%

[@arbiter1]

Well in the towing coarse no they wouldn't but in the drag race they would use it.

[@ninja2kernow]

Forgot i watched this last year.Great to see it in my inbox,Great show.

[@kevinthomas895]

Why does this dyno cell not have a proper exhaust hose system? This isn't safe. Find another venue for dyno testing.

[@FoxCammer]

1500+hp 2000+lb ft tq would melt or blow the hose right off the stack(s) How do you propose they "fix" it?

[@kevinthomas895]

[@douglasdtlltd]

Sorry, BUT WHERE IS THE consistency FOR THE AUDIO CLIPS IN THE BEGINNING.

[@kingpohhere2678]

sounded like that girls duramax was bouta nuke lmao

[@nerovice121]

That dyno needs more ventilation

[@jrnascimento1448]

That was cool. I really enjoyed it. I'm anxious for the next one.

[@Oliver0200]

why would they put a dyno indoors is that even legal I mean you saw all the exhaust circulating in the room

[@mattcat234]

Because America!

[@axshunjaxon4561]

I rarely see outdoor Dynos, other than shows

[@IntelligentHorseworldofrandom]

Finally something interesting! Hooray for Ray! those are some good engines, both Duramax and Cummins! really like this competition!

[@100thMkey]

Very well produced, I look forward to the rest of the challenges

[@xXBurntBaconXx]

ok that destroked cummins s sounds interesting. I wonder why he did that? I also wonder if we are ever going to see the 5.0L Cummins in the Nissan Titan XD in this competition in the near future. it may not have the displacement these trucks have but would still be interesting to see.

[@mibars]

They actually explain it in the video: Rod angles are smaller decreasing sideway forces on pistons, cylinders, etc.

[@rrpeters]

Destroking a motor reduces the rotational mass and allows the engine to spin higher with less load. As long as the fuel system and heads can handle the higher flow rates you will make more power and cause less stress on the bottom end, especially under boost.

[@BenLeBlanc1]

Why don't they pipe the smoke out of the dyno room? Would probably make tuning a lot easier as the air would be more consistent.

[@brodygoodrich926]

The awsome thing is that while this was filmed my brothers 900hp 6.7 was being worked on at ATS

[@nickfleischman4881]

Finally!! I've been waiting for this for so long.

[@DanielJaegerFilms]

14:02 um.... different truck? Wrong video clip perhaps? Otherwise fantastic video!

[@Sj1bby]

I must say I seriously like the content of this video. Lovely work of Brian and the editors! It's good to see the masks on the dyno guys! I just have one problem with the show. It should be called: Diesel torque challenge :)

[@Schuttsr1]

did they kick lavon out this year?

[@1tylerproud]

I love this competition. Crazy trucks pushed to their limits.

[@PHATDAN420x]

Wheres buddy that won the last two years!! Hes a beast with his dodge

[@PHATDAN420x]

Lol nvm got my answer

[@bigchungus1225]

@5:38 he explains a person that wins twice can't come back.

[@garfield1415]

i love this time of year! love the show!

[@chipsk8361]

What, no Broughammer?

[@nathanielmertes3010]

I've been waiting for this for ever!! Day 2 is tomorrow then?

[@cameronjenkins6748]

I was starting to wonder whether this would even be up on youtube. As a guy who doesn't have any affinity towards any of the engines in use here, I find it interesting that the Cummins engines tend to make enormous amounts of torque and they make their power at lower engine speeds. I just wish I could do this with an old 1950's GMC with a Detroit Diesel 2-stroke under the hood. That would bring some excitement to this competition.

[@wantu2much]

just wondering why they put the fuel challenge on the dyno vs out on the road. It seems like they dont want the trucks to drive on the street for the event. i think the best part of the challenge was to see them out on the street.

[@bestmillimeter1858]

I read the printed version of this. It said they didn't want non EPA compliant trucks to drive on the street.

[@wobblysauce]

So.. in other words.. not street legal...

[@Rubmaster]

YES! Diesel power challenge

[@DanielPerryRally]

Feels like the power levels have come down from last year?: Hell some of the guys I work with are making the same number on mostly stock Cummins with tunes?

[@NBSV1]

Daniel Perry On a dyno like this it's very hard to get the turbos to spool. The engines make lots of torque but have a short rpm range so it runs out of rpm before the turbos can really spool. So, most of them could likely make quite a bit more power if they had a way to better load the truck down so turbos could spool.

[@DanielPerryRally]

Makes perfect sense, feels as though they could make heavier rollers for the dyno and then calibrate the system to compensate for that?

[@keon5779]

I know right? before some cars were pushing 2400 hp!

[@KevinSmith-qi5yn]

One of the guys is running a stock Cummins with a large turbo and tunes. But it's a Cummins, it will make the power as we have seen in years passed.

[@dilsher12]

wow didnt know tune only could make 1000hp and 1800 lb ft . The altitude also makes a huge difference , the turbos take forever to spool up

[@johnstorer159]

14:04, that's not an F-250 lol. Enjoying the timely coverage guys I can forgive a little mis-edit!

[@alandominguez1707]

Wasn't that guy KJ Jones on another magazine... he was the one with an emerald green foxbody 5.0

[@saberhowell95]

Would sucking all that soot back into the intake not decrease peak power? By the time they were at peak RPM a lot of them were sucking soot back in through the fans because so much had built up

[@kfjfjfjewlsls]

KJ, do you think any of these trucks will wheelie?

[@JustinKelly]

Editing mistake @ 14:01

[@liamcardoza9268]

why didnt they show Travis Kollers dyno run? or was i just not paying enough attention?

[@Boomer8404]

You know, this is at least the second year that I can remember Diesel Power Challenge using the same dyno shop. I'm surprised they haven't taken the time to setup a proper exhaust ventilation system.

well it didnt say so, so no?????

[@irishsavage8715]

When did Darius Rucker start hosting DPC?

[@BimmerDrives]

What's the long term impact (if any) of excess smoke on Turbos? Or any other engine components?

[@jessekulbe1855]

When the smoke clears up it'll typically clear any soot out of the turbos so as long as it's not lugging down constantly its gonna be mostly fine for the turbos. Excess fueling can burn out pistons though

[@the_lancaster_libertarian]

3 of the 5 videos on their playlist are private. wtf

[@mohammedalbanna7889]

why there is no ventilation in the dyno area???

[@jorgenunez4328]

when is the next dyno I want to go

[@Micah_Makes]

For the dyno, why on earth aren't the evacuating the soot? That much soot will be having some influence on the top end numbers!!

Diesel overfueling challenge 2016

[@nitramdh]

Kelsie Epp's truck looked pretty solid to me. The other guys looked like they were hacking their trucks at the middle of the competyence

[@croskey111]

where are the trailer hitches on these trucks

[@redlinesteez9630]

can you do a year with cars? iv seen some crazy ones.

[@lelandeggleston1041]

How much loss happens when the trucks suck back in the exhaust?

[@Freemananana]

Holy Hell Sally. Who dropped y'all when you were born? Chrome rims with low profile tires, destroked motors, racing seats without a cage, and the list goes on. This is terrible.

[@brockwalls1413]

Freemananana Dunno what trucks you saw, but most of them had at least a half cage.

[@Freemananana]

They are just dyno queens. The sled pull was off road.

[@Foxontherun2]

but they needed those ebay headlights and random green engine parts , how could they live without a green oil cap?

[@jlopez1017d]

Freemananana lol and diesel people make fun of ricers

[@pfcvdv]

Soo... What kind of mpg did they get?

[@lollol-ko8eu]

hey what is the name of those systems that nas car drivers and baja buggy drivers use to keep cool you know the system that helps them breath

[@curtmaddog3457]

does anyone know what the 2015 black powerstroke dynoed or why it didnt dyno??

[@marcuscoster6529]

How come every single performance diesel has all filtration removed from the exhaust? What is the point?

[@benclausen6805]

it's a restriction. kills power

[@1FiftyOverland]

because eff the EPA.

seth richards they did that last year too a Ford to a cummins

[@Lameboy7]

My favorite event every year right behind BDC

[@karlnapp7564]

Next year, try that without all the smoke. Thats the real challenge.

[@TR33ZY_CRTM]

Karl Napp That would be impossible for them. Diesel engines that don't give off any emissions don't make as much power as they are making now.

[@karlnapp7564]

Its possible. Grand Prix trucks stopped smoking years ago. I have a 12 year old Wendland Polo tdi that does not smoke either

[@TR33ZY_CRTM]

Karl Napp Like i said, not possible for *them*. They don't know how to make a powerful, but yet efficient diesel truck that don't smoke. All they do is just crank up the boost and add more fuel than air and hope for 1000+ HP.

[@wademckenney6858]

its a desiel truck with stright pipe and 1000+ft lbs Duh its going to smoke if u have a desiel that doesn't u got a problem

how do you enter Diesel power challenge

[@jamestupper5599]

14:02 ROFL I always enjoy the editing on these videos

[@adrianware]

why not put a exstracter tube on ?

[@bailey7067]

Does nobody drive manual trucks anymore?

[@diltzm]

It's not DPC without allowing Levon Miller the chance to defend his title. He beat everyone two times in a row and it's unfair to change the format like this.

[@MMXProductions]

Boring as hell without the champ. Why "reset the field"? Create some hype. Pretty disappointed they didn't bring him back

[@diltzm]

Yeah if they wanted trucks with intact emissions equipment just create a second class. Have an Open class where anything goes and a Street Mod class with emissions stuff. And they're not even driving over the continental divide this year either.

[@MMXProductions]

That would go a long ways to improve the competition. Motortrend is such a big platform for motorsports, and this years DPC just seems amateurish

[@nealuss]

An emissions class wouldn't really work with modern diesels. Anything with DPF or DEF, for example, has to have everything deleted to do any kind of worthwhile tune. Any other emissions equipment is really just B.S. anyway. Gone are the days of a simple tuner adding 100+ HP. A full turbo back exhaust is required for anything you can actually measure.

[@TedGNE]

Love the competition and love my diesel (04.5 Cummins) but I am a bit disappointed Miller wasn't able to return. He put up some serious numbers and one he!! Of a truck.

[@xjesse92x]

it seems like there is a lot more soot than last year's Diesel truck challenge but less horsepower and torque. So bad tunes for everyone i think is the issue because the soot is gas burning in the exhaust and not getting used up in the cylinders

[@milesgochuico6323]

why so much black smoke?

[@Cobb]

These guys are pretty much all super modified, would be interesting to see different classes light stock and modified.

[@Shredxcam22]

Only a few Cummins? Too many complaints in the past when the smoke the competition ?

[@andykurz]

Seems like it shouldn't be legal to have some guy standing in front of the truck spraying nitrous into the turbo. If it can't be done while the truck is moving, what's the point?

[@jamalmazahoe1379]

i have a feeling more than one of them were blowing almost as much smoke as their trucks while they were in colorado 😤😧
