This was filmed at Bandimere Speedway in Morrison Colorado.
Elevation is just under 6000 feet above sea level.
Check out Bandimere.com for more info on the track
I make drag racing videos and put them up for everyone to enjoy.

Ran faster and cleaner. Proves DEF is horseshit

[@justinmartin8887]

Wtf haha like this 6.7 ever did have def in the first place

[@JuanGonzalez-mh3pe]

You do know that 6.7 don’t got DEF right?

[@johnlonghorn5856]

Ur slow huh

[@garethjohnson4749]

When the 12 valve runs cleaner than a Common Rail...what is this blasphemy!?

[@5.43v]

NOX

[@evanolson8819]

One is calibrated properly, the other is calibrated by a sister-cousin loving redneck.

[@chetgoodenough8749]

Wait till you see the news in 2024 about the new one

[@gallegosconstruction9592]

5.9 all the way!

[@MPjustaman]

Like watching a pair of grandmas trying to beat the traffic signal. 😂😂😂

[@mkultra7911]

that was AMAZING

[@Tedkelvin]

the difference between a single turbo 6.7 and compound twins 5.9.

[@odenvalhalla4724]

👍 5.9

[@natedog01able]

The 5.9 has a shorter stroke soo it revs quick on top

[@RohanSanjith]

5.9 is a long stroke engine 102×120

[@texaslibertyadvocatenetwork]

@@RohanSanjith It has more high end torque as opposed to low end... 6.7 has better low end torque than 5.9 but power band for 5.9 higher

[@theonedubgaming5895]

​@RohanSanjith I think he means compared the the 6.7s stroke

[@charliebarton827]

That's not even a 12 valve look at the mirrors its a24 valve

[@franklinZac]

mirrors mean nothing they made 12 valve 1998 with those mirrors

[@gumps1986]

Because no one EVER puts moose mirrors on second gens...
It is a quad cab, so if it’s a 12v it’s a 98.

I have both trucks. The 2nd Gen has way more parts but the 3rd Gen is a little faster.

[@eboi8209]

Second gen left later and braked earlier still won nice

[@kalebstout7673]

Man I want to know what has been done on the 12v

[@datsun7023]

Probably anything and everything 😂

[@tony4metallicaify]

Ole 12v tuned right!!

[@robertcotrelljr8573]

12v! Lol

[@BiggHoss]

As Gale Banks says, *Paraphrase* If you're rolling coal shit aint right

[@MakeAnything-]

Thats actually not true. "coal" as its commonly referred to is heat. Getting the turbos to light the fastest requires heat. It should smooth out as the heat and cyl pressure rises.

[@BiggHoss]

@@MakeAnything- I really hope no one has ever let you tune their truck. "coal" black smoke, whatever, is unburnt fuel. If you see black smoke it means your air to fuel ratio is fucked, much like your little statement there. Bumping up the fuel causing black smoke will raise your EGTs, which damage your engine. High EGTs will damage your cylinder head, overheat your pistons scoring and warping them. It will overheat your turbo, not only that, it will reduce your engine power.
"Under sustained excessive EGT, the square corners at the outer ends of the vanes, where the material is thinnest on the turbine wheel, can become incandescent and then melt, resulting in a rounding off of the square corners."
"In extreme cases, high EGT can drive the turbocharger into an overspeed condition that exceeds the designed operating speed due to the additional heat energy. When this happens, either the turbine wheel or the compressor wheel may burst. If the turbo doesn’t go first, excessive EGT, if sustained, will damage the pistons. Such damage can include piston deformation, melting, burning, holes, cracking, etc. This damage is cumulative, so if you slightly burn a piston top, the engine may continue to run without problems, but the next time you run excessive EGT more damage may be done, and so on, until failure occurs."
You know nothing about turbos. I have no idea what you think "light" means but turbos work on boost pressure, a hotter turbocharger can generate more boost pressure, but that doesn't mean more power. The air density and temperature play a crucial role in determining the actual power output. Cooler air will compress with less effort than hotter, thinner air. Hotter air means less density, which means less oxygen going into the engine. This can result in less power, even with increased boost pressure.
Just please stay away from Diesel motors.

[@MakeAnything-]

@@BiggHoss "Burping" lol you know nothing about tuning. I have tuned many pros. All you have to do is go to a tractor pull and see exactly what I am saying. You arent worth the response

[@BiggHoss]

@@MakeAnything- You tune for the jackoff that that blows his motor every year racing, I do go to tractor pulls, almost every time someone's motor blows, those must be the pros you were talking about. I tune my motor that will last 400k+ miles driving on the road doing what a truck was meant to do. I will give you credit. You are in the repeat customer business.

6.7 more aerodynamic with its useless light rails

[@zachariahjones7885]

the 5.9 clapped the 6.7 :O

[@texaslibertyadvocatenetwork]

My stage 3 5.9 was much faster...

What did you have done to it? I’m currently building at 9712 valve Cummins compound turbos whole 9 yards.

no one cares.
