A DIESEL Semi Faster Than A Lamborghini! 

Such a cool event! What car would you take out to the Salt Flats??

Wtf, so you didn't even show the truck running on the salt!?!?! What a let down

WTF? The Title, I was expecting to see a Semi Truck go over 200 MPH? Just saw a 42 min of talking?

Just WOW! That lope stirs the soul! Curious as to what @GaleBanks thinks of this beauty?

A semi with huge hp that can beat a Lamborghini and u don’t show it man that ain’t right lol

In actuality the modern Detroit Diesel big boy for the road is the DD16 4-stroke. The engines you mentioned have not been manufactured for over 30 years. Also, they were 2-strokes.

You guys are killing it with these long videos. Great to see you having fun.

42 minutes wasted hoping to see a truck go fast.

The bicycle bit was the best part of the video that dudes got huge set of balls if he’s going to attempt 200 mph on his pedal bike...

Just got to tell you Steve, loved this film. Just keep doing them. It's top entertainment.

that is awesome! but as an Aussie you need to check out the bandag bullet , all of those cylinders plus twin blown with quad turbo over with nitrous and LPG on top of that, big scary monster!

Thought I was going to see a truck hauling ass, what a waste of time.

What happens with that nascar car is the body's design is thoght to create side force, the left front fender creates vacuum and the right rear fender creates push, no matter you change de set up, airflow always will steer it left.

Steve, I really enjoy your shows here on YT, more so, than your TV shows. The reason for that or one of the many is you're not held back so much by the censors online. I mentioned before on one of your other episodes online that I lived in Vegas for 35 years. I wish we could have crossed paths we might have been able to make some money together. I've been a mechanic all my life and a pretty good one too, or so I'm told, lol. I got into the emission testing and repair program while I was out there. I got off on a tangent about myself when I just wanted to say how much I enjoy your online shows best. Thanks for sharing, my friend.

228 mph I didn't see it, so I wasted my time to make someone famous

He stands so close while talking to him. Give some space, you're getting in the kissing zone right there.

Being Canadian, the salt on this car hurts me inside

The current bicycle record is 184 mph, so I really want to see it happen. I really wish him the best of luck, It’s going to be spectacular if he pulls it off?

R.I.P. Jessi Combs...

NASCAR driver Bobby Issac was setting records at Bonneville back in the early 70's with a ex NASCAR winged Dodge Daytona. He still holds records there and he's been dead like 40 years.

Love the sound of that motor !!! 😍👍

Wow dude on the bicycle is crazy. But it’s cool lol

It is beautiful . In its totality it is truly a work of art . .. A work of art in action ..... Excellent Action ! Just Beautiful.

The dude with the bicycle needs to think about being more than road kill.lol

Another great video from welderup I really wanted to see the diesel truck with 16 cylinders go down the track that would have been awesome have a great day guys

28:00 200mph on a bicycle. Imagine accidently getting out of the draft at that speed. Might want to pack an extra pair of shorts😲

Getterdone Steve 👍😉

I only watched your "TV" Show a few times (hate tv too many commercials)..since found you on the tube..I am Subbed, and never miss any!!..It's GREAT!! Please don't ever stop these video's...

Best one yet Steve... could listen to those old guys all day.. lets build sumthin' big & go fast..

So, where is the semi going faster than an Lambo?

Don't stand so close to me. Respect peoples personal zone. Thanks. Can't wait to see the run!

Anyone else think Steve stands too close for comfort?

Well done Steve , really enjoy the videos on your channel. Keep them coming. Better than your TV show, all cars no bullshit...

I saw that video Lucas,. Hauling tail on 95. Damn 48.. YOU ARE A MONSTER..AM ALSO FROM MIAMI.. #DADE COUNTY BABY.. 👍🏾💪🏿

Wow man.! Steve, That's the sexiest sounding diesel, I think I've ever heard

Glad I jumped to the comments before getting too far into the video

That’s the best sounding idle I’ve ever herd

Great video Steve. Be pretty cool if WelderUp built a old-school 1910 Indian board track race bike for the salt flats.

Zat is zee bad ass engine, ja wohl! Sorry, couldn't help myself..🤭 But whole powertrain is just awesome! Did i understand right that diff was also from mining truck. And they just leave planetary hubs away so it give them such a long ratio..?

We had a v 12 continental engine twin turbo it was amazing couldn't imagine a v16 😎👌🇺🇸

I thought the idea of Big Red was to have somewhere secure to carry Blasphemi or whatever. Things go missing off ramp trucks like the Mazdarati

Cool video! I love going to your shop and seeing your cars run around town.

awesome stuff

Only thing missing is RS-25 engine on each side ... Great truck, Great guys :) (again, camera man !!! change aperture so the focus going wonky is not distracting as much !!!!)

@19 mins Mr. Parnell says, " That's an angry fucker, ain't it?"

One of the coolest things about hanging out with some cool as knowledgeable brothers and sisters is it gives you great ideas and you're dangerous you have some of the best and coolest builds in the world man and have hung out with some of the all-time greatest nothing but love bro that's for sure👍👍👍👊👊👊

MUCH RESPECT TO ALL THE PEOPLE THAT RACE THE SALT FLATS

Now, put a dry van on it, with 46,500 lbs of material, do that across Arizona, at or over 150 mph, and your getting into the ball park

Hey Steve, maybe u should clear- wrap the bare metal body? If u do it right, it's invisible! Protect that beast bro..

my papa worked for Detroit diesel for 40+ years miami @ pitts engine and transmission he was Allison builder

What happened to the roots blowers on the Freightliner? When I saw them blow up the motor in 2013 It had two roots blowers on top?

FLATout baby! Thank you . 154K bobtail, guage may have been working, those auction orphans .. sigh.

Steve.... What happened to the 16V92 Detroit that they use to run in it? Speaking of 2 strokes... what was the vehicle I kept hearing in the background with the 6V92T Detroit...especially while he was explaining the rear end setup around the 21:00+ point??

Now thats cool. Steves got a good eye for expensive shit I wish I could afford to do. Them are some great guys on that team also.

Big ass engine can take all that air and not have some much restriction

I used to cut pinions and crown wheels on Gleason spiral gear cutter 1930-1940s machinery.

about the semi truck that isnt alowed the belly an , are you alowed to rotate the crossbeams 45 degrees would make the frontal area and rear a point , might hep

Hell yeah badass time fun time at Salt counts man I knew I had good buddies out there somewhere to find you

That's looks like a great time 🏁✌🏿✊🏽🏴‍☠️

Eu. Gilberto. Brasileiro. Adoro. Seus. Vidios os. Vidios. De fabricação. São. Em. Português. Porque. Está. Nova. Versão. Também. Possa. Ser. Em. Portugues

Just found the channel and good stuff fella

FRIGGIN' AWESOME!!!

That truck has the lope of my dreams. Holy cow. 🤯

Have you considered getting a clear wrap on the charger. And yeah it would have been cool to see the semi running but regardless the video is awsome

What's the go with the chain drive on the screws? Can they handle rpm as well as belts? Know it's more a show rig so no biggie if there's some performance loss....

I don't know how you keep topping your builds that is sick 👍👻🏁🏁🏁 and inspiring!!! I live at the Beach everything rust out. All my poor old trucks.

0:45 that is fucking awesome!!! Mad~Max all the way!

Was it just me or was dude standing really close to the cowboy during the interview lol. You gotta give some personal space. Nice car btw

I love that my passion is biking and the cyclist in this video has the same birthday as me

you should pick up an old reo & toss that driveline behind the cab. A 180mph+ rat reo with all your touches would be insane

What happened to the footage of the truck running for the record?

A Semi is a Trailer.

Steve why wouldn’t you clearcoat it?

Way to SAVE THE SALT steven!!!!!

Man, that engine would be awesome in a crew boat!!!

I'd like to build a 91-92 firebird for the flats!! Put a couple gear vendors, overdrives in there! With atleast a 2.23 gear, and 29"+ tires, with a Honda v6. Ha-ha!!

They have air intake behind cab where vacuum is. Why not intake up top help force air in?

That engine is a 2000 series Detriot/MTU, the 16 cylinder version can be rated at 2600hp from Detriot/MTU. Guy claims to be a big diesel head, yet doesn't know that the 2 stroke Detriots were off the road 30 years ago... Holy fuck it gets worse, a diesel cannot lean out! It's literally a lean burn engine, it throttles power by means of controlling fuel to the engine.

I found a Woody if your looking for one still, no chassis,just the body. I will try to figure out how to send you pictures.ok I sent pictures to you, not sure if it worked.

That UDT (Unlimited Diesel Truck)record is insane @272mph but its a wonderful dream

Anybody else think the guy on the right sounds like Sam Elliott !??

The salt flat. It’s a great time!

Yep, shout out!

Is that Sam Elliott? Talking about the rig.

What was the engine designed for

Very educational I never seen a desial piston it's huge. I could carve something cool out of it with my grinder.

I worked on those mtus engines in Texas oil fields awesome to work on

The semi gets its name from the trailer it pulls. Since this vehicle does not pull a trailer, it's not a semi.

Fantastic video!!

I saw you out there! Got some pics of it in town and out on the salt.

HOW ABOUT USEING THE ENGINE AND DRIVE TRAIN FROM A UNION PACIFIC LOCOMOTIVE . ON A LIGHT FRAME.

Dude!!! Where did you find Hunter S. Thompson?!?!

Chain drive on dual detroit blowers looks pretty damn mean.

SO where is the video of the truck speeding?

Mr. welderup, Read the comments! Learn .........

Yeah always wanted to have grown up in the USA

should of used a ceramic detailer since it would last the event with one application

He isn't going to clean it lol

WARNING: NO speeding truck in this looong video.

Was wondering when I was going to see the truck hit 200+ mph. 35 minutes in, I decide to scroll down to the comments after listening to bycicle man, come to find out from others that there is no such content. Re-title this video.
