As the NHRDA has grown, so has the diversity of activities they include in the event. In the past 18 months, Big Rigs have been incorporated into the theme, and so with sled pulls being hosted during the event, the inclusing of Big Rig Sled Pulls rapidly became a highly engaging competition. Truckers from all over converged upon the Texas Motorplex in Ennis Texas for the event and the opportunity to walk away with prize money in the drag racing comp along with the sled pull comp as well. Results varied wildly, from carnage to full track pulls to literally pulling the front ends completely off the ground.

I love hearing the exhaust sounds of these big rigs.
same m8
These are mostly cummins n14 600 celect engines
The old white kenworth had a two banger Detroit
I agree with you on that one
That old white single stack kenworth suprised me. sounds wicked too.
Rexious 0 DETROIT!!!!
BIG RIG... They are Works of art!
Am I the only one amazed by a sxs pulling a semi
this is why i love american trucks
I really enjoyed this
Absolutely beautiful!
that first one was towing the mail and some
At 4:00. Love the turbo whistle on that KW
Hell forget the turbo, see it lift the steers as it bogs down.
I like ya'lls videos and they all did great.
Thanks bud! Glad ya enjoyed it. Appreciate you watching 😊😊
Dude! That mule! (John deer) holy shit! Power is (kinda) real!
Raptor 318..... what "mule (John deer)" are you referring to?
So no ones brought a tank to one of these yet?
Hahaha....that's pretty clever. I'll have to put the word out and see if we can make this happen...
+rekjavicxxx That would be insane for pulling and for tug vs trucks too
Yes!
The tanks are always fun. Hard to stop that kinda traction and mass.
I saw one where they brought a HEMTT. The truck weighed more than the trailer.
nice videos man
what would the 0-60 times be of these things if they weren't towing?
that white truck was trying hard . good effort
initialB 240 where's your effort where's your truck gtfoh
initialB 240 That one was my favorite here by far too. The Sound of its 2 stroke Detroit was awesome!!
initialB 240 ~
Pretty sick trucks with dad would have kept his and made it a show/pull truck
Never in my life would I do this with my truck lol. I enjoy watching it though. Very few could actually shift here though. It’s not that hard if you float em instead of double clutching.
After watching the Rodeo Du Camion videos, these guys seem to be leaving a lot of time between shifts
Nice
The white kw has a Detroit 8v92t
Those big ol' stretched out wheelbases aren't doing them any favors.
thecohorts.... not necessarily hurting them, either.
The first couple runs, you can see the driveshafts torque up like an archer's bow.
Are these pro stock or stock
How much does that thing weigh to be able to stop a truck like that?
jake brake and brakes
ohhh I didn't realize the brakes were on
what why would the jake brake and brakes be on
the actual issue is that those trucks really don't have much traction since they don't have weight over the rear tires so the trucks just spin
+Jake O'Quinn.... Jake, don't listen to these "armchair experts".... they're either "pulling your leg" (joking or just plain.. lying to you), or.. they really do NOT have a "clue" about what their talking about.
What causes the truck (tractor, or whatever is pulling the sled, depending on the class) to be "pulled down" to a stop.... is just pure weight and Friction (against the dirt).
How much weight is in the box... depends on what "class" the pulling vehicle is competing in. In the case of the NON - "Pro"... "Street Semi" class.... as these guys are pulling in, in this video... the box "should have" 60 to 65,000 lbs in the weight box... however, judging by the distance some of these "Non - Pro" trucks are pulling the sled to... I would definitely say that the weight is definitely a lot LESS than the "legal" points weight, that would be used at a pro event.... perhaps in the area of 25 to 30,000 lbs.
When the sled is at approximately the 150 ft mark, the sleds "pan" (long - flat, plate that is under the sleds frame) will lower down (by hydraulic ram), partially putting pressure directly on the dirt, and removing "some" of the weight Off of the rear axles at the rear of the sled.
As the weight box continues to move forward... more and more "down pressure" is put on the nose of the sled, thereby pushing the "nose" further into the ground, while at the same time... exerting more and more downward force on the rear of the semi (or whatever is pulling the sled).
As soon as the weight box is "all in" (reaches the forward most point of the box's forward travel)... it trips a 2nd switch, which instantly engages a hydraulic pump which lifts the rear section of the sleds frame (pushing Upwards from the rear of the sleds plate on the ground, with a hydraulic "arm"), and therefore... its rear wheels completely off the ground, effectively putting full downward pressure of not only the weight box, but the entire weight of the sled, onto the plate, that the truck is trying to pull.... and the further it goes, the more the sled is trying to plow itself into the "track" at the nose of the sled..... until the combination of weight and friction, overcomes the power level of the pulling vehicle at the wheels, and it "spins out"... or just "loads" the rear axle(s) sufficiently enough to lug the engine down, to the point of nearly stalling it.
The sled operator has full control of the speed of the weight box, trip switch positions, starting position of the weight box, as well as the ability to shut down the engine of the pulling vehicle, -via- an emergency "pull switch" in the event of an "out of control" pulling vehicle, or other emergency.... such as the pulling vehicle (regardless of type or class), breaking free from the sled, during the pull.
The emergency "kill switch" is the very first thing that is hooked up when the pulling vehicle is backed up to the sled..... and ALL PRO pulling vehicles are required to have the system employed on their rigs.
I hope this helps explain how all this works.... regardless of whether it's at the local county fair.... or, one of the many professional sanctioning bodies - points meets.
Who much are your jumpers hats and t shirts
truck rolls
Why not make Em 6x6 for this job ?
Do they ever do pulls on pavment!???
+Baker3939.... No sir, they do not.
Did the white truck have a detroit diesel?
MrHeavychevy86...... Yes, an 8V92T.
best shifter wins
frames were harmed in the making of this video
✌
Seems like some get to shifty and bog out
how does this work?
What is the name of the First truck?
Anyone know what kind of engine is on the truck at 3:40?
codejunki567 Detroit
It will be fun to watch the Tesla Semi Truck make all these look like Tonka toys
what's making the truck slow down?
john magee Progressive weight transfer to the front of the sled
what model kenworth is that at 3:58 t400?
+john dowe.... it's a Pre - 1983 "A" model.... standard hood (length), and powered by an 8V92TA Detroit (736ci - 4.84" bore X 5" total stroke length including 1" for port opening, plus exhaust valve opening = less than 4" of actual power stroke length)... which at minimum output (factory ratings), was rated at 350hp NA and 1,250 ft lbs of torque.. with a "maximum" output (for industrial and automotive [re: semis]) of 550hp (with twin T-04 turbochargers) and 1,680+ ft lbs of torque.
Marine versions were rated higher... along with higher rpm limits, although still well below potential. Have seen several 8V92's with outputs of over 2,000 hp. on the dyno. The "little" 6V53 series (318 ci) are capable of over 1,000 hp.
holy tit balls thanks for the info
john dowe..... Your very welcome.
4:14 that was a old truck
.....I wonder if anyone has ever brought a Volvo out there?
JohnnyNismo..... Volvo's have been entered before... not necessarily at This particular "pull"... but yes, Volvo's have been represented.... no different than any other brand, as they basically all use the same componentry... unless the Volvo happens to be Volvo powered.... in which case, they do Not do well against the longer stroked US engines (Cat, Cummins, and even the smaller bore Macks).
The European engines are all "over square" designed, and cannot "hold", or sustain the torque, as compared to "under - square" designed US truck engines, where the Stroke is longer than the diameter of the bore... which has higher inertia due to a combination of heavier mass and higher "piston velocity" (speed) at any given rpm, compared to any "Over-square" designed engine, even if they produce identical horsepower and torque values.
This is the reason why the older 2 cycle Detroits never "seemed" to pull well, against the 4 cycle engines of Cat, Cummins, Mack, Allis Chalmers, etc..... because of the Very short "Usable" (Not the total) stroke length, of Less than four (4) inches, even though they actually produce approximately 30 - 33% More power per ci, than the 4 cycle engines.
Before the manufacturers began applying turbochargers to the 4 cycle truck engines (late 1960's... 1975 for the 2 cycle 8V71T Detroit), and both the 4 and 2 cycle truck engines were all NA (Naturally Aspirated).... the "little" (ci) 2 cycle GM Diesels (as they were branded until 1965, then were re-branded as Detroit Diesel) would "walk all over" the big ci 4 cycle powered trucks in the grades (mountains, etc.).... the 4 cycle diesels without turbocharging are pretty "weak" compared to the 2 cycle design, in terms of power output on a "per ci" basis.... whether NA or "boosted" (turbocharged).
Most ALL diesel engines with power levels in excess of 50,000 HP (primarily in Marine Applications)... and ALL diesels above 65,000 hp... Are of 2 cycle design.
If these trucks can tow 40,000 to 80,000 pounds! Why do they struggle?
its because of the weight placement and how the sled moves it over the axles the farther down the track it goes, in a different setting with hard ground etc most of these trucks could pull 600+ tonnes, the new Volvo FH750 has done a demo pulling 750 tonnes of trailers at a dock yard for an exibition it's on youtube somewhere mate you should be able to find it
The green flag drops, let the carnage begin!
This guy has the EXACT voice of the announcer in Rock N' Roll Racing!
c15 3406 or n14 lol
first one had to be expensive
It was an axle shaft. He had it replaced overnight and raced the 1/4mi the next day!
+rekjavicxxx well damn he wasn't messing around
+Derek Adams It's not hard or time consuming to replace the axle shaft on those axles; much easier than a 12 bolt, 9", or Dana. It often takes longer to drive to Peterbilt and back to get that part than it does to replace it. 10 nuts and a gasket if I recall correctly and its out (wheels don't even come off). The bearings are in the hub.
StL ChuckO..... the axle design you're describing is known as "Full Floating" axles... and yes, Very easy to change out.... however, I think the Pete was a little "deeper" than just an axle.
Cat vs cummins. This is all this says to me lol. I like them both I think the brand locals are tards they both go millions of miles.
Loyal
You forgot detroit. The guy who broke down has a detroit in it
rogerm...... not sure how you came to That conclusion (that it has "a detroit in it").... but, no.. it does not... it's a Cummins. The Kenworth day cab, however.... does have an 8V92 (2 cycle) Detroit in it.
Google rick fenwick peterbilt thats his truck. Hes got a "Detroit series 60' not no cummins
put some damn weight over the rear wheels
sec
Very timely response sir! Thanks for checking it out
First
Nice response time guys! Appreciate ya watching
TRUMP 2016
Fuck you & him
+Chris Love what r u 12. I know you r but what am I... shut the fuck up u probably ain't even old enough to vote
+Judd M Lmfao I'm way older enough to vote I look young cause I take care of myself
+Chris Love OK.. Good 1 ain't it past your bed time
+Judd M Lol those wack ass jokes man. I'm grown I don't have a bed time clown
