Man! He's beating the hell out of that jake brake! ONLY A TRUE PROFESSIONAL TRUCK DRIVER CAN UPSHIFT THRU THE GEARS WITH THE JAKE BRAKE ON WITHOUT MISSING A GEAR!

this thing has the toughest sounding jake brake iv ever heard

N14 hands down my favorite jake.

Love the turbo spool down after each shift!

Gotta pop in just to listen every now and then sound never gets old. 👍

When your dunk and this is the kind of music vids you watch

Just come back to hear that Cummins talk shit! 💪🏾💪🏾💪🏾

saw this back in 2010.... to now 2021 and still to this day nobody else try this for fun or challenge this video? still the best i guess :D

That is the absolute best sound I've ever heard, can't wait till I get my own truck to open it up like this lol

After a long day of fixing trucks for a living, nothing puts a smile on my face like playing this at full volume with the woofer cranked up.

I used to drive a log truck before I started work with the railroad. I had a 1992 red Peterbilt with a 400 Cummins and 10 inch straights with no muffler and I used to make some racket, especially with 40 tons of pulpwood. That was a nice video. There was a switch where you could switch between 2, 4, & 6 cyl. jake brake.

Best video on KZfaq and probably the most beautiful sound in the world. I could listen to this all day.

Love that sound & love the jake brake

sounds like music to my ears

It sounds amazing, but something as out it makes me miss when my grandpa had no muffler on a ford f650 with a c7 cat. Took a trip to Chico Ca from Sacramento in that thing, came back going "WHAT?!?"

Sounds awesome! My family has one in a Freightliner wrecker and it screams with the jake turned on just like this. I have seen people next to us jump while sitting in the 4 wheelers.

I always keep coming back to this vid...the N-14 Signature 500/525 hp version is still my alltime favourite heavy truck engine, btw...(though 460+ are all good). Great sound!

love it! one of the few vids of a driver that knows he can have the jake switch on the whole time while driving! its a meaner sound too,thanks!

Lol music to my ears. my dad has a m11 370 Cummins i wish it would sound like that.

cool dream. my dad was a diesel mechanic for quite a while. he was thinking about opening his own shop but the money wasnt good enough. Now he has his own small company of 4 trucks in maryland hauling gas.

That engine & jake sounds freaking wicket thanks for the ride bro.

Sick . I drove a n14 bigcam . Love the sound.

you just dont understand how big that makes me smile. LOVE LOVE IT

one of the best vids here on youtube..love the sound of a cummins!

Man i love the sound when Jake braking reminds me when i use 2 go truking with my grandfather.

the best exhaust ive ever heard on a tractor! bad ass

A jake brake works on electric solonoids, an extra cam lobe and an extra valve in the cylinder with a collapsible stem. When the jake is on, the solonoids turn on a magnet, which make the valve stem extend out, allowing the camshaft to open the valve when the piston is at max compression (just before the fuel is injected)...allowing the compressed air/fuel to burn outside of the cylinder.... the turbo spools up, increasing intake pressure and providing more stopping power while using the jake.

Badass! I'm sure the neighbors loved it!

this i didn't know. i'm only 19, and i know that some of these guys are truck drivers and diesel mechanics, but diesel power is basically my life and i try to learn anything and everything i can about them. thanks for your info! i also frequently drive an international 8100 with an M11 Cummins, but this has no jake brake

Till I just read the last comment I didn't know what a jake brake was either, except it sounded awesome when used. Thanks for telling

wow that sounds great. Cummins and detroits have the 2 most noticeable motors out of any diesel ever produced

man thats a good sound. i love a loud jake brake

Gotta love that "pewwww" noise. Old cummins turbos make the best sound

a big fat smile from germany, i love the sound of US Trucks pure power!

Now THAT's a jake brake!!! The engine sounds like a racing car. Way cool.

that's probly the most badass truck i've ever heard

Pennsylvania's finest! Get Em Boy!!!!!!!

Yep, turbo is under boost then let off at shift, thats the noise in the exh, this guy is gettin into it pretty good

thats one of the best engine brakes i have ever heard.

The Lord of the Sounds! Thanx so much, this is a Earporn!! ;-)

this is freakin awesome thank you so much for shareing this awesome video this was a five star *** video until i hooked my pc up to my new tv wich is also hooked up to my 350w stero with subwoofers cranked up as loud as it gose gives this video a new rateing of 1 billion stars

That sounds fucking awesome, fair play. I also love the hiss of the turbo.

ohh, naughty boy :) gota love jake shifting up the gears

Correct, master switch on the dash to turn on/off. When switched to the ON position, Jacob's is activated when both the clutch and accelerator (both fitted with micro-switches) are not depressed, hence why when you change gears without clutch whilst switched to ON, Jacobs will come on for the short time your foot is off the accelerator as you change gears

dude thats awesome thanks for posting it i miss driving a truck with jake's all i drive now days are volvo's ant they are to quite.

yep thats a cummins jake get some strait pipes makes her louder

There was a really loud 5 axle kenworth t800 dump at work yesterday and today and i think it had an n14 but never got the chance to ask the driver.....but it sounded badass!

@iMcguy Hi, a turbo wastegate is fitted to a turbo to release excessive exhaust pressure from the turbo when the engine revs drop suddenly, such as when you change gear quickly. The wastegate is controlled by the pressure side of the turbo. Excessive inlet manifold pressure operates an air cylinder that opens the wastegate on the exhaust side. Turbo's working at lower pressures on lower powered engines often dont have a wastegate. Scooze me fer pokin' me nose in!

I absolutely love shifting with the jakes on. We've got at 88 Peterbilt 378 dump truck where I work with an N14 in it. Shifting with the jakes on is the probably the greatest thing in the whole fucking world. Love doing this. Jake brakes are prolly my greatest love, if I drive a truck without any sort of engine brake in it, it's like I'm driving naked lol.

my buddy has a older volvo with a n14 and a 5in straight pipe.ive ridden with him a few times hauling corn and we always use the jake at every corner and stop sign

the isx is a dual overhead cam with something called Cummins-own jake braking system....it uses one camshaft to operate the jake brake and from what i heard it works really good. The company i work for just bought a new sterling with an isx and a 13 speed....i dunno what horsepower the new isx has, but i'll letcha know when i find out

Nice sound, love straights especially on a cummins

dude this is the best jake braking video i can find on youtube... Sure is a bad ass sound man, to bad we don't have that shit over here. thanks for the upload

@bkorven The Jake brake cuts off at a specific RPM to prevent stalling, and there is a switch to turn it on/off. There is also another switch to set the strength of the engine brake (hi/low) where low would slow you down less. Kind of hard to explain without actually showing someone how it all works, but you've got the jist.

My uncles got a 2001 kw with straight 12in stacks and the best time to jake in it is with a full load of bales going down this hill about 6 miles from our house about 65 lol its pretty cool

@bkorven Yeah 82Cmb is right. Using either the freeplay at the top of the clutch pedal or the throttle pedal (just touching either pedal, so not actually engaging the clutch or throttle) or if the revs are below around 1000rpm, the jakes will not come on. So you can shift normally (no clutch) by resting your foot on the clutch freeplay or not take your foot fully off the throttle (not lift your foot off the top 5mm of travel) - takes a bit of practice. I think that makes sense...

I love this vid, nothin like a spirited country drive. awsome.

great vid...sounds awesome. An in-law of mine has a n14 in the KW

nothing beats the sound of a jake on big rigs

Nice N14 cummins with jakes sounds great

not just keeping the clutch switch disengaged, but there is a switch on the fuel petal too....if you are smooth with your foot you don't even need to couch the clutch with the jake engaged....i do it all the time

bet all the neighbors appreciate you

That sounds like my old Western Star. I miss that truck.

cant stop playing this vid and your not shy givin it shit love it. family sick of the sound

Nice! Sounds just like my dump! I have the same eng.

you see everything can be fixed with ductape

N14 The angry grunt & black smoke between the shifts 🤠

Nice Sound and Jake Brake Loudest !!!

I would have no problem doing that for a living and hear that all day!

@SUZUKIRIDERR that is correct, it does leave the exhaust valves open, thereby releasing compression...slows the motor with the truck in gear, it slows the truck.

Cummins is one of the best englines ever. Long live Cummins!

Actually Jakes will come on in Neutral. The dip settings control all functions. So if you don't have them set you will get different operations. Some wont work under certain speeds and some wont work unless your in higher gears. It all depends on how the computer dip settings are set. My truck has a Signature 600 Cummins, it works until it gets to 800 rpm and stops, but at any speed. Thats the way I like it. Some companys had their jakes set like this for their own reasons. GO STRAIGHT PIPES

Actually a wastegate opens up to regulate the pressure on the intake side. If the wastegate is disconnected the turbo will keep building pressure causing damage to the intercooler, intake tubes, the manifold or in the worst case scenario the engine. The valve on the intake side prevents the turbo from going into turbine stall and also helps drop the boost when you back off the throttle suddenly.

Well seems like many people are converting the older style full size Chevy Caprice to diesels the 6.2 GMC diesels and with the car being 4200 pounds gas mileage is going up to 35-37 mpg! I got a 1989 Caprice wagon with 257,000 miles and counting has the olds 307 in it with the 4 bbl. I am thinking of a diesel switch. I just love that Jake brake on your truck! Too bad freight trains don't have that feature! I am a foamer I do love trains too!

The turbo has a wastegate, which is what dumps the excess pressure. It activates when he hits the clutch. Without a wastegate, when he clutched to change gears, the engine would rev high because of the residual pressure.

o crap that thing is soo awesome do you see the hood twisting from torque and its soo fast and real HEAVY jakein!!!!!!!!

everytime i come on the tube i watch this vid vary sweet sound

What a beast, wish our trucks sounded like this, but we got all this euro conformity here in the uk.

lol looks like you had alot of fun making this video!

Epic Truck. Nothing can beat it

listening to this thru headphones .. brilliant !!

i LOVE this truck it sounds fuckin amazing this is how a bad ass rolls in style

FOUND IT ON A FORUM. Got one on my Cummins Dodge. Mopar actually has one a dodge truck owner can buy straight through your local dodge dealer. It's an actual "Jake Brake" as it's make by Jakob's Vehicle Systems and works quite well. CASE IN POINT. THEY DO MAKE THEM FOR PICK UPSL

That is what I am talking about that sounds really really amazing

Music to my ears! I rather drive that around all day over some quiet thing. Love the loud sound! Sounds kinda like the Balrog(Fire Demon) in the Lord of the Rings movies, they problably used truck sounds for it.

Cummins jakes are buy far the best!

The jake (full name Jacobs) brake is prevented from coming on by micro-switches fitted to both the clutch pedal and accelerator pedal, ie as you use the jake brake to reduce speed, the jake brake is switched off as you change down gears and as you let the clutch back out is is switched on again... problem is though, when you race around like this cowboy and change gears without using the clutch, for the split second when you are not depressing the clutch OR the accelerator, the jake brake starts

Love the bov, ima ford guy but my dream truck would be a f450 body and frame with cummins and an Allison transmission

People take pride in their ride and they want it to sound good unlike the guy that called you an idiot. Truck sounds great

I still love this video: what a sound!

@crunchyuncle no waste gate ...they use a variable vein turbo so none is needed.

thankfully ill probly never work on one, cummins is keeping me pretty busy, i will say i prefer the n14 to the isx though, im glad there making it a single cam for 2010!

haha,reminds me of the time i drove my uncles truck,i was goin about 50 on a 35,and got real close to a little honda van thing,and it took off when i hit the jake.i and my uncle were laughing our asses off......fun days.....

@Bigd351clevo I think I understand, what you say is that you dont either fully release the clutch pedal or gas pedal(or keep the engine under a specific rpm) to prevent it from jake braking? Seems annoying still and kind of unefficient sometimes, why not use a button to adjust the jake brake.

What's this truck? My best video of the N14 power and sound. Grates!

Dirtbike125r... Ok i gotcha now... Like you said, when you hit the throttle it turns the jake off but if you let off too much it kicks on. It just takes some getting used to i rekon, i have a hell of a time with em... I usually just go on and turn em off till i need them.

vrrooooom *shift blublublbulbiu* vroooooom *shift blublbulb* sounded AMAZING!!

In the Classics cuz i drove one, you have the options of 2 and 4 but you can also turn them both on engaging all 6 and it wont shut your engine down...I drove everywhere with all 6 engaged, just cuz its easier to slow down and doesnt wear the brakes as bad.

@SkoalBoy62 that sheew what you call it its just the turbo winding down between shifts

I like cummins but they have had head problems for years so me and my grandpa switched over to cat. Well now that they don't make truck engines anymore we are slowly switching back to cummins... Both good diesel engine makers!!! :)
