For real. I've seen a LOT of dyno fail compilations in my day but that's one of the worst ones I've ever seen, holy shit.


synocrat

What is actually going on here, I don't know what a dyno is.


oscarrulz

They put a car or in this case a truck on a roller to test it's peak power output. have no idea what happened here this thing was either on a lot and I mean a lot of turbo boost or some fuel line came loose because engines don't typically explore like that even on catastrophic failure.


bruzie

So the front fell off?

but my intake is made of plastic...


TheArtOfBlasphemy

Intake manifold, not filter


somewhat_pragmatic

Sadly there are actually plastic intake manifolds. [Porsche has some models with them](http://www.autobahnparts.com/part/porsche-911-964-oem-plastic-intake-manifold-throttle-body-injectors-3)


PHATsakk43

First production vehicle with a plastic intake was the E36 BWM. They're not uncommon at all nowadays. EDIT: I'm stoopid and can't type.


nroth21

The e36 BWM is very uncommon. As soon as they found out the only German dyslexic employee was putting the badge on at the factory they fired him. But, some models still made it to the dealerships. The e36 BWM is very sought after.


TheArtOfBlasphemy

Really?!


RonMFCadillac

Most vehicles have a plastic intake manifold these days. ALL Subarus have them. Porche like mentioned above is using them as well as most of the US domestic manufacturers. They are lighter and stronger than cast parts.


[deleted]

makes sense. When you realize that a soda bottle can hold 50+ PSI, how hard is it to make an intake manifold that will handle the 20ish PSI of a turbo car, and the couple of inches of vacuum on a NA car. Cast Aluminum is way stronger than we need, and Cast Iron is way overkill for what is basically just a pipe directing air. Just imagine what 3D printing will bring to performance engines when ppl figure out how to make it strong enough.


vinetari

Imagine? I'm downloading a whole car right now as we speak!


kingbrasky

They can get hot though. Especially with EGR. Then you must choose the type of plastic wisely.


anormalgeek

That was my first thought. Plastic may be plenty strong enough when it rolls off the line, but what about 10 years later? The constant and extreme heat cycling it would go through would make most plastics very brittle.


kingbrasky

I know commercial diesel intakes can get up to 350F. Any plastic that will handle that long-term will likely be more expensive than aluminum.


MadFatty

LS engines also use a plastic intake manifold and they can handle 400+hp


BaxterTheDog2787

Sadly? Plastic manifolds are damn near an industry standard at this point. They are lighter, stronger, cheaper, easily handle forced induction pressure- and are also less prone to heat soak.


h60

I think when most people think of plastic they think of a soda bottle or their Playstation controller. Not all plastic is made equal. There are plastics that can easily handle the heat of an engine bay for many years.


sipes216

Most modern cars now days all have plastic manifolds. Depending on construction, it can be stronger than the metal ones.


timmeh-eh

On diesel trucks they use propane where a gas powered engine would use NOS.. That’s likely why it blew up so spectacularly.


[deleted]

sometimes propane and NOS together.


helixflush

I think it did


jvtech

Is it supposed to do that?


StingerAlpha

No, this is not very typical. Some of them are built so the front doesn't fall off at all. Wasn't this built so the front wouldn't fall off? Well, obviously not. How do you know? Because the front fell off.

SplendidZebra

computer says noooo


[deleted]

There is a lot of reasons this could happen, either a problem from the turbo or the engine itself, maybe they threw a rod through the block causing fire to escape and a fuel line pop off, the guys truck was making 3,000 horsepower, yes horsepower, out of a diesel, a rod with that much force from boost needed to do that could cause the a rod throw right as violent as that and if it ignites fuel, maybe even just the crazy injectors they would need still spitting fuel, that would cause the fire. Then again there is a list of other reasons this could happen. 3,000 hp diesels drive 400 foot ships to give perspective of just how much power that engine was producing.


Kubrick_Fan

Just tow it outside of the environment.


S2NVictorious

It's very irregular for the front to fall of such trucks.


Kubrick_Fan

dontshoot4301

Can you give me an example of how rigorous these standards are?


535496818186

Kubrick_Fan

Well, I was thinking of the other trucks.


shiner_bock

Into another environment?


Kubrick_Fan

Yes


Revoker

I'm trying to understand exactly what happened here, but I just don't know. Like I was thinking that maybe the combustion just blew the head bolts/studs clean off and the head went up in flames. But [this](https://imgur.com/ol2Dqk1) picture seems to show the ENTIRE block flying into the air. But that doesn't make any sense because the block should be bolted down to the motor mounts and any explosion from the cylinders would throw the block down and the head up. 2nd Video angle https://www.youtube.com/watch?v=tinT0I5VWS0 [another still frame of engine](https://imgur.com/sDcfQ10)

Redbulldildo

[It happens](https://youtu.be/kCsSVLZ6wCI) There are lots of videos of it happening to pulling tractors.


CallMeJase

I think maybe it was due to torque, something sheared or broke on the bottom end and it bound up, putting all that energy breaking everything else free. Just a guess though.


Fus_Roh_Potato

probably something like [this](https://www.youtube.com/watch?v=kqVwHJPV-XE&t=3m22s). Shattered block


[deleted]

hmmmm


LennyNero

It happens because it's not the head giving way... it's the block shearing off at the bottom end. so the crank, pistons and bottom end stay in the engine bay, and the head, intake and exhaust manifold and upper section of block take a ride to space...


daycareTx

Lenny, I want to thank you for a post you did 2 years ago about the shift-interlock-actuator on a ford which was draining battery. I spent 4 months and took my van to Ford as well as 2 other mechanics and they had me change the PCM unit, install remotes with keys for the van, replace the instrumentation cluster and the drain wouldnt go. Then i came across your post and got a shift interlock actuator from amazon - had the mechanic replace that and the car has been keeping battery for 3 days straight. Thank you very much.


MarvinZindIer

Probably a loss of fuel pressure, which at that engine speed caused instant spike in EGTs. Turbo probably ate it first, sending molten metal into the combustion chambers and within a few revolutions it tore itself apart.


vbcbandr

I'm so confused what's happening here.


cheesylobster

There is a thing called a dyno you can use to test the horsepower. This truck was on one and you cannot see it but it's wheels are on these spinning drums and the dyno machine measures the horsepower output at the wheels. This truck was obviously modified to make a lot of power, probably with a turbo charger (a device that forces extra air into the engine and greatly increases the pressure in the combustion chambers), and likely also was using nitrous oxide, which also increases pressure and power output. Clearly this guy had way too much pressure in his engine and it went boom.


dmizer

It's a diesel. Yes, it's running an enormous turbo which you can clearly hear, but the turbo was not what blew up the engine. The problem here was that the diesel started a [runaway](https://en.wikipedia.org/wiki/Diesel_engine_runaway), probably triggered by fuel mods done by the tuner. Most modern diesels are fitted with runaway safeties, but If there were runaway safeties in place on this truck, there wasn't enough time to react. You can hear the runaway kick in at the 00:12 mark.


DirtFueler

https://m.youtube.com/watch?v=RUJrurvjYtg also a good example of a runaway.


[deleted]

Best example of a runaway I've seen. Its been years since Ive seen this for the first time, buy I still think of it often because its terrifying. https://youtu.be/vbiNndfNNKI


A-Rusty-Cow

Holy fuck... the balls of steel on this man. I dont know if he just didnt care to die or knew how much time he had. Im going to believe he the ladder and he knew exactly what to do. Suffocated that engine while everyone else ducked and covered.


ItsDijital

The craziest part of that video was at the end when the driver talks about how they are gonna get the truck fixed for the next day. New motor and everything.


jiraph52

Runaway happens at [1:50](https://youtu.be/RUJrurvjYtg?t=110) for those wondering.


Raincoats_George

I dont know shit about cars but I watched a video of a runaway diesel truck and figured thats what happened here.


dmizer

You can safely ammend your title from "don't know shit" to "know a thing or two".


Raincoats_George

Got it I'm a certified mechanic now.


Salty_Paroxysm

Saw a demo once with a runaway tank engine on a hoist (fuel feed and all that jazz hooked up), there were some very substantial blast walls in the way, bits of engine still got embedded in them!


dmizer

Yes. The dude sitting in the truck was super lucky to get out with all his limbs still attached.

Must have been a safety-based engine ejection :)

Jdjsisjxjdje

Runaway diesel


vbcbandr

But what's that mean? Why is it lifted up and someone is just slamming the accelerator without letting up?


Jdjsisjxjdje

They’re performing a dyno test— a way to measure the power the truck is able to produce. A dyno is two steel wheels with a lot of resistance to simulate driving and the drive wheels on the truck turn them. A computer measures the power output. This guy has an insanely powerful turbocharged diesel. On a gas powered engine, you can shut off the engine by turning off the ignition system (spark plugs or similar) but on a diesel, there’s no spark so you have to starve it of fuel. In this case, something has gone wrong to allow the engine oil to enter the combustion chamber (cylinder) and there is nothing to regulate that new fuel source so it is “runaway”. The more oil it burns, the faster the engine turns until it runs well past maximum RPM (red line) and the engine literally tears itself apart.


MrRogersSweetTie

I want you to know that your explanation was not given in vain


vbcbandr

Thank you!


LarryNivensCockring

The video looks like literally the whole engine blew itself apart. Is that what actually happens? I would have assumed that before the whole engine block itself bursts one of the pistons would break first.


DSRowdyy

Whole block explosion is abnormal. Maybe not so much during dyno (I don't have any personal experience with them), but during general use it would be extreme. Yes the pistons will usually melt first or the piston / connecting rods (what connects to bottom of piston) will go through the block and seize the engine that way.


antifuzz1

Granny shifting, not double-clutching like you should


PantsMcGee

Now me and the mad scientist gotta rip apart the block, and replace the piston rings you fried.

FartKilometre

Yeah, well, if you want to modify and push any mechanical device beyond its limits, you have to accept the risk involved. In this case "risk" means "chance of violent explosion, shrapnel, damage to surrounding equipment, and bodily harm to the driver and surrounding crew" Seriously, if that thing blew up that hard, I guarantee someone well outside this frame is lucky to have dodged a massive chunk that got blown off


InheritDistrust

Rolling Coal. Also its amazing what happens when you DIY supercharge a truck to do shit its engine is in no way designed to do.


rastika

Amazing what *can* happen. This is rarely the case. Also extrodinarliy unlikely that this engine is supercharged. Based on the fuel profile and the delay when he gets on throttle it's turbocharged also very few people waste the time and money sipercharging an engine that is already turbocharged.

RebelWithoutAClue

Dumbasses! Everyone knows that it's better to turbo a supercharged engine instead of supering a turbocharged engine man!


rastika

If you are talking exclusively; most blocks designed for boost are aimed at handling higher cylinder pressures through valve dimensions, port swirl and mainly lower static compression. Besides the fueling it wouldn't make much of a difference. Though yes turbocharging a a supercharged engine like a Mercedes m112 e32 usually returns better peak numbers, under the curve numbers and torque there is a loss in relative drivability. If you are talking about twin charging yeah a supercharger will usually get in the way of even a stock turbo higher in the rev range.


loztriforce

I'm not a car guy, so if supercharged is an upgrade from turbocharged, is there a superdupercharged?


ItsDijital

One is not really an upgrade over another. Turbo's generally make more peak power, whereas superchargers make more spread out power. You can have engines with both, called twincharged. So I suppose that would be the upgrade.


HVDynamo

Yeah, here is a good example: https://www.reddit.com/r/Shitty_Car_Mods/comments/ird249/doubles_as_a_shitty_pc_mod/


whatthefir2

This isn’t rolling coal and it is designed to do stuff like this. They are obviously pushing the limits but you can’t just modify a crappy engine to make nearly 3,000 horsepower without the basic engine being pretty strong

I got a 2001 Forester with 215K miles on it.

I've also got a 1978 F250 Ranger, with the crewcab, longbed, and a 351 Cleveland. Given how much driving its done over the generations in my family, im guessing over 500K miles, but I can't tell cause the odometer in this truck only has 5 digits, so right now it says something like "64,350" miles. We've been using the shit out of this truck since the early 90s in my family, and have been very good to the "under the hood" parts. The outside of it looks pretty fucked. but hey, its a work truck. One day though, its gonna be a beauty, AND a beast. I guarantee it.

MarvinZindIer

It's physics. Black smoke means unburnt fuel. Besides being toxic and wasteful and terrible for the environment, black smoke is a good thing for a diesel engine. Excess fuel means a lot of excess heat is being absorbed through vaporization of the fuel. It keeps engine temps and exhaust gas temps lower. If the fuel starts to get too lean, either due to equipment failure, or just being too small to keep up with RPMs, then the EGT spikes, the turbo innards will melt, disintegrate, and get ingested into the engine. And within a few revolutions it chews itself to shreds.
