a simple blockage in the exhaust extractor unit. did you see the pipe expand!, all that induction pressure plus the back pressure. the smoke came out of a oil breather showing the pressure went past the ring down to the crank housing.
@ipadize It's short for "dynamometer." It measures the horsepower and torque that the engine puts out through its rpm range, or "powerband." This dyno hooks up directly to the crank to measure the power of the engine itself; another popular type is turned by the wheels of a vehicle to measure how much of the engine's horsepower and torque is actually reaching the ground at the wheels.
It's so easy to say why didn't they shut down when the black smoke appeared (and I'm sure they wish they would have) but, were talking a few seconds here and isn't one of the reasons for a dyno pull is to see if the motor is capable of doing what is excepted.
@shsn25 the exhaust valves probably expanded and locked open the intake valves then probably did the opposite, locking in the turbo pressure that couldn't enter the blocked cylinders and all that pressure had to find somewhere to go...
i dunno ifanyone else noticed it but it appeared a poof of steam came from what to me appears to be be the water pump right before it came all apart. i was wondering if maybe all that boost pushed the headgasket, filled the water jacket with all that boost pressure, and hydrolocked the motor with coolant at tilt? maybe im over anylizing the vid?
When the engine starts to pull down it's because the operator is loading the engine and stabilizing it to start the pull. I know many don't realize that pulling a engine down, or below, max torque peak on a dyno can be harder on a torque engine then reving to max HP. The vent pipe is only moving because the engine is belting out a lot more exhaust and heat despite the fact that the RPMs are declining against a load.
The idea that the dyno operator did this is ridiculous... unless the operator built it... If so, he's a blooming dumbass... that engine blew up for a reason. Will we ever know? Hopefully...
And what exactly was that? The tiny little bit of soot from a TINY little exhaust leak? lol. Or the exhaust duct standing at attention when a thousand or so horsepower worth of exhaust flow started jumping through it once the charger lit?
Watching the video, NOTHING was blatantly wrong with the pull. The timing didn't sound horrendous, and it sounded smooth. Maybe the timing was a bit high, or maybe it was just a weak block, but there was NOTHING to say abort the pull.
0:14 you can obviously hear something is wrong! Smoke and the engine struggling should be enough of a reason to stop a run. "approved tuning center"? I would not take my engine to a place that doesn't use their brains. Paying closer attention would have saved the customer a 6thousand dollar loss.... Or how ever much that engine costs.
@Rocketogre Saying I don't know how an engine dyno works based on nothing is completely stupid... If that engine sounded good to you towards the end of its life then I hope you have lots of extra cash lying around.
I'm curious as to why the fuck the guy in charge of the dyno carried on after piles of black smoke started to appear at the same time as the exhaust fan started to bloat? There were 6 seconds from when that happened to when the thing completely fucked itself. Plenty of time to shut down and inspect. Fuck sake.
@o1Chiefo1 You ever see one of these bad guys pull? Lot's of smoke. I wouldn't expect anything wrong by seeing a slight leak of smoke coming off the turbo. And I'd assum the engine slowing down would be the dyno putting load on it.
@o1Chiefo1 Black smoke pouring out everywhere is quite normal at pro(?) stock tractor pulling. These diesels are highly supercharged and fitted with massive fuel injection pumps to get their horses. Stay bolts breaking off by escalating boosts is an established problem in this context but hardly predictable. The engine ran fine to the bitter end. Just bad luck...
Iif it were exhaust pressure it would have blew the manifold off not the head! I have blown the manifold off my 12v before so trust me i know from experiance! You are all idiots!
God you are all a bunch of morons and i like how when someone like me with a little bit of knowlege comments it gets deleted the proplem was not weak head bolts non oringed head too much exhaust back pressure ect the problem was the duno operator loading the engine to hard causing excessive cylinder pressure!
Just curious as to the amount of boost this engine was being fed. I'm looking for actual amount, not "alot", or more than it can handle. This was obvious. Thanks. This is an actual question btw.
@KristapsE36 Wrong answer! it blew because of numerous reasons. not just one. maybe faulty engine assebly, not the right parts for the build. or alot of other things. it could of blown because of one little loose bolt.
6 secs before blow up you see the first isues that somethings not right. Why they forced to continue the test? Are they blind? Or just wanted to blow it off?
@stepseldinski I did see it too, but i bet the engineer was too occupied with the instruments to notice. First went the head gasket, then the bolts and then the whole cylinderhead took flight. Someone was beeing to cheap when he ordered the gaskets - or to weak tightening down the bolts - one or the other or both.
@doomdayjudge That's a point. But it seems like you can hear it good enough that it won't took revs. And the guy on the cam seems to hold it in the hand (stands in front of the window?). Who knows.. :) Anyway..good to see it on the dyno and not in a car.
The exhaust pipe from the turbo charger expands and clearly almost explods, But there not enough preassure to crack it wide open. insted air finds another place to come out if it cant get out of the exhaust pipe. the reason why it goes wrong is. the exhaust pipe is clearly not letting enough air out to let the engine rev that high. but they dont stop trying to rev it up and then the preassure gets so high it pops the Cylinder head of. to mutch preassure.
@vaporator1 an increase in backpressure past the turbo would cause a drop in efficiency of the tubo, limiting boost. besides, what do you think is going to break first, a rubber tube or a bunch of 5/8 steel bolts? plus, if you build up too much back pressure, it will just kill the engine because it cant draw in any fresh air into the cylinder because it cant get rid of the exhaust.
@vaporator1 it doesnt expand, it lifts upwards a bit. Its a snorkel from a ventilator, there is no backpressure in that system. Its part of the dyno room, not the engine.
@vaporator1 by the way thats a cummins turbo diesel, running compound turbos spraying meth and or propane and or nitrous. His boost pressure is likely 120+psi, not to mention spraying the meth or propane or whatever to keep her cool. The vent pipe lifts because of the massive exhaust plume. Ever seen a pulling truck spool up? LOTS of smoke.
The pipe exhaust pipe from the turbo charger expands and clearly almost explods, But there not enough preassure to crack it wide open. insted air finds another place to come out if it cant get out of the exhaust pipe. the reason why it goes wrong is. the exhaust pipe is clearly not letting enough air out to let the engine rev that high. but they dont stop trying to rev it up and then the preassure gets so high it pops the Cylinder head of. to mutch preassure.
@oldayz545 thats an exhaust pipe, from a powered ventilator in the dyno room. It does not expand from the boost pressure. Thats a cummins turbo diesel engine that exploded likely from propane or nitrous. Usually when the head pops off like this, is because the block failed and let go of all the studs, as opposed to all the studs breaking at the same time.
@GTAstuntking pretty sure he was running beyond what arp studs could have prevented, probably O-ringed heads so he could run that massive amount of boost.
@juggnautbitch you two are retarded, thats a cummins turbo diesel, running well over 100psi of boost before it took a shit. Likely lunched the block and thats why the head flew off. Those are compound turbos, not twins. One is reboosting the the boost from the other, allows the trucks to run massive turbos and very high intake pressures. That was a nasty ass CTD before death, im sure he has other vids.
@DragonFlyback256 i really doubt the exhaust was clogged, just a hell of a lot of gasses moving through the system. besides, looks it was the head bolts that gave or were pulled out of the block, and if the exaust was plugged it just wouldnt have made as much power because of the restriction.
Probably you are right. But something really restricted the flow somewhere as from a point rpms started to drop despite of the boost kicking in and you can hear a rod knock of sorts even. I'm not 100% in what made the knocking but from that point you hear the turbo spins up the sound of the engine changes and does not sound healthy anymore. Weak head bolts, yes, but WHAT is causing the overpressure?
@DragonFlyback256 i think it was just simply too much boost, maybe due to a faulty wastegate or too high of a setting. there was just too much pressure from the combustion process and caused the head bolts to stretch, then break as more boost was built. another possible situation was some inexperienced engine builder decided to overtorque the head bolts in attempt to hold the head gasket better and keep it from being pushed out, thus overstretching the head bolts and weakening them.
That's a good guess as well. Still doesnt look like overboost to me. But, my guess is this is a diesel engine judging by the sound, so it's not as hard to overboost one, heh. =Đ

I wonder if there's a muffler on dyno exhaust pipes. Muffler collapse on 0:01 perhaps? I just can't imagine what can clog an exhaust up this bad.

@DragonFlyback256 i really doubt the exhaust was clogged, just a hell of a lot of gasses moving through the system. besides, looks it was the head bolts that gave or were pulled out of the block, and if the exaust was plugged it just wouldnt have made as much power because of the restriction.

Probably you are right. But something really restricted the flow somewhere as from a point rpms started to drop despite of the boost kicking in and you can hear a rod knock of sorts even. I'm not 100% in what made the knocking but from that point you hear the turbo spins up the sound of the engine changes and does not sound healthy anymore. Weak head bolts, yes, but WHAT is causing the overpressure?

@DragonFlyback256 i think it was just simply too much boost, maybe due to a faulty wastegate or too high of a setting. there was just too much pressure from the combustion process and caused the head bolts to stretch, then break as more boost was built. another possible situation was some inexperienced engine builder decided to overtorque the head bolts in attempt to hold the head gasket better and keep it from being pushed out, thus overstretching the head bolts and weakening them.

That's a good guess as well. Still doesnt look like overboost to me. But, my guess is this is a diesel engine judging by the sound, so it's not as hard to overboost one, heh. =Đ
