- Triple turbo Cummins dyno session gone wrong!
This was going to be the last dyno testing session before we pulled the engine out for a refresher. Well, its now much more than a simple refresher!

"Oh look, another video where they show the dyno pull, call it carnage, and show nothing of what went wrong...wait...9 minute video?"
Thank you for the pull, and the carnage. But not just that, but also the analysis and thought-recall of what went on. This is truly interesting and informative content.
Yeah, just so many people throw up a video, with "carnage" in the title...but don't show the carnage. Those that do? I don't know if I have seen any that actually show a teardown and analysis of what went wrong, or how they plan to fix it, as you did.
So, thank you. Great content.
Goldmarble did you not see the broken camshaft dummy?
@@queasyislander0274 Did you read my entire comment?
Not going to lie. I see your videos in suggested and always skipped them thinking they were click bait or ads. Boy was I wrong. Tonight I’m going on a binge watch if this channel and hitting that sub with the bell. Great content and I enjoyed the whole video. I think this was the first diesel related video where I didn’t skip past the filler bull crap talk. It was entirely action or information pertaining tot he action. Very nicely done and you got yourself a new sub
When the pistons were hitting the valves, my subtitles said [Appluase] 😂🤣
8:45 [Applause] 🍻👊 I am new here and I love the power you guys make with these diesel engines! My dream car is a jeep grand Cherokee Trackhawk. I just think it needs a diesel race engine instead of gas now! 👊🤣😂
I feel like you guys need a bigger audience than this you guys are doing a great job here and cant wait to show this in class monday
Texas Performance Trucks its to professional and televised style for the audience. I love it
TrollMaster300 lol think your right bud
It’s weird how you guys don’t have too many subscribers the quality is great on these videos
ThatGray24v your right they have good quality video good speaking voices and explain with retail... wish my videos that i make are like this
They just brought on a new guy not too long ago to handle videos and such.
yea I agree. but this isnt popular to people. people would rather watch rap videos smfh.
Dress for the job you want, not the job you have

These ole boys are the best i have seen professional stand up guys that know what they are doing! Keep it up fellas we appreciate ya
Huge fan!!
“Mechanical mafia” all the way boys!!!
I like your positive attitude towards everything
I watched this on your Instagram the day it happened. Glad it wasn't more catastrophic. Hearing that engine whine down from the kill point hurt my heart. Can't wait to see what you guys come up with next.
I like your team's attitude.
Best attitudes in motorsports , hats off fellas great you tube guys
. ...doesn't really look like it, but you guys are straight gangster!
That was nuts.
Full send it!
excited to stay tuned to the rebuild process! great video guys!!
5.9 Cummins can take a lickin and keeps on tickin if it breaks it can be put back to gather easley
good vid! It's great to see "cause and effect" videos with substantiated thought as to the 'why' and 'how' and not just "look, we blew up our engine today"! I'm no longer in school for this but you could do vids on the technical side of things, math, clearances/tolerances etc. just subscribed!
at least its not a 53 block! nothing like a walking cam. I used a stud and blue locktite.
on all those parts especially if I was like you guys at 2400 horse what the hell man hats off to ya.
at this point in the game I salute you keep going and breaking stuff, my pockets aren't that deep lol.
Ok guys we need to think about this a little bit. That white smoke started many revolutions before the cam ever broke. Something was happening there that may have contributed to the cam breaking. Like a lifter seizing in the bore? Valve seizing open? Something happened before the break. Of course it might also be directly related to the cam being out of position due to the thrust screws stripping out. Hard to say without seeing it in person.
can't wait to see what it makes hopefully it stays together for you. always innovating.

Uytyyesaa hi j.lo lllĺ0oppp is piosoosoowoaosooaao
I got a 1990 f2/350 that I'm eventually going to swap to a 12v. At the moment it's a n/a 7.3. U guys make me want to go tear into the thing right now
It's a 7.3... I got plenty of time
Great vids. One of the main reasons why I will buy my compounds from yall.
This is better then Greg A content !!!
Looks like it might need an align-bore hone from that one main bearing down to the copper. Id also want to know why the cam broke. If your spending big money Id probably send it to a metallurgist for a fracture analysis. Id bet probably the screws came out first and then the cam snapped once it surged forward from the thrust load of the gear teeth meshing together. Timeserts would be a good investment since they are hardened and will give a larger diameter thread in the block to hang onto. Id say the heavier springs are what did them in since there is more thrust load on the cam.
Todd is the Tom Nelson of compression ignition , swear to God 👍
Thankfully the cam failed while y'all were toying with it on your shop dyno. Better there than out at the track or while pulling a sled.
Kick ass video gentlemen. Keep up the good work!
I’m watching all the videos. Hopefully it’ll help and get these videos circulating more.
I saw you on Finnegan's Garage and think that I had seen this truck on an earlier video so subbed.
This was an awesome vid. Yall got my sub!
Reduce cam helical gear thrust with opposing helical or straight gear teeth setups.
@@pddofficial pay the guy .its a lot V of work to make proper hobbed gears.also the cam would really appreciate it
Great videos guys!! Keep them coming!
Best video yet! Keep it up.
Cast camshaft or steel billet? In case of cast camshaft, drill the hole for the cam gear deeper in the camshaft. Preferably to next bearing where there is meat.. if you market thread there...the snout is pushed to the camshaft together with cam gear. Instead of now ,, or most of the case with tractors and truck engines...it is pushed to the snout only and breaks of easier as cast material is not ment to be pulled or bent. With the longer bolt ,the clamping force of the bolt will prevent that happening. Greetz f Netherlands... Keep up blowin smoke!!
@@pddofficial 👍👍
Another awesome video! Thanks.
you guys crushed the sled pull 326 feet is nuts
i notices the thrust washer main in the middle was thru the babbit into the copper crank walking with cam or ????
Did I starting fluid being sprayed into that engine? When it's cold and hard to start in the morning, I always use WD 40. Works great and is much safer for the engine.
Awesome stuff. Keep it up!! And thank you
Subscribed , great channel look forward to more vids keep up the hard work guys,
So where DID the oil come from?
MikMech I whould say valve guides or cam bering but my opinion whould be the bent valves valve guides
Cheers for the info
I was wondering that too... Now I know.
Back to the drawing board !!!!
How only 5k? This vid quality is dope
PowerDrivenDiesel I’m actually saying “how does this channel only have 5k subs, the video quality is excellent and huge production value”
Peak in cylinder pressure at full load? How much of that is left at bottom dead center? Cam pushing an off center lifter and trying to open exhaust valve after power stroke against high cylinder pressure busted thrust bearing retainer bolts would be my guess. Or the helical gear thrust on cam gear from same load.
Is it possible that a valve touched a piston while on the opening ramp of the cam? Because that would cause one hell of a bind.
golly, where does the endless supply of dollars, come from, I must have the wrong job
Why does nobody use piston sleeves which stick into the head to avoid head gasket issues?
You guys ROCK
@@pddofficial From where do you guys hail?
Bravo for the cool head when it handgrenaded I've had engines fail but never at this level of H.P. just me drivin the shit out of em...cars and dirtbikes
great quality vids very informative and fun to watch and learn new sub
Y'all are professional
Why was there so much wear on just one of the mains or was that just camera lighting? It looked like I believe #3 main was wore down to the copper while the others still had the majority of the coating on them. I love that kind of R&D as well. The kind of stuff where half the people you talk to about it say "that won't work" or "you can't do that". Once again love the videos.
It is amazing how much flex there is when you are at that sort of power level. Wow that's too bad. I know some people like those carnage video's but all I can think about is all the hard work and money that went into that engine and is now gone. Of course I guess that is to be expected when you're in uncharted territory.
I still don’t understand why the camshaft broke
How can it pull the thread off the camshaft?
the gears are cut sideways, it pulls against the cam when under stress
Love your intake manifold, who makes it?
Todd have you any tuning tips on a 2003 Audi a6 diesel 1.9tdi
they didn't let it warm up!
Iv seen all your videos on this truck and I just realised it looks just like my truck lol
This is bad@ss you boys don't waste no time and play around, great video too!
But will it pull my camper for 200,000 miles? 🙃
I love these guys! I've learned so much over the last year from watching yalls videos. I have AFC Live & PDD Cold Air Intake on my 12v compound turbo Cummins. What I wouldnt do to apprentice with these guys.
That's what happens when you try to polish a turd.
So bottom line is,the cam retaning bolts were too weak?
I get you,so what's basically happening is that when the engine revs up quickly the helical gears are causing a 'pull' on the camshaft?
How does a diesel rev so high? Or how are they reving higher?
They make 5000rpm cams for the Cummins 12v. And I think pdd has a custom 7000rpm cam (!)
2400hp on a diesel and “why did the cam break” 🤣 I have a guess
3:42 Looks like the number one cylinder rocker tower is cracked down the middle. BTW, where did you get the roller rocker arms?
manton makes them but roller rockers aren't intended for street use
Im pretty sure they are harlen sharp
Are you guys upgrading to a SMT system or something similar?
Just to clarify here I didn't know what roller rockers they were using just suggested where I knew you could get them.
The PDD logo looks too much like the Ford powerstroke badging for me to take it seriously
What causes the cam shaft to force out like that? Is it just the cut of the gears or did the followers have something to do with it?
Definitely the gears. They are not straight cut so helical pressure angle produces axial force on the cam, which is why a retainer is used to minimize the axial play. The cam will become longer after the break because it wont be a clean break so that uneven break will force the two halves of the cam apart too. That is what really contributed to pulling the retainer bolts out of the block.
if you notice too they had the gear welded onto the cam to keep it on the cam itself. The older cummins engines with the helical gears were known for slinging the gear off at high engine load and speed.
PowerDrivenDiesel when do you need to start to worry about that? 13mm pump or a maxed 12mm?
So is it more effective to run a filled head and block vs a coolant system when you're trying to save weight to make a faster track time? Obviously, you cant run it very long, but does that create even more problems than it's worth?
Hi what happened to the other engine which was the 6.7 with warhead from Hamilton came u'll were running for the truck? Is it coming back this year ?
Wow a 12v 6.7. So the all aluminum drag engine wasn't used
This truck blew up theres a video on another channel from august
how much boost does this make at 2400hp
200psi
You blew the fuck out of it not long ago lol.
I want more!!! Lol
badass
Wow. That's a lot of cash .. geez...
Nice videos subbing for sure
And I can't even get my 6.4 out of the shop. Going on 1 year.
PowerDrivenDiesel trust me, stay far far away from a 6.4
You would think in this day and age you would wear nitrile gloves when handling oily parts. But it's your life, your health. Do what you want.
valve train and piston return springs at fault!
12K subs?? WUT?
The repair bill just keeps getting more and more pricey as the video goes on...RIP
Not sure the EPA would like this
Dam
Not many people sub to this channel because EVERYBODY KNOWS,there is such a thing as"structural capacity limits".You cannot build ANYTHING past its structural stress limits and after that,the device becomes a bomb!!.
Safety live with it!!.
Damn
Todd I would embarrass you in my 600hp duramax 😂
PowerDrivenDiesel haha good luck bud!! Next time she will purr I’m sure.
Race banks duramax lolz
Don't see the root cause?
53 "gassers" watched this video..........WINK
One cylinder has as much horsepower as a Mustang lol
What ugly pollution through the exhaust pipe !
wrong
I am sure that you love what you are doing but apparently you do have a ton of money to burn.
For all the talk about the engines and oil all over it would be cool if you guys would actually show more of what you’re talking about. Like you spent 3 minutes talking about the carnage and you you showed us like a 1/4 second glimpse of the engine in the truck.
I mean you guys aren’t ugly but you’re not as pretty as the engines. So please show more engines is what I’m asking you for. Thanks!
❤️💋💕💘😈
P.S
Too much black smoke. That means you’re wasting power! Tune it better.
@@pddofficial Hi there with greatings from Germany, on a gas engine ou would be completely right, you go lower with Lambda and richer on your AF ratio to cool things down.
That´s why trubo engines are real gas guzzlers at WOT. But doesn´t in a diesel engine more fuel make more heat? In a lean situation you simply don´t make that power but you are not in danger to melt a hole in the piston right away. Does more diesel help to keep EGT´s down? Totally new for me, I always thought it´s best to find the sweet spot where it has fuel enough but just starts to smoke. I would realy appreciate your thoughts or better your knowledge to fresh up my ideas
Hah, I can do way better.
That is exactly what I have been thinking since I have sub'd!these guys are professional and know what they are doing!why in the world wouldn't they have 1,000,000 subscribers?!I am fixing to post the video on F.B...and help these guys out!
DuraMAxFanatic because it’s diesel. Every kid is into petrol I like both. Plus there is that many racing channels it’s boring yet it still pops up in your recommended. My advice please don’t post it to your 4 friends.
What caused that one bearing to be copper color and the rest were normal??
PowerDrivenDiesel, oh wow! Seems like y’all got relatively lucky! Don’t get me wrong, it still sucks but it could of been way worse.
PowerDrivenDiesel, it great to see all the detail and time you put into the truck.
@ PowerDrivenDiesel so why did the cam break?? why did it walk out of the block ?. is the cam tunnel off (the line bore) or the bent crank, broke the cam or the broke cam bent the crank ????? i know theirs a helical gear but i tout that under rotation that it forces it back into the block if not a cam button may help we run them on the 6.7 john deeres
Great video and cool for you to share, maybe this help others avoid the same problem if they happen to be running 24,000 hp. ; )
PowerDrivenDiesel so what wad the grey streak in the exhaust?
24,000hp, think you added one to many zeros. 2400hp.
Love how you guys focus on 12 valves.
Race it, break it, fix it. Repeat... love the attitude. You race, chance horse power you’re gonna blow it up at some point.
What was the gray column of smoke? My guess, stuck valve and unburned fuel.
3:54
That's a real big bill....
Hate that bill.
I know I shouldn't but... How many times have you paid this bill? :P
To many times but that is what happens when you are pushing the limit of parts
man, I love your videos, cheers from mexico!!! you are awesome!!!!
Don’t know if anyone mentioned it but the cam looks like it had a bad heattreat. In the shot were you show stub connected to the cam gear the outer grain size appears much larger than that on the inner core. If that’s accurate it means that it was overheated and/or heated too long before the quench. I do know a little about the subject.....
However is there any sign that a lobe might have locked onto something when it was out of position due to the thrust issue?
My thoughts exactly. The bolts for the cam retainer were only forced out when the cam snapped.
When an interference engine loses that synchronization it can cause serious damage bent valves destroyed pistons etc.
