I appreciate your honesty in failures and ability to work past them. Thank you for your time, effort and everything you do
I second that!
Yeah and they're the same way with customers. They're honest and stand behind them.
“It didn’t break. This uhh.... Hamilton cam”
Smooth plug.
"Then I get lookin and I see the camshaft ".
"Every failure is an opportunity to build it back better" this is the perfect attitude, love it! 👍
it sucks that your truck blew up, but this video is just another example of you guys providing the best technical content on youtube. i love your videos and hope to see many more in the future, just not about blown up trucks.
I love how you refer to 1200-1800 horsepower as mild. That's just Awesome. You guys really are be-awesome (Bolt). Thank God you all walked away. My Dad used to run super-stock and it was something like this that got him out of racing. Had a front tire that was getting dodgy but thought he could push it through one more race, lack of funds for him lack of time for you. He had just finished building the car and the engine and after setting a lap record on his qualifying he lost that tire and totaled the car.
Is this Cleetus McFarland in 20 years?
Thomas.....He does look like CLEETUS
8200rpm on a Cummins?? wow.
That's scary... 158 pounds of boost going across the finish line!!! Runaways are bad as it is, but I'd be shitting a brick going 140 in one.
Heard shortly before yeeting down the line:
"Yee of little faith, behold! The 1800hp 53 block!"
AHH THE OLD 53 BLOCK.
FORGOT ABOUT THAT ONE.
Cant believe I found myself glued to this video of two guys talking it like it was a Tom Clancy thriller. Glad to see you walked away from this and with composure to boot.
You tested the sh!t out of those parts!! It's amazing how much pressure and power is really happening inside of these diesel engines and they hold it just fine. Like you said nothing would have held or survived the pass u did there and it was far beyond normal operating parameters but it's still crazy how much these things can take and still go. Most importantly you and everyone else came back in one piece!!
The way that block separated you'd think it was a John Deere! Glad you guys are OK! You're taking it really well all things considered. I can't believe the fuel would even burn fast enough to achieve 8200RPM! That's just crazy stuff right there. Thanks for the video!
@Captain MufDyven it rolled coal all the way to the BANG.... it cant have been lean :-P obviously more than enough diesel going in, which is incredible considering the boost level. That is one serious fuel system
Best in the 12 valve game!!! Love what you guys do!!! Hell of a product and service!!!
You two guys are a fabulous combination, so articulate and wonderfully understated. As an Englishman, it seems to me you could almost be English!
Thanks for Sharing this with us on such a personal level. The way you guys make your videos really makes you guys feel like our friends hanging out at the shop. Your level of Commitment to the diesel community is top notch. Keep up the great attitude and professionalism and you guys can do anything. great seeing your wife's support too! You guys definitely have a cold beer waiting on ya if you are ever heading threw Alabama.
I've said it before and I'll say it again. I absolutely love your channel's videos. I typically never "thumbs up" a video but they're always the absolute top when it comes to production. Stay safe out there guys, next time you're in AZ I would love to watch you at wild horse pass (missed ya last time cause of work.)
creased at that intro, love your channel and the detail you go into. its great that you can laugh at yourselves, its one of the things that makes the channel great
Im glad you weren't injured. Metal can be bent back or replaced, people can't be.
Couldn’t agree more!
Just thinking about the emergency shut off not working. Is it possible it simply couldn’t work against that 150psi boost pressure ??
Just thankful you’re ok because that could’ve been a lot worse Todd. Someone was watching over ya brother. Ya live to blow another engine up. Keep up the great informative work guys !!’
Good explanation of what happened. I wouldn't re-use the pushrods though since they might have internal stress fractures that you can't see.
Keeping up with these guys has been a blast. I love FirePunk but I’m a Power Driven Fanboy now. I love hearing about the ups and downs and never quitting of this team.
Thank you for responding to a question I left first time I've ever got a response. Good to see your not giving up but making it stronger lighter and faster!! Look forward to what you build
years back in 70, when i worked for cummins there was a semi, with the 855 engine carrying 30 tonnes of the same explosive that blew up Oklahoma City, the truck caught fire, ammonium nitrate, when the explosive hit the burning diesel the thing blew up, story goes the detonation could be heard 100 miles away, biggest piece found was the crankshaft
Remember that news story
Still think you all should change your trucks name to Murphy's Law
Next time one breaks the fireball record ___
6000rpms on a 150 lbs forged crankshaft 6bt yeaaaa.
You guys are amazing! Thanks for doing all these videos!
All things considered an extremely impressive failure. Imagine the power it takes to crack a block in half.
glad to see the old secondgen is not going to be scrapped🤗 looking forward to it back one the track
Great channel guys keep up the good work
From Australia 🇦🇺
You guys are seriously awesome. Love hearing you guys talk about building and tuning and racing, super chill and you guys obviously know your stuff. Can't wait to see the rebuild progress!
Thats an incredible amount of boost. I have watched the video 100 times on that engine. It never gets old
All engines pushed hard eventually show up as parts failures, but it's hard to know the limit without testing it!
@@pddofficial 146psi is incredible. When i run 30psi my toes curl lol. 146!!!😬
So, about diesels not rev'ing...
Great that you didn't get hurt, and have the right attitude towards moving on.
So nice to hear Motörhead’s express themselves without expletives. Hammer down!
Exploded? With you guys? No way! Who would think that would happen to you two! Lol!
I am a drag racer i run a 1965 nova with a 406 in it and i have been in your shoes bringing the engin home in a bucket it sucks but that is the price we pay to play right great video guyt thanks have a great night race safe.
No better way to see how things work than when it comes apart.
You guys are the best. Had to show this to my friend
Thank you!
Awesome that you guys do a breakdown on everything nobody else in the diesel industry drops videos like this and explain stuff happy to hear that you guys aren’t giving up on it and you guys are going to read build it can’t wait to see the next video of it starting to go back together👍👍👍
Hey guys look forward to seeing you back on the track in just building my 1st 12 valve race engine and I will be putting in a mechanical air shut off thanks for test piloting for all of us!!
Those were some immense pressures before it blew
Todd has the perfect calm temperament for being a professional driver.
I have a feeling your channel is about to blow up too! Subscribed
Jeez, that's insane... Those rods are why I keep a small piece of plywood with me when starting an old diesel, because if I have to run grab something to stop it with, I ain't coming back!
Good job on your diagnosis. I'm glad no one was hurt.
I think the deciding factor was the butterfly valve failure. That just sucks. I applaud your choice of a mechanical replacement operated by a cable. That would have averted this whole catastrophe.
Glad you were safe. Hope you get it all figured out and it goes better. Thanks for helping us understand what happened.
The freeze plugs look reusable. 🤷🏻♂️
Thanks guys for once again a very interesting video. I've been a mechanic on a prostock tractorpulling team for a couple of years, we have a head full of knowledge, a cabinet full prizes, and a workshop full of damaged parts.
PowerDrivenDiesel kinda we had our fair share of broken blocks, cranks and bearing problems. Our biggest problem is we aren't allowed to use different castings. So block, head and crank are the weakest points. Still we push about 2500hp from a 510ci International with a single 4.8" hypermax Turbo.
Absolutely amazing carnage! Glad you weren't hurt in the process. Thank you for sharing this, I really appreciated it
Truck passes the eighth mile! Truck says, Oh No, Dude! You wanted POWER! Well here it is! Hang on!!
Michael Cuff this made me laugh
Great to see you laughing a smiling about it👍🏻 great channel
"we're gonna rebuild this motor"..... All 8 pieces of it ??!!!!! had me going there for a minute guys !!!!
Glad you guys posted this. Was interesting on why the RPMs went so high.
Don't you guys have custom billet blocks for those things? 30,000psi is getting close to rifle pressure levels! Crazy!
Todd knows how to kill a Cummins for sure, with him it’s never a small catastrophe seems the engine always jumps out of the hood
You guys are the hands down realest in the business. Keep doing it.
Just as enjoyable to watch you guys dealing with failure as you do with success. My only fear was that you would throw in the towel...no way! Hope to see your building vids soon!
Also thinking about the emergency shut down procedure. what about adding CO2 as a last defense. or will that not work at that rpm? I've got no idea. I just know it'll stop a diesel damn quick
How much weight would redundant fuel shut offs be? I.e electric and mechanically actuated valves
once bitten by the Racing Bug no Man Can Say No!! So Good to see you Smiling and however expensive it may be sharing with Us!!!! now I'll enjoy the rest of your story!! I Concur!! I couldn't have passed up the opportunity! only 2 min. into show?
Really glad the truck will be saved, this truck has so much potential its unreal, it just has to come together right, which I believe will happen. Thanks for the videos guys.
Did ya'll ever find out what caused it to continue fueling which required the attempted emergency shutdown in the first place?
This would be the true failure analysis. Everything else was the result of the prime failure. Unfortunately, I suspect with this amount of damage it may be impossible to identify.
I KNOW WITH MY TRUCK TUNED UP A HEAVY REV IT WILL STICK FOR 4TO 8 SECONDS . MAKES ME NERVOUS PARKED. THANK GOD YOUR OK...
Great analysis and insight on what to do and not to do. Nothing I mean NOTHING goes good when you're in a hurry. Good luck guys and will be looking for the rebuilt truck
I guess you could say that block had a pretty good bang for your buck
158psi of boost?? That's insane!!!
That'll buff out! You guys always set a good example for the sport.
Really excited to see what the future brings! I'm glad you guys are keeping a positive attitude!
Glad I found your guys channel. Love the video, it’s helpful hearing how you guys handle these situations
I work for a marine diesel engine company and we use manual air shutdowns on are engines and they work fantastic
That is INSANE! Goes to show what kind of force can be made from a relatively small engine now days.
I loved this show. Best one yet. Thanks for all your insights on doubling the HP. Sorry it blew and glad you are in good health. It happens.
At least you didn't get hurt
Not drag racing related but I want one of the pacbrake or amot valves that shuts the air intake to stop a possible engine runaway situation. Always good to plan for things to fail - murphy always shows up.
8200 RPM has to be some kind of record for these engines. You have to spend some money to get a SB Chevy spin that fast.
Glad your okay and here to tell the story. And how much for a chunk of that block I gotta have a souvenir from this... It just so violent
For the record, at 8500 rpm a stock 6.7 cummins 4.88 in stroke means the average piston speed is about almost 7000 fpm, about half again higher then a Formula 1 engine at 18,000rpm (round 4800 fpm). Considering the piston in a cummins probably weighs several times what one does in an F1 engine the forces that engine was subject to before she died would have been incredible.
Cool video guys, I like how in-depth you went with your analysis. Picked up a new sub!
Man I would love to have one of those pistons for a paper weight desk ornament at work! Great video as usual guys!!!
I remember watching this when the video first came out, but Man is that impressive. Bring her back
Great video, shame about the blow up. A 7/16th bolt in MP35N (alloy) age hardened is the best I have come across, would give at least 34,000lbs tensile strength per bolt.
You may not like the cost, but they are really good!
Wow !! Glade you’re ok. Can’t wait to see the new build.
Make sure the close off valve is hand-pressure operated and not spring operated, and that the hand pressure can overcome the manifold pressure at the errant boost pressures in question. It doesn't need to kill the engine completely - it just needs to severely cripple it until it uses all the fuel in the line after the fuel cutoff. It is possible just a manifold boost pressure dump would be adequate.
Yes indeed. It may be safer to just dump (most of) the boost pressure - at least this can be done reliably. I'm sure a hung rack with little or no boost would be a non-event. Even a stick of gelignite taped to the turbocharger would be safer that what happened to you.. :) Thanks for the really great post mortem, that's pretty cool. Glad you were ok.
That's an epic failure.. Parts can be replaced, people not so much. Glad your ok.. Looking forward to your next truck!!!
Build it bigger, better, stronger!!!!!! You guys will persevere!!
You all seem like great guys. Makes me want to get into diesel work instead of being a millwright
You should put a ball valve on the fuel feed line So you Can cut the fuel If fuelrack got stuck again
Its not a good idea to route fuel line though The cabin in case of fire ya know.
@@joachimsingh2929 i mean somekind of remote controlled valve, like i have cable oprated ball valve in my build.
Awesome update video and can’t wait to see the truck go back together, could you guys do update videos while you fix it?!
What a great video! Can't believe it spun to over 8k rpm
The best thing is that no one is hurt. Hopefully the same will newer happen again.
This sounds ignorant, but what size is this engine? You guys are really smart!
I blew up a Chevy smallblock one time, #7 rod bearing spun, cap blew off and out thru the oil pan, rod caught in the cylinder wall, crank hit rod, rod came out thru the side of the block, boom. No fire, just a boom, and a big boof of smoke, and everything seized up. I pushed the clutch in and coasted a few feet, let it back out and left some more rubber on the road, pushed it back in and coasted onto the shoulder. It wasn't pretty, but it could've been worse. I spun a main bearing in a Buick V6 one time. I had a camshaft snap clean in half on a Ford V10. I never blew up a diesel.
It’s nice to see you guys will take time out of your day to discuss the setback and future plans to us viewers
I really like the explanation of what went wrong and why...
Very nice thank you and I wish you all luck but would like to see more of the ugly truck.?
Thanks again
Im just SO glad nobody was hurt! Because things could of went REALLY bad!
us as well!!
A 6V92 Detroit ran away on me. I pulled the mechanical emergency shut down cable and it sucked all of the gaskets in between turbo and blower and kept on running. Luckily it was on a test stand and the valve cover could be removed and the injector rack controlled by the way of vice grips. The governor failed.
Those detroits sure can be demonic sometimes. XD
Whoa! Yeah, them Detroits only take 1 injector to run the whole thing away! (or a governor!)
I had a Detroit run away on a boat because the shutoff was rusted. When it popped it ripped the motor bed up causing a gash in the bottom to sink the boat.
@Milton Keenes 4 strokes can runaway too. It's not just 2 stroke diesels.
@Milton Keenes emissions are the reason why they make 4 strokes BTW.
Todd, have you ever considered building a 2 cycle Detroit Diesel?..... like the 6V53 (318 ci). Also, I've never seen or heard of anyone build a Cat diesel for the drags (in a pickup or "rail"..... but, possibly because the Cats internal mass is generally heavier than a Cummins of like displacement. I would really like to see someone build a 2 cycle Detroit for the drags. The White Lightening RED (Rear Engine Dragster) that John Carey was running back in the late 1970's was running 7.20's way back then, and it was De-stroked from 318ci down to 270ci and was putting 1,000hp to the ground, Before he "put it on the bottle"!!.... also had a near perfectly "clean" exhaust as well!
The only reason he quit campaigning it was because it was breaking too many drive-line parts, more so than his Two Top Fuelers were that he was also running.... and it was running all top fuel parts in the driveline. John told me that when the turbos would fully spool up when he "hit the bottle" about 40/50ft out of the hole, that the power (torque) would come "on" so fast and hard "that it was like getting rammed from behind with a huge hydraulic ram, and it would snap drive-line parts like pretzels"!! so, parked it and just ran his two fuelers.
As far as I know (at least, he did just a few years ago), he still has the White Lightning (complete, just as he parked it)... it's sitting up on the 2nd stage of one of his big storage shelves in one of his shops with about an 1" of dust on it... he builds marine diesels on the east coast, has one shop in Maryland and one in Delaware.
PS: He never blew the engine up in the nearly 4 seasons that he ran it.... just Lots of drive-line breakage, of course with "today's" metallurgy, that would probably no longer be an issue with his 2 cycle dragster.
Go get it boys. This is inspirational to every diesel owner who has a failure and feels like they're in the gutter spitting out teeth, rods, and blood. Go show em it ain't shit and you'll be back and better than ever!
Glad you are OK, RIP another race track.
Swear I heard that boom from my house lol. Glad you got out safe. Sooo bummed that RMR is shutting down. Now my racecars are for sale
typical hot rodders... great stuff guys... Keep on having fun and learning..
Well, you definitely went out with a bang. You will be more popular and remembered by this moment!. Maybe open a domain called "The guy's that blew their shit up at the 1/4 mile .com". That sure sucks that happened but glad your safe! Thanks for keeping it real, keep the informative vid's coming.
