I respect how you kept running it after the explosion and copious smoke. A noob would have shut it down right away, not realizing that in many cases, like 65% or more, these problems self-resolve with the application of just a little more throttle.
Yes, many's the time I've seen the engine heal its own crankcase from the inside, retrieve its piston from the dyno floor and fit it back on the little end of the twisted conrod, all while at 4000rpm on half throttle. Occasionally, I've seen really good engines refill themselves with Castrol 10W60 racing oil, but that was only a few times. Those "noobs" don't know anything!!!
I saw a guy blow up a naturally aspirated big block in a roadster one night at our local drag strip. It spit two rods out of the block and knocked holes in the block on both sides. He drove it back to the pit area and you could see the crank rotating and it was running fine on 6 cylinders. Probably had zero oil pressure.
@@donziperk The other cylinder head, valves, rockers, pushrods, lifters, and maybe some pistons and rods from the cylinders that didn't blow up could be saved
Id love to see what things looked like as its being torn down, the failed parts and collateral damage. Had a 800cc 2 stroke that had a new Wiseco piston seperate at the pin on the first WOT pull. Destroyed the engine, rod mauled the cylinder and cases.
No Steve’s explosion was a result of brittle rods with way more power than could take. I highly doubt that happened here he was also making 4,500 hp when they broke
@@cameronboan627 Yes, those rods looked like shattered glass. Never should been made that way. Aluminum should bend and break, not shatter like glass. Could have been the fact that those rods were anodized, which creates a hard layer. Also, maybe the type of aluminum they used work hardened too fast, too short of the useable lifespan of comparable aluminum rods.
With a magneto ignition, you shut down engine by cutting fuel, which he did. Grounding out magneto is not a reliable way to shut off the engine, it may continue to run, a.k.a. diesel,
@@quicksilver462 Even then you should have that connected to a remote controlled solenoid that can be shut off outside of the dino room in the control room. Watch engine power on power nation ordination to see what a professional Dino looks like.
When I worked in a major brand diesel shop in the early 70’s our engine dyno room had no shut off to the electric fuel pump. You walked all around the engine under load as it was being tested. On the exhaust/ turbo side, it was very close to the wall, you had to squeeze by checking for oil and coolant leaks around the heads etc. The only way to shut the engine down was by manually back off the fuel pump solenoid. That took a few turns. Once when I was running in the engine at progressive load levels, the drive shaft failed, and was banging around in the safety tunnel. It was an old waterwheel balance beam unit. I was quite frazzled, as in I thought my sex drive just fell off. I shut down the engine, and then the city water supply that loaded, and cooled the waterwheel. After reinstalling another shaft, ( we kept spares ) I fired up the engine again, as I increased the RPM, I watched in horror the large diameter water hose connection expand like a ballon ! It burst and a geyser of hot water hit the ceiling and gave me a hot shower. I had enough for the day. Good time to clean the tools. We had a larger dyno on the other side of the room that could handle the 1710 series V-12’s.
I haven't read but I'm guessing lean on fuel because I was wondering why it built RPM and power and sound at very partial throttle but once it was opened up it seemed to fall flat I didn't even know there was going to be a failure so it sounded like it just didn't make power after a point that should have been noticed because I noticed it. For all I knew the failure was at redline or after throttle down but I was confused why it fell flat once the throttles were part quarter open
THAT is supposed to be1,500hp? I'll let you try to spread that bull.take 500 off on account of the lack of a properly setup dyno machine. If you want to see a well setup dyno, look at Steve brule, and the dyno he operates. This one is just horrible. It's not bad, it's worse than bad. Never have the shut off switch ON the engine! That's how someone could be injured, and if the engine were on fire, you couldn't stop the damned thing, and that could kill someone! Etc were they thinking?
Yeah some of these guys like to tune shit right on the brink of destruction, Trying to extract every last little bit a horse power at red line. Timing wasn't quite right and probably ran way too lean.
Let me get this straight: the manually operated shut-off switch for the experiment is one inch away from the ridiculously high RPM belt on the front of the engine? Wise, very wise.
trust me that worry never goes away. ive built quite a few small engines over the years and car engines too. every single first fire is nerve wracking. and every hard run is the same thing. yeah i know ive never had a catastrophic failure on an engine ive built that was due to me. but every part i used has human error smeared all over it and could be the potential cause of a new window in a block or cylinder. or could be my first big mistake. hell one of my last builds was a 2 stroke that has held together for over 30k miles. the cylinder has changed 2-3 times due to goals changing but that thing has went over 10k miles in a cylinder too. every noise it made was pucker factor lol. sooner or later you just expect them to fail and then every drive is a pleasure cause you always make it home. the last small block i built i now worry about the transmission grenading or the rear end every time i hit the gas but it used to be the motor. it owes me nothing at this point but i dont wanna lose it and i cant keep my foot outta the gas.
you are only able to push iron steel or aluminum until it reaches the max. you can only push it so hard until it reaches critical failure. thats why you dont do that to a 1500hp engine. it might seem like its strong enough to handle that kind of power but it really isnt
It's like a _Wyle E. Peyote_ episode, where he dialed in his A.C.M.E. rocket too lean for prime time. Before you can keep up, you've got catch up. 😶 Fortunately, no _HEMIs_ were harmed in this demonstration.
Hanging pistons on the con rod backwards will do that. Bad habits are hard to break. Breaking hardparts is easy. _"Stronger parts will ficks it!"_ _"Next time, let's put the side of the block on the shock tower. Shall we? Now That's Power !!!"_
Engines don't just blow up for no reason, or without any warning. An expensive engine like this, hooked up to a dyno and being monitored every millisecond, would absolutely have thrown up a red flag moments before catastrophic failure. So, what happened? Did the guy on the laptop just _forget_ to set safe shutdown limits while they adjust the fueling, or did he fall asleep and ignore the gauges going wild? Either way, I think someone just got his ass kicked by a furious engine owner.
Seems to me she chucked a head gasket because it sounded like all 8 and just white smoke, cylinder failure is usually blue and noisy and missy if the ol girl popped a piston. just my opinion
Yea because people are putting ford engines in everything. There's a reason people are putting ls swaps in everything, because they're reliable. Haven't seen many ford engines in anything but fords. Maybe because they're garbage, idk.
Did this engine belong to the shop? Maybe that's why there didn't seem a rush to shut it down. On the other hand, I'd hate to be the one breaking the news to a customer.
Why did they even do the test- that thing wasnt right from the get go. Im guessing it was an already hurt engine that they decided to video as a live grenade.
Sure you have Jim I’ve built just about every engine from every manufacturer 3cyl 4cyl 5cyl 6-8-10cyl Turbo Detroit’s Cummins CATs And that means nothing. You haven’t built shit if you have never seen a parts failure. I just love the clowns quick to blame who know it all. Your probably a Brandon supporter who is still wearing a face diaper
