Which way do pistons fly out at 10000 revs?

okay so this machine we use to spin wheels up we have nothing but nice things to say about it you would have seen how fast we were able to get a wheel to spin and so we wouldn't want to throw it away just yet no point dismantling it while it works instead we should continue experimenting so what do we got people have sent in a bunch of requests for over there we've got a wonderful lotta engine they never cease to amaze us man now the idea is to remove the cylinder head pluck it from the motor then we connect it to the machine via some sort of adapter so it's going to be mounted right here to this diff and from there we observe the engine with no head in order to learn how fast the pistons fly out at 10 000 rpm something tells me you won't even be able to see them where do you think they're going to fly towards the ceiling or towards the ground we'll see which direction they fly out or perhaps the engine holds up they are pretty well built after all they've got plenty of durability built into them and we'd really love to find out how stout these are for real how much torture they can take all right let's piece all of this together and see what's up let's do this which way do pistons fly out at 10 000 revs translation and voice over by bmi [Music] russian [Music] [Music] so [Music] look at what we've got here fellas now you see instead of a wheel we've got mounted an engine block we've machined a flange for the purpose of getting them mated we did have to do a bit of welding but okay it's not too bad especially considering that this engine block is not long for this world with how many revs we're looking to get it up to i don't think it's getting out of this alive but on the other hand like i already said a lot of motors never cease to amaze it's all about how balanced they are and durable to make sure the oil pump creates enough pressure we've shortened the chain in stock form it is pretty long with it having to drive the camshaft as well but that was an easy task that i'm sure any school kid can tackle now we need to transport this assembly enough talk it's off to the test track okay fellas we've made it out to our favorite spot for doing such experiments now if something does go kablammo if bits start flying in different directions we are surrounded by a sort of natural shelter the branches ought to slow down them projectiles if something were to happen now look here the attack is currently reading 500 revs which seems about right and you can tell cylinder number one is picking up a massive amount of oil oh my goodness anyway so here's what 500 rpm looks like the pistons are like but what'll happen at 10 grand well let's find out does the servo work it does i think it's time for us to move away looking good from there we observe from a distance why from a distance well we've seen flying metal before look at it building revs is that it wow holy cow look at it spewing oil [Music] look at that a toyota engine is spinning up a ladder engine look at that oil fly something just happened [Laughter] [Music] there we go too bad the sound ain't coming through oh right [Music] i think we broke something but what exactly we did get to redline indeed we did let's go have a look hopefully the counter has the results saved oh so much smoke isn't that something oh my it spat all over everything and the gauge shut itself off i can see smoke coming from the diff even look at that can you see it coming from the housing holy cow dude now you'd recall that in the previous video we recorded the maximum rev count which was 10 000. and it was very eager to get there this time around the engine did get to redline you could hear how in fourth gear it was spinning like a madman this lada engine was able to endure 10 000 revs without any hiccups it wasn't strained in the least plus everything seems to be intact the smoke not withstanding that was very much to be expected with how much friction there is the oil gets really hot oh the block is warm as if the engine was running this feels like 55 celsius maybe amazing and that's with all of that lubrication yeah if you consider that we've poured in plenty of oil it's amazing how hot the engine block has gotten with no combustion just friction oh the bulkhead is also hot to the point that my fingers actually hurt that has to be around 60 degrees man so we never started this engine and on top of that it's missing a cylinder head and it's hot okay so we've established that it can keep it together at 10 grand we've fired it up once more and decided to look for weak points and so right now something has to go down there's this tradition around here it's okay so now it's pedaled to the metal and from there we wait until that weak point reveals itself until it makes it to the surface [Music] [Music] amazing what a noise that's a lot of ribs [Music] and still climbing [Music] that's it we're at full tilt [Music] seriously though we're out of gas oh no okay so looks like we're experiencing our first malfunction so the pistons are sometimes convulsing while the adapter is rotating non-stop and there they go again so the crankshaft has a tab for which we carved out a perfectly matching slot so that's all done properly however look at that it's working something is wrong in there seems like we have a battle going on but who's winning i suggest we head back to our facility take all of this apart and have a look inside to see what happens allow me to demonstrate the weak point of the setup so we attach a pulley to the crankshaft right here so yeah we've got that pulley on there it's the one that spins the water pump via belt the alternator as well as for what happened well here we used to have a tab and that tab has been sheared off the thread for the nut has also been destroyed see how thrashed this area is and so that's we do have a more substantial joint on the other side that's where the flywheel is at and so that's what we'll be attaching to the [Music] machine [Music] then [Music] do [Music] okay fellas here is what we were able to cook up i still haven't gone into any sort of detail so you would have seen us extracting the pistons and all for the purpose of well with everything being in stock four this engine which is far from new has had a pretty rough life we weren't even able to scratch the cylinders by the way granted it was spitting a bunch of oil which is no surprise given a complete lack of well at seals we saw how it spews oil when there aren't any anyway so we took everything apart mounted it backwards the mounting solution is more durable this time around let me remind you that we lost the tab from the crankshaft we actually had to weld this pulley back on then we marked it so that the tech can get a reading now i expect it to work this time given it'll be placed separately and the vibrations shouldn't be too crazy now since the engine and stock form refused to disintegrate we've made incisions on the rods in cylinders one and four the in-cylinder number two the rod is a bit loose as in we didn't tighten it in cylinder three we ground down the cap and we tightened it down with plenty of force something is bound to happen any way you cut it this time around it's modified to spin until it explodes i don't know with pistons flying to outer space well that's the sort of thing i expect is going to happen all right we've got everything mounted we've rolled it off the trailer to get rid of any vibration so it's time to start it run away and take it to redline and then we see what happens run [Music] it's all right now we run for it are we doing this [Music] sure it threw a piston we need to go shut it down [Music] [Applause] [Music] [Applause] [Music] [Music] [Applause] [Music] now we have to quickly [Music] we did it guys so here's where we're at with this the rod in cylinder number one has fallen apart we made quite the incision on this one and so it fell apart no it's pretty hot this right here is the upper part it's also destroyed and this is a piece of block it was hit by the rod and a big chunk came flying off so that's about it the piston evacuated of course it did this sort of move and went flying in that direction it didn't get too high though it's a good thing we were able to get everything out since we still have three more in there one of them is cut the other pinched the third loose we need to do i think we should go the knocking has gotten louder [Applause] that didn't take long here's what happened fellas it's all looking pretty good so cylinder number three is seized we've got another hole in the block apparently the rod is seriously twisted let me remind you that cylinder number three is where we had it loose you should always use a torque wrench when assembling motors follows this is one of those things where you need to get everything right too much torque or not enough on the cap can bear certain consequences this is an example of what will happen when there is not enough torque the one in number two was tightened too hard but that didn't turn out to be as big of a problem the main problem now is that the engine is seized up it didn't even go up to that high of a rev count the tech is currently showing us 2130 revolutions we were basically just getting started and that's when things came apart the engine seized up everything was spinning up nicely until a point but then it came to an abrupt stop and in between it and the differential something has been sheared off i mean yeah the block was going to be butchered but the diff we were hoping would carry on for a bit that is what it curious to remove the oil pan and see what happened down there so now i suggest we place everything back onto our trailer head back home dismantle the whole lot and have a closer look at the aftermath of a loose bolt or nut situation [Music] and here we are take a look at this this is pretty hilarious now one of them nuts we haven't been able to unscrew it i guess the thread is boned the other one is just gone and that's because the bolt has been torn apart here it is well a piece of it anyway the rod completely detached from the crankshaft and the engine is now completely seized so what's my overall assessment of the situation so here the nuts were loose here we had a slight correction a few severe incisions those conrods were torn apart the logical thing to take away from this would be that the nuts and bolts inside an engine need to be tightened down to spec like it says in the repair manual and using a torque wrench to get everything bang on and to avoid a situation when you've got stuff falling apart i'd say we're looking at a 107 success rate here we still got the machine for spinning stuff up we wanted to see how the pistons would reciprocate on an engine with no cylinder head attached and well you saw what'll happen at 10 000 revolutions you literally can't even see them they're moving way too fast too fast for the human eye to register and that howling noise we heard man hopefully the audio recording does justice to it what other conclusions can we draw here well the block crank and pistons are designed to take some punishment we spun up that whole assembly and learned that you can actually get them up to eight grand these lotto motors at the end of the day it's even quite capable of spinning at 10 000. these engines are extremely durable and that's all i have for you fellows you saw it all for yourselves let us know what else we can spin up i mean while we still have the machine up and running we have to use it to spin up to the point where it gets destroyed so keep those suggestions coming guys and that's all i have for you if you like this baseball cap hit the link down
