See Through Engine on NITROMETHANE – Blow Up Attempts 1 -9 Crazy !


Welcome back to this episode that I am very
excited about. And that is blowing up the see-through engine. Now in a previous episode. I had A viewer request. To run this see-through engine on nitromethane. Which I did not do because I thought it was
way too dangerous. But I am going to run it on nitromethane in
this episode. I think it’s going to blow this thing apart. But in order to do that. I need to make it fully remote controlled. That’s going to allow us to get a nice safe
distance away. That way this thing can blow up completely. No Holds Barred. That being said let’s Let It Rip. Hear that we are all set. We’re all set we’re ready to go. A lot of people ask me what can go wrong. I guess the whole thing can blow up. Or we get a crankshaft out of the side of
the crankcase. Or the head blows up and pieces fly everywhere. My prediction is that the heat is going to
heat up this plexiglass. To the point where it just goes boom and Pops. For people wondering how we can relate this. This engine is used in the car that you drive
everyday. It’s something that we have been using for
transportation for more than a hundred years. This is the entire principle behind internal
combustion engines. This particular project. With the fuel that we are using. The nitromethane. That is something that we can find at any
drag strip. Like the funny cars and stuff like that. That they race with the big exhaust and they’re
really loud. Those funny cars burn Top Fuel. So it’s pretty explosive from what I’ve heard. I’ve never run an engine on it. Let’s see what happens. Apparently I have to open up this needle a
lot more. I’m going to open up to where it’s almost
falling out of the carburetor. Here we go try this again. I thought the head failed. But actually the electrode came out. Looks like I have a little problem to solve. And I think I already have a solution. Alright I think we’re good. How much can an engine take. Something is sizzling. Yeah it’s a mixture problem. It just ate up the whole head. Haha look at that. So it looks like it actually ran for about
8 minutes. We got some plastic coming out of the exhaust
right there. And the head is a little bit melted. I think that’s why it shut off. Started leaking compression. So I’m going to come back and do it again. That was kind of unexpected. I didn’t expect it to blow out of the side
like that. It’s all melted together look at this. You can see where all the heat is concentrated. Take this apart. Yeah it looks like it definitely melted this
thing pretty good. All that really happened was. We started leaking compression out of this
little hole. That got melted between the head and the spacer
here. And the burned up this had pretty good. It looks like the plastic was part of the
fuel in this case. Because this whole plastic was getting shot
out of the exhaust. This isn’t what I wanted to happen. I wanted this whole thing to blow up completely. So I think this is the week part right here. This spacer so. I think I’m going to just change this out
with a more hardcore spacer. I have the spacer plate completely 100% done. And I doubt that this one’s going to melt. All I’m going to do now is I’m going to throw
this back together. I have a new acrylic head. That’s not as bad as the one we burned up. This time I have a new spacer. And I also have a new fuel. In the last run I ran RC fuel which is 30%
nitromethane. And as you just saw it did not blow the engine
up. Originally I wanted to run 90/10. 90% nitromethane 10% alcohol which is Top
Fuel. But instead this is what I got. This is 50% Nitro and 50% alcohol. The reason I went with this fuel over the
90/10. Is because the 90/10 takes a lot of spark
energy to fully ignite the mixture. I don’t think that this Magneto has enough
spark energy to do that. And now that I’m going to be running a higher
percentage of nitro. I’m actually going to remove this flywheel. To change the timing. I don’t know what this runs from the factory. But I’m going to do about 30 degrees advanced. That’s pretty modest. I’m thinking where it is now is about 13. That’s 45. That’s 90 right. So right about there that should do it yeah. Normally Top Fuel dragsters from what I know
run 50 to 60 degrees advanced. Because Nitro Burns really slowly. My main goal here is I want to make huge explosions. And get as much power possible out of the
Nitro. This is the nitromethane right here. And it smells like acid. But I’ll tell you it does bring back memories. Those remote control cars and remote control
planes. What happened. Since I set the timing so Advanced. We’re going to run the engine here. Make sure I don’t need any more timing adjustments. Then we’re going to run it and blow it up. Since I’m burning more of a percentage of
nitromethane. We need a lot more fuel. So instead of putting a bigger jet. I raise the gas tank to a higher level. That’s going to give me more fuel pressure. And increase the amount of fuel. Hopefully. After running it for a few minutes. I found it really interesting that it idles
like this. Look at how it’s idling look. I thought that was pretty crazy how it idles. Really really low and quiet. And then when you rev it up and goes crazy
watch. Alright looks like I have a new problem. I went to start this engine up again after
that last run. And apparently. The nitromethane is wreaking havoc on our
carburetor. Because we now have no more fuel. It looks like I found the problem here. If you look at this float. This float is actually supposed to be level. The float is kind of stock. And there’s our little needle. It doesn’t seem like it’s clogged or anything. There’s definitely not a o-ring in there. The little tip of that is rubber. I guess this expanded with the nitromethane. So maybe I just need to adjust the float. Let’s get our see-through head on here. So I have two new gaskets. And the new aluminum spacer. This should work out really really nice. I’m going to start it up so we can see how
it looks. Running with the see-through head on nitromethane. Now that I gave you that little demonstration
of nitromethane on the bench. I’ve been searching the internet high and
low. For some type of Clips or animations or something. How nitromethane Burns differently. Compared to gasoline and other fuels. And my search came up empty. So before I blow this up. I’m going to bolt on my last remaining transparent
head. Set up the high speed camera. And I’m going to try to capture some high-speed
footage. To reveal just how differently nitromethane
Burns. Compared to other fuels. Then I’m going to run this thing Full Throttle
and see if I can get it to blow. This is what we got. It started melting up the head a little bit. But at this point I’m hoping that the head
blows off. Or something cool happens. I guess we’ll see here it goes. Let’s do it let’s blow this thing up. Whoa that’s all we needed was a little Spark. There it goes Full throttle. Hold it hold it we got oil. Got oil coming out. The engine is kind of still running. We got oil flying out from all over the crankcase. And from the Magneto over here. I’m not really sure what’s happening. I’m going to try to start it up one more time. And see if we can get it to blow. Do Full Throttle again. It kind of died on its own I don’t know why. But there’s oil all over the place. I’m going to start it up one more time and
let’s try to blow it. Here it goes. Here goes my second attempt to blow up our
Briggs & Stratton a nitromethane. Oh it still runs. Here it goes Full Throttle. Oh hold on it’s still running it’s still running. Alright I don’t know what happened. It doesn’t want to run anymore. This is our second run and I don’t know what’s
going on. But there’s oil everywhere as you can see. I don’t know where that’s coming from. It’s all over the ground down there. I can’t see where. But we’re like leaking compression or something
somewhere. But it still runs. I don’t know in like died out on its own. I don’t know what happened if it’s like overheating
or what’s going on. This is going to be my 3rd attempt. I’m going to try to start it up again. And see if it starts. And I think this is going to be our last run. Because I think it’s on its last leg. Or last piston. I mean the head looks pretty beat up there. As you can see. Yeah I’m surprised it’s holding together. I mean it was Full Throttle. It was definitely more than 3,500 RPM. Start this baby up we got oil all over the
place. Look at this we got oil everywhere. I’m excited. Alright so that was definitely a head failure
there. And that’s what it looks like in your car
when a head gasket blows out. Okay I mean the Briggs & Stratton held together. Surprisingly enough. After all this abuse. The Briggs & Stratton is still holding together. I can’t believe it. Take a look down at the engine here. This was our third attempt at blowing this
up in this episode. We got oil coming out of the crankcase I don’t
know what’s happening here. I’m going to have to investigate further. What did every subsequent run. More and more oil is coming out of the crankcase
somewhere. But ultimately. The mechanics of the engine seem to have held
together. Maybe the crankcase is leaking oil somewhere. But the mechanics themselves have held together. Our failure at this point was the head gasket. oh shoot oh that’s hot. That’s hot. So anyway it wasn’t even our had that failed. It was the head gasket that actually blew
out. As you saw on the high-speed footage. I wanted to get something cool with this engine. I wanted it to just blow up. But I think that was cool enough for now. The next step at this point for me. Is to move on it to the next step in the story. I’m going to get the turbo charger. Both it on here. And I’m just going to do it one level up. I’m going to do the turbo. And the nitromethane and 40 degrees timing. And full throttle. To see if we can actually get this thing to
fail. All I can tell you this much. If I had a company making lawn mowers. I would definitely buy Briggs & Stratton. Let’s take a look at all the oil one last
time. And you can see how much weight we needed
to hold this thing down. I mean this is a beast. Is 100 lb is 140 lb and this is about 100
pounds. That being said that’s how much weight we
needed to chain this Beast to the ground. And I’m happy. I think this looks fantastic.. Hopefully you enjoyed that episode. This was a long one. We had a lot of attempts to blow this thing
up. That were unsuccessful. Subscribe if you like this kind of stuff. And that’s about it. See you in the next video adios.

  1. I wonder if the Briggs company will see this and use it for their commercials to show just how strong their little engines are! Hey it's all about reliability!

  2. Just a suggestion: This run should be done AT NIGHT, or in the dark, so the combustion is clearly visible.

  3. wait, it is not blowing up because of the nitro. Any engine would die on any fuel if you raced it to those RPMs under zero load !! You are asking the engine to absorb all of that power.

  4. There's nothing more frustrating than an engine that refuses to explode. I mean, who designs these things, a room full of monkeys?

  5. could you do a test with varied 'spark screw' location to check power? You could have 8 screws with 8 wires and switch between them to see how the flame front propagates, engine power, and hot spots etc?

  6. Ads IN THE MIDDLE of videos sux ass. Left after the SECOND 5 second dum ass o reiley ad.. Be damned if im gona let some suck as ad eat up my banbdwith that im paying for. I know u need to make some scratch but dam.

  7. CH3No2 has a air/fuel of around 2.5:1!! We burn it about 1:1 with air. To properly test you engine you need around 13-15:1 static comp ratio if you run 1 spark plug you need to fire it at least 65-70 degrees before TDC. Are you using hobby 20% nitro? I happen to have some clear china 100% . I really cool science experiment is to see how much nitro thermally expands. It’s got to be 15-20%

  8. Blowing oil due to crankcase pressure from ring blow by. Have to evacuate the crankcase pressure. Try a Lexan Glass laminate glass to cyl. Set up a set of pressure gauges to read case pressure as running. Move ignition point to center edge of the cylinder just off the valve area.

  9. thi guys an idiot what did he think would happen nitro burns way hotter so it is going to melt plastic in no time before the engine blows so get real.

  10. You look a little bit like the aliens in Prometheus. If they were half as smart as you they wouldn't have ended up extinct. You've earned a lot of respect from your videos. Thanks for sharing.

  11. You shoukd explain the dangers of breathing the fumes from nitromethaine and what it causes before some kid gets hurt

  12. New sub here, your channel is great! This video just shows how durable and reliable Briggs and Stratton engines are, amazing! I love Briggs and Stratton engines!

  13. With a Briggs when u turn them that hard they push oil out the back cover where valve springs are located that’s where all the oil coming from

  14. Any one else notice how the engine switches between two stroke and four stroke i don't know much about Engines but that does not sound like a good thing

  15. Just like a drag car… you need a puke tank… and it's normal for the oil to look like iced coffee after a run.
    Great vid man.

  16. That’s some serious crankcase pressure going on there lol. Talk about bulletproof, how on earth is that little engine still running ???….. Amazing 👌👌👌

  17. I'm searching about hydrogen and how it will work engines but I have few equipment so please try hydrogen and let's see how will burn I really need respond from you cuz no one is honest like you

  18. Poor rings couldn't seal the compression enough thus allowing compression into the crankcase and blowing oil through the breather vent and the oil seals. Cool video!

  19. When i was around 16 years old i put just a cap full of rc nitromethane in about a half a gallon gas tank on my go cart. Thing sounded badass for about a minute until the little connecting rod shot through the side of the block lol

  20. If ya want to blow it up Use Nitrous Oxide a 100 Shot Dry Nitrous or diréct port maybe convert the motor to direct Fuel Injection

  21. You're never gonna get it to blow while using the see-thru head. It will continue to lose compression before it can blow.

  22. Ever since i saw your first video i could swear i saw you on tv like history channel or discovery or science channel or somethin… have you been on one of those channels

  23. The fuel makes a lot of pressure being that this engine wasn’t designed for it when your make a strong spacer the oil leakage was the next weak point

  24. 50/50 nitro/alcohol has a stoich ratio of like 3.7:1 meaning to actually make the extra insane power, you would have to rejet the carb on that engine to burn WAYYYYYYYYYYY more fuel.

  25. Bro did u really use a crayon/wax chalk to trace that template? Instead of having a 1/4" line when using crayons against an edge, try a scribe if you want a much more accurate and controlled template/layout line.
