The wheels are off the ground. There’s zero load/ resistance to prevent that.
There’s another video a month or so ago of guys doing the same thing but on a road and it explodes because the guy with the NOS bottle hits it while the driver is shifting so there is again no load on the engine and it can instantly spin too fast and destroy itself
Just so that I get this right, the reason that the engine blows up is because of the lack of resistance on the wheels, right? So the energy has nowhere to go? Do I get that right?
Think about it this way: you’re sitting in a car and it’s stationary and you push the gas pedal all the way down. What happens? You accelerate forward and the RPMs climb as you move.
Now what would happen if you were sitting in the stationary car, put it in neutral, and then floored the gas again? The RPMs would redline almost immediately because you’re not driving the car, it’s not having to move the whole vehicle. It instantly redlines.
I was a bit confused by the phrase "the engine isn't under any load", but indeed this makes sense; there's no friction, so all the energy goes into increasing RPMs rather than moving the vehicle.
Just out of curiosity, what part of the engine cycle is actually detonating here? Is it too much pressure in the cylinders because of the repeated ignition of the gas? (I also have a very basic understanding of engines)
That’s where my knowledge gets thin too but the engine is rotating WAY faster than it can handle and rapidly dismantles itself. Could be over pressure, could be broken rods launching pieces through the engine walls, etc. I can’t say for sure but maybe someone else can
So the drivetrain on 4cyl engine looks like this ^ the pistons fire in sequence fist 1 and 3 then 2 and 4. This sends power to the transmission. When in neutral none of the gears in the trans are aligned with the drive train. This causes the drive train to redline. Add in NOS and the drivetrain overstresses and bends now when the fuel ignites the pistons won't move and BOOM! You have successfully turned your engine into slag.
On the contrary, I would like to confirm my understanding. Nothing wrong with asking "stupid" questions. Also, I only just realized that NOS stands for nitro, which makes infinitely more sense.
Could the same thing be achieved by just putting the car in neutral and mashing the gas? Because if they had it in drive wouldn’t the wheels still move like on those Dyno machines?
Not quite like on a dyno, since you still have the weight of the car on the wheels to push on the dyno. And while the engine won't have to deal with moving the car, it will have to deal with spinning the dyno under the weight of the car. Not quite the same as actually driving of course, and accidents on dynos do happen. but it's not nearly as dangerous as this.
Appreciate the explanation, I have some questions though:
Are the wheels really off the ground? The way the tires move at first but then stop makes it seem like there is still some load. So they only lifted it up partially? Why even, whats their goal here?
How come rally car engines don't explode when they get some airtime? Or driftcars? Is that just because they have a rev limiter?
They probably injected "nitro" (that gas tank in between his legs) in to achieve better motor performance. If you give too much or don't regulate it properly, instead of running faster, the engine decides to grenade itself. The forklift was there to stop the car from driving away, probably a poor mans dyno test. (Feel free to correct me if i'm wrong)

As soon as you see it’s on a forklift like that you know what’s going to happen.
Haha yep
Wait why? And what actually happened?
The engine isn’t under any load so it’s going to instantly redline and explode
What does that have to do with a forklift?

Now add NOS
Thanks for the great explanation!

Are you ten years old? What is complicated about this?

I'm not big into cars.
Thank you for explaining that.

Yes

Yes on the putting it in neutral part.

It actually blew up
Fair enough
"This is as safe as it gets." Meanwhile, he is hand releasing, not a gage in sight.
You don’t need a gauge if you’re trying to blow it up.
They wouldn’t forklift this if they weren’t trying to blow it up.
My ears bleed just from watching this
Dang bro you should get to the nearest ER
WHAT?
HE SAID THAT BRO SHOULD GO TO THE NEAREST ER.
YOU SHOULD PROBABLY JOIN HIM.
It blew up
He has not been doing this for a long time
And now he has zero credibility forever lol
Danger to manifold.
I'm so confused. What happened? Why was there a forklift there? What was in his hands?

Ah, I see. Thanks
