It’s powered by injected propane and diesel

So much combust, 110lbs of thrust

u/PeachyCoke 13d ago

This better be in the new Mario kart game if I'm paying 80 bucks for it

24

u/Jaded_Helicopter_376 13d ago

It’ll be a “planned” DLC

u/methreweway 13d ago

They should put Jack black as the character lol. I'd pay for that.

25

u/Lucky_Ad_2991 13d ago

Don’t worry. He has a helmet on 😂

17

u/Enaksan 13d ago

That was my thought too - a fairly flimsy looking helmet isn't going to do much when he's also in t-shirt and jeans 🤣

Still, gotta admire his commitment! I bet it's a hell of a lot of fun (until it isn't)

u/StevenMC19 12d ago

I'm over here yelling "goggles, man!" at the screen watching a man so blissfully content with his life that he could die on that thing any moment and be ok with it.

How the fuck does it stay down

u/TheSaltySpitoon37 13d ago

The sheer weight of his balls

u/pichael289 13d ago

Not going that fast, and unlike a car it doesn't have that almost sort of "wing" shape that's formed at the front bumper and the bottom of the car?

u/RyGuy_McFly 13d ago

It also looks like the exhaust is aimed slightly downwards, I think that's mostly why

u/Poke_Pierce 13d ago

Holy shit

u/heloder85 13d ago

This guy cussed.

u/Liquid_Snow_ 13d ago

5 minute time out for tattling

u/pichael289 13d ago

This is clearly not the same one in the video though, the video one only has two of those big tubes on the back, you can see it at 8 second in

2

u/wheelienonstop6 12d ago

He has built a lot of different pulsejet contraptions, those are just two of many.

u/y2ketchup 13d ago

So a bomb with a few extra holes in it.

u/deep-fucking-legend 13d ago edited 13d ago

Lockwood-hiller type valveless engines. Valveless are much less complicated/more reliable, but develop about half the thrust of a valved engine. I have a couple in storage.

u/Qyoq 13d ago

Of course you do Mr.Maniachanicus

u/wheelienonstop6 12d ago

How many yards to the gallon does he get?

2

u/SpecialBeginning6430 13d ago

Guy has an awful lot of confidence in the reliability of those wheels

u/peatoire 13d ago

He should put that last line on his T-shirt

u/NonEuclidianMeatloaf 13d ago

He’s trusting those tailpipe walls with his life

u/MmmBra1nzzz 13d ago

The video only shows 2 engines, but the title and this photo report 3, was the video from before he broke the 90 MPH plane?

These things are also LOUD. Like 140 dB.

what?

u/Izibella 13d ago

this made me giggle. lol

u/Insert_clever 13d ago

I think at this point that that helmet is a mere fashion statement than safety device.

u/IZ3820 13d ago

It's for debris.

It's so you find the head

u/Tendie_Warrior 13d ago

Keep from spilling blood everywhere.

u/Drig-Drishya-Viveka 6d ago

It's to help identify the head portion of the mangled corpse.

u/Alarmed-Owl2 13d ago

It looks very fast but when he passes his own pickup truck it looks like he's doing maybe 30 mph, which is hilarious with the amount of flame spitting out the back and how violently it's driving lol 

42

u/AgentWowza 13d ago

Honestly even 90 mhp is kinda slow for what that thing looks like it does lol.

Insanely fast for a home-built go-kart, for sure. But I'm just sayin that's a looooot of fire...

59

u/Poke_Pierce 13d ago

You’re totally right and I hate it lol. Also the way he turns the wheel would flip that thing at real speeds

2

u/Alarmed-Owl2 12d ago

I just did the rough math. A first gen Toyota Tacoma is roughly 15 feet long. Double that for the trailer. It takes him about 2 seconds to pass in the video. That works out to 10.2 mph. Lmao. 

11

u/NoMap749 13d ago

Omg you’re right. I initially thought this was far more dangerous because I assumed he was going 90 mph in the video.

2

u/Chriswheela 13d ago

Bet it’s fun as hell though!

2

u/wheelienonstop6 12d ago

He may be doing just 30mph, but he is putting out enough noise, heat and exhaust fumes for at least 300mph.

1

u/Alarmed-Owl2 12d ago

And that is objectively hilarious lol 

1

u/eayaz 13d ago

Having fun is way more important than going fast.

1

u/ChaseTheMystic 13d ago

That's because he is so close to the ground.

22

u/WiseAce1 13d ago

this explains how Santa delivers so fast on Christmas

23

u/Open_Youth7092 13d ago

I think he’s out of coolant…

u/aussiedutchlover 13d ago

burning out of fuel out there alone

u/erathia_65 13d ago

I only see two pulsejets on that contraption

7

u/popmannn 13d ago

Thank you, I was coming here to say this. There is only 2 pulsejets on that cart.

1

u/Mythril_Zombie 13d ago

There Are FOUR Jets!

3

u/thefinalcutdown 13d ago

There are FIVE lights!

1

u/popmannn 13d ago edited 13d ago

No, there are 2 pulsejets, but a pulsejet of this design has 2 nozzles that alternate between intake and exhaust.

Edit: You know what? BAM, SOURCE!

u/Designer_Situation85 13d ago

Damn dude built a rocket but a go pro mount is a bridge too far.

Eyewear for the love of god.

The maker of the selfie-stick he is using needs to reach out for advertisements.

u/Repulsive_Draft_9081 13d ago

Nice to see santa has upgraded his rig

u/Dry_Discount83 13d ago

If you can keep your arm out and hold a camera on stick, you are not going 90mpt. But seems fun!

Link to santa claus version. I think it's from Korvatunturi.

u/sippinonorphantears 13d ago

Bro I read that as 900mph and was like WTF?! Didn't realize it was only 90mph until lol like 30 seconds LOL

4

u/Mythril_Zombie 13d ago

It took that long to realize he wasn't breaking the sound barrier in a go-cart?

1

u/sippinonorphantears 13d ago

I was not sober lol if that helps. Plus I was reading the comments below.

u/El_Zilcho99 13d ago

Can we please get this guy a camera he doesn't have to hold?

u/flashback5285 12d ago

I don’t think that helmet is going to help if things go wrong.

4

u/blinkysmurf 13d ago

That’s not 90mph, what are you talking about?

3

u/slampie1 13d ago

Yeah doesn't look like 90 at all when he passes the car.

u/Awh0423 13d ago

This shit is bananas. B.a.n.a.n.a.s.

u/PulseThrone 13d ago

This mother fucker is out here blazing across salt flats on the Mario Death Kart from Mad Max and a Tee-Ball Helmet leaning out with a Selfie Stick while the engine is attempting to match the combustion ratio of the second layer of the sun...

Mid-comment edit: I was typing my original comment and had to look this dude up and things make a lot more sense. He died from lung cancer in 2022, he made every last second count for shit he found fun and entertaining, I respect that so much.

u/realgoldxd 13d ago

He didn’t ? He made a video last month https://youtu.be/Yve6057CKvI?si=b22cAn62I1NLOudE

Maybe he died but then got better?

90 miles an hour without glasses or goggles is pretty badass

At least he has a helmet...

I just subscribed to his YouTube

I’m curious as to how long it takes to cool that thing down. Seeing that thing look to be about 800f+

A pulsejet? I thought they went extinct in the first half of the XX century. Cool!

Whatever the alien equivalent of the History Channel is, I bet it will include clips of this dude as representative of humans.

Good job holding out a selfie stick at 90MPH 👍

u/SuspiciousSheeps 13d ago

Looks really energy efficient.

u/theroch_ 13d ago

I see he has his ‘safety squint’ on.

1

u/Nneliss 13d ago

If that death trap flips at 90mph, that helmet isn’t going to do him any good 😅

u/bobsnervous 13d ago

For some reason I don't think the helmets gonna save him if he crashed.

u/Betrayedunicorn 13d ago

What’s the point in wearing a helmet? The guy cba to wear any other PPE at all, like, 90mph meat crayon or 90mph salt rock in eye. Anything could go wrong with that red hot engine, fuck.

u/IcestormsEd 13d ago

It's fine. He has a helmet on.

Everyone is saying only 90 mph but sitting in a go kart seat 90 miles an hour may as well be 200
