Amazon Drift Quad gets a Turbo! 

Ethan, thank you for giving these young men with special needs these opportunities. Its very admirable to see their carer support them with making decisions on their own.

This entire video starts making alot more sense when you see how much exhaust these guys are inhaling 😂

I love how the underlaying theme of all these swindle builds has become "impress shop dad"

Edwin: "Boeing level of engineering" Yep...

EDIT: Ethan to the rescue at the end luckily. You need a restrictor for that oil feed, oil pouring out the turbo means you're pushing oil past the seals, not good at all!

Tiny single cylinders like this need an air capacitor to make good boost across revs. See the SAE article "A Method for Turbocharging Single-Cylinder, Four-Stroke Engines". For a lot of your guys' projects, there is a lot of overlapping research from Formula SAE projects. They post their findings on their university websites :)

As much as I love Ethan's brilliant engineering and fabricating skills, I have never been so entertained by a Grind Hard video. Really brings me back to the old haggard garage days. Keep it up guys!

7:58 “we have been out in the mud for a little while, and things are getting swindly in here” 😂 Will is just a natural born comedian

I know you asked a poll recently what’s your favorite part of the channel. I would like to update my answer. My favorite part is allowing the guys to grow. start getting their hands dirty and letting their personalities shine. The growth with all of y’all is dope. Thanks keep posting

I just want to thank you guys for putting so much effort and time into your videos, I recently got my dad and two of my younger siblings into watching your content, and though they haven’t watched nearly as long as I have, (I started watching almost four years ago.) they still love it.

Love how Edwin said at 17:00 that they are putting in an oil reservoir to help keep the oil cool. The funny thing is he is using a Yeti water bottle that is known for being extremely insulated, keeping the heat in.

“I’ve just spent my whole life trying to figure out how things work.” Is my most relatable Ethan quote I’ve ever heard.

Will and Edwin's side quests in between Ethan's final boss builds has been such an awesome addition to the channel, and keeps some of that older budget build vibe that a lot of channels leave behind when they start getting lots of money.

What should we turbo next? The NOS tank still hasn't shipped back from getting it filled 😬

Day #1 of asking for an exo car build

“Yoinked by the jank” I’m dying…. 🤣 Edwin and Will are like two little kids… soon as daddy Ethan comes home, the swindliness comes to an end lmao 😜 You guys are great! 👍🤘👏

I love how Ethan always shows up randomly to help or show a lesson to will it kinda reminds me of my dad when I think I know what I’m doing and my dad comes and shows me the right way 😂😂🤘

that massive oil pump you orginally had likely blew the cheap seals out of that turbo

I'm in my fifties but when I grow up I want to be an unhinged, off the wall lunatic just like you guys. In the best possible way of course. Love your videos, your work and your get it done attitudes. ❤

Will and Edwin rocking out in the shop gives me a laugh. when Ethan came back it started working better because it knew it had to or else.

Edwin bringing the heat, as usual, with the music. That slide guitar part was pretty slick

You don't realize how much technical advice Ethan gives these guys when he's lurking in the background until he's not there to supervise...

You could use a bike brake reservoir as an oil header for the turbo save topping up so often

I love this content guys 👍 Pro tip for putting on grips like that - put 4-5 zip ties into the grip so that they stick out the open end, they'll help it slide onto the bars. Once in place you can easily slide the zip ties out and leave the grip in place 👌

you guys are great! I’ve been building and repairing guitars as a hobby for a good few years now but there’s only so many that my son or me can play at once, so I’ve had a change of direction, due to inspiration from you lot! Work bench now has a metal top, there’s welders, plasma cutters and steel benders in the workshop now, and I’m having a blast 😁

I think I learnt a couple of things from this video.... 1- The Swindle Brothers should NEVER be allowed to work in the shop without Ethan supervision. (Ok, I had figured that one out already!) Stephen doesn't count as supervision as he wants to see the Swindle Brothers blowing themselves up as it makes great video content! 😂 2- Through years of working together, the Grind Hard crew have somehow built up a resistance to carbon monoxide poisoning. 🤔 Or they can hold their breath for a REALLY long time!!! 😂

Will is such a great part of this channel. I love seeing him learning through trial and error.

Loved that you opened the door to test the quad, and the wind blew all the smoke back inside!

I love the tiny nos bottle

00:15 - Holy crap! Freddie Mercury is back!

Seeing you guys rip around on that tiny underpowered thing put a smile on my face😂

You guys are nuts, and that's what makes your content Premium! 👍

please make an electric snowmobile crosskart, have the battery stack over track on a servo operated swing arm.. so you can turn without leaning/tilt and do mean wheelies on the rear :D LIKE SO THEY CAN SEE THIS, THIS IS MY MFOKKING DREAM MOBILE, also i wish for this proof of concept so that we can get safer fun rides out in the powder. if this existed some of my old friends would still be here today :/

Watching the boys work without Ethan there makes it feel more on my level 😂😂 otherwise I feel like I'm watching da vinci work and it's just me shutting up taking notes

I enjoy watching these two bringing there creations to life thank you lads your time and dedication is always appreciated🇬🇧🤙

You have a gift of being entertaining just talking to the camera. You are the good content. The rest is a bonus.

Im trying to build a power wheels similar to yours but 72v 3000w im wondering if its a bad idea to not get a steel body and just do a live axil moter battery and seatbelt it would be a dream to get your opinion on this

I am downloading this link ONLY to get my will pushup moneys worth! -You better deliver kid!! :D All I can say is that when Ethan isn't home the crazy cats are dancing on the welding table! I do sometimes miss ethans more serious approach to builds... Carefull all the vids don't evolve into shenanigans chasing views. Stay true to your core!

I really enjoy your content bro, your intention and effort in making this video is really cool🔥🔥

As if there was any doubt, this proves that you two are certifiably NUTS!... and I appreciate you more than ever.

Put the carburettor on the engine and give it the intake manifold from the turbo then it will make a lot of bost

Ethan built a shop and stopped making videos, lol miss his approach

Ok. seriously these videos are so awesome to just sit and chill to. I love what you guys are doing. Seeing the slicks with Track treads had me dying.

love your determination to get it to work

More of a Subaru than a Subaru

Anyone Elle’s know this wasn’t going to work and just skip to the last 10mins

I was actually geeked out by being able to easily look at the stuff on Amazon while you were showing it.

Hey guys! Hey is that a fireman or a policeman or a straight porn mustache. You know I'm talking about. Love you guys.

Sorry, but i liked it way better when it was Ethan building stuff.

Wow!!!! When i was young i used to race mx bikes i had 2 Kx80s, an Rm80, 3 Kx100s and a Rm125, always wanted a set up like you got then it went wrong lol Great Upload

Hahaha I love the sheer joy of these Premium Chang Li projects! Also, super excited to see how the Chang Li turns out!!

Watching these videos kept me out of The streets. Im currently on to bigger and better i have a job now apartment,and car .All i have left is to pay traffic fines to be a productive citizen.I thank yall for these videos that makes me tap into what i really love.wish me well✌️

I look forward to each and every upload. Thankful for Grind Hard

I love seeing y’all do something and then seeing it again in the Timelapse

That oil feed, HOLY HELL! You need barely a dribble, old mate has a fire hose going in and BLASTING past the seals. I love you guys.

yall have came a long way since I started watching super awesome !

"I've just spent my entire life trying to figure out how things work." Yes dude! Thats it!

So glad the algorithm randomly popped you guys up back when you were building Cindy. Grind hard Fridays make me happy.

Perseverance On Pointe good job fellas

Another Great Swindle Bros production !

The new shop is the ultimate playground. Super jealous!

I dunno if it’s something you guys already do but I think there’s definitely money to be made, making “generic” length brackets with the grind hard logo and hexagons in them. For people to use on their own projects. Even just bits of straight with M10/m8 holes people could make their own brackets from with the logo etc

I have been dying to see this one since you guys talked about it on the podcast! So happy to see it at last! I am definitely looking into some merch. I am hyped about the Grind hard movie. Always excited to see what you guys can make!

this has become one of my favorite channels

Can’t wait for the feature film! Great news lads. Will check out the website and see what sort of money you’re asking for. I always looking forward to Saturday morning in the UK as it means there’s another grind hard video to watch!

I've been hanging for this video since you guys talked about it on the podcast

This is golden! You should swap it for the "grom" engine and get some gears, or maybe even something like a 140cc lifan engine. Amazing content guys🙌

Intake pipe sucking closed is a function of the air velocity and restriction at the pipe inlet (the turbo). It oscillates as the intake valve opens, air rushes in, lowering the pressure in the pipe, then the turbo refills the pipe with air as the previous air charge exits the engine. Repeat for each cycle.

Thanks for the video it was awesome cant wait to see how wet nos goes

I love your guises videos you guys are living my dream keep it up 🤘🏻🤘🏻🤘🏻

i enjoy trail and error videos not just so much of someone just running through the whole process as if they got it right the first time W vid

You have to make is as fast as hoomanly possible!, I'm glad it only took half of the video to figure out what I was going to say all along about the turbo, shorten up the pipe to the motor will more than likely work better. You don't have enough power in the engine to push through all of that pipe.

Awesome!! We just did a build on the same frame, they are crazy off and crooked from factory hahah. BTW, I'm pretty sure you're using too much oil, the pressure gets too high and the container is too high up

Instead of a restricter for the oil you could use a PWM ,DC motor controller on the oil pump to regulate the speed of the pump and reduce oil flow. 😊

Yall been going extra hard lately good content

Hey Dudes,, Try a T-piece between the oil pump and the turbo,, feed it back to oil tank, that way oil gets to turbo and excess oil Tees back to tank when oil pressure into turbo is maxed. We used a boat fuel pump on our YZ125 shifter kart with similar principal for fueling. Also diaphragms were being destroyed in pump, so a 8mm hole in vacuum pipe helped save diaphragms by dropping its sucking pressure..

I love this turbo project of yours

YES!!!!! places you can't even walk merch!!! thank you guys!!

😂 thankyou Grindhard for another excellent episode of swindley sketchy goodness!😂 much love from the U.K 🇬🇧❤👍

Balloon the rubber makes the grip go on. Add some dishwashing detergent on the rim of the grip and will make it go on even easier and super grip the grip to the throttle 👌 I learnt this from wake boarding 😎

Plenum volume doesn’t make a hill of beans in a forced induction engine. The rubber pipe was sucking in because the engine was requesting more than the turbo could give. Shortening the plenum volume and hot side only helped you. You need a much bigger turbo. That little thing is giving all it has and the engine is still wheezing. You can clearly tell when the boost gauge never goes to any positive vacuum meaning there is no positive pressure in the plenum even though it’s small enough a turbo the correct size would blow the intake valve open if you disabled the waste gate like you did on the current turbo.

Awesome job gyes can't wait to see it dun great show 🔥

For the intake side to efficiently make boost if you took the cylinder size made a intake plenum that matched that volume with a check valve to hold the air with only having one small cylinder keep in mind the exhaust pulse is happening when the intake valve is closed vice versa leading to a drop in pressure before the intake valve can open. This is a 4 stroke 1 cylinder specific problem. A wonderful example of a well setup turbo 1 cylinder that can show the theory in action would be on Kyle's channel boostedboiz with their turbo shopping kart.

The turbo centre section or (cartridge) is upside down and that’s why it’s blowing so much smoke. Also if you use the oil cooler adapter plate then never use a restrictor in the oil feed to the turbo because then you could be starving oil to the head.

My favourite thing about this channel is the main guys fabrication skills it’s actually impressive. Watching these guys it’s just a comedy channel, not learning anything from them except for what not to do lmao

Use hair spray to put those handle bar grips on. They will slide right on and stay on when they dry. I learned that working at a bicycle shop years ago.

Just like any job, when workers are struggling, all it takes is the boss to show up and fix their problems with a bit of thought, knowledge and experience. Everybody needs an Ethan!

You need a very short exhaust manifold to the turbo and a very tightly sealed waste gate if you want any boost. A short charge pipe isn't a bad idea either, it probably helps the mixture.. 😁

The oiling issue is because the drain isnt flowing enough by circulating it back to the head it doesnt let the turbo drain properly because all the oil ports in the motor are tiny so you create pressure that blows past the seals I had same issue and resolved it by having the drain line as big as possible and as free flow as possible, think of a turbo car and where the turbo drain goes which is usually straight back to the sump with a way bigger line then your feed line.

As a 91 B you can count on the following to be true regarding your M1123 and M1152: Fluid (negligible) Throttle linkage (questionable) brakes (questionable) CV joints (50/50) Rear differential (a grenade in waiting) Inability to hear when going over 55 (100% guarantee)

Will and Edwin have such good energy together.

The Grind HARD Boyz are gonna BOOST Barbie Today! XRX Rated! I'm Pumped Up! 😂😂😂😂

I have just gotten through the intro and I'm glad to see Need for Speed Underground Style upgrades are coming haha!

Use the pump to pull the oil through the turbo. Have a small reservoir mounted above the turbo that the pump pumps into.

Just an FYI, it burns oil because the Carb is pulling a vacuum on the compressor side of the oil seal that wasn't designed for vacuum. They sell replacement seals that are designed for draw-thru setups for this exact reason.

Yes! Ethan is right! Plenum 4 itres 👌 use that pink bottle from the oil system as your intake plenum

What a fun channel man. Premium. Straight up kraft

I made this exact turbo set up on a 140 mini bobber 5 years ago and I set up the oiling the same way “through the internal pump” and it smoked it still blew the seals

You need a high volume oil pump when running that plate on the head. I don't supply enough pressure to push through hoses.. ive built 100s of them pit bike engines from crf50 to the china special.

Hey.. you gotta love these guys.. at least they are not sitting in front of their computers, they are in the shop building something! The XF 85 Goblin, was not built by complaining on RU-vid.. lol
