Part 5 is here! kzfaq.info/get/bejne/h5emnKalv8zSm4U.htmlsi=5viA48zgG1itPQwM

To accurately measure your pressure drop over the cooler, just put two pressure gages in, one before the cooler and one after. Subtract the two, and there is your drop. Pressure is flow dependant, and it is best to do on the actual motor, so that's consistent. My feeling is that it has plenty of flow. An automotive cooling system runs around 1 bar of waterpressure (i think you could be running 0.5 bar at best). Water is way more viscous than air. Again, I love the work!

The only thing I hate about these videos is when the video ends 😢 keep up the amazing videos bro. Kia Ora from New Zealand 🤙

At one point wasn’t this a budget build drift kart🤔😂 amazing job 👌🏾

You won’t get enough boost to ACTUALLY use that intercooler. Turbos work on pressure ratio’s (at the inlet) as a function of engine flow rate (corrected for flow rate for ATMOSPHERIC pressure). You won’t get enough revs out of a 125 with a good volumetric efficiency at the revs you’d be running anyways to get any sort of meaningful boost (even with that tiny turbo) BUT if you compound turbo it and you factor the pressure ratio’s together… so 4psi of boost (1.27 pressure ratio) increases to 9psi of boost (1.27x1.27=1.62 pressure ratio) which cause a ‘chain’ type reaction in the system to actually force more flow rate and then force more boost. You’ll see probably 15+ pounds of boost with a compound on that motor and with the fuel injection would run great and then you’d actually be using the intercooler.

Imagine a bash bar front and rear

I celebrated so hard when I saw this post

OMG! That is siiiiiick! Love this build coming from a humble 49cc to a full blown turbocharged, EFI 125cc death shifter go kart love it mate! Can’t wait for the end results of this bad boy.

Thank you for all time and effort that you put in these videos

Thing is lookin WiCkEd ! Could imagine a alu sheet cut chin spoiler across the front and a Alu sheet one off aero spoiler on the back

Not sure why automotive youtubers doesn’t do things like this more often. Its a portion of what a car build would cost and it brings curiosity out of potential subscribers. It only attracts viewers.

When this is finished, you've gotta fit a home-brew spark plug flamer kit haha

finally one guy it’s doing well this kind of tuning, i never saw something like this, you’re very talented 👏

Put a cap, with an air line on one side of the intercooler. Get a baseline of what the inlet pressure is. Put an airflow meter on the exit side. Calculate the difference.

Glad you saw the comment on the intake side and took note! Looking forward to seeing how it turns out!

That looks very cool 🔥

Hey I built one close to yours last year, very fun build! Pro tip-find a power wheels body of your choice I.e: mustang, bmw, truck, military tank. Hollow out, mount over body, and slam it. Looks fantastic!

Wow nice to see you reading the comments and responding to the plenum I think your right the intercooler should help do the same process and store boost so fair play bro I love it ❤don't forget about your vacuum pipe for wastegate

The scale of the intercooler is hilarious! It looks so fricken cool though, the pie cuts are beautiful. Way too cool Mike! Really gave this thing a birthday. Excited to see it in action. Also, I do agree the intercooler would do similar things as a plenum. Adding volume. Smart man.

Keep it coming killing it very high standard 🫡 your learning lots of new skills as you build not bad for cool lil turbo quad next project needs to be something mini too 😬🏴󠁧󠁢󠁥󠁮󠁧󠁿

You could measure the pressure drop by static pressure. Fieldpeace makes a static pressure meter. You’ll have to rig up something like a leaf blower. Connect the leaf blower to one side of the intercooler and you’ll have to put one hose on one side other hose on the other side and measure the static pressure. or something.

This build has got me hooked.

Awesome work Mike!!!! Love to see your talent and ingenuity on such a killer project. That wheel and hub fit nicely in my Infiniti g20t btw! Thank you again for hooking me up with such a killer piece

can’t believe you bent the fins on your brand new rad/intercooler

The build looks so sick mike I'm loving this drift cart series I can't wait to see you ripping it around

It looks mad with that Intaculer and everything tacked up looks sick as cant wait for it to be done

Haha , i have an 200cc motorcycle in storage almost for almost 10 years. I wonder if it will start and slap a turbo on it 😂 #turbolife 🎉 Love the build!

Been excited for another episode of this, i'm strapped in and ready 😎

Good onya mate. Quality content very engaging. Looking forward to the rest of the build.

Front mounts just make anything look tough

Killed it!!!

Tilt steering column would be sick

I was thinking about the flow and pressure drop before you mentioned it... and I actually think, that because of the time it takes for the pressure wave to reach the inlet after it's creator has left the exhaust port (the reason there needs to be a chamber to store boost rather than send it backwards like a two stroke exhaust does) the higher pressure on the hot side may stop bleedback from the cold side. the pressure difference may just work to your advantage. I'm also thinking that 2 boost gauges (one on either side of the intercooler) for testing purposes would be interesting, But yes the standard is pretty damn good. It's looking awesome!

Bro that looks so good!!

Thats insain what a build for a quad / go cart one of a kind keen to see the finish well done bro

An old top mount intercooler off a series 4/5 RX7 or top mount off any early WRX would work perfectly.

Bro this things gonna be soo fast when its done 🤘

Love the progress! Can't wait to see it start up!

Can’t wait for the end product know it will look good 👍

Have to be my favourite youtuber atm and such a killer series! love the work

Love❤ from India😊. I think you should paint the frame black and maybe 🤔 some more joints.

that intercooler is epic. everything is looking awesome bro! good content cheers

Nice Fab skills!!! Love seeing someone bring the imagination to life!

YEAH BOOOI!!! All the reason to be proud Mike! It's looking SICK and I look forward to next week's video! 🤘🤘🤘

Really enjoying this series so far! Maybe you should try running nitromethane in the car? It will give it an extra bit of kick. Must richen the mixture though.

Hurry bro im stressing i need to see this next part 😂❤️

love the qaud man

Sick video!

People witch think he should take it to the Dino 👇👇

This shit goes harder then most drift cars! The ic looks sweet af

This is the best I want to build one eventually out of all the carts this one is my fave 👍

Great job, can't wait for the next vid!👍

This is the best drift cart vedio but it will be better if it has lights ❤ keep it up

stretched tires would look so good on this kart

Tressal tables ftw

What an awesome build i love it !! Hello from Sweden🤙🤘

I'm excited for the next episode so much I've clicked this video 3 times LOL

flip the FMIC upside down for more clearance! cant wait to see this thing ripping

I love how a sound

Things sick bro 🤙🏽🤙🏽

put spark plugs in the exhaust

It's got intacoolah! Fully sick, Bro! So ridonkulous, but I love it

Love the progress. a comment for the algorithm good sir.

this thing is just ridiculous lol love your work man

A great tip that's gonna save you so much head ache and disappointment add a plenum if 125cc shoot for 500cc or a bit more. It won't make much without it and it's gonna be hard to tune. I have a 155cc compound bike that's over 100hp on ridiculous boost it's been a idk how long r&d project of mine and pre plenum we struggled to get any meaningful power. Not to suggest your gonna get over 50hp with one turbo 😂 on a 125cc but you can get pretty close. I prefer carbies but to each their own just when making a new intake you can plum the plenum either between the tb or after but tuning will be easiest engine plenum tb and runner length matters alot they make boost up top as singles and have back pressure issues quick so make that runner longer. Were a bit bigger but saw a solid 20% gain in the usable powerband by making the runner about 10in longer. This is on a xr based engine but similar enough. You can also use the world's fastest postie bike as a great reference I copied a lot myself and when I didn't listen I ended up at the same conclusion eventually like the turbine housings being way too small. FYI they got a semi reliable 60whp on 45psi of boost on a bone stock motor so they can take more than one stage of compressor can give. Looks like your going the vz21 route id suggest a vz45 as the exduser is bigger on the compressor wheel and spends less time in surge along with a bigger turbine wheel so the back pressure is reasonable. Back in our single turbo days we tried everything we could get and the vz45 was best by miles and didn't complain too hard making 30psi although the Chinese so sell billet wheels for them I was able to message seller and get a few custom ones with the absolute limit on exduser size and an extra blade to help the efficiency at higher pr and move that surge line down further. Keep in mind the vz21 wants to see that engine make 30hp before it's out of surge and the vz45 only needs to see the flow of 20hp the custom ones we have would get happy around 20hp too but we were able to lean on them all the way to 50+psi although they don't live long after 40psi as they have a 270° thrust bearing. Carbies make the mixture cooler and you can chill your fuel with dry ice and well we don't need an intercooler although the latest version does have two and it certainly helped us get over the 100hp mark. Oil pressure is an issue although if weight isn't a huge concern an electric pump would be best then you could have a totally independent oil tank just for the turbo.

Looking sick as bro love this series

loving the build mate if you have trouble getting the intercooler to flow Rb racing in the US make mini intercooler's for harley davidson's

Love this thing brother!! Cant wait to see it dosing lol

Bro is slowly building a race car

Wish my kart was as cool as that

On the hot side you should have made a full loop with the pipe. It would look SICK AND GIVE YOU MORE LENGTH AND VOLUME annnndd would look like you have like a 2nd turbo sorta if you can picture it you know what I mean

Looks sick

Make sure u think about crashing the thing while building. Yes the front mount looks tough as on the from but it’s now in kill zone if u send it into a street sign😂😂 Maybe a small “bash bar” underneath the cooler poking out slightly so there is something to hit just in case. Love the video man. Here within 15min😂👌✌🏻

looks dope af love the the videos mike....

the turbo needs a dose pipe!!

All I have to say is to get some grommets on that rad. Bc the mounts like that will be destroyed. You’ll be in a world of trouble. Bc it’s going to vibrate a lot. All that vibration is going to find its way down to them mounts and break off

Id love to do this with my ssr dirt bike motor. Haven't decided what I want it on tho. Its on a janky go kart rn.

I’ve been waiting so long for this video 🎉❤

Daaamn😍❤️ excited to see next episodes

make a cage for the intercooler so it dont break

SHEE, taking it to the moon!! 😍😍😍😍

this i crazy insane

Oh yeah ur going Intercooler woops my bad . Frk yeh

Should have used a crf150r motor. Skitz build though mate keep it up

WAKE UP THERE’S A TURBO QUAD BUILD UPDATE

You need a chop saw lol but loving the content!

you need to cut them ugly triangle bars off the front and make two brackets and get two minie quad bike shocks and put them on the front like coilovers that would look nuts with the intercooler and would give it more of a drift kart / drift car look

It's 3:42 for me lol

If the cooler doesn't work try a kei car or a stock rb intercooler

Just curious are you using a bandsaw to cut pies??

TWIZTED FCUKING SICK ....BADASS LITTLE KART

Flamethrower kit plss❤

What efi set up is that. I was doing a atmosphere box on the carb but interested in that set up

Yo love the vids man keep it up. Btw what was the pipe/hose called running from the radiators to the turbo?

ooft, If it was ready, you should have definitely taken it to vicdrift 👌

nice upload

Put a scoop air dam with a screen

There is a guy on KZfaq call Sean N that has a turbo kart that will boost over 20 psi that uses an intercooler. Unfortunately I don't think his will even do stu stu stu.

Should of used a factory skyline or wrx factory intercooler

Starting to look sick as fuck dude keep it up
