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!
Bro, you’re so damn smart! I really appreciate this advice. I’ll do the pressure drop test in one of the upcoming videos as it’ll be super interesting.
The only thing I hate about these videos is when the video ends 😢 keep up the amazing videos bro. Kia Ora from New Zealand 🤙
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.
At one point wasn’t this a budget build drift kart🤔😂 amazing job 👌🏾
….I got carried away 😅👀 haha
I celebrated so hard when I saw this post
Same
Imagine a bash bar front and rear
Glad you saw the comment on the intake side and took note! Looking forward to seeing how it turns out!
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
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!
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.
The journey has been a crazy one so far hey! Absolutely loving it. Thank you bro 🥰
@@itsmikelake your are so welcome bro. I can tell that you can’t wait for the end results either. Have you thought of installing a waste gate/ dump valve on it? That would be sick as f.
The build looks so sick mike I'm loving this drift cart series I can't wait to see you ripping it around
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
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.
This build has got me hooked.
Thank you for all time and effort that you put in these videos
Thank YOU for watching and enjoying them 🥰
Love the progress! Can't wait to see it start up!
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.
Thats insain what a build for a quad / go cart one of a kind keen to see the finish well done bro
It looks mad with that Intaculer and everything tacked up looks sick as cant wait for it to be done
Nice Fab skills!!! Love seeing someone bring the imagination to life!
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.
can’t believe you bent the fins on your brand new rad/intercooler
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
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
Great job, can't wait for the next vid!👍
That looks very cool 🔥
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 😬🏴
Good onya mate. Quality content very engaging. Looking forward to the rest of the build.
Thank you bro! 😁 I can’t wait to probably almost die on this thing 🤣👌🏻
YEAH BOOOI!!! All the reason to be proud Mike! It's looking SICK and I look forward to next week's video! 🤘🤘🤘
This shit goes harder then most drift cars! The ic looks sweet af
Bro that looks so good!!
Love❤ from India😊. I think you should paint the frame black and maybe 🤔 some more joints.
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!
sounds good i might try that for my drift trike
This is the best I want to build one eventually out of all the carts this one is my fave 👍
Tilt steering column would be sick
Sick video!
Killed it!!!
Thanks bro 😁
Can’t wait for the end product know it will look good 👍
Front mounts just make anything look tough
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!
Things sick bro 🤙🏽🤙🏽
It's got intacoolah! Fully sick, Bro! So ridonkulous, but I love it
put spark plugs in the exhaust
Well probably go one better and tune in a two step button 😛
Been excited for another episode of this, i'm strapped in and ready 😎
😁 thanks for watching!
that intercooler is epic. everything is looking awesome bro! good content cheers
Also appreciate all the time and effort you put in dude!! 💯
Bro thanks so much for the nice words aye. Love reading stuff like this after all of the hard work! Makes it worth it 🥰
Bro this things gonna be soo fast when its done 🤘
Have to be my favourite youtuber atm and such a killer series! love the work
Bro that’s such a rad compliment. Thanks so much! 🥰
Looks sick
love the qaud man
Cheers 🥰
Hurry bro im stressing i need to see this next part 😂❤️
What an awesome build i love it !! Hello from Sweden🤙🤘
Cheers! Hey from Australia haha 😛
stretched tires would look so good on this kart
Love this thing brother!! Cant wait to see it dosing lol
Haha you and me both brother! Cheers 👊🏻
Looking sick as bro love this series
Thanks homie 🥰
@@itsmikelake I want to eventually get into welding it's just abit harder as I'm off grid and have to use a generator for a welder but I'm slowly doing some videos very amateur stuff but it's a start :)
This is the best drift cart vedio but it will be better if it has lights ❤ keep it up
Thanks! Maybe LED underglow? 👀
looks dope af love the the videos mike....
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.
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.
Daaamn😍❤️ excited to see next episodes
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
I love how a sound
Love the progress. a comment for the algorithm good sir.
I appreciate you bro 🥰
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
flip the FMIC upside down for more clearance! cant wait to see this thing ripping
I did consider this but it just didn’t look anywhere near as cool haha. Looks are important 🤣
@@itsmikelake hahaha I agree
Epic !!!!!!
I'm excited for the next episode so much I've clicked this video 3 times LOL
Haha dropping Tuesday!
@@itsmikelake I'm still gonna check tomorrow aha.
this thing is just ridiculous lol love your work man
Haha thank you bro! Should be mental when it’s running 😁
nice upload
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.
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😂👌✌🏻
That you’re absolutely spot on. Likely a wee bash bar is needed for sure. And some brakes 🤣. Appreciate you watching bro 🥰
this i crazy insane
I’ve been waiting so long for this video 🎉❤
Thanks for supporting bro 🥰
make a cage for the intercooler so it dont break
Should have used a crf150r motor. Skitz build though mate keep it up
Haha we can always upgrade for sure! Thank you bro 👊🏻
ooft, If it was ready, you should have definitely taken it to vicdrift 👌
I was literally going to, to display next to the drop the anchor stall haha
@@itsmikelake Next time haha
Just curious are you using a bandsaw to cut pies??
Bailey cuts them for me on a bandsaw yep! I can’t wait to get one in at the shop 😍
the turbo needs a dose pipe!!
You know this is happening 👌🏻
So fricken good!!!!
Bro is slowly building a race car
👀 you’re not wrong here haha. If we’re going to do something we may as well kick it out of the park hey 😁
Tressal tables ftw
If the cooler doesn't work try a kei car or a stock rb intercooler
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
Not a bad call on this one! These things do vibrate more than a s*x toy that’s for sure 👀
@@itsmikelake yea. Theory the motor shouldn’t have move like a normal vehicle. No dampners. But the rubber on the charge pipe should dampen it some. But the air still would possibly vibrate the cooler. Hopefully u didn’t get too far into the cooler building 😂
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
Nice!!
Thanks!
SHEE, taking it to the moon!! 😍😍😍😍
All or nothing babyyyyy
If you like it, I’m happy 🥰
Flamethrower kit plss❤
Guaranteed 😛
There is a guy on KZhead 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.
Wish my kart was as cool as that
You can always make it as cool 😛
How's the tuning going with efi?
We’ll find out when it hits the dyno 😛
Whats the details on the efi where did you get it etc?
Link is in the description of part 2 vid 👊🏻
Put a scoop air dam with a screen
chop chop gokart boy
It's 3:42 for me lol
WAKE UP THERE’S A TURBO QUAD BUILD UPDATE
Should of used a factory skyline or wrx factory intercooler
I have one here. Waayyyyy too big haha
Bro how much do you want for it 😍, I need this thing it looks amazing and very powerful
You need a chop saw lol but loving the content!
You’re so right. I’m so sick of cutting piping with a grinder 🤣 haha thank you bro
Starting to look sick as fuck dude keep it up
You should build the engine
Once this one goes kaput we can!
