I love how Ethan can just make any part he has in mind, creativity, skill and thriftyness!

I have a feeling it won’t take long until they’re gonna nitrous the thing.

Again, just so satisfying. Also: production values are still impressively on the rise, great stuff

Ethan: “luckily I was able to fix it with my retainer I saved from 8th grade”

I'm so glad you guys exist. I freaking love the muffler housing, your fantastic adaptability, the music, and damn dude that outro drone shot was lit.

That type of system does not require a blow off valve, its creating a huge vacuum leak when it opens. Only time you need a blow off valve is when the throttle plate is post turbo/supercharger.

Nothing is better than coming inside tired and dirty from working and seeing a notification from you guys🤘🤙

I would remove the blow off valve, with a draw through carb configuration and the BOV located below the supercharger its not doing anything useful anyway.

Just realized how close yall are to 1 million subs

Heck yes this is so cool I can't wait to draw this

The 3 Ps that got me hooked on this channel: the people, projects and the production quality. Keep doin you guys. This beats the hell out of any tv show.

Your fpv piloting skills continue to get better and it adds a nice touch to the video the way you edit in. 👍

so rad!!! also the production quality is amazing. feels like im watching a tv show

Sick builds guys, I love watching all the projects! Better then any TV show out today!!!

You guys should do a bloopers / outtakes on the bonus channel!

Crf450 that’s supercharged?! That thing should make some power baby!

When you think that you've seen everything on the internet. Then this comes up on your recommended.

2080: My crazy grandpa; the Grind Hard Years.

The carb will shut the air off going into the charger. The blow off valve is just a leak and headache with the setup the was it is. If the carb was after the supercharger and the valve was before the carb then the blow off valve will work as intended

Ethan you’re a very talented machinist it would appear that between your homesteader type demeanor and your brilliant insight that you should have your own machine shop. You’d be excellent at it and you’d probably make a lot of money.

You could consider recirculating the blow off valve back into the intake, post filter. Might loose a bit less air fuel mixture under boost. I'm super stoked about this project. Keep up the good work

Your fabrication skills are just exemplified by the videography skills utilized in the making of your impressive and entertaining material. Keep up the good work, you guys! It will grow faster than you expect in a short time!

Grind Hard Plumbing. Cool build guys, make sure to give her more ring gap before you bust a piston, also are you running any kind of fuel pressure to the carb? You will definitely want to, also get a larger bowl or atleast set the floats as high as you can before it starts spewing out. Just a couple tips for you guys.

Sendy revs out so quick....I've always felt it needed a taller gear....maybe 2 or 3 teeth

WE WANNA SEE A 2STROKE POWER WHEELS BUILD

That thing looks scary fast without a supercharger🤯 Awesome job on the pipe👍

You gotta get a Tig button. There is one make I have seen that is pressure sensitive and comes in various connectors for most brands

That moment when you realize that a barbie jeep has more hp than your motorcycle you daily ride

Now put Twin Turbos on Colonel Senders!! XD

I have watched you for a while now and I must say that your timelapse/videoedits are freaking eyecandy! thanks for the good quality edits and your content is super cool and funny! thumbs up from Finland! :)

please remove that BOV... i smell fire danger!

man i love this channel

Subscribed cause he still drove with out it being tuned and I respect that cause it’s exactly!!!! What I would do....

Truly f'n awesome man! The knowledge and ability to custom build parts and solutions like you do, so interesting to watch! Wish I knew this stuff. Rock on man!

every single time you post your story its an inspiration to so many people out here and I can't thank you enough for allowing us to be part of your journey through this life

Come for the lathe, stay for the supercharger 😎

I was watching this on a vr headset and the fpv part is the coolest thing

Just the ride through those woods shot is epic itself.

Just a note guys, you do not need a blowoff if you are running the carb on top of the supercharger. The only reason blow off is required is when the throttle slams shut and boost is jammed into the closed blade. If your throttle is on the vacuum side of the charger and not the boost side then you have no boost cramming into the throttle body. You guys are doing fantastic!! Love it all!!

Throw a lectron carb on it probably be easier to get it running smoothly

14:17 was like that looks like a Subaru blow off valve flange and then you said you got it off a Subaru so that's probably what it is

It's such a relaxing, satisfying, high quality content... I've been builing a motorized gokart out of a kettcar and a pocketbike engine when i was 12 years old... That thing was already running well... Seing these video tho, 9 years later, makes me want to go back to builing one day...

Boost is a measurement of accumulation, if the motor consumes more cfm than the charger displaces it will show reduced pressure on the gauge, calculate the cfm produced per rpm V motor cfm and you will calculate a given ratio, to be honest your behind the 8 ball using a small displacent charger, awesome work as usual I thoroughly enjoyed it 😊👍

Sure, point the thing that sprays atomized fuel at the drivers crotch.

Is this motor a single or dual cam? You might end up needing some new cams with slightly larger lobes. Probably do some slight milling to smooth the intake/exhaust flow. Make a timing adjustment to finish off. Maybe even play around with the jetting. Alas, great video! I'm looking forward to the finished upgrade.

This is such an amazing video thank you for sharing your experience i can never get enough ❤

Thank you guys for making awesome content with no bad language, my son and I love watching your videos together when I get home from work. I am a mechanic, and its in the DNA my sone loves cars too. So thank you again for what you provide!

Uploaded 2 minutes ago, 110 likes, on a 20+ minute video! I see I'm not alone on liking these IMMEDIATELY without even watching?!! I am now

What's the point of the BOV? It's after the throttle, so it's not really bleeding off excess air, more just acting like a vacuum leak when it opens

Dude that new muffler sounds so good on my theater system it sounds and feels like the thing in my liveing room

You guys amaze me. I have alot of ideas i never do anything with. Less timing, more fuel read the plugs after a good chop. Belt tension for sure. Nothing makes measurable boost without load. I bet the higher gears will pull way harder than before

No long sleeves on the lathe! Love the builds tho.

What was holding up Ethan's hoodie string in the opening shot, his beard?

Just started video and I can't believe that exhaust is restrictive. Its nearly 2" on a motor that size. There are cars out there with bigger motors and smaller exhausts than that haha.

Genuinley love your work, really satisfying to watch.

It would be so cool if the blow of would go into the exhaust and shoot flames if it opens.

Oh boy this is gonna be good!

I could watch that drone footage through the trees all day.. Reminds me of Star Wars lol

Firefighters truck 🚒 big wheels! With working water tank would be insane!!

17:25 lmao

Needs more fuel!!!!!

It's so cool to reuse stuff on your projects rather than just buy something. Great job.

That was a ridiculously awesome drone shot as Ethan was coming back from picking up the mail!

Where did you get your muffler packing from? Ive had trouble finding good stuff in the past.

Definitely will need a much larger set of jets. Also, keep in mind that at part throttle you shouldn’t be seeing boost. What happens is that you reach your maximum volumetric efficiency much quicker at part throttle opening, usually resulting in torque increase right off the bottom. Keeping in mind that 0 represents 100% VE. Once you have a chance to wind it up slowly and hold WOT that will give you an accurate idea of your producing enough air volume to hold consistent PSI or if you need to play with your pulley sizes. These generally work well with carbureted setups so i’m excited to see where you end up!

i have to say that the intro with the beard / hoodie laces was nuts!! don't know who thought of it 1st, but that was a gem

These guys have all my dream toys

This has been a bit of an inspiration to continue on a rabbit hole I've been chasing for a bit. Thank you for the ideas and content you guys always make my day.

When you hit 1 million subscribers, you should do a giveaway so one of us fans can win one of your creations! Colonel Senders FTW!

Ethan is the King of packaging! "fitting big things in little places"

I wanna see what this makes on the dyno. This thing is badass!!!

Looking good lads looking forward to cindy being tuned nd ripping the track and hopefully beating her own track record. 👍🏻👍🏻

Absolutely brilliant work and content, as usual Guys! Thanks so much. Rich.

Nice. If you know fcr carb tuning . The acelerator pump. Squirts a shot of fuel every throttle wack. Typically best to face this squirt enter the carb asap just delayed enough the slide is out of its way. Also theres a bleed jet in the inside bottom of the bowl. Making it smaller or plugged will increase the ap squirt amount. . Applying boost pressure to the bowl vent should increase main jet flow .. and adding it to the fuel tank vent . Will increase fuel psi while under boost also.

Others noticed these too, but mentioning them anyway: That BOV does more harm than good. U have no intake before the carb where overboosting would cause issues. After the fuel mixer, it causes only mix issues and intake leaks, leaning out the system. Even in large systems they use solely burst panels to dissipate backfires, no actual valves, for this same reason. When you have active mixture tuning, as in EFI, you can control the boost level before mixing the fuel into it. But in mechanical wet system, you just need to direct the flow into the chamber. The carb+slide handles the amount of A/F mix, the screw just packs it up a bit. You can alter the psi level by changing the gear ratio on the belt drive. O2-sensor bung would also be a nice addition to the pipe. You can use it to tune the carb, and when finally converting it to EFI, the bung is already there.

Blow off valves are used only in turbocharged-engines and its purpose is to relieve the pressure built up within the air intake system that is capable of stalling the compression wheel. A true supercharged engine works using forced induction which internally channels the air pressure back into the combustion system and compresses it using a pump. A turbocharger works on the same principle however it uses a turbine and the exhaust from the car’s engine to provide the necessary compression in the air system, not a crankshaft driven pump

Ethan, is the BOV opening and dumping all the intake charge out causing it to fall on it's face? Personally, I'd start there. Maybe blank it off and see what happens before you go messing with the carbie jets. Also, it screams FIRE HAZARD to me.. How about a vent tube to dump it away from the hot engine? Hmm.. or into the exhaust so it shoots flames out the back? Heh. Flames!

So close to 1 mil... can't think of anyone who deserves it more

It's amazing that you could turn that aluminum 90 into the PERFECT flange for the supercharger just by hand porting and shaping!! You should change the 90 you have going to the carb to match the same excellence as the one going from the supercharger to the engine!

All my grand daughters want this. You are amazing in the trades..well done.

The boost coming in when you blip the throttle totally makes sense. With the afr obviously being lean due to introducing significantly more air without any more fuel, it will lean bog when you gradually open the throttle. However, due to the nature of a pumper carb, whacking open the throttle squirts a jet of raw fuel into the intake giving you the necessary fuel to make adequate power. But once that squirt is gone, she goes super lean again and bogs/dies. Good luck with the carb tuning. There is a lot of trial and error when going into uncharted territory like this.

Look forward to seeing this one once you got her rippin🤙

Forced induction with anything carbureted is always a pain to get dial in. Takes a lot of tinkering but keep at it as we all want to see it roast the tires!!

Really cool. Thinking it will be a Ripper once it is buttoned up and tuned. BTW, somebody is getting really good at flying the drone!

It needs a proper fuel regulator, you may need to increase fuel line pressure proportionally with the Boost pressure. Boost pressure kind of “fights” back on the jets and starves your engine during full opened throttle. Great Job mate! Very looking forward to see it running. I have similar project here on a 1967 two cylinder 4 stroke, but i will be running injected with a FT250 Fuel Tech and electric fuel pump on E85.

You may need a high pressure fuel pump to counter the boost pressure in the intake pushing back on the jet and/or I have heard that running a small boost line to the bowl of the carb works to counter the pressure too?

Great project 🤙🏻

Awesome builds guys, can't wait to see more. But I'm sure I'm not the first to mention it in the comments, but they blow off valve isn't necessary for a draw through supercharger setup. The section you have put the blow off valve on is under vacuum when the throttle is closed, as is the supercharger. So if the blow off valve did manage to open, it would actually draw are in, not release Air out. I have a funny feeling that's why it's sort of ran away when you started it the first time and thought the throttle was stuck open lol. Just constructive criticism. I love what you guys do, always entertaining to watch :) cant wait to see more :)

Awesome build! You guys have some mad drown skills 👌

I don't mean to nitpick, but a BOV on a draw-though carb setup is probably not a good idea. The throttle plate is limiting airflow into the blower, so no BOV is needed. Plus, you're venting fuel/air mixture. That said, the cam driven setup is pretty ingenious. 👍

That fact that it now has exhaust pop is awesome

I dont think you want a BOV with that draw through set up. Wouldn't it just blow fuel out and F up the mixture/stall it?

you know you're a badass when you can use you barbie jeep's tire as a grinding surface.

That thing sounds wicked Love it 🔥👍✌️

French gang of midnight. No seriously how could we miss a video of GHPC

Cant wait to see it tuned and hopefully making more power

Plumb in some small high pressure lines from the pressurized intake elbow to the carb vents for the float bowl. You’ll have the equivalent of a boost referenced rising rate fuel pressure regulator. You’ll need to fab a ‘manifold’ that allows for one way operation (so the float bowl sees atmosphere under vacuum) and a way to bleed off boost pressure to the float bowl to give you some adjustability with the fueling under boost. That will probably solve 87% of your fueling issues.

this is the most incredible thing I have seen in a long time!!

I loved that snowmobile reverse trike
