Johnny, you should mill out some 1 piece rotors for that blower and open up the ports so it actually flows air.

The sound never gets old, and hearing it on a moving chassis outside is just fricken amazing

You need to ensure the fuel tank remains pressurised by feeding exhaust pressure into it. this way, fuel is always forced into the engine.

It stalls sideways because the wheels have stopped turning ! It’s lost its forward momentum, at low rpm you have practically no torque available from the motor, it’s not a diesel engine & you have a huge flat spot in the power.

I have dreamed of seeing a V8 RC car since I was like six thank you for making this I couldn’t stop smiling

A heavier flywheel may help with the shutoff problem.

The effort and determination of this guy is insane. Every time I see one of your video's in my for you page I don't even hesitate to click on them. I am proud to be one of your 1.87M subscribers!

That is becoming some serious automotive design, i mean that colling and exhaust, you grow my man!

If you think it’s fuel sloshing make baffles in the tank to reduce the liquid movement. And also the low rpm if you throw the drift tire with a plastic sleeve you can draw your conclusion of fuel loss and or rpm being to low

I’ve been watching since you got the V8 and I’m stoked to see it driving and skidding around bro, well done 🙏

I'm just impressed with how well it starts, I've seen lots of others struggle with these.

Φίλε Έλληνας είσαι σε βλέπω τόσο καιρό και δεν με πήγε ο νους ότι είναι Έλληνας. Μπράβο ρε φίλε συγχαρητήρια, τέλεια βιντεάκια

Best v8 rc ive seen running an driving so far on UKposts....❤

I bet youre so happy to see it coming together. I know your viewers are. Way cooler than normal RC cars nitro or battery. Well done.

its been more than 2 years followed you and i'v seen this little thing grew and now its 90% finished i am so proud of you. gg and continue let's go to the 2mill

This thing is so dang cool! Thanks for sticking with it and continuing to share!

U could cut a two slots into the metal, to maintain balance of the clutch and into the friction material, and use two dowel pins plus a lil glue to keep it from delaminating!! Just a thought!! Keep it up, love the Vidz!!!!

This dude and these builds inspire me to go learn how to do stuff. So freaking cool. Thanks for documenting this for us, Johnny!

Just get the four- stroke sound is amazing. Phenomenal piece of engineering all around!!

I bet that felt great getting it out for a spin congrats bud awsome work

Great test drive! It sounds so good! Thanks for sharing JQ90!

Awesome video as always, Sir. Long time subscriber. As an American, I always love seeing a fire breathing V8, in any form. I hope you can get the blower figured out. Keep up the great work Mr. Q90!

I will like to shrink myself so I could drive it. Dispite the repairs it needs I still find it perfect and awesome. Great work Johnny.

I've been waiting for this video for so long and I'm glad it's finally here. But also I can see it needs some refinements in the power band, especially in the low rpm, knowing your potential it would be amazing to see you make turbos like you did for the twin cylinder 4-stroke, but have two different sized turbos and connect them in a compound setup so that way you can get the most torque down low and horsepower up high.

That rc has 4 more cylinders than my Subaru 💀

That's absolutely epic!!! Great job man!!🙌🏻👏🏻

make it loud

At first I was worried JohnnyQ90 wasn't devulging that he is sponsored by Toyan or Sterling Kit, and that he actually gets all these engines for free. You're supposed to let people know if you're sponsored. To be honest, though, I think these videos have made me want these small engines less and less the more of them I see. Imagine spending $1700 on this "supercharged" V8, plus everything else needed to get it to run (and even more if in an RC chassis), and the thing just breaks almost immediately because of terrible manufacturing and tolerances. I'll stick with enjoying watching someone else spend tons of money on getting them to work right.

creating a body for the car once it is mechanically sound would be so cool! , it would literally be a mini car! , great vid once again!

So exciting to see that beast off the chain and thrashing about! Just like any scratch built DIY project, things are going to happen. I have 100% faith that you will work out the bugs. Looking forward to the next update!!

very exciting V8 sound! great work!

glad to see it finally roam free on the ground! all that work!

Thank you good sir for making our dreams come true! 🙏🙏🙏 A V8 RC... 😍 What a great set if skills you have!

It seems like there is a lot of hope for this project to actually come all the way through. Looking great so far and I can see it getting the last 25 percent improvement and then it probably will be the best rc car of its type on UKposts. It starts, the throttle is responsive and its fast enough to warrant the effort.

That sounds awesome dude holy fuck. This is like the next level in realism. Hearing it pass you even at those low speeds is insane

Amazing ! Superb ! Congratulations !

Δεν περίμενα ότι θα έβλεπα τέτοιο διαμαντάκι στην πόλη μου! Πολλά συγχαρητήρια!

Μπράβο φίλε , Πάχη Συνέχισε έτσι, Και πάλι μπράβο 👍🇬🇷

What a sweet ride - love the sound

Sick! Love seeing them drive and operate

im excited to see you make alloy rims next ep!

This thing is so sick, can’t wait to see the final version

I can only imagine how long it took you from concept, to making this video of it driving. R&D is an unimaginably arduous task of success & failure, until you get to the point of consistant successive runs of pure V8 stomping runs of smiling, until your face hurts. Some people think making these "toys" is a waste of an adult's time, energy & resources. What low brain wattage floofs don't understand is, this is the very type of activity which gives some of us a reason to wake up on the weekend mornings. Never stop researching, developing, assembling, testing, & succeeding!

Dude these videos are so friggin' cool.

Fantastic model !!! Can’t wait to see it with the supercharger working and a flat out run for top speed. Not much into drifting and burning up the tires. Would love to have one of these, first one I’ve seen with the actual engine being used in a vehicle.👍🏻

Johnny is an engineering genius!

Very Cool!!! Such a unique sound for an rc!

i think part of the reason it stalls when u slide is causee the engine just doesent have enough energy to keep going when the wheels slow down after a slide. real cars do the same if u spin and dont disengage the cluch

Excellent stuff! I think you might benefit from a baffle or two (or foam) in your fuel tank.

CONGRATS 🎉👏🏆

Ein Geiles teil, super Arbeit .

This thing's gonna burn some rubber 🔥🔥🔥

Sounds awesome !

Pulling air bubbles into the fuel line. Add a splitter with 2 inlets inside the tank. Or a piece of fuel filter foam to stop the sloshing.

This guy is smart and clever to figure it out, he knows his car well. Dude built it from scratch

I agree with a lot of these comments about the stalling issue. I’m leaning towards the idea that was mentioned about the clutch being still engaged while the car comes to a complete stop. That would definitely stall my car at least. That also probably played a roll in the clutch breaking. If it’s a fuel issue though, my suggestion is try a bigger fuel line, and a carb bowl if they don’t already have one. The bigger line will keep it from hydro locking, and the bowl will help with whatever air still gets through. As for the super charger I’m on team solid rotors lol. Those have to be one, solid, smooth piece to get rid of the slap. They have way too much wiggle being three pieces each. In other news; line lock? Totally unnecessary and would probably destroy the transmission but man would it be cool if it worked. Just sitting there roasting the tires and then turning it off and peeling away. As always, love the video. Keep up the awesome work, and I can’t wait for the next one.

I'd add a baffled fuel cell to the list too, maybe put some foam in there and or make something custom with a baffled swirl pot built into it, the sort of thing you see on drag cars. The sudden direction changes and inertia were visibly causing the fuel to climb up the side of the tank which as the fuel goes down are probably starving the feed line.

It sounds awesome!

I can't wait to hear it tuned!

This thing sounds good!

Круто получилось, осталось только корпус подобрать и будет пушка 👍

It sounds cool as hell 🤙🏽

thing sounds SOOO good man! Id go to a positive pressure fuel system like nitro cars run normally where it gets some exhaust air to pressurize it

Sweet! So glad you're at the testing phase. I've been watching the build process and am REALLY IMPRESSED! I don't know if anyone has mentioned it yet or I may grant forgotten if you already thought about this, but have you implemented some runaway protection? You know, how to make the car stop if it loses contact with the radio while under full throttle. Always an issue with nitro RC cars.

Amazing totally 👍 on board with your drive in making outer perfection on a machine that’s thrills the senses of WOWness in the ability to create kudos to you bro 🎉🎉🎉🙏👍

Wonderful progress Johnny sounds like a nascar

About time! Make it run alrwady

sounds sooo good!

Really freaking awesome!

@JohnnyQ90 - just a thought: set up the throttle and clutch actuations on the same servo (or multiple servos from the same channel) - as you give it more throttle, the clutch starts to engage, and as you let off, the clutch disengages. This would take an incredible amount of fine tuning, but I’d imagine would work extremely well, but still provide that realistic functionality you’re looking for.

That is absolutely awesome😮

Keep it up johnny your just too cool 👍

This thing is cool man!!

first time ive ever seen somone actually do work other than idle, great job! looks like a better application would be a monster truck or rock crawler

My guess is rotor shaft flex and the tolerances of the supercharger synchro gears: -That tri-lobe rotor looks to be a 3D ratio, with 3 segments I doubt it has the rigidity to stay straight under boost. -The synchro gears would need to have insanely tight tolerances and sub tenth backlash to maintain the lobe seal with such small gears/rotors. Even operating with a wet seal design. -If you do decide to make your own rotors, may I suggest a helical tri-lobe.

This is dope, I like what ur doin!^^ Awesomeness!, thx for the good vid, with NO MUSIC, just true sounds, including tools, very rare today!! \O>

It has a terrible understeer, the car doesn't want to turn. And if you apply too much power, it immediately oversteers. I suggest you check your differential (if exists) . This issue causes extra load to your engine and clutch while turning. The car came from a long way, and I love how you build it with great effort and create quality content. Keep on, friend across the pond!

So awesome to see it driving...

Dude, ya got this!!! 🤘😎

The comment about the tank needing to be pressurized is correct. They flow a lot of fuel at WOT, and the diaphragm pumps in the carbs can't keep up with it unless you have some tank pressure. You might look into sintered bronze for your clutch basket. The hotter it gets, the better it works. You may need a bit stronger return spring though.. Other than that, pretty good run for the 'first' time out!!😄👍👍

I would love to see new rotors for the supercharger!! There's so many videos out there with little superchargers and turbochargers for micro engines like this and none of them ever work. it's so sad I want to see one that works. you can do it!!

Great video!

It’s getting faster and more responsive 👍

Using the exhaust to pressurize the fuel tank is good. Putting partitions with small holes into the fuel tank might help with stalling when sideways. that way the fuel doesn't slosh around as much.

stalling- could be fuel pickup location on your tank you are using, also can play with the length of the hose from the exhaust to the tank to help keep constant pressure in the tank.

That thing sounds so mean. Love it

The sound is so good

I think a 7.5cc nitro engine 1 cilinder wil outperform all those toyan engines. Sad but treu. I still love it that you try making them work!!😍

Need a locking slot or slots for the clutch lining or something. Really neat project!

Nice to see it driving :-)

The sound is brutal

It has a very realistic, very scale look to it's speed, power and stance.

It would be interesting to spin the supercharger at operating RPM without the engine, to see how much air it moves. I think these tiny engines are too small for forced induction to work properly. And I think the tolerances are probably just good enough for them to run, I think any substantial level of boost would bend things or just end up being lost as blow by. I'd love to be proven wrong, though. "2 Stroke Stuffing" gets an astounding amount of power out of a 50cc engine, but that's only one cylinder, and it's actually designed for vehicular use.

Then start from control is very important and awesome

Badass good work

You could fill the gas tank with race foam it prevents the fuel from sloshing around

Sick. 😯 You are getting close. She is going to rip. Thanks for letting us come along. 🫡

Hey, here's an idea. Keep doing what you're doing, as long as you are having fun. I enjoy watching a builder working things out and growing a skill set. Hopefully, some sponsors will help with more tools and connections to push you more. It was my first time watching you, and subscribing is not a question for me. Subscribed. It would be nice to see you in the comments if you have not already.

I think the stalling is many things at the same time. - low torque at low rpm. You either need to have the clutch slip or do a burnout to maintain enough engine rpm. Your lose all speed forward which forces the wheels to stop. You don't have enough gears in the gearbox to help keep the engine rpm. - add some baffles in the tank - consider some exhaust to add fuel pressure. Great video. But maybe not so great for the supplier of the compressor. It did have issues even before you installed it, being silent in only one direction. They need to step up their manufacturing quality and testing.

Sounds much better sans blower. I wanna hear it through 180* headers. Thanks for the vid.
