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

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

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.

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!

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

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

That rc has 4 more cylinders than my Subaru 💀

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

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.

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

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

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

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

make it loud

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!

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

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

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

Amazing ! Superb ! Congratulations !

very exciting V8 sound! great work!

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.

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.

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

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

Sick! Love seeing them drive and operate

What a sweet ride - love the sound

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!!

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

CONGRATS 🎉👏🏆

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!

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

Sounds awesome !

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

Johnny is an engineering genius!

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

im excited to see you make alloy rims next ep!

Dude these videos are so friggin' cool.

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 KZfaq. It starts, the throttle is responsive and its fast enough to warrant the effort.

It sounds awesome!

Ein Geiles teil, super Arbeit .

Really freaking awesome!

It sounds cool as hell 🤙🏽

sounds sooo good!

That is absolutely awesome😮

This thing's gonna burn some rubber 🔥🔥🔥

This thing sounds good!

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!

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

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

This thing is cool man!!

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

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

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.

I can't wait to hear it tuned!

Badass good work

Keep it up johnny your just too cool 👍

Dude, ya got this!!! 🤘😎

Great video!

So awesome to see it driving...

The sound is so good

Great job

About time! Make it run alrwady

Nice to see it driving :-)

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.👍🏻

Wonderful progress Johnny sounds like a nascar

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!

@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 SUPER cool 👍👍👍

You are awesome!

Then start from control is very important and awesome

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.

That thing sounds so mean. Love it

this is dope

The sound is brutal

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.

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 🎉🎉🎉🙏👍

Круто получилось, осталось только корпус подобрать и будет пушка 👍

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.

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.

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

It’s getting faster and more responsive 👍

What a nice toy! 😃👍

Would putting pressure from the exhaust to the tank help with the stalling? Kinda like they do or did with the 2 stroke RC engines? Just a thought. I could and probably am way off base though. Either way, still an awesome video and car. Thanks for sharing.

I’m really excited to see it god

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>

that is awesome

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!

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!!

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.

the motor shutting off when skidding could be something like the oil going to one bank of cylinders instead of staying in the pan? but then itd start running way rougher so idk. maybe you can add one of your older centrifugal superchargers to it instead of the roots blower? with only the one turbine it shouldnt have any collision issues.

Hell yeah naturally aspirated V8 glory :)

lets go! awesome
