I love miniaturization, but fully functioning miniatures are just another level of cool. What a great looking kit.

I think 1/5 RC car is a must in this case, maybe a muscle car with a supercharger and over the hood intake, can't go wrong with a classic!

1/5 scale Hoonicorn replica would be next to godliness. And I believe you have the shop to achieve it now too... your machining skills stand alone, my friend. Clean, methodic, consistent. Been following you for several years, no idea how many times I've viewed your work. Well done, sir!

There was something so satisfying Watchung the cam gears spin as they were installed. The way they spun so smoothly was awesome!

I have 40 years as an R&D aerospace machinist, and this is awesome!!! I may buy one just to appreciate the machining detail and engineering!

Extremely happy to see Toyan finally recognize the need to support a multicyclinder crankshaft at every crankwebbing... That is a HUGE improvement. Maybbe finally this engine can become more than just a showcase gimmick and be a real practical powerplant.... If just they would also support the camshafts on multiple points, and introduce some form of cam lubrication other than grease....

I don't know why but your content is pleasing and the things you do to achieve your goals is just inspirational

Definitely need a 1/5 car to put that in. That would be so awesome. I built NASCAR Cup engines for about 6 years and that looks like a fun project. A lot simpler than a racing engine. I’m definitely getting one of those screwdrivers because I’m constantly using 6 sided bits and that is a awesome tool. Thanks for sharing.

*Definitely needs a twin turbocharger set-up 💯*

Johnny has been gradually going up in scale with his model engines. By 2030 he'll be making full size engines.

This tiny engine sounds better than most modern cars

Those tools used, were extremely pleasing to watch and listen to. The torque drive and the other little electric driver. *Chefs kiss*

Can you make a new crank shaft for inline 4 engine make it crossplane style like yamaha r1 i want to hear it so badly

I'd love to see this in a mini version of those crazy V8 chainsaws that people make for woodcutting championships... *...then* stuff it into a R/C car

And it sounds exactly like you’d think a miniature v8 engine would. It’s so sick.

I would love one of these, but the darn thing costs more than my first pickup truck which had a real LS7, jeeez

A nice Hot-rod style RC car would be awesome, and would make for an interesting challenge to get the drive turned 90 degrees. it'd be a cool way to show the engine off too, as well as all the shiny bits you could make to make it look really cool. you might want to get a polishing wheel for the exhaust. there's also scope for extra stuff like a proper supercharger and scoop that would make for great CNC projects. It might be tricky to find a body that would work, but it's probably do-able on a 3d printer as it could be made in sections. there's plenty of Ford model-A bodies on thingiverse etc. I don't really like the look of those camshafts, they're a bit thin for an un-supported shaft, It's probably not a huge project to make up some split-bushes from bronze to help them survive.

What a fantastic video! Look at how well it's all packed and padded. Amazing! Loved watching the assembly too. Just super satisfying!

gotta love the in-block starter motor design, UZ owners are punching the air right now with that. Looks like a fun build to do, hopefully it goes into an R/C!

13:36 incredible the slow idle it keeps,very pretty

I love it when you bring out these videos. I find myself repeating older videos of yours just purely for mechanical ASMR while I'm sleep deprived at 3am. Keep 'em coming!

That sounds just like a F1 V8 engine. I'd like to see a RC car

Pretty amazing engines. Beautifully packaged.

Having grown up within 100 miles of Detroit, IC V8s hold a special place in my heart.

Wow, a spectacle to watch the assembly of a V8 engine, which many years ago, it seemed impossible to see one like this in miniature! Congratulations my friend.

Make a V8 1/5 RC but a V16 Chainsaw with 2 of them 😄

ok now put it in a miata

i love these videos so much. I need to be at the gym for my training at 7 and its midnight and im watching this. Much love to you

I like the way things are going. You’re moving on to bigger and better things and can’t wait to watch every single video. I’ve been watching for the past three years and I’ve loved every single video. Keep up the incredible work

2 words can describe this little engine..."frickin awesome!!" great job on the build. was that transmission fluid that you used to lubricate the crank and piston bearings? none the less,,, whatever your future plans for this little jem of an engine will always put a smile on the people who have subscribed to your channel. can't wait to see what's next!

As someone that works around engines for a living, this is really nice and relaxing 😅

Thank you sooo much, alot of youtuber would have used a super annoying and loud background music. But this beautiful built was on its own incredible 🎉

It is so satisfying watching you assemble these engines. This was my favourite build so far. Would love to see this in a muscle-type 1/5 R/C car or truck even.

I was impressed until I saw the camshafts are only supported on the ends. They're gonna whip around and break, or the springs are so soft that it will never make much power. Even so, it's still kinda cool.

This just made me happy! LOL. Thank you. Sounds better than my truck!

Probably should have a small hose joining the heads at the back to improve coolant flow. Awesome video and it sounds killer.

I love this kit, putting all the parts together wow it even has a belt tensioner

I love these videos because, at $1,800 USD a pop, they allow me to live vicariously through you and “build” what would essentially be a really, really, really, cool display piece for me.

This is nothing short of amazing! I'm very impressed.

the one way bearings for the starter i remember that causes a lot of friction and didn't let the engine to idle lower. Also those piston rings look kinda tight!

I wonder if the engine is blueprinted as in all the piston and rods are made the same weight to the lightest one I bet you could make that thing rev way quicker. love the videos🤙🏼

What a great little V8, Sounds fantastic. I can see this in a scale Ford Bronco 4wd RC. You did a great job filming the build, well done.

This is soo cool! You should make a mini alternator to keep the glow plugs on.

very impressed by the OHC design. i seem to recall most of these miniature engines being of the flathead variety

These models are amazing, I seriously think with your skills you could make your own from scratch

For those who wonder.. This is a "glow" engine with no ignition, and no lubrication system. Oil is in the fuel.

Some beautiful cars there Mark. Well done. Fletch 👍

This would be a badass way to learn being a mechanic. Smaller versions of the exact same thing to build and tear down for perspective

The packaging on the engine is amazing.

I think if applied to the rc 1/5 it's a brilliant idea, I'm really looking forward to this work.

This sounds so much closer to a full size V8 than I thought it would. This is awesome!

That was wicked!,you could feel the power

This is awesome, I'd love to see you put this in your RC car lol. I wonder what speed it could get up too. 😆 Can't wait to see what you do with it. It DEFINITELY needs a turbo lol

I woul cut off the ends from the exhaust, thread it and then go 2 flow, in an x-pipe, 2 flow again and in one very thin walled muffler Of course on an JohnnyQ90-self made Hot Rod. That would be an awesome video series. Keep it up, love your content. Greetings from Germany

thank you for the detailed guide, it helped me install this soft

Thanks for the amazing videos

I'd really like to see it in an 1/5 muscle car. And what I think it needs is a cosum exhaust system. Would go crazy over a Helmholtz resonator build in.

Impressive, well done! Also things I didn't think I'd want/need an electric screwdriver, torque screwdriver and potentially a ultrasonic cleaner.

during assembly was there a step for cam/valve timing?

Fascinating stuff Johnny!

A real V8 with OHC’s 😎❤️👍🏼

Love the idea for a flat plane crank. Please do that

These are so satisfying to watch and makes me want to assemble my own

Muito bom sabe se tem no brasil este quete para montagem e o valor

Make a flat plane crank for it, and perhaps some increase in flywheel mass. My vote would then be to put it in a car, preferably a monster truck or something equally deserving! Lots of potential for mods with your ability, and tools.😉👍

I'd like to see a realistic 1/5 scale drag car with a 4 linked solid rear axle 2 (powerglide) or 3speed (turbo 400) trans and tube chassis and cage (like some of the rock crawlers)

Sounds like a Cosworth V8 F1 engine of the 60s,love it mate,I might have to invest in one 👍👍

this is sooooo cool, and give me the last pieces for me to understanding how a car motor is working, so interessting and cool, v2, v3, v4, v5, v6, v8 and more and the fact isnt matter how big is the motor, every motor in every height would can move an device like an car or other

Wow! I love these engines! They sound so good! One thing that I’d really want to do is make a “perfect” scaled down engine but I’d need soooo much equipment to do it!

Johnny, I have great respect for your machinist, tool making and engineering skills. I enjoy watching your videos. I have been building turbocharged and supercharged engines for around 35 years now. The amount of time does not mean anything though if you're not learning new important things as you go. I see that you're struggling to get this little v8 engine to want to wind up and make horsepower, and It seems like supercharger or no supercharger you're getting the same results. I think I may be able to help you fix these issues one at a time but just know that fixing certain issues will cause this engine to start turning more rpm and making more power which can lead to even more problems, but that is the fun of make horsepower right! LOL. Not only that, but I will start by saying that cam shafts must have needle bearing or plain bearing support between every cylinder. Since there is no pressurized oil which is a whole another problem I think you have no choice but to use a thinner grease which is synthetic Amsoil and create a splash system up top for now and have new cams made that have a needle journal big enough to slide the cam through the holes to assemble it. Plain bearings are awesome, but they require high oil pressure delivered in the correct unloaded area in a wedge design in order to work. Needle bearings can not handle a lot of shock loads, but they can run with very little oil. So I think your valve spring seat psi and over the nose needs to be increased because without a stable rigid valve train that engine will never come alive. And for now I would leave the exhaust valve size the same, but the intake needs to move air, man! Double the flow on the intake should be doable no problem with a larger intake valve, and the port and runners need to be very carefully designed by someone like Brent Long from Long Machine or Dave Bamber from Bamber Racing Engines. Both these guys are second to none, and they are not builders, they are designers, Inventors, Internal combustion engine gurus and the nicest guys you'll ever meet. Either one could help you more than I can because I am their student, but I would love to see you make your little V8 come to life, and I know for a fact there is so much more there to be had. You haven't seen any of its potential yet. You are the man for the job and very capable, but now it comes down to what must be done to fine tune, like you say. Do not give up, please. Hang in there. I used to run them crazy Unlimited alcohol super stock tractors with an inline 6 cylinder 4.875 bore 5.350 stroke 2.600 intake valve to give you an Idea. 3 turbos two stages intercooler homemade pistons, rods crankshaft head valvtrain manifolds. A lot of work. She made 85psi boost plus and used 4.5 gallons of methanol in 8 seconds. Waterman fuel pump flowing 22gpm at 245psi fuel pressure. Over 4000hp at 6000rpm. Too much fun, my friend.

Wicked sound coming from that little engine!

It's just like a real build. This is sick!!!!

I really wish someone would start making these just a bit bigger, and normal gas powered so we could build go karts to put them in. I would love to have a V8 go kart and lawn mower lol.

I think you can get it running better with a exhaust redesign... those pipes are definitely restricting flow on its bends... And also (something you probably already know): Multi-cylinder engines that size usually have a system to turn on the glow plugs at 30% throttle or lower, just to make the idle more reliable...

That is just badass. Thank you for sharing.

So cool . Even the glow plugs work and are tiny. Unreal. Miniture stuff is very appealing to me

Great video! That engine would be awesome in an RC F1 car, or an RC boat!

I would choose an RC for this engine. It looks good and surprisingly sounds good as well

Man this is awesome. I am so tempted. I would just build a cool stand and use it as a display model I can start up and rev. Has that V8 roar I was not expeting from nitro

Very cool! I say a scale Deuce Coupe, with lakes style headers. You could fit your three speed manual, though it's not to scale. Maybe make the dogs out of metal, (as you were musing), so you could make the whole assembly much smaller.

Awesome engine Johnny. As a fellow 1/4 scale engine owner, keep in mind, Heat does not scale down, how many ounces of water do you have. My build has almost 90 ounces and it does not take to long for the tanks to get HOT.

love it, definetly do the 1/5 scale car tho. BTW; how did you do the belt timing?

I’m equally impressed with the thermo cam app on your phone!

This is an amazing build I wish I could do it myself and I vote for the 1/5 scale

It needs some timing in it. It’s really struggling to run. It would be very impressive if they could design a programmable ignition for these little engines, instead of using glow plugs.

id love to see you put a different performance cam in that thing! maybe custom made?

Had to re-wind video cos at end was looking at twin cam pulleys per head, thinking i didnt see twin cam 16v heads lol, but great model, i want one.

I’m still convinced that theses motors are perfect for teaching anyone how to tear down a actual engine or rebuild one. Even though they might be on the expensive side.

the way those engines stall tells me that there a lot of friction going on that has to be overcome but looks and sounds nice

I think combine it with an arduino and captors to have the oil pressure, the temp of water etc could be very awesome ! Do you think it’s possible an engine as same size running on diesel ?

I'd love to build one of these. Great way to spend a Sat night!

I used to love building these things back when I was prescribed Ritalin as a teenager.

It would be interesting to see a setup where the starter becomes a generator after startup to run other functions of the motor. Like spark plugs, electric fans, and even radio transmitter.

I would love to drop this fantastic V8 into a remote control scale model of a 1968 Ford Mustang fastback! Blue with wide white rally stripes.

Bro your coolant setup is genius!

That's just some otherworldly experience. So oddly satisfying to watch.🤤

Interesting that there's only two bearings per camshaft. I guess since it's lubricated with grease plain bearings wouldn't work up there and there's probably not enough room for sealed ball bearings that would still clear the lobes

Not sure about the single steel piston ring on the aluminium block, but it still looks cool! I could see a couple of simple mods that could make that a real beast!

These kits are amazing!

I would like to know where you get that screwdriver not the electric one but the one that looks like a torque precision it doesn’t let you over tightening and makes that clicking sound
