Large Scale Model V8 Engine - PREVIEW 

Thanks for your opinion! I think that these engines are built very weak on purpose to reduce the work in development and reduce the stress on the parts. That's why all the carbs, intakes and valves I've seen on these china engines are very small. The Conley V8s seemed to be very different quality. Still amazing what they're making now, and it can only improve. Plus the price is already remarkable

It's Chinese after all. I'd be surprised if it was good out of the box.

what you expect for china pos, they build these quick to be just barely working to make money. Its the only reason these exist because they know its money maker per unit sold compared to selling many products for cheaper.

@@paulklasmann1218 I would expect a good running engine for 3000$...and no missing nuts/screws whatsoever...

for an engine this expensive, these problems shouldnt exsist at all. I mean I know that the machining takes a while and the lower production numbers makes economies of scale non excistant, but the quality should be put into these engines to allow for simple assembly and running in no time, there shouldnt be these pretty major quality control issues. I wouldnt want to spend thousands on an engine only for mounting brakets to be re fabricated, cams not even close to functional, screws and shafts that are bent or missing, and the entire thing just isnt built well. With the low production volume and price, I would expect the engine to work flawlessly with no extra work needed on my end, probably test ran to ensure prefection on such an expensive engine, and better CQ to catch these glaring issues. I would love to get one, but even at half the price I wouldnt want this because of the issues, fabricating and machining rerquirements to get this running, and just the lack of any support.

how in the world did you even spot that???? 😦

good catch

@@chiron9536 probably was watching it on a 1000" TV

@@chiron9536 adhd lol. i notice stuff most people miss all the time

I saw that also. Helps to be watching on a big monitor. Seems like there are quite a few quality assurance issues with this model.

or twin turbo

I would test it with an electric turbo

DEFINITELY!!

YEAH

If you look at the other videos, forced induction with these tiny engines is tough. The tolerances and bearings need to be super tight

I thought of a scooter or some sort of motorcycle :P

my Derbi gpr 50 is 50cc and runs 80 km/h easy. so some boost would go well ; P

your moped is a single cylinder twostroke, I doubt this v8 will ever make as much power.

​​@@lucasvanhamburg4937 description says 3.8kW, i had a 4s 50cc moped which reached about 60 kmh on a good day with 2.2kW. Derbi 2s is 6.5kW. So it might be unpractical, but possible. You'd probably have the only v8 moped in the world.

@@HvV8446 wow I didnt know it made 3.8kw, thats totally a usable powerplant for a moped. I think whatever Q90 does with his engine it will be very interesting!

More like 30 thousands.

For the really lucky, there’s only 1 of 3 that work out of the crate.

Yeah, like i understand that they don't want to tune every single engine to run perfectly, I even understand that there might be some minor leaks but that missing nut on rocker arm is just so obvious mistake and selling it like that is just disrespect to customer.

@@Dymitr_Nawrocki Welcome to China.

@@thetruth5232 ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-MTwseJzdmCw.html Pretty much covers it.

Another option is 5w-20. Performs like straight SAE 20 oil at operating temp.

@@patx35 Yeah that would probably work just fine. I just worry that oil being that thick might not be able to get where it needs to go and do what it needs to do. It's also going to cause a lot of drag in the motor.

your assessment of the oil is wrong....the multigrade oil 20w50 has a weight or viscosity of 20 but lubricates like if it was a 50...thanks to the additives....so its still a 20...has the viscosity of a straight 20...with the advantage of protecting like a 50..... for example on modern diesel engines they used 5w30 but now are switching to 0w30...they both lubricate and protect like a 30 but the 0w is much thinner resulting in less friction and more efficiency.

@@MrHBSoftware That's not how it works. 20w50 Multiviscosity oil is designed to have the cold viscosity of 20 weight oil when cold but the hot viscosity of 50 weight oil when hot. Essentially it doesn't thin out as much as a single grade oil as it heats up. This allows It will be thin and flow well when cold yet not be too thin and lose its ability to work properly when hot. Look it up.

@@MrHBSoftware @DoRC is right. Watch Project Farm's videos on oil comparisons for more info, they're extremely well done

i have this moped that is speed limited by a hall effect sensor cutting spark , its a 4 stroke single cyl, would a module like that be able to fool the cdi?

I was just about to say the same thing. Or at least get a few hundred off due too their incompetence and lack of QC.

He never pays for any of these, they get shipped to him free of charge (or even with a fat check) to be featured on his channel in hopes of luring suckers to buy them. This whole channel has become a chinese commercial channel.

This engine would be a cool demonstration system to use a board with the speeduino firmware to better control the ignition, and maybe even add (single point) electronic fuel injection

Was thinking the same thing. A real V8 in one would be awesome

someone many years ago put a conley V8 in his homemade grave digger, it worked very well

Weirdo

Hey Dennis! I tried it, but it didn't solve the problem. Yours sounds fantastic, on point!

tune

@juuso hiltunen Won't happen. These things all run like crap because they just come with carbs to make it idle and rev up a tiny bit. Useless for anything else.

Tbf you Swiss get a better standard of engineering. It’s like that time I bought a Ducati and ruined all other motorcycles for myself. Don’t be me.

What brand you recommend? Does have reasonable price?

@@borivojetravica569 Good question! At the moment I would recommend KPL 632 V8 engine by KPL Perfomance. This engine ist just out of space! The pricing for a new engine is 12'500 US$. Another alternative would be a Jerry Howell's V8 or Gary Conley's V8 on the used market. These are all high-quality motors and when you are lucky you can find one under for a fair price. And no, my homemade V8 isn't for sale 😅

@@danielhunziker3577 one more😁...I am preferred truck 6x6, 8x8 1:4-1:16....way we don't have diesel engine on the market? Is easy to build, longer life...

@@borivojetravica569 Very good question! Diesel model engines used to be very popular in the 70s. However, they were difficult to handle and it felt like it took hours to get them running. Diesel model engines were then replaced by glow igniters with methanol. These were much better to handle and easier to start. That was at the beginning of the 80s. What you mean are classic diesel engines with direct injection. The manufacturability of such small engines is probably not given here.
