That's not the main issue at all here...The reason for all the heat in the block is...is he let it run at absolute max throttle knocking its nuts off for a prolonged time till the fuel tank was completely empty, did not let it idle at all. The result is that the water pump is driven by the belt on the front, no engine RPM = NO coolant flow! hence the lines being hot close to the engine. completely the wrong way to look after an engine.

I wouldn’t run them longer than a few minutes so it’s a good thing the fuel tank is so small!!! When putting mine together I lubricated the short block with some Q tips dipped lightly in Royal Purple that I use in my cars and trucks. This at least gives it a bit of a coating. After some thought I decided to use a five weight that I run in my turbocharged four banger performance engines. I felt anything more would result in hydrostatic failure of the lower engine internals because of the micro tolerances in theses mini monsters. As far as the Cylinder Heads, Valves and pistons Rings are concerned they should be well lubricated fine for the first three to five minutes from the grease. It will melt quickly and coat well! But anymore than four or five minutes I would probably suggest checking it once the entire engine has been given a chance to cool before taking off anything more than the Valve Covers!

[@frankhamilton8257]

FYI, there's a possibility that you'll break one of those exhaust valves if you run this engine for an extended period of time without an exhaust system especially at high RPM. That's why I recommended running zoomies to get the sound you want. Under "real world" circumstances, an exhaust system is there to provide the proper back pressure to enable scavenging of the spent exhaust gases. An exhaust system will also isolate the exhaust valves from being overexposed to O2, which will eventually oxidize them and crystallize their metal composite, making them potentially brittle. You could even put small balls into the ends of the zoomies to prevent water condensation from entering them during or after cool down.

[@WarpedYT]

Thanks! Those are really great details, those are things not many people think about but you're absolutely correct. For sure I am going to make a proper exhaust, I just ran it without the exhaust to see if it can actually get louder or is it like an engine Port size issue... Thanks !

[@Mrshotshell]

Backpressure is never a good thing. You will have more scavenging and make more power with less back pressure in almost every situation

[@frankhamilton8257]

@@Mrshotshell You obviously don't understand the concept. There's a reason every engine has an exhaust system and it has nothing to do with back pressure or noise. An exhaust system, whether it's zoomies (which effectively produces little or no back pressure) or otherwise, is not just there to direct exhaust gas to be dumped out at some point rear of the driver. From an engine perspective (all other issues aside) an exhaust system is ideally designed to "tune" the air flow as it travels through the engine (particularly in an engine with normal induction), and while doing so, provides a certain level of protection to the exhaust valves from being exposed to ambient air, which will ultimately weaken or fatigue the alloys in the metal.

[@Mrshotshell]

@@frankhamilton8257 I never disagreed with that part at all, just the part about needing backpressure

[@nerd1000ify]

​@@frankhamilton8257 My understanding is that the issue with no headers and the valves is thermal shock, i.e. cold air hitting the 800+ degrees C valve cools it very rapidly, over time this can cause cracks to grow in the valve until it breaks. Should not be a serious issue for such a small motor, smaller valves generally don't get as hot because they have more area to conduct heat to the head relative to the amount of heat they absorb. Also glowmotors run on methanol with a hefty dose of oil (usually 20% or so), which naturally burns a lot cooler than gasoline. More broadly, I suspect that this is an engine specific issue. Many WW2 fighters had 'stub' exhausts, the 'header' if you can call it that was no more than a short nozzle that directed the exhaust flow backwards as it came out of the ports on each cylinder (for bonus jet thrust!). These would surely be candidates for the thermal shocking issue, but on the contrary most of them had more trouble with burnt valves than cracked ones, leading to the use of sodium cooled valves, stellite valve seats, etc.

[@jeffm4284]

Been a while since I wrenched, but sounds & looks like advancing the timing a bit, if possible, would help at the higher end. It was spitting a ton of fuel after you clipped the headers, so you reduced the back pressure to force secondary burn. Maybe a slight tweak of advancement would allow a more complete burn.

[@tomrandall4871]

I believe that extra fuel is caster oil and is how the engine gets it's lubricant into the cylinders. Usually these engines are glow plugs and are designed to already run advanced. Hence the nitro / caster oil mixture in the fuel.

@@eljaibas16 I wouldn't have approved such a crappy engine system to be taken to production... I mean, how is this supposed to compete against a brushless motor.. let's not even talk about price differences.. a premium brushless motor is about $200 bucks.. 8 times cheaper, and 20 times cleaner. This engine needs: *Proper Ignition System with coil box *Real sparkplugs *Crankshaft position sensor linked to ignition computer to tell the sparkplugs when to fire. *Oil pump to bring oil to the head. *Piston Ring sets to increase compression and something extra but really nice: *a hydraulic torque converter to be able to use combustion rc engines in rock crawlers... centrifugal clutches suck at low rpms.

@@P_double_H Agree, for that kind of money it should have a real ignition and lubrication system, expensive toy beside it takes a lot of fuel, awesome tough

This made my day thank you

[@shannonsisk]

This is really cool. However it blows my mind that there is enough demand for these to sustain a business, even though you can buy a REAL engine for much less. Still very cool.

[@christiansanden8005]

Yes I am wondering to, 2 grand is a lot of money for that toy

[@TheTonyMcD]

That thing is adorable!

Has Biden affected the price of Nitro ? lol

While this V8 engine is small it is by no means the smallest. If you visit the Craftsmanship Museum in Carlsbad, CA you can see V8s that are quite a bit smaller as well as V12 engines that are also smaller.

[@FaisalReacts]

looks like a full original size V8 engine 👍

[@dkimcg]

So freaking awesome! Next up, a mini V12 with twin turbos?

A set of zoomie headers would be 😎 cool! Crazy how much juice that thing consumes.

somebody get this guy a mini crank dyno🤣🤣 All of these tiny engines, I wish we knew the power output 👍🏾 love the vids bro

[@WarpedYT]

I've actually had the parts on my shelf to build one for like a year already, I'm just really behind on my projects right now

[@Mike_Stanford]

@@WarpedYT ha, I definitely understand that one! I'm sure making an accurate and precise one takes a few days of metering and connections and everything.. hopefully you can be the first to make The world's smallest dynamometer 🤣💪🏾

Amazing nice thank you for the video👍

[@RA31A]

There is some really fine print way way down in the advertisement page that says most components have to be purchased separately. Is this true? What actually comes with the engine and can it be run as is?????

[@ryanreedgibson]

Your channel is sofa king cool!

[@spire4101]

Now I want to see this in a bad ass rc truck.

[@BolonaJoe]

you need to be selling those brackets you made to hold the engine on your website. great add-on

[@DJscustommusic]

its my dream to run all the mini engine you own on many different fuel with you in person just to experience it in person and im your biggest fan ive wtatched almost all your videos.
