Yyyessssss

Yes or a bit bigger of a turbo

XmX not a turbo

I hope it put it on the V4

No u gotta put it on the see through head engine

You would have to use tight fitting stators to increase efficiency to ever hope building any pressure with it.

Can you please solve the problem of people saying "my guy" also that would be great.

@@crimescene25 no

That is a micro fart... and fart box

He could try one from a drill?

@@mealex303 No he would need one rated for the crazy high RPM he is using. It would be difficult to find

Agreed, also would balance the loading on the gears, since they are more constrained. The radial loading is likely what's destroying that.

@@mealex303 yeah, but a drill gearbox is probably better for torque than speed. Also anything that would be economical to strip for parts would have ABS gears most likely.

@@mealex303 Those are quite a bit larger and the recent ones I've seen use plastic housings that I doubt would hold up to 150K++ RPM.

he needs to add a stator to build up pressure, same as the centrifugal compressors on jet engines. You try and research them, they serve the same purpose as stators in axial compressors. agentjayz has videos on his channel that have explained the significance of stators.

@clicking on trees Dude stfu like you would even try to do this shit and figure out everything. Hes trying and its not a tutorial sp go take you stinky comments to someother video

@clicking on trees, buddy, politely fuck off. Nobody cares about that.

@clicking on trees he's just a troll relax, it's obvious.

@clicking on trees By watching his design & build skills, one can clearly see this guy has a lot of knowledge about materials & engineering. I don't think he started this thinking, "Brass is SO STRONG - I can overload it, and it will be fine!" I think it was more along the lines of, "How could I make this work - even with brass?" Also, there are other material properties of brass that makes it a good material to use, even in high speed cases. Things like friction and bearings come to mind. I think that He was just trying to make it work, and maybe the brass was there to be soft enough to "deform around the other gear teeth," maybe to compensate for any imperfections at this tiny size? What do you think? I don't think he would go to this much trouble for click bait. So many other things he has built have worked really well. Have a good one.👍

No but its cooller than yours

nah but it's cooler than your garbage

Rock en roll will never die,👍👍

What are you talking about? That brass gear died screaming in the dark. Its life was basically a horror movie.

Case hardened steel or even a nickle super alloy would do the trick.

I'm not sure any metal will really withstand 150K+ RPM for very long. That's some insane speed.

@Kyle But they don't have gears, they ride an oil film or use lubricated ball bearings. Spining is different from grinding gears.

brass gears,,, yea" maybe for the "Lightnin"speed of an analogue wall clock,,

@@AverageCarGuy especially since all the gears are so fine

also weird flex but ok.....

@@crimescene25 How is it a weird flex to be interested in how 5-axis cam differs from the 3-axis I'm used to?

@@crimescene25 Why do you get salty about someone wanting to know about what goes into these projects?

then he can build a little Detroit Diesel engine to go with it

J. A. G. I cant wait for the day when he builds a miniature 4-53

Maybe a lil Cummins

I've heard lots of full sized roots superchargers, I'm very curious what a mini one would sounds like!

I just want to add, I use speech to text a lot, I didn't proofread what I wrote, so I apologize for looking like much more of a moron than I really am. LOL

The issue is with the scale, as centrifugal requires having air *mass* moving for it to do its thing. Really small turbines only seem to work ok with liquids or gases that are already compressed to a high level to begin with.

The other problem is the low tip speed of the blades due to how small the impeller is. If you cant get enough velocity at the outer portions of the impeller, it will never make any real boost.

The noise you hear is actually the gearbox drive, not the impellers. The sound the impellers make is eaten by the engine.

My thoughts exactly. While I’m certainly no expert, such high RPMs no doubt require near perfect balance. Something you’ll never achieve with a Dremel tool.

Well, you can, but you must balance it. And you can balance with dremel and proper tools. Moreover those bearings are not rated for these rpms and ceramic would work much better. No cooling made to the gearbox as well

Same with the wife

@@Pogohontas. haha lol

No just grossly overpowered.

@@darkracer1252 why are you here?

@@samo4648 google recommending bullshit video's made by inferior people

Even tho there is no contact betwen parts using fluid viscosity as a mean to transfer force the gear box can still be destroyed if run on extreme conditions or not be efective at all in some conditions

@@bernardoalbano1816 yes, that is true, everything has a breaking point, however the use of this specific type of transmissions in this specific scenario has been proven efficient and effective. So I concur to your point in theory but I fail to see how it applies here

If he goes automotive style downscaled it would be very hard to do but there are some super basic designed positive displacement blowers in the industrial world that are extremely basic.

Aaron Rembert example?

I second this. Material composition is also a primary concern once you start pushing tolerances including temperature. And five to six figure RPM speeds is nothing to slouch at. With that speed, gears would start hitting speeds where material composition would become a huge factor as gears rotate and heat up themselves along with surrounding pieces towards points of expansion or breakdown/torsion max and then breaks happen along stress points like the gear teeth. Brass is a rather flimsy material to use if you want to tolerate heat because it expands at rather lower temperatures than other metals which is one of the reasons why it's used for casing of ammunition. Steel would've been a better material choice, titanium if he has it on hand or a hard aluminum like 7170.

@@AM-dc7pv wiki a G-lader supercharger. I think it would be easier to machine and uses flat teflon strips to seal the the compresion chamber.

The problem is that it isn't compressing the air, a lot of airflow is good, but it's pointless if it's not compressed, the denser air is where you make the power

@@LordPrecision Yea that Russian fella is great I love the video with the turbo jet mounted to a road bike!

kzfaq.info/get/bejne/mr92jL1ezJ3KqnU.html

MR/TROLL I have to look for it. I’ve seen the turbine videos where you have to used compressed air but not a self sustaining fuel powered model

dont worry, when you got the interest.. thats all to it.. i was about the same where you are now a few years ago. i dont own a cnc.. but i do have my own milling machine and a metal lathe. after getting used to milling and lathe work i feel confident that i can do this 2, t i realize that my limitation is just not having a cnc mill and nothing els..

Colin Furze made one out of a trash can and a car's turbo.

Lol

ASMR with JohnnyQ90's hammer

@@MrPnew1 good one .

Centrifugal, Procharger is a brand

Draw though setups (carb pre charger) are easier to get running, but are not very safe in full size applications as the fuel also gets compressed the whole journey to the engine, which turns your entire intake system a potential bomb if a backfire occurs, unless a pressure release fail safe is used, & as such, they aren't good to use with intercoolers, although I have seen aftercoolers used with this setup. Blow through setups (carb post charger) are tricky in that you need to pressurise the float bowl (or fuel metering block) to equalise the boost pressure thus to allow fuel delivery. The benefits are that only air is compressed through the intake tract, making intercooling more viable & safer with the fuel added closer to the engine. Model engine carbs generally don't use float bowls so the fuel tank itself would need more pressure than the usual exhaust pressure used to push the fuel through the carb jet, like a boost bleed line to the tank. EFI solved these problems in full size, but we're probably some way off seeing that in RC applications, although probably not that far off!

He actually put in his first videos on this venture is that he'll be doing a draw-through set up, cause it's too small for anything else

@asshat Jackson That's a valid point you made, perhaps the tiny bearings he used on the pocket turbojet would do the trick. Sorry I don't know how to put links in comments, but you can search his channel. It was from 7 years ago so will be well down the list of vids.

^ What he said.

arent turbochargers just another type of supercharger? meaning you can call turbos superchargers but not the other way around

@@mobbdeep615 No, turbochargers use the exhaust of the engine to shove more air into the intake and superchargers use the power of the engine and are driven by shaft or belt to shove more air into the intake.

When he says glow fuel I'm assuming he means RC nitromethane mixtures. For those fuels the incorporated lubricant is only mineral oil, which has no film strength and would not handle high pressures and soft metals of the small surface area gears.

No chance, a drill gearbox is made to turn 20-25k rpms from a motor into usable 500-2500 rpms at the chuck, and its big and bulky to take 70-80nm torque. you want the exact opposite, small, light, and it doesn't need to take a lot of torque but it needs to be able to turn that same 20-25k rpm into 150+k rpm, and a drill gearbox just isn't made for that speed, infact I don't know any existing gearbox that is, at this scale...

And why wouldn't it? He got 1.5 psi in the last video. With further design he could get a lot more too

Cody Evans It’s an open system unlike an actual engine so the air would just go right out the open end and not make any boost pressure.

@@Chevsilverado hes trying to put it on a valved engine itll work. .5 psi more then atmosphere will make a difference on a 2cc engine

@@stevend4544 Yeah I think I was saying more like without an engine in front of it it wont make any "boost". Idk what I meant by my last comment.

@@stevend4544 I don't know if .5-1 psi of boost would make any more difference on this than a car engine. It has a much much smaller cylinder volume so boosing to .5 a psi would only add like 1/15th more volume of air meaning you could generally only use 1/15th more fuel than before. Theoretically it would make only 1/15th more power than it would before. For example it isn't very unheard of to have atmospheric pressure of around 15.2-.3 psi at sea level in certain conditions.

I'm assuming there's more mechanical resistance in a screw compressor, and since the engine doesn't make much power it can't drive one very well

wouldnt waste my time with titanium, far too weak for the cost

Not for nothing . he learned.we learned.
