The fact that even at a significantly smaller scale, you can still hear that supercharger whine is amazing!
भाई यह कितने की गाड़ी है मुझे चाहिए

not to mention it's a pretty basic/ rudimentary blower

I love the Hellcat name so much because of jokes like this, the name is unforgettable.
🤣😅😂💪
No
Dont give up, the advice everyone is giving is spot on, i got nothing to add, when you get the air fuel n timing right it will all be worth it
Every single time I see a mini V-8 engine on TH-cam I always think when is somebody gonna put that on an RC car. Thank you fulfilling my TH-cam V8 RC car fantasy
I'm a retired automotive technician so take my advice with a grain of salt. When you install something forcing significantly more air into the engine (Supercharger) you immediately need to recalibrate jetting (or injector tune) to increase fuel delivery- especially on the upper half of the rev range. Bogging on combustion engines is a symptom of fuel starvation. Increase fuel delivery incrementally until the bog goes away. Your goal should be to run slightly rich to keep temperatures down and ensure you won't damage the engine. The other thing to think about is the ignition timing which needs to be recalibrated slightly for forced induction. You may need to advance it a touch. Good luck. FYI- a very cool little engine. I wish we had things like this when I was a kid.
The only thing I would add to that is since the oiling system in this engine is the fuel, I'd all a little bit more oil into the methanol to keep temps low, also the timing will be hard to adjust, because the glow plugs at boost tend to overheat and pre-ignite.
Seeing that it is a glow plug engine - I don't think the timing can be altered.
@@MidMadn11118 Glow plug "temperature" can be used as a robust way to adjust timing on a nitro engine.
I thought I was hearing something not right , after reading what you said , I was right with what I was hearing. . . 👍
I heard the bog as well in the intro. Was surprised about what seemed slightly poor throttle response. Generally, I expect a well tuned roots setup to be pretty snappy. But, you do have it backwards on the timing. When you compress the intake charge with a supercharger, or turbocharger, the molecules in the intake charge are closer together and this causes combustion to happen faster. Therefore, you need to retard timing from what it would have been naturally aspirated to prevent detonation. The same is true with nitros, which some would call CHEMICAL supercharging.
It’s going lean at high RPM mate….add more carbs,fuel and air otherwise it’ll run super hot…great video ❤️❤️❤️ adding boost means the engine will need to flow nearly double what it is now…I’ve built real engines with high boost,maybe look at increasing port size and or bigger valves…you got this bud love your work ❤️❤️
Agreed, definitely needs more fuel.
@@paulterhaar4862absolutely my friend
Kelihatanya anda sangat berpengalaman
In bigger engines, bogging down at high RPM usually means too much fuel, doesn't it? Unless everything is getting too hot and it's expanding, causing internal friction? The exhaust looks pretty rich to me, too, but I'm not real familiar with nitro/gas RC cars either, certainly not anything in this caliber.
Likely too much friction at high rpm that the engine struggles to overcome. The blower is probably producing little (if any) added power, while contributing to parasitic losses and heat.
Wow. That's the best sounding RC V8 I have herd so far. Sounds awesome.
It's going to be one of the most amazing rc cars I have ever seen and I raced them for years the bug catcher makes it look amazing great job so far on your build I'm sure you will figure out the fuel problem
DUDE! I have never heard a better sound out of a miniature super…good job!
I never saw a miniature super
You’ve never seen one before this video?
@@ryanryan3473 Nope.
@@cenreaper9127 I've seen small engine compilations, and some have the supercharger, but I'm not sure if they are actually forcing air, or if they're just for show
yeah ok
Everytime you open the throttle it sounds like the supercharger is shouting „VRRROOOÖÖÖMM“ 😂😂😂
You mean it have a swedish accent?
@@sergep1971
I am from Sweden. And yes.. but no. 😁🤣😎👍
I absolutely love how you added the blower. It goes well with muscle cars. Gives it that powerful feel, ya know what I mean?
Good to see you figured out the overfueling issue.
With more air, you need more fuel. Try building a pump and pressure gauge that will give you the right amount of fuel depending on the pressure.
You can have more pump all day but if the carb jetting isn't big enough it will never get the fuel it needs
@sourand jaded thanks for your comment. rather more detailed than mine would have been (even could have been) i just liked the whoop whoop sound of the miniature supercharger! 😃
@@sourandjaded2586the fueling is still an issue beyond just winding the needles out. Traditional automotive carbs suffer in supercharger setups as the vacuum of the blower prevents the power valve from opening under WOT, this is due to it being actuated as the engine vacuum decreases while the supercharger increases carb vacuum as it spins.
These hobby carbs don't have any of the circuitry required to properly fuel this application or make use of boost reference and winded needles will just muddy the throttle resolution elsewhere.
How does forced induction increase your compression ratio? The comp ratio is set by the material properties of the engine components. Do you mean volumetric efficiency? If so it's directly benefitted by forced induction.
A thicker head gasket can reduce the compression ratio which can assist in avoiding detonation. Forced induction enhances your volumetric efficiency provided you can adequately fuel the application. Literally everything hinges on the carbs.
@sourand jaded Only thing I can think of is the carbs aren't designed for that much airflow and are going lean, or, the 2 to 1 feeder can't supply the fuel, might need a separate one for each. You wouldn't think it would need that much here, but who knows.
Other thing is might need different glow plugs, might be blowin these ones out.
It's not a fuel issue it's an air flow issue. The reason you can hear such an audible whine is due to back pressure in the blower case from the blower being so restricted . They made it like that on purpose and the two very small outlets from the blower are clear evidence of that . This blower was made for sound not performance . That's the reason it's bogging it's not getting enough air you can hear that the blower makes less noise at high rpm because the vacuum from the engine is effecting the back pressure in the blower it's being lowered because the engine is trying so hard to get air . If the air outlets were bigger it would breathe better but you wouldn't get the cool blower whine .
No this is badass, it sounds so good
I saw a video where the intake valves were ported and it made a huge difference. Im convinced that if you did something similar combined with the blower and good fuel pressure the top end would come alive
looks and sound really great
Thanks for taking the time to make the video and share it.
Definitely think it’s an issue of tuning, getting a lot more airflow than it was before so it’s running lean, I’m definitely interested in seeing once you have it situated what sort of power it gained from the boost
You need to increase the amount of fuel coming into the carbs to compensate for the increased amount of air coming in from the supercharger. Really cool setup. I am looking to get some of these engines to build and put on display. :)
What is the adress internet site for these engine please?
@lbj in the description
Just found your channel and I'm hooked already. Thanks for the great content mate 👊
That sounds is already awesome, great work as always!
WOW what an awesome project! Can't wait to see how this progresses!
Couldn't have asked for a better sound than that, very impressive!
👆👆Congratulations 🎁 🎉 You’ve been selected to receive GIVEAWAY PACKAGE 📦 Text me 👆👆👆to receive prizes 💝 Thanks for watching🎊🎉🎉
dude, this is amazing! please continue the saga to make this RC.
Would love to see the before and after a full tune power and torque difference. Would be nice to see how much boost its creating through the rev range.
Sounds like the mixture is leaning out too much, so you definitely need to add more fuel. Maybe extend one of the existing pulleys outward, and then you can make your own supercharger gearing? Definitely excited to see where this goes. I remember seeing some 'turbo' keychains which were sealed, so maybe you could have a look at twincharging it? Just a thought :p
You can watch keith57000's v10 engine build compilation to see a nicely built supercharger which isnt straight. Also to mention his v10 engine also struggles in full throthle. I figured it can be related to supercharger after you experienced the same problem. NICE video. Please keep up the good work!
Wow. Honestly I haven’t seen a better and more supportive/ helpful/ informative comment section. Keep it up y’all 💪🏽💪🏽
Amazing! Very nice little engine that you'll probably get more and more out of. Can't wait! Good luck👍
It runs lean on WOT, we can see the fuel stopping to circulate in the line at WOT, the carbs are not designed to be fed high pressure air from the supercharger is my guess. Awesome work. The sound is so nice.
It's a draw through set up, the supercharger is actually sucking air (and fuel) out of the carbs and the pushing it into the engine, I suspect it's actually running rich up top due to the suction from the supercharger pulling too much fuel through, it has more of a rich bog sound to it
@@JshDav But i saw the fuel stopping to flow in the clear tube at high rpm. Also try to elevate your fuel tank.
Needs a lawnmower carb!
Please don't give up on this!! Your videos are awesome!! You skills are even better!! As many have stated you need more fuel. You can't add one without the other. Porting and bigger valves, Maybe even bigger cam with more duration and lift and/or lighter rotaing assembly would make her super snappie. With the tools you have all could be easily accomplished!!! I'm a turbo guy myself but this is pretty sweet. Excited to see whats next!! 👀
Very cool to have a supercharger on a mini V-8! After you get it tuned, dyno numbers please! Keep up the awesome work!
It’s going to be a little beast!! I can’t wait to see the final results.
Have to love the sound of a roots style blower ..😎
I definitely think you should keep the super charger and make this look like an old-school 60s/70s style car. Like a Cuda, Chevell, Road Runner, Camero, etc. Or even a hot rod. This is soo cool, you'll get it figured out. I think the glow plugs can't keep up with the upgrade. Or it just needs some tuning. Either way, good luck bud, I can't wait to see what you make out of this. I wish they had these when I was big into RC. Lol. But I also don't have the knowledge that you have lol.
For a miniature engine it sounds awesome with a super charger. Great job so far can't wait for more video's. ❤🇨🇦
Now we live in era when rc car can sound better than an actual car. What a nicely done job! The sound is everything!😤😤😤🔥🔥🔥
What's not to love about a supercharger of any size? Are you planning to replace the water pump shaft with a idler style? Not that it would make a lot of difference in the early going but the gear side of shaft against the smooth belt can cause a wild amount of drag in some cases. lots of fun watching , Thanks
Really cool build!
Regarding the issues with WOT performance, there are a few things from the (big) car world that might help: Spark plug gap - When you up the boost level you normally need to close down the spark plug gap to get effective combustion. Not sure how this would work with glow plugs, do they make them with bigger or hotter elements? Also boosted motors normally run less timing advance vs NA motors, since glow plugs are always you can't adjust this but I think you would get similar results by adjusting the octane of the fuel.
It's a bummer they made the pully on the supercharger so small, would have been a easy way to get more boost. You could create an additional gear box between the belt and the supercharger, to give you more ratios to play with. CNC project time!
Yep, glow plugs come in different temperatures. High compression engines need hotter plugs usually.
This is one of the coolest things I think I've ever seen. Awesome
Man! that charger sounds sooo freakng good! definitely fuel starved on the top end. on a full sized engine you would re-jet bigger but on this, maybe the siphon feed isn't enough? maybe a pump/fuel loop system like fuel injection? or some type of pulse pump linked to boost pressure? Also with boost on a full sized engine, you would advance the timing a bit with boost. I'm thinking that may be a tuning option here as well. I genuinely want to see the charger work on this build..
Coolest video on TH-cam. Yeah it's definitely running to lean. The little 3.3 nitro engine I had when it was running lean it will cut out like that. If you can open it up produce more fuel, you will see a massive improvement. Plus it also could be pulley system isn't the right diameter to feed the fuel/ air to the engine that's required for an improvement over N/A
That is sick it looks and sounds so bad ass. A little tuning and fuel and this thing will fly!
This is awesome. I love it. I also love the engine sounding like a man screaming when revved up.
Wow, that sounds cool.
sounds awesome! it definitely looked like the belt was dragging on that water pump cover that you modified though... looked very tight there. i think you might need more fuel for the added air... im excited to see your version!
But how do you think he can add more fuel?
@@justanotherguy469 maybe bigger carbs, or bore them out? im betting its lack of fuel. with the fullsize cars, if you add forced induction, you have to add bigger injectors for more fuel, otherwise you'll lean the engine out and blow it up.
WoW, I just found you! Dude, you're the coolest, craziest guy ever! I love your videos! You are amazing! Greetings from Austria
Nicely done 👉🤜. Thanks for sharing!
WOW! That sounded truly awesome - I think some electronic engine management, tiny injectors (If they can be made or bought) and a pressurised fuel rail could be a good next step if it can all fit in the rc car.. what scale is it? 1/5th?
Keep up the good entertaining work that you do. All the best from the UK.
Agree, but I would love to see how that Boost's on "HHO" the skill this guy has, he could make Tiny Electrolysis device, see how that Boost's.
I love to see all his YT Project's, great maker, think all his builds are great.
Running on HHO, would be super cool.
Yeah its leaning out the top end.
I would tune the HSN on the carbs to give it more juice.
Half a turn out on each. (Counter clockwise)
The low speed needle seems a tad rich and your idle could do with being slightly higher.
Turn (clockwise) 1/8th
But as a first start that went well.
It also seems like a backpressure issue if I'm being honest.
30% is actually pretty good stuff, plenty of punch, I used to run byron in my savage and it loved that stuff.
That bogging out issue definitely sounds like a fuelling issue crossed with backpressure.
Zoomies! Top fuel R/C
Dude ,, you are way into your rc cars. That is awesome good job sir
Wow I have been on a 16year vacation you are really inspiring
I was only waiting for that
It's awesome!
Definitely could use a better drive system tho. Maybe a separate belt running the supercharger? You could technically install a pulley that attaches to one of existing ones on the engine, an extension of sorts. You keep the original belt track and direction of the water pump this way, and get to use your own gearing ratio for the supercharger. And I think tweaking the gearing ratio could help with the power, throttle response, bogging, etc.
Keep doing what you do, you're doing an excellent job!
The supercharger is trying to force air through the same size ports as it did when it was naturally aspirated. Open up the intake ports to allow the air to flow into the cylinder without restriction. Amazing build and great video, hope to see update.
I have a single cylinder nitro engine it rips.
This is a cool build!
I really wanna see that Dyno brought out for this na, and out of the box supercharged, then I wanna see you millout the top of that blower and make your own intake plate with 4 big carbs. This things lean up top and blowers generally need a 1.5-3:1 intake to outlet ratio. You might get two carbs to flow the fuel if you drill the bore for the needle valve and anyother restriction in the fuel.
I don't think the belt has anything to do with it running badly either. Iv built lots of fast big stuff including a tiny compound turbo 155cc near 100whp. I don't think the belts the best but I don't think it's the big problem it's definitely lean.
sounds like it needs more fuel, but holy crap this is wondeful
Dude that thing sounds amazing, im so glad to see it working like that

Congratulations 🎉🎊..
such crazy advanced small scale builds, its quite incredible
dude you need to help donut media!!!!!!
Wait, is this the same one that Nolan from Donut Media is trying to build?
Hey, try having the throttle body on the supercharger open in the opposite direction, as in instead of the top portion opening out, have the top portion opening inward.
That’s how throttle body’s normally work for a blower style supercharger works. Just a thought and I really hope your able to read this comment.
i have watched this guy for years and every video of this engine i think it is the last of it then he makes it better he never disappoints me to amaze me
Cool Toy!
I only had a cox pt - 19
Thanks for sharing.
I am just amazed at the craftsmanship 😊
That sounds sooo frickin cool! Heck yeah dude
This thing sounds awesome. So cool. I might have to build so.ething like this in the future. Going to take practice cause your skills are next level. I'd love to see the power it makes.
Appreciated the supercharger air blowing demo
Can't wait to see more! 👍
Did I see air bubbles in the fuel line? That will give you fuel pressure problems all day. Definitely lean on the top end, that hanging throttle is a dead giveaway. Sounds so good. Always impressed with your builds
It just seems like that engine needs so much more air than those little tiny carburetors. Seems like it’s choking it out. But that is absolutely awesome. I’d like to see what bigger carbs and intake holes would do for how it runs.
Bro,that is SUPER SICK!!!!!!!!
in the 1990's there was a 20cc 4 stroke OS engine with Supercharger. that one worked really well. I used to have that engine in my F3A competition airplane
That mini supercharger whine is great 👍
Sounds amazing!
Dude got some insane skills
Awesome Work and Video!
Johnny ... speak ,, move lips .. make sounds ,, practice , these silent picture book videos deserve so much more !
bro i thought my ears were ringing bc i have earphones but great video man ❤️❤️
This sounds amazing
Thats pretty sick! Back a long time ago when I used to race a t max truck I put a supercharger on a nitro motor I had in it. I could never get it to run right. It forced so much air I couldn't get it rich enough to quit leaning out. It looked cool as crap though! It wasn't a screw style more like a procharger look. Very cool my friend.
Wow dude that sounds awesome ❤❤
Unbelievably Awesome
That is just plain Badass!!
Superchargers are the most awesome sound 👍🏻👏👏
can’t wait to see the finished product! is it possible that you could make your own straight pipes for it?
Sounds awesome 😎👍
The bog seems to be rpm related, not just throttle position. Which indicates fuel starvation. With a full scale engine, this is fixed by adding a boost referenced fuel pressure regulator. This raises fuel pressure to increase fuel delivery as boost increases. Otherwise, the carbs will be either overly rich at low boost/part throttle, or overly lean at higher boost/full throttle/high rpm. Either one causes a bog. The trick is, applying that to this small scale version. The creator was smart and talented enough to build this incredible engine, I dare say he already knows everything I just typed, but applying it brings up all sorts of issues and requires quite a bit of knowledge. I'm sure the creator will end up getting it tuned right and I can't wait to see the final product!
that is slicker than snot on a doorknob, neat build
Get this thing on road.🔥🔥
The internet was made for this ❤
How sweet the charger Sound is!!! Very very nice fazination work you made,fantastic big Master pice!! Respect from Germany the mother of all gasoline engine!!😉 sorry for my bad english best wish Reiner from Germany
That's amazing! it actually sounds like a real supercharged V8, for such a small thing
Thats a nice v8 Hemini
work of art! would have been nice if we could see the car running.
This is too cool
Seems like there is a great deal of friction in the supercharger itself also - maybe some bearings or self lubricating bushings?
The supercharger made my soul happy! This would make a great pencil sharpener, or handheld toiler paper butt buffer!
👆Thanks for watching ❣️

Congratulations 🎉🎊⬆️⬆️
The sound of the air being sucked into that blower is PURE MAGIC! I had a moment LOL 😍🤭😅😆😄🥰
What an absolute beast. And cheers for showing the internal workings of the supercharger too, it's quite lovely and therapeutic seeing it. Why does it "bog" at full throttle? Injectors not up to the task or belt slipping?
Yep, needs some more fuel, can't ever just upgrade one thing
Amazing stuff
