  • Both ports are open on these motors t the same time yes u do see alil boost from the rb supercharger its less 1/4 of a pound but all the extra air and fuel blows thru I've done my homework before I even said anything but id also like to welcome u to use my rb supercharger and my rc to see if u can notices any change at all other then a lean topend

  • @highvoltagefeathers seen u know what I do for a living maybe ya would like me to tune ur motors? All I do is build engines... with superchargers turbo changed or what ever high perfomace motors for 1:1 cars and truck comeover ill show ya how i tune my 351 ho I just built

  • Rb supercharger does nothing for these motors... I bought one just to see what they did* if anything only thing I did notice is that my nitro motor leans way out in upper rpm and if I fattin it up to elimitate this it just bogs out

  • @kylet8020 you don't know how to tune it. Boost can and will do wonders with any two stroke engine if applied correctly.

  • not sure if you own the car with the RB charger on it, and i was just wondering do you notice a difference with it, because i did the same thing just putting a non working EDF plane fan between my air filter and carb inlet. the only difference from what i did is that RB's connect's to the fly wheel but my setup would be just as good because the carb is sucking in air causing the EDF fan to spin creating the "turbo/supercharger" effect of forcing air into the motor.

  • first time ive seen an air filter on rc looks like someone really knows his combustion engines

  • @biggunzcdb i have to admit that comment makes you sound retarded..lol all R/C cars SHOULD hav an air filter if your doesnt then your a redneck.

  • @midnightneonmatt ive seen more without than with tiny particulates act like abbrasives at high rpms but since your so fucking smart you already know that, well know this i dont have rc cars i build real engines and was just commenting on how many dumbasses dont run a filter rc or fullsize so fuck you go play with your toys you wise ass bitch and if your ever in savannah and want to continue this discussion on some mats with your neck getting choked hit me up

  • @biggunzcdb oh ok well there Mr.master engine builder while you do that i build rocket engines for NASA.......dude go blow your horn somewhere else i dont give a crap what you do for a living.

  • Comment removed

  • @midnightneonmatt the funny thing is this isnt even your video and i wasnt talking to you you might talk mad shit at NASA but in the real world youll just get the shit beat out of you

  • from intense speed of piston and your finger response due to with increase of air or gas flow the chamber never has a chance to close for complete combustion in two stoke motors, therefore creating exsessive rich mixture that cannot be fully combusted, lotta gas dumped out the muffler.

  • amazing cars my friends

  • COOL !

    

  • who ever said forced induction doesnt work on a 2stroke needs to go back to school and study physics if that were the case the engine would not run both ports are never open at the same time either there positioned so this doesnt happen

  • @l3thal35 study physics? You need to study some blue prints. These 2-stroke RC nitro engines have the exhaust port and intake port positioned at SLIGHTY different heights on the sleeve. Which means, they ARE open at the same time for most of the intake stroke. What makes a 2 stroke run properly is the tuned pulse from a muffler, ie: gases forced back to the combustion chamber to stop the intake mix from escaping. the Supercharger makes this system ineffective by over powering the pulse

  • @l3thal35 study physics? you need to study some blueprints these 2stroke rc engines have the exhaust and intake ports at SLIGHTLY different heights on the sleeve which means both are open for MOST of the intake stroke. what makes these engines work is the tuned pulse from the muffler. ie exhaust gases forced back towards the combustion chamber to stop the intake mix from escaping. the supercharger makes this system ineffective by overpowering the pulse and driving the mix out making a lean run

  • @l3thal35 LOL, learn how a 2 stroke engine works, or go play with your hotwheels. ffs noobs these days. :/

  • It seems to me that superchargers should work just fine on a nitro rc engine. Both valves are not open at the same time, as the piston travels up for the compression stroke it creates a vacuum in the crankcase as the piston reaches tdc the rotary valve on the crankshaft opens and sucks in fuel from the carb. As the piston comes down it the rotary valve closes and the piston moving down pressurizes the air fuel mixture and once it passes the channel valve in the cylinder it shoots the compressed

  • anyway very very nice model thums up!

  • The only thing it does is some scavenging so the comustion chamber is 100% of exhaust gasses maybe a 1% power increase if you're lucky.

  • @tankjr85 superchargers dont work on 2t nitro motors, they wont hold tune, produce less power severely decrease engine life

  • an expansion chamber would do far more for performance than trying to supercharge it

  • Are there ANY videos showing these cars, um, run???

  • forced induction does indeed work with a 2 stroke engine, but it does not work as efficiently as it would with a 4 stroke....

    no ppl stop arguing over random bs...

  • @lopikoh what are you freaking Retarded a super charger removes smoke are .. are you serious dude a supercharger has two rotating propeller type things inside of it that spin interlocking with each other so they force air down into the intake manifold.

  • more air flow more gas being pulled into the head wich equals slower is what you guys are saying...??????

  • Hmmmmm.... The thing that a supercharger does is to remove the smoke produced from the "explosion" in the engine not pumping air in it... This a loss of money and you are destroying your engine like that..

  • @lopikoh Uh I think you need to go do some research.. SuperChargers pump additional air into an engine, providing more air for bigger exlposions.. They don't remove smoke from anything..

  • @lopikoh Wow...talk about not having a clue. LOL

  • @lopikoh you sir are an idiot....

  • Aussies!!

  • i have a Ken doll that would absolutley LOVE this

  • @Littlemac181 Why are you playing with Ken dolls?

  • is the one at 0:31 a redcat motor

  • @300exkx8597cobrasvt I think that is a NovaRossi on-road engine..

  • are those custom made or i can find it at my hoby store ?

  • regardless....its interesting and it looks cool

  • What a pointless video. video of a static display? I'd rather hi res pictures.

  • the chargers do work, people say they dont because it blows through the exhaust port but the increase in atmospheric pressure actually pushes a higher volume of air and fuel into the cylinder before the valve closes, so SUCK ON THAT RETARDS

  • @redneckfulltime these motors don't have valves...

  • stop hating everyone, its their money, their hobby, their cars, so dont hate, if it so boring DONT watch and go watch some rice or something !

  • i think u needa girlfriend 

  • well ridermike221 i supose u know all this cause u put one on your rc or have previously owned on but i doubt thats the case im thinking u watched squirells video well u know what they say about shit on the internet

  • imagine if there was an operating one with a twinscrew supercharger that would be fucking amazing

  • Idk what i just saw,but they look fast and expensive as fuck lol

  • alright you under age idiots the supercharger is not made to provide boost on 2 stroke engines it is suposed to remove burnt fuel from the engine faster and if your not an idiot you would know how to set one up ive had mine on the same engine for 6 years and it works just fine i noticed a difference instantly so if you say they dont work then dont buy one obviously you just cant grasp the concept of how you can benifit from the supercharger i supose your going to say nitrous oxide doesnt work.

  • @jasonhallman1 ur fucking stupid. superchargers dont work for jack shit on an rc nitro engine. they cook your engine at 300+ degrees becuz it just shoves a majority of tht air fuel mixture right out the exhaust

  • is that a picco 7 port?

  • i thought they were gonna run them :'(,fuck this video.

  • Why is everyone talking about their waist? Is this a jenny craig promo? If so why isn't it titled so?:)

  • dose the supercharger make a big change ?

    and will i be albe to use one in my buggy ?

  • @JORDANBORNTORACE they add no power at all, it does exactly the same as leaning your high speed needle.

  • 2 strokes dont have valves that seal the combustion chamber off. When the piston is at bottom dead center, both the intake and exhaust ports are open, so boost can not be created. Boost would simply push out through the exhaust port, maintaining ambient pressure inside the engine. Sorry, WAIST OF MONEY!!!

  • @ArtyHarvy nice spelling daft cunt

  • @89rmurray So angry!!!??? That shit aint healthy. Just so everyone is aware... I was refering to the supercharger being a waste of money. Not the hobby.

  • @ArtyHarvy not angry matey. i just swear a hell of a lot and take the piss

  • @ArtyHarvy

    The ports in a two stroke are not at the same degree of the piston// some boost IS created and it flushes out the exhaust fumes allot better.. it's deffo NOT a waist of money. it has some purpose.. not as much as on a four stroke but still a bit.

  • Too bad a supercharger kills a 2 stroke motor

  • its a two stroke motor your basically helping push the exaust out the motor put that on a 4 stroke and you have increased compresson thus creating more hp. but in this day and age everybody wants to make money off of stupid things to make others look cool. all you have to do is paint the car some highliter color and put flames on it, wat is that 10 miles faster by perspective haha

  • Where did u get a nitro blower?!?!?!?!?

  • @donvitolover182 they make them with useing some pipe or left over crap

  • @donvitolover182 dont waist your money on them the make your car run like shit and you blow through glow plugs

  • did i see a plastic spur gear on the first car?.....

  • @connell256 lolll

  • A properly set electric dragster should go very fast,faster then a fuel motor.

  • Well expensive or not, it's better to have a hobby than being a criminal...

  • i hope you realise that supercharger does the exact same thing as leaning out your HSN

  • @crzygutrsnobrdr not quite, your not far off though. it pushes air into the cylinder and creates the effect of leanin the hsn by breaking the seal that is sent back to seal the engine from the pipe. only way 1 blower could work is an os 4 stroke engine with valves.

  • Gee, we want to see umm run. 

  • What a surprise! Just another shitvideo with an rc-car with supercharge just standing still, no driving! Very interesting video! Lol!!!

  • Nice, too bad the forced air goes right out with the exhaust on the intake/exhaust cycle dumbasses

  • superchargers wont work on nitro engines

  • @paultje162 hey asshole shut the fuck up people got to try if you don't like don't watch it

  • @paultje162 Yeah they will just look at a Top Fuel car they run the exact same fuel nitro rc cars do.

  • @paultje162 Yeah they will just look at a Top Fuel car they run the exact same fuel nitro rc cars do and Top Fuel cars are supercharged.

  • that other dragster takes solid rocket fuel! I wanna see that go!

  • Cant boost a 2 stroke dummy

  • At least ride it you knob...

  • EPIC exaust pipe! lol what is it 10 inches?

  • Unless you can dramatically increase the fuel intake on full throttle

    nitro superchargers sucks, you wil run on too lean

    and it will wear your engine extremely fast

  • woow that looks cool!

  • Very cool the dragster! I have a Revo with supercharger, but after I installed the compressor, it was much worse, you could give me a tip for improving performance?

  • their a waste of money does nothing

  • @euroboi101 thats true its proven

  • @euroboi101 Dissagree They look cool

  • @euroboi101 I spent hundreds in my rc's maintaned em and just fail everytime:(

  • @euroboi101 wats a waste

  • @euroboi101 these are but rc offroad monster trucks arent! you can jump bash and go pretty fast in one convienient package

  • @euroboi101 yeah kinda a waste of money but the thing is... they are enjoying playing around with these cars ...and everyone does different shit just like a hobby or w/e....so ENJOY LIFE....

  • @euroboi101 its not a waste, its a hobby

  • @euroboi101 if you would have one of these you wouldnt say that

  • @euroboi101 its a waste too you, the people that buy these things love the fuck out of them, its there money and this is how they enjoy, while other people buys video games or anything else

  • @euroboi101 bull

    

  • why wouldn't it work just look at micro boosts video

  • FI does not work the same on 2 stroke as on 4 stroke. A 4 stroke has the ability to keep all that pressure in during its compression stroke. Because a 2 stroke combines its strokes, the effect of forced induction is far less efficient than porting and raising compression. Because you are using a nearly "detonation free" fuel type, both setups make sense, however, volumetricly, the NA approach will make a consistently better performing engine.

  • lol these superchargers DO NOTHING but add weight.... its been proved so much times!

  • umm it is forced induction it forces more air in motor of course it does something

  • @jmb145

    DOES NOTHING!

    it actually disturbs the air flow, do you think the internals of that charger and flywheel power is so good it can suck air from that intake pipe? lol,

    i would rather spend abit less money on porting the head which actually does a job, fuck d.i.y no money spent!

  • @jmb145

    Forces more air in that just blows right over the piston and out the exhaust ports... No valves = no vessel to compress into... Once the piston's past the exhaust ports, it's also past the intake ports, therefore, making any forced induction, moot...

  • @DaViolentOne nerd.

  • @DaViolentOne Don't tell detroit diesel adn many other manufactures of blown 2 strokes...and port inducted blown engines have been done for a very long time.

  • @DaViolentOne so you are saying forced induction does not work on engines without valves?

  • @DaViolentOne where i can buy an engine like this???

  • @DaViolentOne well said, but u gotta admit they look good with the supercharger on it! :)

  • DAMN

    how bad is it trying to keep the front end on the ground

  • those superchargers dont do shit. end of story.

  • @SgtWaffles42

    LOL yeah but on a nitro engine, since there are no valves you can rule that out, and the critical part is not the carburetor either, which won't be harmed by the tiny particles. The problem is the glow plug, which is replaceable. The filter is mostly there to prevent larger particles from clogging the engine up, and or damaging the piston, connecting rod and crankshaft. Especially on dirt-type surfaces, not the case with a drag car.

  • So these particles can't damage the liner or burr up the edges of the ports then?

  • would my k59 savage motor be suitible to make a dragster

  • dude any engine will work.. it depends in what you do to the engine.. and with a savage i think thats the monster truck. it wont be that fast i think but yeah it depends on what you do

  • thanks heaps for that mate..

  • MRYOURJUDGE WAS HERE

  • simply bad ass

  • where did u get the drag tires at

  • you can get them at tower hobbies

  • Aww its a baby K&N filter. Did they claim it would get you another 90hp in your Mustang RC car?

  • lmao

  • AHA!! another level-headed, rational disbeliever in K&N's bullsh*t! good to see I'm not the only one who calls them on their bogus horsepower claims!

    And, if I am correct, this car's SUPERcharged, not TURBOcharged, right?

  • @gusu666 exactly.

  • @gusu666 I don't see a k&n air filter or a mustang ...???? wtf ?

  • nice. now put that engine into something that doesn't just go in a straight line

  • could you pleeeeaaassseee time your car with and without the supercharger and end this debate once and fore all !!!

  • Those super chargers dont work,it basically leans the engine.really speaking your engine will run faster and more efficient without it.what a waste of $150

  • and reduces engine life

  • running the compressed air through the intake of the carb also increases the fuel intake so it won't lean it,

  • no you have to compensate for it... have too much pressure and your fuel will blow back thru the carb...

  • You do realize that those RB innovations superchargers DO NOT WORK.

  • jesus crist!

  • Oh shit :DD looks very nice, good job !!

  • those are nice cars

  • Ive heard super chargers really wont do alot for your car.

  • They don't do anything, just a nice expensive way to reduce engine life.

  • theyll do a ton to you car..theyll blow up the engine and waste a shitload of money lol.....superchargers cant go on 2 stroke engines anyway...rb just found a way to rip peole off

  • supercharges work fine on 2 stroke engines, only problem is won't increase revs only tourqe so you need to build up your engine to handle it, same thing with 4 strokes

  • dude the revs and torq are total different things but yes you can run a super charger on a 2 stroke. a super charger will never effect the revs of the car

  • Mate I'm well aware torque and revs are different, but it's good to see someone else that knows what supercharges do and how they work.

  • @ammyg123

    You're wrong, yes a Supercharger will affect the angular velocity of an engine because it has a parasitic effect on it. Also, since it produces boost, and increases the horsepower, the engine now has more torque at high speeds and can effectively achieve a higher maximum RPM value.

  • @corotor12345

    It is also leaning the mix and again, raising the RPM at any level.

  • dude im not stupid about this stuff but no you will not achieve higher value.. you'll hit the limit quicker but not any higher.. youll need to put like an ecu chip on it but that will never work out because even if you hook it up to the engine some how. either the pistons gonna blow or your gonna crack the block just like that

  • How far into this do I have to go to prove you're talking cobblers. A supercharger robs a significant amount of power from an engine especially at high rpms. The rpm limit of an engine is usually decided by the mechanical limitations of the components. Yes gas velocities will come in to play but not before the con rod is in more than one peice.

  • @azonicone

    Of course it will damage the the liner... is it that important to not miss something? and well, yes, it does draw significant power, but that entirely depends on the supercharger. If it's an RB Innovations, it will be counter productive, performance wise. But with fluid dynamics and stress simulators I've been designing a supercharger I'd like to build which will have little parasitic effect. I'm not talking cobblers...

  • @corotor12345 Surely though a supercharger that has very little parasitic effect on an engine will also produce very little boost pressure. That is evident simply through the laws of energy conservation and mechanical efficiency, unless you've discovered a new branch of physics in which case myself, along with most motor industry professionals would pay good money to see such a thing...............

    That is all...........

  • @azonicone

    Not at all. I claim no new inventions here... I'm speaking of, say, what, 75% compression efficiency? which is a lot for RC superchargers. And just below the high-end superchargers peaking out at 78%, so yeah relax, I'm not a troll, and I'm not the stereotype you're thinking I am.

  • @corotor12345 Hmm I'm interested. Have you studied the effect of a supercharger on the BMEP of a 2 stroke abc engine?

  • @azonicone

    BMEP... that's a tough one dude. I'm 17 years old, and I live in a third world country. I have trouble already, only with getting the god damned engine, and now you ask me to study the BMEP? I can calculate it for you if you want, but I need a powerband chart, and I lack the competent dyno.

    BMEP, BSFC, Thermal efficiency and that sort of mumbo jumbo is almost impossible for me to calculate accurately, under any circumstances. I'm tryna be practical here...

  • So you're making this advanced, super efficient supercharger on nothing more than guesswork?

  • @azonicone

    Well look at you Grand Prix engine guru. No it's not only guess work... It's fluid dynamics, stress simulation, smart decision taking, innovative component placement, stuff that hasn't been fitted into forced induction like kinetic energy recovery, thermo-electric parts, resonating devices and the like. For example, I'm working on an amplifier to boost the plugging wave, in order to actually have some boost.

    Think you can do better? Go ahead... at least I aim reasonably

  • @corotor12345 So you're going to do all this without first establishing a baseline? Not sure myself what the excess charge (if there is any) will do to the reflected pressure wave, but then again you're probably going to re-invent the tuned pipe.

    Im certainly no engine guru but I do know that using a higher nitro percentage fuel and a decent tuned exhaust will add more power for a lot less expense and hassle.

    Im an engineer, If a job isn't worth doing right, it's not worth doing at all.

  • @azonicone

    This is an experiment. It's only to test some concepts. You can tell me whatever you want but I'll still build it, with tools that are fit for the job, but inside the realm of my budget.

    As of now I am unable to do almost anything because I broke a bone on my left wrist, on my recently purchased YFZ450... That's my priority right now, enhancing the race ATV. So if yo don't mind, I'll go this way and you can go that way, thank you.

  • I think a stand-alone motor 4 the charger say 1/3 the size would do great. The gain might be greater than the sum of 2 motors. What do u think?

  • @superkindonmymind

    Well, energy comes from the air/fuel mixture. But the problem is always efficiency. You say two motors, uhm, motor means electric... LOL just so you know. Anyways, two nitro engines are not efficient together, and it's just easier to use a larger engine. Now, Electrically assisted superchargers are something to consider. By assisted I mean not fully powered by an electric motor, but with a double coil system so that it can be boosted electrically maybe? who knows.

  • If a car with a 4 stroke engine had an onboard stand alone charger u could run the charger engine at low speeds, the main engine at midspeed and charged together under acceleration

  • @superkindonmymind

    How old are you and how much do you know about internal combustion engines? Friendly question =)

  • 32 and im a auto tech, all this is cool this is cool but the real benefit it recovering kinetic energy from braking without a flywheel. Thats the future.

  • @superkindonmymind

    I'd have to disagree. The future is not only that, there's FSI and other technologies like that that are very important also. And, anyways, why do you want a KERS without a flywheel? It's the most efficient of them all, and the simplest to manufacture massively. Anyways, we were discussing Superchargers on two stroke nitro-run RC engines. I believe it's possible with extensive modifications to the engine, and I want to add a few things to the setup... things that are unique.

  • no point in electrically assisting a supercharger, would be in a turbo though.

  • @haydondres

    course there is. The turbo charger is the ideal forced induction setup, and in RC nitro two strokes we are limited to superchargers. The whole point is to try and make a supercharger as close to a turbocharger as possible... and that includes keeping it spooled, as to not experience the parasitic effect under engine acceleration. This means I have to drive it off a one way bearing, and assist it electrically with a capacitor and a dual coil motor.

  • can these engines be put in a normal nitro car?

  • nice

  • Even though i've never tried them i can tell you what is actually happening when you see a gain from forced induction on your average two-stroke. First underst
