Those things are completely useless....all they do is cause a tuning nightmare becauase u usually end up having to lean out the engine almost to the point that it can overheat in order for it to propely run, and that, as we all know or should know anyway, is a good way to lead a perfectly good engine to a very early death....

Status: offline 		well, the way i understand superchargers, is that they require a low compression ratio, wich these motors definately dont have.. i can see a turbo working on these motors.. think about it like this.. once your motor is running, you dont need the glowplug to fire once the motor is running right? since these operate like diesel engines, the compression ignites the combustion process, and voila.. how many supercharged diesels have you seen? i havent seen any..

just use a higher nitro rateing

Status: offline 		Turbo wont work real good, need a closing valve even more than a supercharger, these RC superchargers do work, by advancing the scavenging abilities, any way you look at it they give a small gain of power, thats not to say there worth the money you spend on them for the % of gain, frankly there not, but in princible they do work, as fiddly as they are to tune if you know what your doing you can get them to run pretty sweet, and l can say this, they sound bloody awsome, mines an RB one lve only had it a few weeks, doing some pretty full on testing with it, wwanting a new fan for it to go from 30% boost to 50% boost, LOL, will be a few months before l post any results and decide whether there really anygood overall, but they DO work.
Mines hooked up to a 4.6 kyosho engine.

This topic has been raped to death !

Status: offline 		Sorry compadre!

Im pretty new to the scene

Heck, I just made a thread asking about springs.. When I could have searched nstead :P

As for the turbo, I forgot about that popup valve

Back to the supercharger, do you have to run your carb alot richer?

What kind of motor do you have?

Status: offline 		Oh god another one of these threads.lol Ill save you some time they work but not well enough for the stress on engines. Youll have a few guys going back and forth about it and nothing usually gets solved. I hope that this dosnt come off as short or anyhting I have seen threads on this subject get really heated.

Status: offline 		lm running it on a kyosho 4.6 in an inferno, yes its a good bit richer but lm still messing with it, l find it touchy to start alot , especially in cold weather, unless its 80% ish humidity, then it starts ok, lm in queensland australia, so its humid, but l would be lieing if l said it was for the novice or if l said there not fiddly, cause they are, and there not worth the money for the power gains, but they are fun, sound sick, and do work to a limited degree.
When lm happy lve had enough experience useing it, l'll start a thread with pic's and a video, these things take time though .


Well said mspeed below.

just use a higher nitro rateing

Any forced induction power adder wether it be a supercharger or turbo will increase the compression in the combustion chamber and then you just add more fuel to get more power. If your compression becomes too high you will preignite the air fuel ratio and get premature detnation. So most engine maufactures lower the compression ratio to give room for a higher boost level being either a turbo or supercharger. On a gasoiline engine, if you raise your octane level and have a well thought out designed combustion chamber, and retard the timing enough you can run a higher compression level without premature detnation.

On diesels, you do not have a ignition system, they rely on glow plugs to get a start and then the compression gets high enough to self ignite the airfuel ratio, so a turbo or supercharger would fit right in with some tweeking. The biggest difference between a turbo and supercharger is how it achieves its boost. The turbo is more efficent because it is run off the exhaust to turn a turbine that inturn creates boost. The supercharger runs off the motor pulley and belt or chain system on some. So the supercharger takes away some power to achieve more power.

Sorry for getting off topic, but I would think compression is not a valid reason why manufactures dont use superchargers on diesels. It probably has more to do with efficency.

For our nitro motors, I would think its possible to see gains if you get a tuned pipe that works well. I have used the buku and it acts like a backpressure valving control system when adjusted right on. Its not a real open and close valving but if your running on the pipe through the whole rpm band it helps with compression and scavanging out exhause so I would think you might see some small gains with a good adjustable pipe like the buku and a supercharger at low boost.

Without a valving system you just lose some of your boost right out the exhaust port in our two stroke motors. The problem with a turbo on our two strokes, is they need a exhaust set up to properly spin a turbine. Our nitro motors rely on a tuned pipe to control the motor tuning and power etc. therefore, its hard to incorperate this all in a effective design as one.
