RE: proper nitro engine supercharger?
Quantum, theoretical, applied and mechanical physics? are you kidding? i think the kid should put the super charger on just so he can say it's "SUPERCHARGED". he can spend time with his dad and when the two of them run against a guy with a badly tuned motor they can say they beat him cause they were SUPERCHARGED!!
of course that's my opinion and i'm sure someone else is more of an expert on having fun and being a parent so they can come in and blast my theory out of the water.

Well I do own a dyno for these engines...maybe one day I will get my hands on a supercharger and give it a whirl.... I am of course doubtful it will produce any extra power, but I am more then willing to give it my best to make it work....

RE: proper nitro engine supercharger?
Running one on the Xdyno would really tell the truth.
I can give you a cheap way to really test it.
If you have a air compressor, you can use compressed air directly into the venturi, you could go to the desired amount of pressure, you could even throw 100 psi at it...
I tried the RB supercharger for someone 2 years ago, and i spent sometimes messing with the tuning, and the engine felt stock to me.
I suggested him to run a better tuned pipe, i suggested him a model, he removed the supercharger, did a new test and picked up 8mph...

they are hard to tune.

Huh....no
It was really easy to tune, i just test drove it for a while and tested some tunes to really see if i could get more out of it...
It was as easy as stock to tune, and it was not overheating more than stock, runtime was also similar.
It just had no power...

Ideally we need someone from the RC world who has access to an x-dyno to run the tests and put this to bed once and for all.

as i'm sure you know not every app is the same. when you put the pressure tap on to add more fuel pressure and a one way valve with a drilled out carb. restrictor plates are needed. the tuning can get a little hairy.

1) "Pressure tap/one way valve"- There is an extra pipe running from the charger impeller to the tank that has a tap and one way valve?
2) "Drilled out carb"- You bored through the venturi of the carb?
3) "Restrictor plates"- ?

Ok you lost me there and I have a few questions:-
1) ''Pressure tap/one way valve''- There is an extra pipe running from the charger impeller to the tank that has a tap and one way valve?
2) ''Drilled out carb''- You bored through the venturi of the carb?
3) ''Restrictor plates''- ?
How did you establish that there was any gain?

on the rb supercharger there is a threaded hole for a pressure tap.
coming from there and the exhaust you put Y split going to one tube into the tank.
on the exhaust portion of the pressure tube you put a one way valve to keep pressure from escaping through the exhaust.
it puts a lot more pressure in the tank and holds it during low speeds and idle.
yes i drilled out the carb to pull more air( like puting a larger carb for more power on your daily driver )
that .12 had a ton of juice without the supercharger to the point if you stabbed the throttle too much on a launch it would break traction and throw it self into a tight little doughnut.
after i installed the supercharger, it became a little touchier with the throttle to the point where it was almost impossible to make a 1/3 throttle launch.
i've been drivin' for a long time and know the feel of my cars. it's not hard to tell when it has more torque.

Other than the carb mod, what specific mods did you do on your engine?
What is your timing profile of your ports?

RE: proper nitro engine supercharger?
you'll have to give me a couple days to get pics . at the time i did this i did not have a digital camera and the engine has since been sent to va. to my buddy as i have switched to a big block in my NTC3, but here is a pic of the NTC3 now.please keep in mind i have not dialed it in fully as i am a busy guy with many other things going on and just got the new piston/sleeve broke in.

RE: proper nitro engine supercharger?
ORIGINAL: SAVAGEJIM
Yeah, I am a scientist, in the applied aspects of it. I have studied it as it pertained to engineering (thus the applied aspect) and have worked in the highway departments. I am now back in Texas again and in the highway department for Texas again.
I totally understand that not understanding the science and the physics concepts can lead to alot of misunderstandings. Trust me, I walked into college with tons of incorrect preconceived ideas of everything only to be kicked in the pants hard by the physics professors.
And these guys are some serious scientists, even more so than what I will every be. I know that at least three of my physics professors do not just do applied scientific research, they do pure (theoretical) research, and one of them is still involved in the C.E.R.N hadron collider in Europe.
So pure (theoretical) is their research that they are looking for primordial elementary particles that are hypothesized to only have existed during the dawn of space & time (i.e. during the theorized big bang).
I have some limited understanding of quantum mechanics, and also even quantum theories, such as the grand unification theory, but my knowledge of these pale in comparison the the vast knowledge my professors have of all this.
If you want to know more about large hadron colliders and also for the search for elementary particles (the Higgs Boson for example), do hit the net. There are some very nice explanation on what possible significance this kind of pure research can have to improving applied science (for example, the realization of fusion technology).
Aside from quantum mechanics, if you want to learn more about the more classical physics as it applies to our discussion of supercharging, check out Charls and Bolye's gas laws. They deal with pressure, volume, and temperature (so far, only Supertib has mentioned temperature as a factor to supercharging). And intricately tied into these physics concepts are density calculations as well as the work-volume theorem and how pressure, temp, & volume play into that.
EDIT: Corrected the use of the word ''Hadron'' in my explanation above. The correct term is ''elementary particle.'' Boy, would my physics professors given me another swift kick in the pants again if they read that mistake!

Oh and it's all theory, there's the theory that any solid object comprised of atoms can spontaneously decompose and recompose, in other words, travel through another body. Has anyone walked through a wall yet? No. Case and point, it has absolutely nothing to do with the real world as we know it.
So you're telling me that^ has something to do with 400mph winds(at best, with a supercharger), then damn, we have a problem, because we'd have miniature black holes popping up in supercharged nitro engines throughout the globe.

The only reason why I brought this sort of thing up was because my knowledge was being brought into question and if you read Bigdog's sig, one of his lines in his sifg sas to trust no one. He is therefore a skeptic and requires a bit more demonstration that one is simply not pulling information out of the air.
I brought up quantum mechanics to try to demonstrate to him that my knowledge comes from formal education and that I am not trying to put misinformation into this thread.
Also, if you read halfway down through my post I mentioned another concept physics concept that is actually physics facts (what are called "laws" because they are no longer just theoretical, like the idea of the Higg's boson).
The physics laws I mentioned are are the gas laws which are 100% applicable to our discussion of supercharging.
Can supercharging cause mini black holes? According to much of theoretical quantum mechanics, especially because of its reliance on probability, nothing is impossible. And under such theory, a more macro-physics phenomenon (fluid dynamics for example) can cause mini-black holes is possible, but it is very very very very improbable. (Unless you have some sort of fantastic probability drive like out of the book Hitchhiker's Guide to the Universe.)
In summary: I only mentioned theoretical physics to demonstrate to Bigdog where my knowledge comes from.
I then ended my post with applicable physics laws (not theoretical physics) that ties the post back to our discussion about supercharging.

oh wow. it seems it is all theoretical and every one has opinions. i mean savagejim is a scientist for cryin' out loud. i'd like to see the proof, but all i hear is big words of someone who is tryin' to wow the readers of this thread and make them believe he's a scientist, but where is the degree? baffle'em with BS. you go savagejim. i live on earth, i don't know where he lives.
superchargers, buy them or don't the choice is for the people to make. i mean how many have really tried one? i don't take anyones word for anything, i have to see for myself, so i tried one. i think this thread has gotten rediculously off topic with scientific theory. much like the ramming of ones trying to make people believe they are a scientist, and i bet he can fly too.
i will never post in this thread again. thanks for making RCU and this thread such a headache.

RE: proper nitro engine supercharger?
One of my Team Drivers tried one out for a friend of his as he knew better then to waste his own $ on one 
He goes by Over-Revo on the forums. The buggy that he tried it out on was faster with the SC off.... You can ask him all about it. But it was a waste of $ and time from the feedback i got.

I believe this is a discussion forum so, should someone make a statement about something that I either think is incorrect or I do not understand, then I will ask them to explain.. During and after the discussion I can form an opinion of their knowledge (on the subject matter) based on their replys,their credentials mean nothing to me.

So as my understanding of the loop scavenging theory and history is telling me supercharging will not work, therefore I need some evidence/facts from the person saying that they do work.
No evidence or facts have been supplied, which leaves us only the theory to discuss...no?

water turns to steam, and steam is indeed inflamable. however, when i attended auto tech, one of the first things my instructer showed us was a way to raise the combustion temp by spraying water into the carb, and i wouldn't have beleived it if i hadn't seen it for myself. it does indeed raise the temp and to watch the carbon coming out the exhaust made a believer out of me.

RE: proper nitro engine supercharger?
Chiming in a little late on this thread, but supercharging a two stroke engine is almost pointless. You may be able to cram a few extra psi's into the crank case but that would be it. The crankcase volume is relative to the displacement... increase crank case volume (increasing psi) would do nothing but force too much fuel mixture into the cylinder... and right out the exhaust port. You would also be messing with your expansion pipes timing, thus removing any power gain you hoped to achieve. The only two strokes that have successfully been turbocharged/supercharged are two strokes with exhaust valves.
