It isn`t real
Just do a search on this RB supercharger, it has been tried and discussed many places on the web and it doesn`t work. It can`t work as long as the exhaustport is the last port to close in a twostroke (any overpressure will escape out the exhaust). This unit is made especially for car engines and provides nothing more than just the looks and adds weight to the vehicle and at a big price

If you like the centrifugal blower, you need a Nitrous system to go along with it?

http://www3.towerhobbies.com/cgi-bin...&P=SM&I=LXPXU3

They have several models of blowers

http://www3.towerhobbies.com/cgi-bin/wti0002p?&M=RBV

Let me see now . . . . $150 + $180 = $330 Not bad for superior bragging rites?

And if that isn't enough, you wouldn't be a real man without a K&N air filter to go on it for another $30

All this fun and jest . . . This might just be the ticket for a OS FS52 or Saito 62? It will not work on the OS & Magnum engines with the positive crankcase ventilation.

You may, or may not have noticed that tower has been busy dumping these in their "closeouts", and "overstock", for the past few months.

Wonder why

....they might work (give a boost) to a four stroke engine.

It might. I would like to see what the compressor wheel in these things really looks like. Of course, if it really did make boost on a fourstroke, a equal or slightly greater amount of fuel pressure would be needed at the carb spraybar to overcome the pressure in the intake tract. This is where things get complicated.
This really makes you realise the beauty of the YS fuel system and how well it works.

I was thinking the same thing. But, I don't run 4-strokes and I am not spending +/- $200 on a super charger and another $200 on a 4-stroke just to find out. I'll let someone else do the research.

Agreed on the 2-stroke application-- it'll never work. Waste of $$$$$.

Best thing you can do for a 2-stroke is put a tuned pipe on it. But, with smaller engines, it tends to make them peaky. They run great when "on the pipe" and they run doggy when they are not on the pipe. Makes for a very narrow powerband. Hard to control. Great if you want to race or go fast. Flick the throttle wide open and watch it go like nuts. Horrible if you want to 3D where the throttle is being juggled up and down constantly.

Totally different on a larger gasoline engine. Most gas engines will respond VERY well to a tuned pipe. They give great performance over a very wide powerband without any of the "peakiness" usually associated with small glow engines.

Of course, these are generalizations. It's possible to put a tuned pipe on a small glow engine and get smooth power over a large range. But, you will not get that MAX HP that most people associate with tuned pipes. You CAN get more power than a stock muffler if you tune it right. Tune it for torque by cutting the header to the right length. That gives a mild improvement in HP and offers smooth transition over a very broad powerband. You can't tune for maximum HP and expect it to transition worth a darn. You can make a small 2-stroke go like nuts with a tuned pipe, if you cut the header short for max HP. But it won't idle or transition well enough to satisfy the needs of most sport flyers.

The question are: how much are airmass and pressure are pumped with centrifugal compressor to fill the cylinder..

....yep. The question is, does it pump any air at all ?

It is easy to test the pressure are enough, mount the silicone hose between compressor and intake manifold. Run the engine at max rpm, you will feel there are pressure who are blowing up the silicone hose or not enough pressure.

I did each time i tested the turbocharger in car are ok or not when i pressed the hose before i gave the engine full trottle, the hose will be expanded by pressure means the turbocharger are ok.

Superchargers on model glow engines may not work but they sure as heck do on two stroke snowmobiles. I watched a race a couple of years ago where the guys without superchargers got their collective butts kicked by the ones that had em. It was a very significant difference. I talked to one of the mechanics and he said it was very critical on how the pipe was tuned. I guess the right pipe can stuff it all back in the cylinder right before the exhaust closes. Just a guess.

The centrifugal compressor does better at high rpm than low. A positive displacement Roots-Connersville type blower would give more low rpm power but the Centrifugal will do great at full throttle.

That buggy was really slow, my Hyper 7 with STS .30, 0702 big bore pipe and the optional two speed is MUCH/ALOT faster and quicker.
I goes to show that this blower is just bull, but it sure looks cool. For the cost of it he could have gotten a better engine and pipe

Maybe if I install it on a STS .30 with a 0702 big bore pipe and a two speed it will be faster than your Hyper 7?

That teeny-weeny rubber band of a drive belt is a dead give away that the blower is just eye candy.

Bingo! Give that man a cigar!

Anybody can install a larger engine, a better tuned pipe, more tranny speeds, and more nitro. Of course the vehicle will go faster with those.

As for 'eye candy', isn't that what custom paint jobs are? Custom wheels? Polished and anodized aluminum parts? Or in the case of airplanes the covering job, the polished spinner, the working lights. None of it makes the vehicle faster. It's all for the pleasure of modeling.

hey guys, had a bit of time to tinker, so just for once, how does an exhaust driven turbocharger sound to play with?

I guess it depends if it actually works or not. In theory it should work, but there is a lot of skepticism about forced induction on an RC engine.

I really hoping it works, i have always wanted to see something like this work. think im going to run an auxiliary fuel pressure port off the turbo manifold plate, more pressure more fuel more fuel more lube, more lube cooler engine temps right?, with most of the exhaust muffler mount space covered by the turbo manifold plate with the only small turbo hotside inlet for the exhaust to escape through, so im hoping that it allows for more of the fuel to get trapped in the cylinder. what do yall think
