Default superchargers how they effect an engine??

hi ive been looking at these superchargers and am just wondering how they effect efficiency of the engine.
does anyone experienced know how they effect an engine in regards to fuel/air mixture do they cause to less of a fuel to air mixture resulting in low lubrication which causes engine wear?

and how does the fuel pressure valve effect efficiency/performance does more fuel pressure result in better efficiency and/or how does this work?

any opinions/experiences in regards to these superchargers?
i basically want to know the principles and dynamics behind how they effect an engine.. thanks.

Those are very effective in removing money from your wallet. But they sure do look cool.

Basically all a supercharger does is to charge more air, and with that more fuel, into the engine than it would normally take in giving more power since it's burning more air/fuel mix.

Now think how your model two stroke engine works. The air/fuel is pulled into the crankcase and then the pressure from the piston coming down forces the mix into the intake ports and at the same time opens up the exhaust port. The incoming mix forces the burnt gases out the exhaust port. That's the timing of a model 2 stroke. A supercharger would end up pushing out the unburned mix with the burned gases and you would have about the same amount of mix in the chamber as you would without the supercharger.

they don't actually work on a rc vehicle. There are way too many variables that they forget about when it comes to 2 strokes.
