Has anyone tried using supercharging or turbocharging on the typically 'small' engines we use in models to increase power?
I am just curious. The usual way to get more power is to "use a bigger engine" but therein lies the problem, it is bigger in dimensions too and may not fit in the scale sized body, and thought struck me about increasing the power of an existing engine as many car manufacturers seem to be doing today.
Food for thought.

Where are you going to find a small enough turbo charger or supercharger for these small engines. also when you start boosting the inlet you need lower compresion ratio's, possibly piston cooling oil jets, different valve and seat materials & oil cooler. Oh yes and improved cooling.

Perhaps increase the compression ratio, polish the ports, if a 4 stroke, enlarge the valves. Reduce friction points, some bearings might be replaced with ball races over plain ones. Carefull balancing, and lightening of parts such as pistons, and lighter, but stronger con-rods. Small superchargers/ turbochargers have been made for some very small motors, but they increase the size of the motor quite a bit, might be just as good, and easier to build a larger motor, a motor with a larger bore (thinking of single cylinder)is no bigger to any great extent,ie., 1\2" bore to 5\8" bore, or what ever you have. isc

I forgot to add a pressure lubricating oil system which has enough excess flow to cope with the oil flow that a turbocharger requires to lubricate and cool it's bearings.
