No benift at all
There is currently no commercially available turbocharger small enough to provide a flexible match to a 100CC engine. If this is a 2-stroke engine you are slightly more likely to find a turbocharger that can give you a a small benefit at the upper rpm range, nevertheless, it will not be a flexible power-adder. Instead, try to contact a manufacturer of nitrous-oxide kits and find out if they can provide a custom nozzled kit suitable for your power needs.
The supercharger is an engine power adder for vehicles. It's purpose is to make an engine more powerful instead of using a larger heavier engine. The Grand Prix GTP uses a supercharger on its V6 engine to make power levels comparable to some naturally aspirated V8 engines.
battery not holding a charge, altenator not putting enough power.

If it was, the engine wouldn't work - you would be putting more energy in than you got out.
you will overload your generator
The powerband is a term for when the engine is putting out usable power (its actually the term for a graph showing this) its not an engine part! I would think you need to set the carburetion or timing problems
This will benefit you in many ways. They have greater click-throughs, the power of branding, greater trust and organic is free. The disadvantages are that they are not automatic and require an investment in time.
A power adder such as nitrous oxide injection, a supercharger, or a turbocharger would be the easiest way to get to 500. If you want to do it without a power adder, you'll need more than 10:1 compression, good heads, and a roller cam.
The new solenoid is faulty or it was not the problem in the first place. See is it getting a proper power supply.
your amp will ground in your sound system, or through your power adder which rock.
Engine power.
