more time and money than sense .. WTF would you do with that aside from bolting it to a go cart or similar
I like the "idea" of a supercharger, but the practicality needs to be justified (does it actually produce any more power?).
A dyno test before and after would be a good start.
One of the historical problems of adding a supercharger (mechanical mostly, but also applies to exhaust turbines) is where to put the carb - before or after the pump?
- before the pump is easiest, but the fuel droplets tend to come out of air-mix and wet the walls causing the air-fuel to vary according to revs
- wetting the rotors with a solvent like petrol can cause rotor wear.
Mounting the carb after the blower is better for many reasons, but most carbs are vented to atmosphere (for reference pressure) and don't cope with a positive pressure on the inlet. SU's are the common pick (the ref. pressure is sampled at the inlet)
Then of course there is lube and cooling - on an engine with no oil pump (splash lube), you can't add an oil cooler and you can't improve the oil flow.
Materials - will it hold together?
And a small problem of compression - force more air in and the compression pressure goes up - so you need high octane fuel unless you lower the compression (ie. drop the compression ratio for the same final pressure) or it will pink (pre-ignition) badly
