Superchargers for small engines
Assuming there isn't an off the shelf supercharger solution for small engines (100cc-500cc)
Can anyone think of a small mechanical compressor which may may work?

Id look for a small turbo for a 1L engine or even a normal one. Then look for a bleed valve or adjustable actuator to adjust boost pressure.
ETA: Same with superchargers, though they are rarely used on engines that small. The eaton M45 is the one from the mini which you may be able to
change the pulley to a larger one to slow it down a bit. Check the compressor map before doing that though.

Can you give a bit more information about the engine?
There are things like Smarts about they had 600cc turbo which is pretty small. But obviously still too big if this is going onto a lawnmower!

Can't give really elaborate much as it was a general question bout pressure charging small bike engines. I have nothing specific in mind

would a 100cc engine have enough power to even run a super charger?

A serious consideration, there's no way that small an engine could turn an eaton m42

Its a bit off the wall ... but some kerosene burners use a small air pump to atomise the fuel.

Good call. Initially, thats all superchargers were designed for, Air pumps on furnaces. - Apparently.

If you really must, AMR300 and AMR500 are 300cc and 500cc respectively. Off small Jap Kei cars (Subaru?). They come up from time to time on fleabay
from the jap importers in Oz, so I guess they are available elsewhere.

The AMR300 and 500 are Aisin superchargers - sometimes helps to search by Aisin rather than by the particular name. I noticed a lot of places just
list it as a Aisin supercharger for YYYYY vehicle.
They're not what I'd call tiny though.. certainly quite chunky for a 100cc motor!

Damn beaten to both my answers! I was also going to reference the Kei class supercharger and the Peugeot scooter as I want to buy one for hooning to
work on.
Have a search on autospeed.com for old articles about the kei class imports

I'm struggling to see the point of the Peugeot supercharged scooter. Complicated, bulky, heavier and very likely thirstier than a 250cc engine,
and since you are restricted on power as a learner on a 125cc bike, it doesn't get around this.

My understanding is that a supercharger soaks 10% of the power just spinning it up.
If you must go down the forced induction route surely turbo has to be the way to go given it's power is "free"?

Turbo power is not free, that's a bit of a misconception, it is just lower loss than a supercharger. But it provides a different set of
problems/benefits. General thought process is that turbos are good for all out power (drag), and SC are good for drivability, but that's
dependant on what turbo or SC you choose etc.
Check out some of the FSAE / Formula Student turbocharged cars, they generally use super small turbo/superchargers as they're limited to 600cc
engines max (many run smaller) and pretty hefty throttle restrictors.

yep, was just thinking of r/c engines being supercharged. it does happen!
