How are piston engine aircraft pressurized

I have scoured the net, and cannot find any info. How are piston engine aircraft pressurized? I'm talking aircraft such as the 210, Baron, Aerostar, etc. I know jets use packs via bleed air, but seeing as how pistons have no readily available source of bleed air I have been curious.

Usually bleed air off the turbocharger. Routed through a venturi and/or heat exchanger of some sort for cooling and noise reduction.

At least that's what the P210R Information Manual from the Richman Memorial Aviation Library (IE too lazy to throw anything away closet) has to say about it.

Usually cabin air volume requirements of a piston anything with 4-8 seats are quite modest. You're not trying to pump up a Connie or anything like that.

And the max cabin pressure differential is only 3.35 in that plane. Not a huge demand.

Or, they could do it Boeing 787 style, and run an electric compressor :)

Elves blowing really hard. Same place wind comes from... read up on your Wx theory, bro.

You simply take a good airplane, like a Baron, and you add some extra tough seals on the door that are ill fitting at best. Blow in some Turbo air through a ACM like device, and make everyone as uncomfortable as possible as the plane seals itself intermittently giving the cabin pressurization a yo-yo like feeling that would be funny if it didn't hurt your ears so much.

Yea, but P Barons are so cool that those with you won't mind.

You'll have to wear shades around the clock, because when you're P Baron cool, the sun shines on you 24 hours a day.
