it's like a turbo but belt driven. That's about it.

I don't know much about it for the M20, but it's the go-to forced induction solution for the S2000 (my daily driver). I've looked into it a number of times, and plan to go for one in the future. Like Yoshi said, using a centrifugal charger is going to be pretty much the same as turbo charging, aside from mounting the charger and running the belt for it.

As far as I know, no aftermarket companies have developed a kit. It would take some pretty extensive and precise fabrication to implement one. I don't even know where you'd fit one in the engine bay.

Given the number of people who have constructed all sorts of DIY turbo set ups for the M20, I'm not sure a centrifugal charger is really worth the effort. There are other solutions that give the same results, and the R&D has already been performed by other members of the community.

That said, what are you trying to accomplish?

There are a couple companies out there that offer kits, but at $3k+ for a low boost system it doesn't make much sense. It's similar to a Turbo, but power delivery is very different. Like any belt driven pump it's linear, unlike a Turbo. A few people have built their own setups with varying success, but again, the cost is WAY higher than a Turbo, or even roots charger build. The benefits are in weight/space savings, and a slightly more efficient compressor. Again, if you want to SC a roots type, like an Eaton, will be much cheaper. If you have the coin and want something different go for it, and take lots of pics. ;)

I always used to think about it like:

Roots - Low End
Centrifugal - Mid-range
Turbo - Top End

But I've come to realize it's never that simple. Given the cost difference, a turbo on the smaller side will cover much of the same area as where you would feel a centrifugal charger. A centrifugal supercharger seems to give a very linear powerband, whereas a turbo will have no low end, or a roots will flatten out up top.

Haha! Thank you guys for the input. I knew all I'd need to do is ask one quick question to get the answers I needed.

I was hoping it would be simple... fabricate a place to mount it, run a belt... injectors.. ms2... :U Good to know!
