Quite interesting. I suggested the Rotrex in a couple threads before. I had a C38-81 I was planning on throwing into my Acura but sold it about a month ago, as I'm parting and selling the Acura. The Rotrex method is a lot simpler than using an Eaton-type unit that requires a *lot* of modification. You need to have a mount made for the s/c, run the piping, get a pulley made to power it, and you're pretty much done (outside of fuel and tuning issues that need to be addressed). HKS also makes version similar to the Rotrex.
I thought about using the Rotrex on the VX, but with mpg kinda borderline as is, I didn't want to lower the mpg even more, as at least one of the 2 vehicles I have needs to get decent gas mileage.
Edit: Looking at the video, he went with a Synapse Engineering blow-off valve. *NICE!*
Oh, and you can pick the s/c up here for $2095.
