I just can image how insane that thing would look fully polished. 
It's awesome that they chose the TVS series. They are really efficient and have a big power range. For instance, the TVS900 has a max flow of 1000m^3/hr or about 406HP. It's a bit on the small side but it's still be perfect because that's almost exactly what our cars would make on 14.7psi of boost.
I doubt it, but if they went with the TVS1320, then we'd see a max flow of 1400m^3/hr which equals a max of 568HP. That'd be nuckin' futz. We'd have to have forged everything and a 8.5:1 CR because that much flow would mean we'd be at 29psi of boost.

depending on the pulley of course! a 1320 at 11 psi should be good for about 330-350whp if using a lotus elise 1.8L at 11.1 compression is a decent example. i could see our car putting down around the same with a much lower Redline (1000 less) and probably 10 psi (1320's peak efficiency). 29 psi and you are making way too much heat. and imo this engine will never need to be dropped below 10.5:1 or even 11:1 compression for boost. no sense in losing throttle response.
