Those that are worried about the 12.5:1 CR shouldn't be. That what the stock Ford Contour SVT 2.5L Duratec was running. They boosted them to 350HP on stock internals and were only 220HP stock. Having it fully intercooled will make it very safe.
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.
