LS2 S/C - 505bhp and 520lb-ft - From GM
FYI:
It's in this car:

This is a GM design and product. Not aftermarket and as far as I know, not for sale...at least not yet. But it seems too well thought out for just a show car.
Interesting. Wonder if there's any plans for production. Or maybe a kit from GM Performance in the future.

Supercharged LS2 engine
Source: GM with Eaton
LS2 vs. LS7: The LS2 was developed as powerful yet refined engine. This makes it a perfect base architecture for this vehicle. The LS7 is a performance engine with an aggressive torque curve, making it less suited for the refined Cadillac character. To enhance the package, and truly place this vehicle in the performance arena, the supercharged LS2 maintains its base refinement with aggressive power.
The engine being used in the STS SAE 100 consists of a supercharged LS2 yielding 505 hp @ 5600 rpm and 520 lb.-ft. of torque @ 3600 rpm at 7 lb. of boost. General Motors has developed the integration of the Eaton M122 inner cooled supercharger to the LS2.
Engine type: OHV V-8; aluminum block and heads; 6-bolt main bearings, forged steel crank; powder metal connection rods; displacement 364 cubic inches / 6.0 liter; bore 4.00 in / 101.6 mm; stroke 3.62 in / 92 mm; compression ratio 9:1. Fuel delivery is provided by returnless, sequential port fuel injection.
Next-generation electronic throttle control (ETC)

Throttle actuator control (TAC) module hardware and software moved to engine control module (ECM) internally. In doing this, the stand-alone TAC is eliminated.
