Straight from Japan on the Wangan, this "twin charged" Nissan Skyline GT-R by Power Enterprise is a representative of the highest automotive technology in the world using two forced induction systems working together as one in mechanical perfection. What is Wangan? See here. Typically, a car is either turbocharged or supercharged. It is very rare to see these two systems working together. The turbos feed the procharger style supercharger boosted air that is made from energy used out of the exhaust system. That extra force of air keeps the lag minimal as it forces air into the supercharger spline. This helps push the compressor in the direction of creating boost which in return eliminates turbo lag by providing extra air pressure during low RPM. Almost instantaneous boost can be achieved by using a twin charged forced induction system.

Diagram of how twin charging works
As you can see above, the system functions almost as a normal separate procharged or turbocharged system but with the help of each other. The procharger helps the turbo create boost during low RPM because it provides extra gas needed that the motor can not produce by itself under low RPM load. Meanwhile, the turbocharger helps feed power to the prochargers and provide adequate air for them during high RPM. Basically, the supercharger helps the turbo at low RPM and the turbo helps the supercharger at high RPM balancing the power curve.
Combine this system with Nissan's all-wheel drive and this car will kill almost anything short of a 9 second car off the line. This setup is excellent for launch improvement by minimizing turbo lag. The twin turbo twin supercharger kit is available for purchase at Power Enterprise and utilizes the stock IHI turbo setup.
