A forced asperation setup using a turbocharger and a positive displacement supercharger.

Advantages are no lag and boost in low rpms (via the supercharger) and high boost in high rpms (via the turbo)

similar to a turbo shandy, containing strong lager and smirnoff ice, but has the added bonus of two shots of vodka in a twin charged shandy. not to be confused with a turbo shandy with boost which only has one shot of vodka with the smirnoff & lager
