Turbos produce their power in a gentler area of the piston p/v trace so they're going to be inherently better on the bottom end, and they're also more efficient than a supercharger in terms of parasitic loss. That's why there are so many stock block turbo LS's making 1200+ to the wheels. If they were N/A or nitrous motors they wouldn't live. You lose VE with a turbo because of the backpressure increase, but they don't require physical hp to turn like a blower. Prochargers make good power, but are fragile in comparison plus put additional load on the crank, and they are both easier on parts than nitrous.

If you are willing to embrace EFI and can fabricate a turbo kit, they're the best power adder out there, especially for drag and drive type events. Many of those cars have bolt on turbo kits available, so you don't even have to do any hard fabrication to do a turbo LS in a Mustang or Camaro.
