This is possibly the most simple setup I have seen that makes major power. Basically if you slam enough air in the engine with the fueling to support it, it's going to make power. Turbos is the most efficient way of doing this. People really want to over complicate things on a turbo car. The initial cost of parts are going to be expensive, but if you really break it down compared to a properly built supercharged car to achieve the same power, it might be a little cheaper in parts and labor to do it like this then a blower. With a blower, not all of them that I have seen make power like this, it's so hit or miss on the mods. You don't need fancy stroker, heads, cam with a turbo car. Just lots of boost and lots of fuel. The LS guys have been doing it for years and the new 5.0 guys have been doing it too.
