I agree. Crank driven blowers take crank HP to run them. Turbos mostly use power that is escaping out the exhaust. In our engines a very large percentage of the energy created by the combustion of fuel is heat that is wasted and causes over heating and exhaust gas issues. Turbos use some of it to make power while crank driven blowers add to it. On inline engines the turbo manifolds mount the turbo close to the engine and have a single outlet. If you want duals you could split the pipe after the turbo. That said a 4-71 or a McCulloch on a Jimmy is a cool thing and works very well.
