Hey Zoog,

You are comparing apples to crabapples. They are both turbos but they do not flow the same amount of air at 14psi. The CFM is significantly different in terms of volume and density.

You are going to need more fuel, and less fuel in places. The single needs fuel in different places than the twins. Not to mention that lighting that fuel is different. Even more different if you're talking a ported engine.
