Honestly hasnt even crossed my mind. There is no such thing as a power rating for an exhaust manifold. The engine feeding it and the turbos behind it far outweigh the design of the manifold itself when there are no obvious or questionable bottleneck areas or size restrictions. I already know without any flow testing that these manifolds will support more power than any turbos that are likely to fit on the side of the engine without cutting into the chassis. Unless you are talking about over 1400 rwhp (where we might step up runner diameter), Im not sure there is much conversation to have about a limitation.
