Sure it dose.

However I did not realize it left out that this is on a Saab motor, not a Porsche. I thought that info came over with the quote but missed it. Apologies.

It is just a comparison of a smaller volume inefficient stock cast iron Saab header against a built equal length system that seems to display that less volume spins up the turbo faster.

This is not the last word in header design, just a point of reference as there are always other factors that have effect.

What is most interesting is the stock unit on the same motor made more HP early in the power curve over the built equal length system.

This is just a data point.
