I got an interesting reply to my email inquiry to FSR. I am posting it here. I looked up CFD. It means Computational Fluid Dynamics. There's a 10 cent phrase for you.
When they say "no correlation", I would like to think they mean "not necessarily a direct correlation". Otherwise, why bother with flow bench at all?

Hi Dave!

We are hard at working on solutions for your S54. We'll get back to you as soon as we can.

The manifold will get adjustments via CFD and we have the facility to flow bench it. However, we've been building and tuning motors for ten years and on a turbo car flowbench results do not correlate with horsepower/dyno/track results in most cases. We use 1.5" primaries in cars that make 1500whp so we're confident in what we're doing.

Our concern isn't anyone else's manifold, but that ours is as good as it can possibly be.

You better believe we do a lot of testing, that's why they aren't for sale yet!
