Descendant intake manifold
Only proof for what it will produce is dyno the car without the manifold, don't undo anything from the dyno leave it secured as it was first few runs, then install the intake and redyno. Same with the turbo kit do a dyno with just the turbo kit installed and tuned, then replace the intake and redyno.
Do the dynos without changing anything on the dynos or security straps before the intake and after this will show true numbers and not bs.

I have done it and it take about 3-4 hours to get the intake manifold out and switched. There are two bolts below on the factory intake manifold besides the ones up top. One of these bolts is a big pain to get off, using a wrench was the best way to get it off I found. You also need to take the fuel rail off, vacuum and coolent hoses from TB and other odds and ends. Other then that it is not to bad, just don't try to force it out, take your time and take off what needs to come off.

I like how people are telling them how to dyno.lol I'm sure they know how to do it.
Give them time peeps. I'm sure they got a ton of things to do with the race team. The only down side for them not getting the numbers out fast is it might hurt sales.

Nope...only difference is the vacuum ports we added during the first production run to simplify the install. The first manifolds they made were ALL RACE with no ports for OEM sensors / vacuum sources. Anyways... other wise it was the same manifold. However ever since the launch of our DESCENDANT product line Golden Eagle no longer offers them direct because it's the DESCENDANT / WORLD-Racing design. Same deal with the fuel rail...the manufacture our design.
Actually people are more interested in a dyno that consist of a completely bone stock tC and the intake manifold. Then a turbo tC and intake manifold. There are too many variables to consider when doing a dyno with I/H/E.
