Ooopps....my bad. They look like similiar design, but the one you are posted is definitely nicer looking.

Looks as though even from a visual stand point I can see that intake doing very well under F/I and even N20 conditions.
Reason being, look at the nearly even flow patterns. If the "t" near the top is tuned well, I would be willing to bet it's worth quite a bit in just the fact that the individual cyl airflow numbers will be very close.
It seems to have nice long smooth curves to the runners, so it should have a very nice TQ curve through the midrange, yet not suffer in the HP department.
That is a total bonus that you can save the Factory stut brace, or another for that matter.
Only thing scarry about the other intake that is modified right now. Is that it eliminates 3 of the 6 mounting bolts on the top of the plenum. As well as has major amounts of welding done to it. Welding Alum = Heat. Heat and warp things, and then good a good seal can be compromised. If that top intake doesn't seal well, it can lead to a vacuum leak, and then a rough idle or a boost leak.
Is it just me.... or does somone need to polish their timing chain cover. Since that is the first thing you see when you open the hood. Anyone done this?

That's a sweet looking setup! 
Question... I realize figures may not be available for the Z yet... in applications on other cars, how much power difference is there with a plenum set up like this AND turbo VS. turbo with a stock plenum?
If there is a discernable gain, I might be willing to fork over the dough for the combination of extra hp and looks.

I agree with what you said. It looks like allot of time was spent on this intake. I hope that it isn't a one of a kind! I'll have my girlfriend write a letter to the company to see if there is any information available. I'll keep you guys updated.

If I may...
The "other" plenum uses over 15 "bolts"... the three that were removed were non-vital to proper sealing of the plenum.
As for the heat and warping... you're VERY right... the entire plenum is manufactored on a custom jig. Per EVERY single plenum that has shipped fit PERFECT. We've accounted for potential warping under extreme temperatures.
Thanks for your concern... as it was well voiced. Most importantly... rest assured the experience lays in the creators mind. The first car to run this plenum was his own... further proven it is running on several supercharged cars under a GREAT deal of boost. Zero problems.
