AAM SPEC Plenum Space !DYNO RESULTS!
I'd like to make one more point here, not that this thread hasn't gone seriously off course. How many of you have put your car on a dyno? What did it cost? $50, $75 for 2 or 3 runs? What did you buy? How much horsepower did you purchase from that? None? Well then what did you pay for? You paid for the costs of that shop buying, owning and operating a very large piece of equipment, and the technician who operated it.
So figure the costs of a slab of quality aluminum big enough to make one of these things (and remember that even though most of that slab gets left on the mill floor, it still has to be paid for by someone), then figure in the hundred thousand dollars or so that AAM paid for the computerized CNC machine that makes this part, and Alex's time making each one. NOW factor in the value of the part via the performance gains it offers. All of these things together make this well worth the price AAM is asking for it. Just my 2 cents, but I'm hoping people see the logic here.
Peace out!

Why do you'll spend $800 on an exhuast when you can make your own for $200???
First you don't know how, you don't have the tools, and your not goin to but the labor into it.
$200 for 15 whp is great. $13-$14 a hp.

$200 isn't bad at all, I spent $550 for the Esprit power intake kit which is pretty much the same thing. When I have it installed I'll post any gains to compare $ to whp. If its the same $13 to $14 per whp I should get around 33 whp. LOL

precious...moments of my life...wasted...reading (well, skimming) all the complaining 
Seriously though, making auto parts is NOT cheap OR easy. If you don't like the price, nobody's telling you to buy it.
Thanks to all those who contributed *actual* INFORMATION to this thread and to AAM for taking the time and energy to produce this part in the first place.

You have too much faith in Nissan Engineers, lol. For all their farsightedness, it didn't prevent them to royally ****-up half of the car. It's not like the 350z is flawless.
Anyway, If something is not as expected, we all drive down there and gangbang them.
J/K, I think the spacer is a great move and Is very reasonably priced. I have lot's of faith in aam. Glad I got in the GB.

This guy is totally on target. I have always disputed the whole Crawford claim of air starved front cylinders. Do we really believe that in this age of extreme environmental and fuel economy regulation that Nissan engineers would intentionally allow 33% of the engine to be running rich? Until someone puts a multi-channel EGA on each exhaust header and maps the O2 content by cylinder over the RPM/load curve, any intake tweaking is pointless. Even if its true that 10% less air is getting to the front, Nissan has probably mapped the fuel to compensate. So if you increase the air to the front without an increase in fuel to those cylinders, you are lean and could be burning valves etc. Since a typical dyno only measures overal O2, the overlean cylinders would be masked over by the others. I would like to see someone do a full A/F analysis by cylinder on a stock motor. If the ratios are balanced (as I suspect it is), then its now a matter of trying to increase overall flow without upsetting the balance. That stock slope is there for a reason and its not to clear the hood.

So Ben, did you ever get down to AAM and get your Procharged Z one of these spacers? You have almost the same setup as me (I have the 9 psi pulley though) and I just purchased a spacer in the GB. I REALLY want to see what YOUR car does on the dyno, with and without this addition.
Also, I assume you'll need some tuning (A/F) to accomodate the added air?
Please let me know what you find.
Thanks!
