For you that may be an issue as you live up top, but many of us would enjoy the larger mid-range gains. Area under the curve = fun. I would like to see unbiased dyno information tho.

EDIT: You will most likely have a different result as well.... apples to apples

 

It may be hard to believe, but might understand a tiny bit about which area of the curve is fun.

But this was marketed as having been engineered from the ground up to provide superior flow than the stock manifold. If that were truly the case I would imagine that entire curve would be shifted in every section, especially at the top where there would be the most pressure.

Who knows, maybe the manifold could be pushing more flow than the fuel system could handle? But, if these truly made the power I'm sure we would've heard about it in a big way as opposed to someone randomly finding an excel chart on their website..

 

Amen to that

 

i wish they would let me borrow one for testing.. i would compare it to my stock ported and ported VQ35HR manifold..
i offered to due it on my dime and film the results of each one..
haven't hear a peep from them

 

Yea I read that... possibly @370Z.com. They also had testers tho no? Didn't the NA guy stop testing for reasons unknown or he couldn't get good results?

 

as far as i know no one has tested N/A i PM'd and emailed them directly but heard crickets..

Early Easter Egg- New AAM Competition 370Z/G37 Product! - Page 5 - Nissan 370Z Forum

I wanted to provide you all with some additional background info concerning this project.

We ran into some issues with the intake manifold, which took us some time to overcome. Many of these delays are attributed to the casting process. The first limited batch of intake manifolds we originally received for testing purposes were terribly inconsistent in terms of their fit and finish. They did not live up to AAM Competition’s quality standards. The cast manufacturer had told us that this particular mold was extremely difficult to work with. Our engineer made some minor adjustments to the CAD design of the manifold to make the casting process more efficient and accurate. In order to implement these changes, the manufacturer then had to create an entirely new mold.

Once the new mold was completed, a new limited run of manifolds were put into production. After the revised manifolds had arrived, we could resume evaluating the units. These manifolds were MUCH more consistent, which definitely made our additional effort and investment worthwhile. During quality analysis, we quickly discovered that many of these intakes were not holding pressure. Ouch! ….. yet another hurdle to deal with. We promptly coordinated with the casting manufacturer to discuss this problem, ensure that a proper solution was put into place for production, and ordered yet ANOTHER set of intake manifolds.

All of that said, we’ve FINALLY received a limited run of manifolds which are not plagued with the prior production faults. With this batch, we were able to further review and analyze the units as we intended them to be. Dyno testing on a high power, high boost twin turbo 370Z (the type of application we designed the manifold around) proved a peak gain of 36whp/34ft. lbs. in the midrange! We are very pleased with these results, and look forward to pushing the manifolds even harder to see how they perform.



Although we do not anticipate significant gains for NA applications, we will be performing NA dyno testing as well. The AAM Competition VQ37 Performance Intake Manifold was specifically designed with high power forced induction in mind. For naturally aspirated vehicles, this will be primarily an aesthetic upgrade, with the added benefit of being much more durable than the OEM plastic manifold. I'll be sure to post these results here as soon as they are available.

 

if u not over 14 psi of boost... getting the gtr GTR manifold would always be for aesthetic purposes... over 14 psi you can crack the plastic due to pressure...

 

So, not sure how many people are interested in this, but I feel obligated to disclose what I was told in order to save some people cash and time if they're waiting in this. I work near aam and have a close friend who works there. I saw this thread picking up popularity and decided to ask him about it and see if I can get the scoop.

He said the following and quote:

[The] manifold is some trash!!! ...[B]arely put any R&D into it and tried to rush it on the market. **** is actually losing HP...Hence why no dyno results were ever posted."

He's not a disgruntled employee and loves what he does. He has nothing but good things to say about other products offered by aam and isn't the type to lie or exaggerate when it comes to the aftermarket. I know aam doesn't have a great reputation but if he was ok with working for them and will vouch for their current work and employees (except the tuner....apparently there's a lot to be desired there), I'll let them turn a wrench on my car any day. Take it for what it is but with that opinion, I'd look elsewhere.

 

"I got a really special tune" Is this tune for your NA application or not? and can you provide the forum with substantiated evidence........

Any news on aam’s manifold on NA cars?

 

Get the Z1 or the ported 35HR.

As stated before, I have a friend who worked for them and was there during the manufacturing and testing of the aam manifold. Not only does it cost them pennies on the dollar to make, the cars they were being tested on were losing power. That's probably why no one heard back when independent testing was going to take place.
