Yes, they do.

Do you think the AAM intake manifold is worth it for a full NA setup when paired with your intakes, EPS throttle bodies, a tune, Z1 headers, test pipes and exhaust?

My guess would be no. No one with a N/A has put up any dyno numbers yet that I know of.

I'd wait to see how SOHO's manifold turns out. But from everything we've seen, the AAM manifold doesn't do much.

One forum member posted a dyno with it and a few other mods installed, but the numbers weren't superior to what a normal mild-full bolt-on Z would put up.

That's why I don't remember it. Low numbers.

NO MANIFOLD IS GOING TO MAKE POWER ANY OF YOUR NA FULL BOLT STOCK BLOCK CARS!!. Geeez sus

So don’t waste my time with the GTR manifold conversion?

Unless you’re going to TT your car, these manifold lose so much power with single top mount turbos.

Here’s an example get a straw and try to blow a piece of paper. (Velocity) now with the same piece of paper, get a paper towel roll and try blowing.

Correct. Elmo gave a great example. For a N/A motor. It's about balance between cfm and velocity. A turbo manifold is more on the cfm side of the equation.

So is there a noticeable difference between Stillen Gen3 or Admin given the extra $?

Maybe up at the very top but nothing worth the extra 150 bucks you're going to spend on admins intakes. If you just use google and look at all the dyno's before the 3inch intakes got so much hype the power curve it relatively the same. Friend of mine with stillen intakes ppe longtube and MVR ported uppper with race gas made 360whp on two different dynos. Up for debate, but i squared off against it and she moves out.
