The absolute cheapest Intake Manifold I could find online, want some thoughts on it if anyone has tried or even seen it before.

I’m all for saving money when you can, but a $3,000 extra manifold versus a $20,000 block and rebuild is not a place I would personally try saving at, without imperial data showing me there’s no difference on multiple hot lap tests.

Ok fair enough, as you were. You are adequately qualified to speak on this and you are doing a great service to the members of this community by providinf them accurate and factual information for them to make the correct decisions.
Let's break this down, since you're new to the internet

-I tell OP in the beginning, either choose a Wagner or EOS since both are proven
-You defend OP's manifold with a massive secondary indent on the plenum and said, "There is no reason to return it, it works."
-I sarcastically erred on the side of caution with certain concerns, and possible issues.
-You then asked a godzilla avatar, shitposting burner-account "What do you do for a living? lol" your mic-drop moment was supposed to be "I own a shop," "we have data," "we have world records"

The following posts proceeded with......
-No data
-No data
-No data
-A possible picture of OP's manifold that I can barely make out.
-No data
-No data
-Razorlab with data
-No data
-No data
-No data

I despise Instagram marketing but forced myself to look through that page of slop and THIS was all I could find to see if it was OP's manifold.

I genuinely want to give you the benefit of the doubt here.
We are talking about the OP's specific manifold, correct?
You aren't just confused and are talking about "Chinese manifolds" in general, right?
Because there are some very good Alibaba manifolds out there.
We are specifically talking about the OP's specific manifold that has a specifically large secondary indent on the plenum............and as a shop owner and a CFD expert, you are completely fine with installing that on your customers cars at that very high horsepower level?

Anyways, I've had my fun. I'll be waiting for the marketing or damage control data that he'll post one day.......... but hopefully this is the start of razorlab's comeback lol

As much as I wish that we can make this place enjoyable enough to where Razorlab doesn't have to burst a gasket every time he logs in, it is fun watching someone filled to the brim with knowledge go to town on people who know way less than they think they do.

This thread has shown me the people who think they know stuff actually don’t, vs people who just don’t know what they are posting. Without actual pressure drop differences from one side of the intake to the other, everyone is just guessing that it sucks. Chances are, in that aspect of things, it’s just fine with that lump built in. Everything else about it might suck though.

Ok fair enough, I am talking about the OP’s original intake manifold, which is from Phoenix racing. The same one that burger tuning and fuel it uses. Forgive my ignorance. I blindly assumed all the Chinese manifolds were made my Phoenix. But I am referring specifically to the Phoenix one, of which we have installed 5. And they all for cars that are drag racing. I have no data for circuit racing, those customer of ours are running CSF, Wagner and EOS.

I had the feeling there was some type of confusion going on between us. I apologize my dude.
I looked at the Phoenix Racing manifold, and it looked almost the same, but that massive indent is practically gone and that plenum looks a lot more smooth.
Does OP have the first-gen prototype? This is a headache to find perfect photos of these Alibaba manifolds. Do you have any photos of them with better angles?

Not this fucking shit fuck stupid forum.

Not a Corvette.
Actually... the Phoenix Racing manifold doesn't look like the Burger one at all. Coolant ports are totally different, the front connection is different, fuel rail connections, Etc. From the photos on both sites, not the same manifold at all. However, the one that BimmerNetwork sells for $2,200 is def the 1:1 exact same as the $800 Phoenix one. (The one in the photo below is a gen 1 so the Evap connection is in a slightly different place). Seems like Phoenix also has about 5 variations of their manifolds for Gen 2: All cast, CNC, Evo, Evo Max Core, 48V.

Evo Max Core seems like the most promising one but might have fitment challenges since the core is large. 48v version is to fit the mild hybrid models like M340i, etc

Problem with the Evo Max Core version is that it looks like they sell for around $1800 or so. At that point, just do a Do88 or Wagner.

i asked Burger and they confirmed it phoenix, tey have a ton og other Phoenix stuff on their website as well. Phoenix has 3 types, CNC, Cast and half CNC, half cast,, so I'm not sure which one Butger is selling.
