This isn't an answer per-say, and I'm not singling you out whatsoever, but it's clear in the dyno that this comparison is not "bone stock vs. bone stock with a manifold", that's not the point of it.
There's a simple, overlooked truth to intake manifolds that has hindered companies, and individuals from making them, or trying to sell them, and that is the fact that most Z/G guys insist on seeing an intake manifold that they can just slap on their car and gain massive power.
Well, the truth is, that an intake manifold swap (aside from a spacer) is generally something only done by guys who are going to, at minimum, have at least an extended RPM limit, if not headers, long tubes, cams, and so forth.
The engine is one big pump, it's not a calculation of a + b = POWAHHHH, it's a + b + c, and so on. You need the whole thing. If you have an intake that flows awesome, but it's choked off by our tiny little throttle body, or by the stock exhaust and cams, you are never going to get anywhere.

OP, I greatly appreciate your answer to my question. The stock setup is quite restrictive.

My engine is built NA. and previously made over 370whp. Its quite restricted and dying for air, and maybe for less exhaust restriction as well.
Everything needs to work in harmony to make power.
This is just proof that these mods do work to allow more air into the engine.

the Carbotron plenum was made before Sasha hacked up his OEM plenum that 2TH PWR now has...
From what I gathered & remember from the discussion was, it wasn't strong enough and would need to be reinforced ....
the cheaper way was to tweak the stock aluminum upper plenum.

Here is something that maybe an older fart like me can add.
Back in the late 80's when the EFI Fox Mustangs started to roll out onto the streets we thought that would be the end of tuning.
After a while people started putting out aftermarket parts for these little engines, and things started looking up.
Anyway, there really wasn't any stroker kits back then unless you made one using various parts from other engines.
So the problem became trying to run these little cid engines on the street at a sane RPM with the ever bigger heads that were comming on the market.
We found out that the super long runners in the stock intake worked great with heads that would otherwise be too big to run on the street without having really low rear end gears.
So IF possible I would try to build an intake with runners as long as possible, but also as large as possible.
This, in theory, should give you decent low end torque, and high end HP, with some really good ported heads, and good camshafts.

I would be VERY interested to learn more about this Intake setup and its availability!! I would also be willing to put the $500 down to get this started if there was a reasonable turn around time.... Please feel free to PM me if yall do in fact to do another one of these!! In 90mm Form though, Please!
Thanks,
Jonathan

the project of replicating this intake and hopefully some tweaking to it will start in the next couple months.
I plan to make 2 to start which one is already sold.
The rest depend on the real interest from you guys.

Another interesting lead.
And then polishing it might help. You can also try extrude honing the neck.

Unless I'm missing something he chopped off the stock neck and grafted some aluminum pieces on it to make a larger opening and then welded some 3.5" pipe to it and built the rest of the intake. It couldn't be reproduced in an hour but a solid day or two and it could be.

the inside was also gutted out. very interested in looking for a shop to try and replicate this. maybe say its for the z community
