I would think you'll heatsoak the CP to the same temp since you'll have no thermal barrier between the head and the CP with a metal IM, no?
aftermarket intake manifold - what are the benefits?

Because the charge pipe is right next to the fan and its pretty thin it doesn't absorb heat like the manifold
Its also in a direct airflow path from the fan
Plus it gets cooled quickly with the internal airflow from the ic especially when the car is moving
At low loads definitely you can see from the log the temps sit a few deg higher but once you nail it the temps just drop

You're also assuming a ff manifold. The manifold will stay hot longer than the cp, sure, but if they're both aluminum, they should both dump heat into the intake air at the walls at the same rate given the same flow velocity.
When the manifold is heat soaked you cant touch it but the charge pipe you can quite easily and you can leave your hand on it for quite some time
Must be because of the thickness of the material
Its just an observation, could not be stuffed measuring it
In my case it doesnt affect performance but im getting the dome done in carbon fibre to reduce weight from 12kg to maybe 6 to 7 kg
Its only a guestamation but its going to look much cooler and will definitely retain far less heat with a huge weight saving.

Custom plenum creations are releasing a carbon fibre IM soon, in the next couple months I’m told. It will be available through VAC. In fact I think they are based in OZ
I've been helping a local shop develop one for the last 6 months, should have a complete sample in the next few weeks ready for testing but its going to be a pressed sheet metal manifold, its a ram tube design so should help lift the power in the top end.
weight saving should be 5 to 6 kg over the ff manifold and reduce heat soak drastically and it will come with an optional charge pipe to suit single, twin and tft style turbo applications.

This is exciting. Hopefully it doesn't carry the VAC price tag.
You know what manifolds don't heat soak? The stock ones. Still waiting on someone to show actual proof of a better manifold for this platform. Sure some of the aluminum ones gain up top, but if you aren't revving higher what's the point?
think the waffle serves a purpose other than sound dampening? I'd be pretty interested in n insert to covr it, such a pita to clean.
This is a damn good idea. You could have some sort of logo imprinted on it or some text. I'm gonna add this to my list of things to 3d model, maybe someone will beat me to it.
You could make a bolt together carbon clamshell piece that would add some strength and better looks...
That would be awesome. Even sheet metal would be fine. Just don't sell the idea to VAC. We'll be paying $2000 for it.
Do it! Flat black plastic insert clipped into the waffle would be perfect. Make them stamped with ///N54 or something. You'd make a killing as long as it didn't fall apart like the BL coil plugs lol.
I guess...It's bolted to the engine so stress is not an issue. Any quality made manifold is going to add about the same unless you use composites. Which could honestly increase the price. Something this platform does not like
but I guess if you are chasing high hp numbers and need an intake manifold like this you are already past the point of no return.Something like this for instance obviously designed for our inline six: https://www.amsperformance.com/cart/alpha-performance-r35-gt-r-carbon-fiber-intake-manifold.html/
