No, this platform is dying because of a lack of capable vendors. It doesn’t need dumb money. It needs a sea of people with money to spend that hold vendors accountable and to high standards. The vendors need to actually engineer solutions and then bring them to market for fair prices while also educating the customer as to the reason why their product is actually a good product. This platform has been riddled with marginally engineered products that were sold for astronomical prices and conversely repackaged garbage from China...and the new customer base that bought their e9/8x for 10k or less and cant really afford the car buy that crap hand over fist. THAT is what has and is continuing to kill this platform.
Well you can write a letter to Santa and ask him because your wishing hard at best.
Anything that's properly engineered and tested is going to cost more than most can afford otherwise keep playing with cheap and nasty Chinese shit products as that's all your going to get.
No one is going to go make a product, invest tens of thousands of dollars to make a 5% profit margin and that will still be more than most can afford.
And there is people like yourself that ridicule vendors and that's why most don't even bother posting.
This platform is no longer worth pursuing as there is no money to be made.
The few have made it easy for vendors to move on to other platforms.

That’s the only accurate part of what you said. If this platform had volume, we would have quality engineered products at acceptable prices. The volume isn’t here.
And you developed anything for the n54 platform and sold it in volume ?
For the few I meant the few whining little bitches that complain everything is to expensive.
The only way you can turn over a small profit on this platform is to get things made in China and that comes at a cost of quality.
Many products made for the n54 platform apart from a handful are all made in China to keep the whining little kids happy.

"Everything is so expensive for my BMW..." goes and get china shit for cheap....
"My car keeps breaking..."
"My ebay china part broke"... Ends up spending more than if he bought the "more expensive" well designed part in the first place.
There are people like us who take the time, energy and money required to enjoy, experience BMW as it 'should' be experienced. I don't tolerate rust, dents, scratches, dirty engines, leaks, or any minor annoyance...because imo it's a BMW and it should not be driven like a hoopty. And if I buy an old BMW...which I did, and which will be show very soon on my BMW CHANNEL on Youtube... I rebuild it to factory condition...because that's what I do.
Then there are the wannabe children who don't respect or give a shit about BMW except for the status symbol. And they hear about how fast a certain engine is and they go a cheap e92 n54 and slap on some china turbos because they saw it on Youtube... then they curse BMW and say how they personally know BMWs are shitty cars because they had one that never ran right.
In short, if you buy a BMW don't be acting like a damn kid who doesn't appreciate it or doesn't understand what should be done to properly maintain one. You will only be giving BMWs a bad name with such ignorance and disrespect. At least this is my opinion on the matter... same applies to Porsche, Audi...etc. any of those high priced lux/sport cars. Don't buy one if you can't afford to take care of it. Just like, don't get a dog if you can't afford to take care of it. You just be a bad owner.
And these are the few that destroy it for the rest of us and why we can't get quality parts and the ones that are are super expensive because of the low volume.
I'm saying that describing the effect of thermal transfer by using a static body (which goes to equilibrium) versus a moving body makes absolutely no sense. Zero.
If we introduce a 100 degree body of fluid next to a 250 degree heat source and let it sit there long enough, what's the temperature of the body of fluid going to be? If we have a 250 degree heat source, and we run 10,000,000 gallons of 100 degree fluid by it in 2 hours, what's the temperature of the fluid after it passed the 250 degree heat source?
At the end of the day measuring matters. More importantly, understanding fundamental (simple I thought) concepts matters as much, if not more.
Just to be clear - I'm not saying there is no benefit - I wouldn't know. And if @martymil anecdotally observes a benefit, I'm going assume he does. That's got zippo to do with your comments - different subject.

Don't keep asking questions, say what you mean. Are you saying that there will be no differential and no thermal effects on 10 million gallons at 100 degrees flowing in 2 hrs? No measurable effects? In on that scale, sure.
If you are making this exaggerated example to support your dismissal of potential thermal changes from ambient and contact thermal conduction, then this is an inappropriate example. Because there are about 16 gallons of fuel that flow in about 1.5 hrs driving hard that flows through metal tubes sitting inside a hot engine bay next to hot metal in the case of metal covers.
So it is in this context that I say the potential effects of both ambient and contact based thermal transfer thru the metal tubing should be considered. Is it substantial? Probably not, just like wrapping my coolant hoses sitting next to my air intake charge pipe probably doesn't do enough to notice...still again, "everything counts in large amounts." Drop by drop the bucket will fill then overflow.
Anything in motion causes friction. The fuel being compressed and forced through a restriction would be a contributor. Honestly I really only made it through 2 pages of the thread. I do not specialize in fluid dynamics, but in the grand scheme of things yes every little bit of temperature reduction is a benefit but maybe instead of R&Ding some nasa like fuel lines...shoot a little meth 
That would surely reduce the temps more effectively?
Side note I like my painfully priced Vargas valve cover.

I love my cheap Chinese charge pipe and I'm sure so many other vendors do to because instead of making 5% there making more like 50% and they all come from the same couple factory's in china. As for fuel being heated up to a degree which you can measurably see the difference The only way I can even imagine this being possible is if you are over driving the hpfp. Otherwise I just do not see how this ever could be an issue no matter what valve cover someone is using. Not really sure why everyone hates chinese parts , If you don't see there value for certain parts don't use them. Platform is degrading because there's no emphasis in teaching these young bucks how to own and maintain a motor like the n54 properly.
No they dont, they make no money of it or loose a bit.
Getting it in, paying people to repackage it, shipping and credit card charges.
They will be lucky to make 10 bucks and then you have overheads like warehouse, insurance, electricity and tax.
There goes the 10 dollars and then some.
The money they make is if someone buys something along with it and then they charge you extra shipping
whilst it doesn't cost anymore to ship it.
On another note there is way more improvement to be made keeping the fuel system cooler which will help with cylinder cooling.
Cooler cylinder means less chance of pre ignition or missfires.
How ever small the gains are by doing small things they all add up as seen on one of my customers cars.
No overdrive, no fancy manifolds or turbos pretty basic stuff, just strategic mods that keep his car running perfectly making 397rwk
which most need some kind of extra fuelling which he does not just a stage 2 bucketed system running 24psi.
It is running on the edge but holds up well without any issues in our extreme conditions for the last 12 months.
A well respected Melbourne tuner never seen this before and is astonished at the results he is getting after we done the mods that are needed to be done.
He is smashing and upsetting a lot of people that spent 2 to 3x the money on their cars and he is running in full street trim just about.
And its all in the fuel system mods nothing else and they are nice simple ones that get rid of restrictions and heat.
It is sad to see quality performance manufactures suffer because of the Chinese mass produced lesser quality copies.
Might be showing my age but I noticed this trend back in the day when the Walmart’s basically ran all the mom n pop shops out of business, and big business outsourcing their products to fill their pockets and giving away all that development.
Yeah way off topic even though this post has somewhat traveled the gambit. Lol
Here is something I been researching maybe too long today...I am wanting to incorporate a MAP sensor to maybe a arduino for monitoring/and maybe log crankcase pressure to possibly track engine health.

There's a good amount of companies just straight up drop shipping items from China. It's extremely easy to do I could do it if I had enough money to invest. Contact a supplier on alibaba have them engrave your company name order 100 sets at say $45 sell them for $140. Pretty sure there's money to be made somewhere between there. That's just an example of charge pipe there are still many other items such as Intercoolers that all come from China for the most part.
Any individual can get a charge pipe for around 60 bucks shipped of ebay wheres the profit you speak of.
The profit is in mass quantities it’s like say a Toyota dealership sells exorbitantly more lower priced cars than say BMW or Mercedes. Mass quality leads to profit. I know using Toyota as a example isn’t exactly a perfect example cause they do build reliable automobiles.
It’s the same as big business the accounting departments and executives could care less what product the engineering department makes in my case I work and develop oil field equipment wellhead systems to be exact. After our initial R&DING testing and certification they pump that stuff to China for manufacturing...years ago we had manufacturing facilities all over the State’s. Pre-covid we were down to just one facility in Houston manufacturing since covid that has been permanently closed. I am one of the lucky few that is able to remotely work from home. In just that one example the company I work for had 10-15k employees it’s down to at best 500-1,000. Some of that is due to fluctuations in the industry but the same logic is applied to the majority of industries.
Ok yeah that was a bit of a standing on a soap box story sorry for all that suffered through my ramblings
We are talking about the n54 dying market that's getting flooded with cheap nasty
China parts and there is no volume like there was 5 years ago.
The platform is riddled with nasty crap getting pushed on us as quality and then
when someone actually brings a quality part to the platform, it gets compared to
substandard Chinese knock offs because its not the same price.
This is in no way an attack on Chinese people as I have many Asian friends which are good people.
The problem is you get what you pay for.

Agreed our platform is not as attractive for company profits...unless the company itself is actively using the platform.
Side bar my statements were not to infer I dislike chines and or any ethnicity group for that matter. It’s a example of how the majority of business decision makers have placed personal profit above pride in products and supporting economic growth.
