M276 Weistec Turbo Upgrade
https://weistec.com/all/mercedes-ben...rade-m276.html
We’ve been waiting on this one for a while... looks like Weistec is the first one on sale.
Curious to see what dyno results would be and how does the tranny handle the upgraded turbos.

That said, makes little sense to upgrade turbos and not get the most out of it with a tune.

Mercedes c43 2017
Anyone have any info on this ?
Like seriously, we are 6 months later, no even 1 video on youtube 1 dyno sheet, 1 post on mbworld, what is going on with this platform ? Are we hitting the plateau of our engine with a stage 2 downpipe and tune ?
why are we not seeing intercooler upgrade ? Meth injection kit ? TCU tune ?
My guess our engine is weak... cant handle more thats why we are not hearing anything about it,
please someone contredict me... im getting fed-up with this far too limited platform

It all comes down to the efficiency range of the turbo. Just because it's larger doesn't mean temps skyrocket, especially if maintaining stock boost levels. The efficiency islands could, and probably are, much larger. At stock boost levels the temperature increase will only be a few degrees, and is probably within the range of what the stock fuel system can adjust to, and what the stock intercooler can handle. And at stock psi you will still get a bump in power.

There are a few things on this platform that seem to inhibit a large part of the aftermarket availability of certain items: The largest factor is that it seems (to me at least) that Mercedes buyers tend to have fewer buyers that have the same interest in modifying their cars, compared to BMW and Audi owners. The long-term potential profits are lower due to that lower volume and lower demand. Add to that, that it was only within the last year or so that there was an easy way to flash tune via OBD, so this makes it very difficult and time consuming to test and tune with upgraded turbos. And finally, properly designing and building an upgraded turbo is much, much harder than it seems. You can't just throw a bigger wheel in it, or swap out sides and then expect it to just work at making efficient power. Poorly matched components may not be as efficient as they look on paper, or over-machined housings might crack. It's almost an art, and not everyone can do it right. Ask anyone who's familiar with how Tony Vargas' half-assed R&D turned out on the N55.

Usually the stuff Mercedes make stock is better than what's necessary...ex people keep asking for a cold air intake....it's basically as cold as it gets as is.

I understand the frustration ya'll feel. I'm not covering for anyone or making excuses, I have no dog in the fight. That said, my understanding is that Weistec finished working on a compressor wheel upgrade for the 2017-18 C43 back in March, and it;s been available for purchase since then. Don't know why it hasn't really been advertised over here on this forum or why this thread wasn't updated. I have yet to see a single dyno sheet or even a 1/4 mile run with this turbo installed... I can only suggest contacting Weistec and asking about that compressor wheel upgrade or going to their website.

That being said a few of us on this forum have taken the plunge to get the Turbokits.com upgraded turbos for our builds. I learned of that turbo upgrade from Jesse first before AMR started promoting the weistec ones.
Knowing this thread is about the weistec turbos though, in speaking to Matthew at AMR, he stated they are installing the weistec turbos on two customers cars. Not sure if they are also on this forum but I agree with you all that it would be nice for them to share the weistec dynos, 0-60,1/4 times as well. So ultimately, we’ll have two groups of numbers for everyone to compare.
I’ll be posting the Turbokits.com numbers as well.
just my 2 cents

I'm considering an E450 wagon after losing our w212 E63S in the Houston flood last week. Does the 450 engine have smaller turbos than the new C43 rated at 396 hp? Is this the reason they were able to bump hp vs software? Any information on the internals difference would help as well. I've been searching but not finding a ton.
It looks like we have AMR, OE and maybe Eurocharged to go stage one software. If you go stage one only what can we expect at the wheels? Is it around 400hp or is that crank ratings. Thanks in advance for any help.

some claim they have minor differences all along the MY's - some claim they are the same.

Just talked to Weistec. I asked if they have real life feedback on the turbo upgrade regarding track, dyno and heat variances compared to stock. He said they are "close" to have the data and will let me know when he has it.

It sounds like either:
1. Nobody has tried it yet
or
2. The results are not good enough to share either due to incomplete development or the C43 is just a limited platform.
