Who's Upgraded their Turbos
Hope the compressor housings are finished soon, excited to see them put together...
I’ll have to measure the inlets on the compressor housing when I get them back but the couplers are slightly stepped to fit to factory boxes.
Probably going for a matte carbon finish on the ZAC intakes and ceramic heat coat the turbo shroud to murder out the engine bay.
Still tossing up between fitting the WMI injectors into the compressor housing or the pre intercooler pipes, any thoughts???
Ahhh so they are using a stepped coupler for the turbo connection. Yea take a measurement if you don’t mind just for comparison.
Injecting the methanol is going to give you more efficient compressor map as if you have a larger turbo (without the lag) but it won’t help iats. You don’t want to inject pre intercooler either as the fluid will get trapped in the intercooler and the air will actually heat up passing through the I/c since it’s not as cool as the w/m air. Best place is post intercooler so the compressed air has been cooled as much as your heat exchangers can cool, then the meth/water chill it way more before the air enters the motor. That will give maximum cooling as well as an octane boost and most efficient iats possible in any weather condition.

I think with the M177 the issue here is space, if we were to inject post I/C the coupler is very short and goes into a 90 degree bend straight away.
If we were to inject at the beginning of the inlet manifold it would require removal I suspect to avoid plastic shavings from falling into the intake.
I initially wanted to mount injectors post I/C however both Yabeela with compressor injection and Weistec with pre I/C injection are showing great results.
Im not looking to invent the wheel or be the fastest just looking to have a tough 10 second street car so compressor for now I think it is.

We have (finally) committed to production moulds and making a few minor changes to make the intakes better (smoother internal and better finish).
I was working on heat shields over the weekend too

After that will be CAI, although we have NOT had the need (cue the HAI jokes) As the airflow through the engine bay is pretty descent. One thing we did notice when testing was removing the big seal around the rear of the engine bay to the bonnet lets a LOT of hot air escape. Makes your wiper arms pretty hot though
DM or reply if you have any questions.
Cheers,

Need to know what ID changes (if any) we are going to make this week. Trying to find that info so we can finish these moulds.
The Best of Mercedes & AMG
Is this the center section? 58mm inducer compressor wheel, 76 trim turbine wheel? It looks like 2 of those will cost you about $1.8k-$2k.
Yabeela's custom casting costs $5k?

Now can you find the right turbo and put the correct link? Yabeela is dual ball bearing. You linked a journal bearing. Add like double price.

2 dual ball bearing turbos from Precision look to be able $3.6k. How does Yabeela make the turbine + compressor housing, or is that straight from Precision too?
To answer you, they probably package it all to fit the new AMG engine while using a reputable turbocharger manufacturer for the parts that really require durability. How they do it is another one if the questions that who really cares. Just once again ask the guy who started this thread and 4-5 others who chimed in that also have them on how they performed, what kind of service Yabeela provided, how the parts went on (any issues so on), how long they took to deliver, quality, etc. That’s what matters to us hardworking guys and gals looking to go fast.
Was wondering if you were running into any issues or problems?
Are you limiting your power to not hurt the transmission or are you running 750whp on stock trans? Do you daily the car? Meth installed?
