M6 runs 10.3 on stock turbos

https://instagram.com/p/BMb1pIyhN__/
kinda disappointing that this M6 makes 773 whp/ 857wtrq weights 150 lbs less and only trapped 134mph when AMS kits makes about 100whp less and traps 1 mph more.... and I'm not really impressed with the AMS results to begin with otherwise i would of bought the kit
still waiting on updated results from wesitec W4 or pureturbos kit (think eurocharged is doing the tuning), but if results arent great then i will just save the cash from turbo upgrade and put towards 991.2 I'm thinking about getting into

This was just posted. Not quite a 10.3 but the trap is up there with which look like stock turbos.

even if you want to stay "german luxury" there are audi TT's running in the 9's and trapping 150s for 1/2 the cost of M6 ... but again different carsi would love to get in the 9's for cheap on a MB but just isnt going to happen with a off the shelf bolt on cheap kit... not a big enough market ... i would also like to get a lambo huracan for under 100K and UGR huracan turbo kit for under 50K, but market wont support that price either

and there are tuners out there getting great times out of M157's , they're just not US tuners.... bmw/Audi has always had a bigger tuner market in the US than MB... you want to push the envelope on M157 then look outside of US to PP-performance, GAD, Poseidon, etc

blame MB on giving us tiny turbos under the engine instead of bigger turbos in the valley of the engine like BMW did

Let's look at real numbers. That E63 that was posted earlier in this thread on dragtimes ran a 10.6 at 133mph. Let's see some numbers for some of the turbo upgrades we have available (not the GAD cars because they are way beyond just a turbo upgrade). They are pretty much the same thing. How come? You're upgrading turbos and you're yielding about the same results as a stock turbo car?

you are also forgetting that s63tu turbos are twin scroll, ours are not so even if we run the same boost the BMW turbos are going to put out about 20% more HP... why you think new e63 is coming with topmount twin scroll turbos ?

Ok, this is good... we're going down the right path.
1) How do you know it's only a turbo upgrade?
2) How is this different than what the tuning companies here in the U.S. offer? They can all buy the turbos and slap them in, but there's some key element missing, and that's tuning.
My point here is, let's stop supporting and buying into these products that are not proven. Yes, we all get hyped when a new set of turbos (or turbine wheel upgrade) is posted here, but let's all just wait and let the companies do their R&D and show us what their mods do (with their tuning). I hate to keep using this example, but with the GT-R it was simple. You buy certain kits, you run certain times. You know what you're getting into. I feel like with our cars, you really don't know what you're getting into and the excuse is always (well, limited production)... that doesn't cut it for me.
I have seen them fail more than success...
Anyone here got it done right ?

Yes having a turbo that is too small is a handicap for this car, just as not having a way to bypass the torque limitations. Other platforms having twin scrolls cannot be looked at as having some form of undue advantage cos they also have much smaller displacements. It is what it is.
Aftermarket turbos on M157s should be able to close the gap but alas they are not (in the time being).
Maybe after tuning is fixed, we will not need larger turbos to do what BMW does. We might be able to do it with a lot less RWHP (but with boatload of torque)
for us to be on par with them we need to be able to run about 28.25 lbs of boost when they are running 30 psi

My point is this is what you bought, this is what it came with, make the best of it or switch. No sense in *****ing about something (hardware related) that at this point you cannot change for that much better.
Software on the other hand I believe could be much much better (Speedriven! any chances of a standalone on this platform? I will try it just to see how it does).
