" Sticky, can you detune the rep spread count again to 10?
With 20 I get Must spread rep so much I can hardly rep anyone anymore.
There are hardly 20 different people on the forum worth repping...
Or better, let the rep count decay with time. As they disappear in 3 weeks or so from the rep count... "

You'll get used to that (strangely only happens on wet roads going uphill), or do as I do, and disable traction control and enjoy the LSD more (hail to the JB4 option which disables this for me automatically!). That will make the car a lot more predictable.

I uderstand the reason for your last question, but for me the Quaife has never let me standing in slippery conditions
In winter conditions I have winter tires so I never encountered a situation where I had no traction at all on one wheel.
In fact having a LSD in snow is quite fun. "

" I am on the stock fluid and the level of noise you described is what I have found to be the norm. It doesn't get noticeable until I am in a drive through or the ac is on. It is the same noise that all manual bmw's have when they shut off and the clutch is out. It is most likely a spherical ball bearing that is causing this noise. "

Sticky replied to the thread Article: Trap speed vs elapsed time in the 1/4 mile illustrated by M157 AMG's, one rear wheel drive and the other all wheel drive.
" By now you are well aware that Mercedes offers the 4Matic all wheel drive system for the facelifted CLS63 and E63 AMG models. So what happens when you put the pre-facelift rear wheel drive 63 AMG model up against the facelifted 4Matic all wheel drive model on the dragstrip? Even a casual automotive enthusiast would likely guess that the result would have the all wheel drive car showing the quicker ET (elapsed time) whereas the rear wheel drive car would have the higher trap speed.


That is usually the case although by no means an automotive law. It is what happens in the drag race below though and that is partially due to both cars wearing street rubber. Soft drag rubber is pretty much a necessity for a high torque rear wheel drive vehicle to get good traction off the line at the strip.

Now, this is not exactly apples to apples as the C218 CLS63 has an ECU tune. The W212 E63 AMG S is stock and an ECU tune makes a huge difference in power and torque. Combine an output increase as a result of ECU tuning for the CLS63 along with its roughly 200 pound lighter weight and it is no surprise it traps 128.72 miles per hour to the 4Matic E63 117.83.

A difference of almost 11 miles per hour is huge and using the old rule of thumb of 1 mile per hour being equal to 10 wheel horsepower without even seeing the dyno numbers of the two cars we know the CLS63 is putting out roughly 100 more horsepower at the wheels. A trap speed is often as good as a dynograph. "

We checked the plugs and the number 6 was darker than the rest. i remember in a previous post i mentioned that the number 6 TB coupler was pinched and i had a massive leak. I think the cylinder was not getting enough air and thats why this happened. Replaced all and it seemed to be fine after the test drive.

The next day when I went over and started the car to warm it up for another test drive I could feel the misfire again.
I swapped coils 3 and 5 (misfire indicated on GT1) with 2 and 4 and then checked it again. Now it showed misfire in 2,3 & 4. Meaning its probably the solenoid.

We'll swap it with the BEISAN re-manufactured and improved solenoid and report back ASAP.

" Interesting evening. Spent all day trying to figure out why changes in ATR were not doing anything. Handheld Cobb data not matching data log data and that didn't match ATR inputs. Guess it's happened to others, advice given to me was uninstall AP manager, ATR re install, in flash and re flash car. Trying to do all that now but car battery did not want to cooperate. Recovery mode, jumper cables blah blah. Will see if it fixes the problem tomorrow. "

Xyruss replied to the thread I need help...
" im just confused because when I first installed the sensors I can confirm I did it the correct way (both O2s with the grey shealth on the shorter pipe, at least form what ive read), and my car immediately went into the rough stumbling idle and misfires when I started it up. so then i swapped them to see i had it right the first time

its not like those sensors would be getting any different readings than they would with stock downpipes since they are pre cat, so i dont know what to think about my results from the first install . im gonna swap them again this weekend and see how it goes I guess.. "

I personally went with the Whiteline kit and can report that it improves rear end feel, stability and traction. I test my car on the mountain upon which I reside- I don't have to push my car to notice the difference.

Considering the whiteline kit for my diff. Wish I would have known about them before I jumped on the M3 subs. Rear is still too wiggly on hard accel. It's gotten a bit worse so I'm assuming my stock diff bushings are about ready to be replaced. "

Raise the car, move the suspension around and listen for the noise. Move the wheel through its travel, turn steering wheel etc.

You can do this at home with 4 stands and 1-2 jacks.
Thanks Ryan,

Yea, will be messing with it this weekend again checking all the torque specs to see what I can come up with. Something is not right and it's driving me nuts not knowing what. "

V8Bait replied to the thread self tuning : BB flash or Cobb.
" I didn't say they were the same, I said outcomes can be virtually identical. It really depends on goals and setup. I'm well aware of the handful of changes they've made, they are very useful to those who need them. Cobb engineers are good at their job But not everybody needs the extras. I'm a supporter of Cobb don't get me wrong (owned one on two cars) but OP has a jb4 so many of those added lines of hex wouldn't even matter for him since many changes are for boost response and boost up high afaik.

End of the day Cobb is superior but results are results. If I was OP I'd download both and poke around. "

I win the event and it's 'oh the S54's weren't running right.'

My car shreds a belt and now it's the S54's dominate and some guy with hundreds of whp less that lost last time when my car was running at the same time as his is the world's fastest.

Did you have anything else to add? "

Sticky created the thread Car and Driver gets the quickest and fastest 2014 991 Turbo S Magazine numbers so far - 10.8 @ 126 1/4 mile.
" The 991 Turbo S test numbers are perplexing to say the least. MotorTrend managed to get a 10.9 @ 123.7 1/4 mile sprint out of the car. Road and Track essentially mirrored this with a result of 10.9 @ 124.4. Car and Driver now gets into the mix and their acceleration numbers are the best of the bunch with a 10.8 @ 126 1/4 mile elapsed time and trap speed. Their timed 0-60 run for the all wheel drive Turbo S comes in at a blistering 2.6 seconds.


Even though a 10.8 @ 126 is the quickest and fastest of the three major US Magazines these numbers still are slow. Independent drag strip results are better with a 10.68 @ 128 pass on the dragstrip. Car and Driver, Road and Track, and MotorTrend all get a result with the more powerful 991 Turbo S that is closer to the standard 991 Turbo. The standard car at PBIR (Palm Beach International Raceway) in Florida ran 10.9 @ 126.

So what is the deal? We really do not know. Maybe the cars pull timing due to aggressive software. It would explain why dyno results seem to vary greatly pull to pull. The spread shown on an all wheel drive Dynojet is up to 30 wheel horsepower and torque can change by almost 60 lb-ft. Heat soak, software, timing, whatever it may be something is causing inconsistent performance with the 991 Turbo and Turbo S.
