Sticky created the thread Adding the N63TU twin turbo V8 to the 2014 F15 X5 xDrive50i makes for a 5300 pound 12 second SUV.
" Many people have likely forgotten this but BMW did make high performance SUV's long before the X5M ever went on the market. Back with the first generation E53 X5 over a decade ago BMW produced the X5 4.8is model which was the highest performance X5 in all the land. With 355 horsepower and 360 lb-ft of torque from the 4.8 liter naturally aspirated N63 V8 it hustled the 5090 pound X5 to 60 in 6 seconds flat and through the 1/4 mile in 14.5 second at 96 miles per hour.

How much have things changed in the decade since? The xDrive50i is not even the highest performance X5 available although until the new X5M hits it is the highest performance X5 available for the new F15 generation. It is roughly the equivalent in the model range of the X5 4.8is of a decade ago since an M model did not exist back then. In 2014 what this means is a 445 horsepower and 480 lb-ft twin turbo 4.4 liter N63TU twin turbo V8 powered 5306 pound monster that hustles to 60 in 4.3 seconds and through the 1/4 mile in 12.8 @ 109.

To put it another way, quicker and faster than every M3 produced prior to the last generation E92 M3. You could line up next to an E39 M5 at a stoplight and pull away while sipping a latte. That is how fast BMW's SUV's have become but notice that they have not gotten any lighter. This generation was supposed to improve in that area by a couple hundred pounds (according to BMW who somehow keeps overstating their weight loss) but when weighed it turns out it actually isn't any lighter.

Everyone will no doubt state this is very impressive acceleration and it is but there is one thing that old X5 4.8is did better than this new car. It went through the slalom quicker and pulled .83g on the skidpad to the 2014's .81g. It also stopped 5 feet shorter from 70 miles per hour. "

I might do a DIY guide for this, since its a fairly irritating issue to have... "

How do you find your Quaife on wet/icey roads, or hard pack unsealed roads?
If you do not disable the traction control (only the first step is enough), in tricky situations the ESP can jolt the back around because the electronics counter reacts the LSD's input.
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.. "
