lol stock turbos don't make 760 wtrq in the real world ... on an inflated corrected Dyno maybe ... or maybe for a split second Dyno spike
and stock turbos only make high trq for a small rpm with window and then run out of breath whereas bigger turbo holds that trq to upper Rpms thus higher hp
these bigger turbos should make it much better for highway pulls but still do nothing for low end launch.... so you will still get smoked by m5/ RS7 at the stoplights
Here is mine... Stock turbo and hanging out in the mid 700's for torque not just for peak spike. SAE. So not sure what you're talking about real world and what not. Not to mention when people post numbers they are going to post peak so idk what the argument is there? 700+wtq from 2500-4700.

For an awd car with this much power, these are about the worst there are when it comes to launching so I can see a lot of rwd cars doing just fine at stop light races against the E63.

maybe some can, but the m5 is absolutely terrible with wheel spin. I would say it's easily much worse at launching off the line that an AWD e63s with a slight half second lag, still hooks up better, plus look at its low-midrange torque. After 60 is a different sorry as the bigger turbos and RWD will have its advantage there.

I wouldn't say an M5 is absolutely terrible with wheelspin. In 40 degrees, regular tire pressure, out on the street (not prepped at all) I ran 3.77s 0-60mph on my vbox without launch control. You have to be a bit more judicious with the throttle in first gear, but the stock 295s and M diff are pretty good at hooking. My best 0-60mph in the E63 S in similar conditions (same section of road) was 3.36s.
Edit: I looked back and the 0-60mph was actually 3.67s for the M5.
The question on your time for the e63 is does the measuring tool take into account the slight lag at the start or only once car starts actually moving?
also, did you achieve that time only with launching or just by hitting the gas normally as you would from a stoplight?
i still think in most cases the E63 will beat it from the stop, not saying the m5 isn't fast, just that e63 4matic despite its softer launch still has a better takeoff/traction in most cases from a dig

real world, as in a sedan like our with 760wtrq should trap way more than 128+, that's what i am talking about... heavier rs7's with much less wtrq are doing 132+ all day, while all i see is mostly 128 traps from our cars (with the exception of the precision car with meth/custom tune= not pump gas power) ....
dyno's dont mean much other than finding a delta on same day or tuning tool
760+ wtrq graph doesnt mean much when it gets beat bad by heavier car with less trq.... its like having a 14 inch PP that doesnt work

But a 14 inch PP is still worth the look!
I'll see what I can do this year. But I think there are some things such as brake boosting that can negate what people have found so far. I just don't want to stress the tranny to much. But in the name of SCIENCE! I will grenade my tranny if I have to haha
Probably the tcu torque limits holding back too much power in the lower gears.
it seems that because of those limits getting in the way, the e63 from a roll actually performs better than the quarter mile trap speeds it gets.
Rs7 may trap higher but in a real world highway pull it's usually in the e63s favor so in higher gear with less tcu lockup the power is definitely there.

lol too funny on the look
and as far as brake boosting, its hit or miss as some members have their car go into limp mode trying it as ecu/ tcu intervenes pretty quickly on some when it sees tps at x% while sees crank rpm at 0.... if the tcu ever gets cracked could be an amazing launching car

There's no way to launch this car well in competition. You can pay attention to the light or your rpms but not both. I can cut .0x fairly well if I don't mind 1.9 60ft times. Or I can try to brake boost and catch the rpms between 2-2.4k rpm while the guy next to me leaves me at the light by .5 seconds. And if I'm too early on that split second of 400rpm sweet spot it bogs, too late and limp mode.
just saw this on another site... weistec finally posted some actually run results, albeit not 1/4 mile. they posted a 6.15 sec 60-130 mph which is not slow at all but still far behind what fastest M5's are doing (low 5's) for cheaper
however weistec is planning to do a W5 (includes their $8k forged internals) which would essentially be most likely w4 at higher boost+ forged internals.... should be a highway monster but doubt it will launch any harder than a tune only car

Low 6 second 60-130 equates to high 130s trap? I know the fastest F10 M5 trapped 140mph so I'm guessing that's the one with the low 5 second 60-130.

Both times were with a 1 foot roll-out, like how most US car magazine report acceleration times to simulate the timing lights at a drag strip. If I recall correctly, I think the E63 S was using race start.
Wasnt there 2 M157 motored cars with custom manifolds running GT35r's? I need to find out who built house. But supposedly they were beasts on the highway. Pulled on one of my friends 800awhp GTR. Wanted to run him with my GTR at the time (1418awhp).
there is a guy down here in miami that has w4 on his cls and saw a vid of him running pretty even to a e55 until end of 3rd and then pulled on him... I would of expected w4 to be much faster than e55 as they are about even up to 80 mph (e55 was ahead at least first 60ft )
