The only time I see Ingenieur making a post in this thread that doesn't pertain to the topic at hand is when he is responding to you guys...
Nice first one or two posts btw... Seems the only reason you GTR and 911 owners came in here was to harass someone. Take it else where.
Does Ingenieur get under peoples skin from time to time, sure, why because he questions statistics and opinions based on facts and science and most don't like it.
Lets be real fellas, the guy know his stuff. Just because it isn't always situated with popular belief doesn't make it incorrect.

and in your first post on this forum you said you were a neo-****?
no real difference between a neo and regular **** is there?
I'm not up to speed on *****, other than they were (are?) terrible people
btw: we are not 'talking', this is written communcation

I've decided to make it even easier for you to follow, since referring back to a quoted comment is too difficult. Here you go, Art.

Any chance this thread can be kept on topic...?

I am trying to understand what the video was supposed to have shown
and that the M3/4 is not under-rated and is as fast as it should be
now you want to talk about an under-rated car? new Audi S8
no car that heavy with that high of a driveline loss should be that fast

who is 'cliff' and 'art'?
again, are you saying I should understand crazy people and their ramblings? is thestig 'crazy'? is that what you are getting at?
do you feel we have a 'special' connection or something? mind melding via internet chat room? I'm not feeling it...
a guy like you just broke into sandra bullocks house

I noticed:
1 no one has commented on the calculated torque being identical to BMW's rating of 406 lb ft
2 that despite being slow to start they trapped only 1 mph different
doesn't that mean the C had more power/torque since it made up speed faster?
the speed change is acceleration
a = F/m
mass is higher in the AMG and F = torque x gearing / tire radius in this case
so if 'a' is greater and m is greater, F MUST be greater

they bought it instead of the gtr
many more M3's sold than gtr's?
so they are all wrong? you are smarter than them?
they bought the wrong car?
ok
the noodle bit sounds racist

has that been posted? let's give it a look
3 dynos
motortrend
sportauto
rototest
all 350-380 range
that is a new article but old dyno
that is in another thread 480 hp / 480 lb ft
but times are 12.1-12.2 119/117
on par with more than a few AMG C tests
if it weighs >400 lbs less and has more hp and torque, how can it be the same speed? it's just a question, not 'hating' or whatever the kids call it lol
PERFORMANCE (C/D EST):
Zero to 60 mph: 4.0-4.2 sec
Zero to 100 mph: 8.7-8.9 sec
Standing ¼-mile: 12.2-12.4 sec
Top speed: 155 mph

Quoted: EAS strapped an M3 to its dyno and recorded an absurd 424 horsepower and 426 lb-ft of torque—at the wheels. BMW claims that the M3 produces 425 horsepower and 406 lb-ft at the crank. Accounting for the typical 15 percent driveline losses from friction, etc., this means the 2015 M3 is really putting down something in the neighborhood of 480 horsepower and 480 lb-ft of torque at the crank.
15% loss
WHP = Crank - 0.15 x Crank = Crank x (1 - 0.15) = 424 HP/0.85 = 499 HP
so they didn't even account for the losses correctly! lol
Torque = 426/0.85 = 501 lb ft
even if you do it the wrong way:
1.15 x 425 = 489 HP
1.15 x 426 = 490 lb ft
do you believe the car has 500/500? or 490/490? or even 480/480?
how do you account for traps <120?
BMW losses on dynos that measure losses under steady conditions such as the certified rototest results usually measure 8-10% losses on modern BMW's

OK kids, are we all ready for a time out from the recess antics?
PM's have been sent and bans have been issued. Any further impolite taunts or bogus accounts will lead to the original accounts being banned at the same time as the bogus ones.
Why is it that this forum has always had the nickname of "the Sandbox"? Hmmm.

so now you have 3 accounts all set-up to personally attack someone you mistake me for
but if this 'art' didn't get along with you he must be all-right because you are a $&&## apparently
he must have skull eff'ed you pretty dang hard for you to be so obsessed with him years later
he really did a number on you, years ago and you still fantasize about him...sounds sick really
all in an internet chat room lol

now back on topic:
who actually thinks the M3/4 has 500 HP & 500 lb ft ???
<3600 lbs and runs 12.2/117 with that much power?
same speed as a PP C63 that makes wheel numbers of 330-350/320-330 and weighs >400 lbs more?
the M4 has 20% more power at the wheels and weighs 10% less, has more tire, DCT, and yet runs the same 1/4 mile...
does this make sense?
