You said it dynoed 450hp.

ProjectC55

Wow so the 2012 E550 coupe now comes Twin Turbo as well? Tuned that will be a modded C63 killer! He's not krazee Jon!

Jesus Lord! I knew nothing about the E550 Coupe having this motor! In the future I could imagine the type of motor they put in the Next C63!!!

Here it is below check it out!!! 402bhp Twin Turbo!! Tuned this car is gonna be a beast and MB's fastest Non AMG car!!!!

Yes, the 2012's have the M278 engine, and it is a hell of a machine, they have actually been dynoed much higher.

My car is being tuned by RennTech, it will output 530hp and 606ft lbs of torque....This in a 3700lb car

ProjectC55

3700lbs!!!!

Dude! I knew nothing about it in the Eclass! All the C63 guys are gonna sell or should!!!!!!!!!! BEAST!!!!!!!

Your car has the potential to give a tuned TTE63 a run for the money and should murder the new F10M5 hands down!

What they are doing to these German cars nowadays is totally insane!

No chance against a 5.5 TT on the E63,Cls63 mod for modhttp://www.youtube.com/watch?v=5UDGnf1k6uw&feature=player_detailpage.

Check this insane gain just from tune on the E63!

np888

It may keep up with an E63 but a tuned E63 would still win. As would the F10 M5 which puts out 600hp without a tune. Regardless, an ECU tune M278 will destroy pretty much everything else in the Mercedes range.

That Z06 could have been shifted into gears much faster.

127mph trap on a Z06 means the car has bolt-ons and a tune or spraying.

OP what you run in 1/4 ?

ghiaguy

at that time, it would have been low 13s

TopGun32

don't usually post in the kill section...

but F10 550i... trap about 108/109 stock..

there are tunes available.. but very common. Even the piggy back tune from JB tuning is only good for a decent bump ..but nothing like the 4.7TT or 5.5TT engines from MB and AMG.

If you get the jump.. your C55 traps just about the same.. he will need more space to real you in.

ghiaguy

you speak the truth.
nice digs btw!

JB stage 1 550xi 12.363 @ 112.66 that's a $375 tune.

I have JB stage 1 on my 750 and had an accounter with a MB S63 once and it wasn't pretty for him as he really thought he had it in the bag . The 750 with stage 1 is putting down almost 420 rwhp & over 480 TQ AT THE WHEELS, stage 2 on the works and I'm going to love those new numbers

m4xm1l10n

I can easily take the OP's world on beating a Dinan 550i, You know as well as I do of lots of Dinan Software Actually being installed incorrectly In The Vehicles and yet most owners still believe they're faster until they get smoked I can tell the OP one thing, My stock 550i is a wolf in sheep's clothing

blackieclk550

So conclusion is he ran a stock 550i and not even a slightly tuned one

m4xm1l10n

Probably, OP modded ? I'd say Stock for stock 550i gets the edge ?

Funny reading all this ridiculous HP figures being posted about the BMW 550I , cuz I sure raced one about two weeks ago in my CLS 63 and couldn't help but laugh cuz I pulled on him twice by at least two car lengths, and am bone stock, oh wait I plasti dipped my rims black maybe that gave me couple more horses LOL

blackieclk550

exactly how it should be stock for stock the CLS63 wins being a more powerful car, now the 2014 550i has a bump in HP and should be neck and neck with your 2008 CLS63.

And put a few bucks into the (especially 2014) 550i tune and it's bye bye C219 CLS63 or even new C218 CLS63. People here are underestimating what a tuned 550i is capable of, and I'm not even talking about the 2014's with the N63tu motors with 450 HP that have raised the power bar against the direct M-B competitors.

Rafiki

What are you a BMW salesman , a tuned 550 really, whatever your smoking I would like some of it, who says am gonna stay stock for long or perhaps most people who buy NA63s , and then you said even the new 218 CLS 63 , so if a tuned 550i is supposed to blow AMGs out of the water I guess we have no chances against F10 M5s huh, please , the ginger bread man can be driving the 218 CLS 63 and still blow 550s out of the water , think again, if 550i was that potent , why buy an M5 then , I guess BMW must be retarded huh

K-A

Simmer down Napoleon.

A tuned 550i can indeed throw up comparable to better straight line times than an M5 (depending on the tune). It's a common discussion on BMW boards and possibly one reason as to why the F10 M5 isn't as enticing a choice over its "regular" F10 brothers as previous M5's were to their N/A siblings. The M5 is faster than a new CLS63 from what I understand and certainly faster than a C219 CLS63, so there's your answer.

Tuned 550i's are throwing up well over 500 HP with leagues more torque than your N/A 6.2L. The N63tu motor with 450HP stock is practically almost there on its own, with much more torque. Simple facts and logic. Both N63/N63tu motors have been shown to be underrated as well.

Rafiki

Sorry Sir i quite disagree, what tune will bump the HP on the 550I from 445 to 560 ????? , unless your talking about spendig some good $$$ you can beat an M5, or maybe if it gets up to 500hp it will beat a stock W219 but not a W218 sorry, i will just have to see it to believe it , we all know AMG always won the HP war , or whats next the 2013 E550 TT tuned will beat a E63 5.5TT ???

K-A

I'm not positive about the CLS63 VS tuned 550i indeed, but I'd imagine squeezing out another 100+ HP from a car with a V8, two turbos and an underrated 450 crank HP to start shouldn't be that difficult. I'm sure more knowledgable people with firsthand experience know the answer to that.

I'm not sue if AMG is still putting out more HP? Maybe recently with their Performance Package or whatever they call it, but I'm positive that the M5 had more HP than either the E or CLS63 when it came out (and still does over the "base" 63's).

EDIT: Just verified. The normal AMG CLS63 has "only" 518 HP which is far off from the M5, and even the performance package version has 550 HP which is still a little shy. Honestly I would imagine any decent tune on a 550i, especially the new 445 HP one will blow right past 518 crank HP (i.e the current "base" CLS63).
