does it have pe PP?

CELLryuu

yes.

nice numbers. what shop did you have that done at?

derek

Autoscope Dallas mustang dyno.

CELLryuu

thats what i thought.

so now we have two c63 coupes in dallas

are you a regular customer there? Carson and Steve are great.

derek

Regular now! U a dfwauto forum member?

CELLryuu

no, ill go check it out though. are you going to the jaguar race event at lone star park this weekend? im assuming you got your c63 at park place (as i did). you will be invited to alot of amateur racing events when you by a car like that at park place.

derek

I was not even aware of it p m me we should compare notes

manuel009

I don't understand. Are 433 HP against 487 that are written?

C230Kompressed

Damn good numbers!! Are the 2012s rated to have more power than the 08-11 sedans?? I thought I saw dyno's by other members around 380whp stock., same dyno.

derek

the 481/443 is at the crank according to MB, the 433/410 is at the wheels (drivetrain loss). the numbers indicate about 10% loss, which is good.

derek

I don't think so, but I have the Performance Package thus the HP rating (not tq) is higher.

-=Hot|Ice=-

That's not bad at all!

C230Kompressed

Ahh I see, man well those are great numbers, can't wait to see what you acheive with headers, tune and some race gas!

bluejae

very nice car... saw it in person yesterday at autoscope...

Mikegpr03

nice numbers! Welcome to the 400+ club

derek

Great sig...gosh, this is my 6th 400 plus car, 3 of those over 500

That is thanks to the MCT transmisison =O)

CELLryuu

actually, its thanks to mb under-rating the power output for marketing purposes. its actually runnning around 510-520 horse power at the crank. the engine is almost identical to the black series engine. the black series engine has some other options on it like a crank case pressure decreaser (cant remember what the technical term is for it) but point being, mb wants to keep keep a class seperation between the c-class and its e-class.

there are many threads about this but basically the p31 package is equivalent to a tuned c63 or an e63 amg.

The accepted drivetrain loss for our automatic-equipped cars, measured at the wheels is 18%. Manual transmissions don't even allow for a 10% loss.

SonnyakaPig

The MCT transmission is the same automatic transmission as the 722.9 in the MY08'-11'. The only difference is the use of the wet start-up clutch in place of the torque converter. That change doesn't account for any difference in drivetrain loss, at least not one that we could measure.

CaliSun

I was thinking 15% loss but either way MB under states the numbers for the official values. The dyno at Thunder Hill racetrack measures the drivetrain loss so when I get the car up there I'll see what numbers it produces.

derek

I love thunderhill

CaliSun

I've not been yet, I've only done Laguna. My friends love T-hill though so it's only a matter of time.

derek

It's fast fun and lots of run off
