Hi folks,

I have been looking at a few W212 2010 E63 M156 (RWD) but since seeing the the Eurocharge graphs it looks like their tunes have a much greater impact on the W204s and are identical to the W212s.

So should I just get a W204, Eurocharge it, get the economy and proper hp potential out of the motor and be done with it?

If so best to aim for a post 2011 W204 to stay away from known issues like headbolts?

If only the W204 had a 70 - 80 L tank... It would be a no brainer.

Thoughts on the sweet spot from this angle?

dchl21

its same engine.

Look at the 2011 204. They don't have the cooling issues of the newer models and they have most of the kinks ie head bolt issues...

Missionary

BigTickets, do you think I will run into cooling issues with a 12 here in NZ where the average summers day is 75 to 80 and a reallyhot day is 90?

That said we do have lots of fun tight, twisties and hilly bits.
Not really likely to track her though. Thoughts?

You will not run into any cooling issues. It gets up to 110 here in Kansas and my car stays perfectly cool, even with a lot of spirited driving.

I was ripping through the streets on Sat. night and saw my car go up to 259*F. What's the highest your car has heated up to?

INS1GNIA

Oh wow, that is pretty high. The most recent one I remember seeing was 230°F. Ill do some spirited driving on the way home today after work and write back on what I get, it's suppose to be 100° today.

I see 230 235 on daily bases without beating on that much

tasho3

Normal driving my runs around 220-230.

I did have my front temporary taking up half the lower grille as I new I would have to valet my car while is was out (And no I did not let the valet guy drive the car, paid him extra to live it upfront where I parked it myself) so that restricted the airflow causing the car to heat up.

Cooling isn't an issue with street use of the car. Lots of ppl are driving the car in 100F+ weather with no issues. It's really not a concern unless you plan on using the car on a road course. Oil temps have to get up to 278F before the ECU restricts power, and that's damn near impossible to do on the street.

Very interesting guys,

Do we know what MB did to the 12s to reduce cooling efficiency? Am I right in assuming there isn't an easy work around?

From a thermal shock perspective I would hope that these motors would flatline their coolant temps..

Either way it looks like I should be OK with a Euorcharged 2012 in NZ for the most part. Fair assessment?

BiturboSF

The highest I've ever seen mine was 260*F, sort of beating on it for about 14 miles, which was really only 15-20 minutes or so. Nothing crazy, just stayed anywhere from 3.5k-redline. This was in 55 degree weather as well


By the way OP, it is W204, not C204

INS1GNIA

I just beat on mine a bunch, highest I could get it up to was 234°. Just like yours, mine usually ranges between 220 and 230 though normally.

Missionary

Another question do the 2011's actually flatline on 230?

chris135b

This is the same kind of experience I have had with the 507. The highest I ever got the temp on the street was 263. The temperature rose from 230 - 263 in about 3 minutes. Mind you, I was beating on her pretty good on some nice mountain roads in upstate NY.


What is interesting: I can go really hard (allegedly ) in clean air (aka no cars in front of me) and the temp stays in the 220-235 range. The minute I get into traffic, for example into one of the tunnels in NYC/NJ after some spirited driving, the range climbs to 253-258 in about 2 minutes in traffic in the tunnel. This is repeatable in any temperature: 23F - 106F Ambient.


I'm thinking of getting the cooling package but I need some hotter temperatures in NYC to really do a *ahem* thorough test! We'll see.


To the OP, you will probably be fine with temperatures in NZ. Worse case scenario, get the upgraded cooling package if you start to go into Limp Mode with normal street driving.

Please correct me if y'all can find a link that says otherwise, but I don't recall EVER having ANYONE report problems with hi temps causing limp mode when on the street. And if it should happen, all you have to do is slow down a bit and limp mode will go away as soon as your oil temp drops.

The same thing works on a road course, but it kinda defeats the purpose of being at the track if you have to be coasting for cool-downs every other lap.

Bottom line, if you don't intend to track it aggressively, you will not have overheat problems with any model year of the C63.

Missionary

Curious as to why MB have come up with a cooling pack, are there that many folks tracking their cars? Anyone got a link / part number for the 2012 W204? Can see threads mentioning but not saying it is out yet.

zcct04

Kit is out and several members are running it. Do a search in this forum for "440".

Nice, the block off plate option looks like a good enough work around if I am not looking to track.
