dyno

was at the Service yesterday and sitting near my car was a 215 CL V12

in this holiday period, with few customers in and little to do they all like joking .. so the director of the service begun saying he would have bet that car to overcome mine .. I even don't know a lot about that car, .. so he said the mechanic to open the hood and plastics to show me her intercoolers .. then said she further had an Ecutune ..

I just installed a bigger medium sized pulley on my stock Cls55, ... feel her Strong ... hilarious would say .. but no ecu tune yet.

I didn't bet .. so they begun among themselves ..the chief electronic specialist is on my side ...

A V12TT with a tune is not to be taken lightly. I'm going to be brutally honest... It would probably beat you.

ItalianStallion

Not probably...definitely.

That car has TONS of torque.

blackbenzz

I was giving him the slight chance that the 600 would spin tires alot or blow up or something lol. I know how fast they are, I have Jason around here to constantly remind me

dyno

just looked at specs: if the 216 model is the same, they declare 517hp , 823N torque and 4.6sec 0-100kph. ....

I'll take account of BB advice .. must go ther enow, I'm already in delay

blackbenzz

You said it was tuned, it makes more power than that!

BlownV8

With ECU tune, the CL600 is making closer to 625 to 650 hp. The only chance you would have is if the intercooler pump failed or it blew a coil pack.

My E55 was slightly faster than my brother his S 600 TT (W220), raced several times.

From 100-200 km/h exactly the same, from 200km/h to 300 km/h the E 55 was faster. This was just the thing I didn’t expect when you look to the torque different. Both cars where stock (only without limiter).

So the CLS will be the same against the CL 600 TT.........

The torque advantage would be of greater benefit at lower speeds. The S600 probably makes only about 20hp-30hp more but with a 400lbs weight disadvantage compared to the E55. The CL600 weighs about 4,450lbs the S600 weighs a little over 4,600lbs. I think a stock CL600 would probably run even with a stock E55. A moddified CL600 (depending on the tune) should put some serious distance against either a stock E55 or CLS55.

Guys,

Having experience in both the V12 and 55k arenas - I can tell you, a HEALTHY Stage 1 E55 (pulley, cooling, tune) will almost make the same RWHP as an ECU'd V12TT (600, haven't dyno'd my 65 yet). A 55k w/ just pulley will not make as much power simply because of ECU Torque limitation that the tune must eliminate. I have the torque limitation documented on the dyno in the thread I made some time ago, and multiple tuners like VRP have provided a lot of info about it as well.

My SL600 RENNTech and Stage 1 E55 were within 1% of each other in RWHP, but the 600 made about 60rwtq more. I have the dynos if anyone is interested.

Bingo...

To OP.

I would stay away from the modded 600's since you have no ECU tune. Your car's ECU is actually trying to fight the higher boost with timing and fuel. You wanna good shot, snag a tune for that pulley and she'll really perk up.

Still would be a rough one though.

TMC M5

Wait a second...the chief electronic specialist is on your side in the betting??? My money is on your car....one ECU flash from the chief and that CL600 is in limp mode..

600 with ECU/TCU tune is faster if traction is available. With all traction aids on it is just too easy in the 600. I have owned both and the 600 does everything faster in the 1/4 mile with the above mods.

jangy

If the 600 is tuned it will take an E55 with just a pulley, easy.

Offtopic but what part of Italy are you from? I'm going to be moving to Firenze in two weeks for a semester to study and it'd be cool to meet up with some AMG guys as I'm going to be deprived of the beast for 3.5 months

dyno

I'm back ...exciting !

here is supper time but as anybody prepared anything yet, I'll try a writeup.

btw, as I showed here https://mbworld.org/forums/w211-amg/256455-test-braked-dyno.html my car's basedyno before pulley is this:
438WHP at about 5000rpm, Uncorrected, 3rd gear, 163Kmh; 10.4 Psi boost; IAT 142 F; Timing +11; AFR .905 volts.
28C/82.4 F ambient temp .. and a lot of humidity.

and 312.3KW *1.36= 425HP at 6000rpm;about 200KMH; 9.4 Psi boost; IAT= 155F; Timing +14; AFR .935 Volts (higher Volts value means more rich)

DIN correction that must be applied was shown in 2.1%, therefore values will be a bit higher..

I think after this "small" enought pulley 166 OD - 161 ID ( vs 151 ID Stock) I have now about 25-35whp more.

.. continued

dyno

must say that, when speaking with them first time I didn't think that car had all that declared power I have red after. besides, nobody knows how much hp that car has now: they told me the name and sure the tune was made by a very experienced Turbo modder. The tech at Service told me they understood it was modded because found some modded parameters ...
must also say that the car has a huge amount of miles on it.

I arrived there and she was half disassembled as was in because of some suspension failure.
inside it was without center panels, no shift knob ...

director said: if we want to try we must hurry up because tomorrow the owner (a friend of him) would have come and take the car away for holidays.

funny that whn I said .. OK , 5 mins watch time .. and panels, know , tec were in place. Never saw people work so quickly at a dealership

Director and Tech shaked again hands for their 100euros bet.

The Tech came with me while the other alone .. simply so
but , we can take it for weight compensation: so I had my 100kgs more (roughly 220+lbs I think)

He exited the Service ahead and we went to our future starting point. I think he immediately pushed hard on the gas .. just to show me what we were talking about. I was a bit surprised and .. me and the Tech looked at each other a bit worried

Ok, I m not a writer so better to be short. see below Start and Finish.
it was nothing 100-200 mph ( also because my car is still limited) but a simple 600meters (say 400mt useful)from standing still/stop.we both were in S, Esp on.


windscreen down, Tech said .. ready..GO !

i even don't remember if I had traction issues or not .. but seemed to me a good start .. except he complained with me later because I waited a bit.
I simply saw the other didn't start immediately so waited for him to move first. I wanted avoid a false start, but I think now having red your posts above, either the turbo was spooling or he was slipping. Indeed we are speaking of fractions of seconds.. in any case, my mistake.

First, say 80meters, we still were more or less on pair. maybe me a bit ahead .. but I felt him coming closer and closer .. for passing me
I was already thinking that, when I saw her .. like going backward! wow.. great!
I think it was because my car had already shifted to second (and lost corresponding time), while he was keeping revving high, still in first .. and when it was his turn to shift.. he seemed to go backward.

During those milliseconds I remembered what the Tech was telling me before: <<that car revs high a lot .. she will pull up further and further and in a long run, you couldn't resist her>>.
This sounds a bit different from what you posted above .. maybe her strong pull at high revvs is because of the tuning ?!?

so, after she shifted and the whole my second gear, I kept going ahead .. very slowly on indeed .. till a max of my full hood lenght.
time I shifted in third and .. again I was seeing her menacious coming closer and closer
but ... we had already passed 400mt and.. GAME was OVER

Addicted2Speed

Can't really agree with you, 600 with ecu makes about 515whp, while stage 1 55 (pulley/tune) makes about 450whp. There is going to be at least 50whp difference and an even greater torque different. Not to mention much broader power band in the 600. Maybe something was wrong with your Renntech SL600.. because there two different dyno's on dragtimes showing 520whp

JAYCL600

I applaud your efforts at telling the story, but I am completely lost

dyno

ciao,
I'm close enough .. 100-120km.
Bologna.

you should come with some american goodies for my car ..maybe those Apexy valves or..... I'll think about it

I'll drop you a pm

dyno

you mean it 's so badly written that you hardly can understand ?


I forgot to say before that at first I underrated that car because all what I knew about her was that she was not an AMG.

.. I learned something.

what I liked in that car is her FRIGO BAR option



...for those more performance oriented I would suggest use it for cooling our IC.
this is exactly what I was referring to in the other thread on this subject:
- wheareas Killerchiller (that is connected to the AC line) draws consequently power from the engine ... slightly less that same amount as it 's able to provide in engine's favour by cooling intake air temp. Secondly, it doesn't work during kick down .. that is when it is more needed.
- this is an electric device, very efficient. It draws a bit more from you electric generator .. it is like running an audio amplifier.

on the same topic I spoke with a tech there at the service and they told me that.. don' t remeber exactly, maybe the former E200 diesel version, had something like a fuel cooler installed close to the fuel tank inlet that worked somehow by mean of the ACline.

Vadim @ FD

Dyno, the way you write, you remind me of how my wife talks.

She is Sicilian.

The fridge in the back seats is COOOOOLLLLL!!!

jangy

haha!! Marco!! 600s are sleepers, bro. V12TT plus a tune is no joke.

That fridge is available for W211s that have the ski hole....




Marcus : What brand is your E55 stage 1?

Marcus Frost

Gents,

I do not believe my SL600 was running poorly because the car was raced quite a few times and always performed consistently for the power it was supposed to be making. It is possible that there was some TQ limitation but I do not own the car anymore so I cannot verify it. It will be interesting how my 65 stacks up.

I dyno'd my 600 on the same dyno I did my '03 55 and my '05 55 - CPT's Dyno Dynamics dyno. My 55 when dyno'd, had the LET ECU, VRP Pulley, and CPT Cooling kit. If you refer back to my original post, I emphasized the word HEALTHY in all caps, because E55s can vary 10% very easily even with the same mods. From what I have seen 410-420rwhp is typical on CPT's dyno for a Stage 1 car. My 600 made a hair over 440rwhp, and 55 made 436rwhp (stage 1).

Again, the 600 had a good 620rwtq while my 55 did 560rwtq.

I do find this somewhat curious given the claims for the 600s hp, but it's not outside the realm of possibility. A VR550 E55 and VR620 600 are about thirty-something RWHP away. If my car makes 20rwhp more than an average 55k, and maybe RENNTech doesn't make as much power as VRP... you have two cars in the same ballpark.

04E55 did 121mph with his RENNTech ECU'd S600, and some E55 guys have gone 118mph bone stock (including myself)... you don't think with Stage 1 (+30rwhp) a healthy 55 car can run with a ECU'd 600? I beg to differ...

Max.H

What does the stock 05 sl600 run in the 1/4? Has anyone ran one with a stock E55? I hope my friend is not looking in here, because he will know whats coming!
