I went to get a dyno on my stock CL65 today, rear-wheel DynoJet. The car cut power at ~25MPH with slip flashing. Even with ESP off, the light would still flash ~20MPH and power would retard. It's my understanding that the ESP disable only disables portions of the system. I didn't want to pull the ESP fuse. Is there a way to dyno these cars safely?

Did you have it in dyno mode? I took my sl65 in today and we ran it fine but couldnt find a lead so I have no clue on my lbft. We tried for like two hours and couldnt get a good rpm feed anywhere? Where did they plug into yours? We did get hp on my car but I want to know lbft as well.

You need to put the car in dyno mode. You can do a search, but I think it's the following:
1. Turn key on with engine off
2. press R button 3 times
3. Scroll thru the menu screen with the buttons on the steering wheel and you will see an option for dynamometer test.
4. Use the + and - to scroll to the dynamometer test mode.

What kind of numbers did it put up?

BiTurboAmg

552.3rwhp (447.2rwhp at 5500ft)

You're definitely not stock...... right?

Bone stock just picked the car up Friday. I wanted to get a baseline before Kleemann works on it. I just need to get that damn lead for rpms so we can lbft as well. I have read some postings from guys in the UK putting down about the same power. I am guessing the car has 660hp at the crank, one guy says 20% loss so that is 690hp which I think is to high?

blackbenzz

I thought they were at 604hp at the crank stock which is a little over 500whp. Thats my new goal with my 55k.

BiTurboAmg

Thats what I thought too. Trust me I was hoping for 480-520rwhp since that is what I have seen on most dynos for the 65's. I can only imagine the lbft? I am guessing may 650lbft? I need to find out where to hook up so I can test it out. I cant wait to see what it does after the tune??

Fikse

which is the rwhp the dyno measured?

BiTurboAmg

The 553.21 was the corrected value and for my elevation was 447.32

V12AMG

Dnyo mode...geez, didn't know about that. Is it in the manual, if so I didn't see? Regarding the RPM, we put tape on the upper pulley and used a strobe. Thanks to all for the help...back there tomorrow and I'll post my numbers.

You like a pro now!! Any way talked to Vadim he is going to see if he can pull some strings and get the car in this week. Sorry again.

BiTurboAmg

If you can take a pic of where they hook up so I can show my dyno tech. Thanks and dont forget to shift it up the gears until 4th then give it all she has.

V12AMG

As promised, the dynos for the '05 CL65, rear wheel on a DynoJet 224x. BiTurboAMG, will try to shoot a pic of the pulley tomorrow, but it's just the uppermost pulley, black and right/center/top of the motor. Just use reflective tape with an optical p/u. (PS is there a way to upload images to mbworld?)

Here ya go...

V12AMG,

Your RPM scale looks off, as the redline on the CL65's motor is below 6000 rpm. I suspect the pulley you chose is spinning about 10% faster than the crank. Great numbers, though. I'll be getting mine dyno'd soon, and will post results.

V12AMG

Here is one with the RPM scaled...you may be right. Click to enlarge. PS: Do you need a certain post count to upload to this site? It doesn't allow me to...
