Has anyone else actually taken their car to the strip, or are you all waxers?

Here's two of mine. What's odd is that the second one is tonight after getting a decent launch, but I'm pretty sure that the first was before the Renntech reprogramming. Note that the MPH, which is typically indicative of horsepower, has not improved over stock. That sort of concerns me, but it did dyno out at 630 or so. Maybe Mercedes reflashed it since without me knowing!

 

0.4second is a huge time for 1/4 mile but how can it be the same trap speed? Odd... very odd.

Your 2nd timeslip is Renntech CL600 right?

Have you added any LSD from Kleeman or other brands? They are suppose to help your 1/4 mile by 0.3seconds at least! The more if the hp is bigger.

Your car is more powerful then my CL65 lol. I am thinking of Kleeman ECU upgrade but it is so darn expensive. Kleeman quoted me Euro 6980!! What do you guys think? Crazy price.

 

Actually at the track on the good runs I had no wheelspin, so an LSD wouldn't have helped. It sure would on the street though.

 

i choose brabus!
they got a huge turbo upgrade coming up 700 over horse!!!

 

Davepl, I think thats because you're not powerlaunching the car eg. releasing at 2500rpm. Else I believe you'll get an even better time. Unless you're on full slicks which is a different scenario

Mashimaro obviously you have no idea what Kleeman is about? Do some research before you post. Kleeman ECU upgrade alone (Reflash of ECU only) will bring the 65 up to 730+hp! and 1300NM.

And you need a bigger brabus turbo to do that? Gee... I am beginning to wonder if you have the 65 considering your lack of knowledge for it.

 

Amen to that!

 

Impressive timeslips

 

sweet times

 

Guys the printed Kleemann info is incorrect. To get the 1300NM and 730 HP, Kleemann did use larger turbos. That upgrade was supposed to be offered, but never made it to production. There is no such Kleemann kit. Kleemann and Renntech are getting about the same power with the ECU upgrade. Brabus does have a kit in the works with larger turbos, mashimaro is correct about this. Whether that will ever come out, we don't know. Like Kleemann, they may shelf it.

To get that sort of power, the turbos do need to be upgraded. They are very small from the factory. However other issues then need to be addressed including the trans, and cooling issues. I will also make the point that although larger turbos can produce much more power at the top end, the low and mid is lost... and the power increase does not always translate into faster times unless the trans gearing and torque converter are designed to keep such an engine in its power band. In other words a whole host of things need to be changed and that's what factory engineers are best at.

With both the Kleemann and Renntech upgrades the turbos are pushed to their max. At the top end they are working so hard and spinning so fast that the air is superheated. The intercooler can no longer sufficiently cool this air, and so power drops off.... at redline the engine has lost a lot of its power. But there are big gains in the midrange and so the car will feel much more powerful and improve its times. I can guarantee that with either upgrade, a lot more gains will be seen at lower altitude and on colder days when the air is more dense.

No matter what either company says, the life expectancy of the turbos is definitely reduced. Larger turbos will actually be MORE reliable for the engine as less heat is produced and the turbine speed is reduced, yet the same amount of air is compressed. But unless the factory does this or Brabus managaes to re-engineer part of the car, 1/4 mile gains will probably be limited.

 

Compare your 60ft times, 1/8 ET's and 1/8 Trap speed. That is where you picked up all the 1/4 mile time. If you did pick up that much power, you should definitely see an increase in trap speed though. It's highly doubtful that Mercedes removed the programming unless they replaced the ME control unit.

 

Your time is lowered because of your great 60' on your second run. If you had HP & TQ from your first run you would see it in your trap speed.

When my car was stock, my trap was about 115/116, know with Kleemann it is 120/121 which is a huge increase for a 1/4 mile with a sedan that is over 4000 pounds.

 

Exactly where did you get that info mate? That can't be true.

I just called Denmark Kleeman to confirm their quotations to me of ECU upgrade for my 65 and the reconfirms with me NOTHING is changed. Just ship them the whole ECU unit and they will ship back in 8 days. Just plug it in and voila, claimed 730hp on flywheel! Why would they lie this kind of stuff to their customer? I doubt your source AMG2GO. No offense.

They told me this engine if UNRESTRICTED can originally made 700hp and 1200nm with EASE. Now an additional 30hp and 100nm above that certainly is not hard. With more fuel injects and higher air fuel ratio, it certainly is not hard. I really doubt and do not believe a larger turbo is needed. With a larger turbo you can hit 1000hp perhaps.

 

Also if you said there is NO SUCH KLEEMAN kit, I am about to send my ECU out! Just getting the shipper and addresses correct. How would Kleeman dare to accept my ECU if they can't perform anything on it? Makes no sense.

 

James my source of info was Kleemann USA. Technical manager. You tell me what is going on if you know because we are getting different info.

Here is the e-mail I received from him:

Hello David-

The numbers stated on the KLEEMANN website include the use of hybrid turbochargers. Due to difficult availability of those parts (Hybrid turbos, the exhaust manifold is an integral part of the turbo, etc.), that level of tuning has been discontinued. We will alert the webmaster regarding the changes to the site. We thank you for your keen eye, and the website will be corrected ASAP. Currently, we only offer ECU upgrades for the CL, SL and S65 cars.

Kind Regards,

Cory Umemoto
Technical Manager
KLEEMANN USA, Inc.

 

AMG2GO, wtf this is confusing!

That means 730hp is not attainable without turbo upgrade? Why did Denmark side not tell me this? Its not possible. I remember correctly they told me ECU upgrade alone gets me to 730hp. I will check this out and come back to you.

 

Thats right James, that is how I read that statement. I also believe it because I saw the dyno graphs, they were posted on another thread here. I don't know how they can pull 60 more HP than Renntech does. I mean its the same car and you can only do so much with it. I'd like to see all this verified with a dyno graph. On everything I have seen there is a boost in low/mid RPM power, but at the very top the power drops off. Turbos are maxed out at that point. You can see it in the graphs.

 

Here is a graph. Keep in mind different dynos exhibit different numbers and this was done on a hot day at hot altitude. But you can see what I am talking about. You can actually see the stock car make slightly more power at the end of the graph.... the reason to me is clear. Turbos are maxed out. They are no longer effecient, the air is superheated, the cooler running turbo with the factory ECU is still making a bit of power. Of course the modified car will be much faster as you can see the big gains in the midrange and low end.

 

AMG2GO and James: why dont you try contacting each others' sources and finding out which one is right? I am intrigued to know why there are conflicting reports about this.

I first thought it maybe because they may supply certain items to one country, and restrict distribution of those certain items in another.......a possibility?

 

anyone can take a movie of a ECU tuned CL600 for me? I'm going to buy a second car soon to keep it for at least 4-5 years, and cant make a decision, I had 05 E55 ( traded it in) and loved the torque, now i'm deciding between AMG'S Great V8 or TT V12 I would really apreciate if you could make a short movie of your car accelerating!!!! thanks.

 

The V8 AMG model is a better overall performance car, but the TTV12 is a more powerful motor. If you want straight line acceleration, $6000 will get you a lot of power in the V12TT. To get remotely close (and not there, just close), you will need $16K worth of parts and probably another $6-7K installation labor for the V8. Otherwise handling, braking, and looks is slightly better with the CL55. The V12 is smoother and quieter.

 

I have spent close to that on my Kleemann 2004 E55 which is putting up close to the same numbers the the stock 65's are. Last dynoed my car was close to 580HP and 640TQ. I am waiting on the throttle body which is from the V12TT and the car should be complete and gain about a extra 25 RWHP and 25RWTQ. For a fraction of the cost since I need the 4 doors I made my own E65.

The car is just a reliable and streetable as in stock but when you hammer it look out. Now that I have the LSD installed, will hope to get closer to mid 11's in the 1/4 next time at the track. These times are in par with the stock 65's.

You can not go wrong with either engine

 

If ONLY we have the same tuning specialist and facilities here.. sigh.. now my car will have to remain bone stock as no one dares to touch it. Not even change the pulleys.. shucks..

 

It may be a blessing in disguise believe me. I have yet to see any aftermarket anything add to a stock vehicle the caliber of yours without taking something away. Its *always* a give and take. I just lowered my CL 0.75"... you'd think there would be no loss with a mild mod like that. But there is. Every dam mod always has a drawback. Anyway its not like we are talking about some slow poke here with the CL65 we are talking about an 11 second car stock. I AM NOT FEELING BAD FOR YOU JAMES!! :p

So what did Kleemann say in your area? did you get to the bottom of this horsepower claim issue?
