Just wondering if anyone would know or hazard a guess. What would be the acceleration figures for a CL65 with Kleemann tuning? 0-100kmh/0-200kmh and 1/4 mile elapsed time.

The power figure quoted by Kleemann - 739bhp and torque of 1300Nm is just out-of-this-world.
Plus, the Kleemann LSD system makes a lot of difference putting all that power to ground.

Sorry Gobiz I provide no answer for you but I would like to ask another question of my own. With your quoted Kleeman's 738hp and over 1300nm, wouldn't the transmission be fried? I mean DEEP FRIED?

Isn't that the orignal reason why AMG has eletronically limited the potential output of the 65's down to 1000nm? So how does Kleeman goes around this? Or do they just get all the power first and ignore the transmission woes that might happen in future?

I have raced a number of turbocharged cars. It is the easiest type of car to make go faster. Look at the list of parts needed to raise the power of a CL55 versus a CL600 or CL65. On a turbo, you turn up the wick and the power pours on.

But your concern with the transmission is correct. Turbos build a lot of heat... the impeller is now spinning at much faster speeds and their life span is shortened. The entire engine is operating at higher tempratures (and its high to begin with on this car). More heat builds in the trans... the differential is under more stress, especially if traction is increased by a change of tires. No matter what anyone says, you are stressing the car. These ECU mods are gaining the extra power through higher boost pressures... its not much else...

A lot of tuner cars break down in car magazine tests. This is a hand made, hand tuned, most reliable example of a car the tuner can hand over to a magazine. And out of 2-3 runs, one is a failure. Imagine if MB was selling a car with such reliability issues.

I am sure the Kleemann CL65 flies... but what are the #'s on a regular CL65? I am not sure I'd give up my warranty to go a little faster than crazy fast. You do know you lose the warranty? I asked.

Yeah, true. I found some numbers that Motor Trend got when they tested the CL65.
11.8 for the 1/4mile is quite amazing.

Still, it seems Kleemann is standing by their product.
739bhp and 1300Nm on the CL65 will be stupendous IMHO, of course reliability will be an issue.

Well this is the relationship between MB and AMG. MB engineers the car. They make something that is reliable day in and day out, smooth, servicable, can run on low octane gas, can be driven on unforgiving roads, something a guy in his 60's can drive without too many compromises.

Then AMG takes that car and hedges the bet. They take the 600/500 motor and bore it out for more displacement. Now you are talking thinner cylinder walls. They turn up the boost and go with more aggressive ignition... they squeeze more out of that same engine, but I guarantee you reliability is compromised some.

Now aftermarket tuners want to take what AMG has done, and squeeze yet more out of it. So if the car was able to make 100 horses all out ***** to the wall, MB lowers it to 80 and sells it. AMG takes it to 90 and sells it. Now tuners like Brabus or Kleemann take it to 99. Right to the absolute limits...

11.6 through the 1/4 mile, stock. What beats that? here is MT's quote:

• Fastest-accelerating auto-trans-equipped car we've tested
• Every luxury amenity you could ask for
• No ride/noise/harness penalty for all this punch

I say why mess with that.

If you want to make it more unique by some cosmetic upgrades, why not... but why mess with the motor/suspension. My personal opinion, but I'd keep my CL65 bone stock, and buy a Ferrari or something if you want to be over the top. If you like tinkering (which I do), do it on a less expensive less engineered car. For the money all the Kleeman upgrades will cost, you can buy a Lotus Elise and race the cra* out of it. Then get in your comfy reliable, quiet, smooth riding CL65 and drive home!

AMG2GO, all points true and great advice. At the moment, the E55 looks more like a reasonable car for my purposes but who knows, maybe in a few years when the CL65 has depreciated somewhat, passion may overrule logic, and I may hanker for a 739bhp 1300Nm v12

gobiz

Anyway, let's bench race the CL. If it does 11.8 down the 1/4mile at 120.9mph, with 3 things:
1. LSD
2. Drag radials
3. 127 extra BHP and 300 extra Nm torque (Kleemann tuning)
I'd bet it'll do low 11s and who knows, maybe touch the 10s with the right conditions and driving. Also less than 11.5secs to 200kmh.

Anyone else care to join my race?

Can not go wrong with Kleemann. Good buddy of mine just did the Kleemann K2 and LSD on his 2004 CL55 and he is pushing 600HP and 650 Torque. His car is approaching CL65 numbers and is running better then when it was stock. Having headers allows his car to run at lower temps then with the very restrictive OEM headers. Same gains with a stock E55.

let's calculate for the CL65 and SL65 with Kleemann tuning
4654lbs and 739bhp = 6.29 lbs per hp
4494lbs and 739bhp = 6.08 lbs per hp

Awesome performance!

AMG2GO

I think it is going to be even faster. I believe Chas Jr. on the forum here has ran 11.4 on a CL600 with Renntech upgrade. A CL65 will probably exceed this. If you do all the upgrades, LSD and drag radials on a CL65 you can probably get into 10's. Fast enough to beat crotch rockets. But I think you are bound for a breakdown with continous racing and with this setup. Just a matter of time...

FYI, you can probably go even faster with a very small shot of NOS, something like a 50 HP shot.... 50 HP is VERY mild, but the gains come because the NOS acts as a chemical intercooler for the heated turbocharged air.... it instantly cools and condenses it, giving you a lot more power.

Now THAT's what I'm talking about!!!!

A 739bhp, 1300Nm, 6.0V12, 50hp shot of Nitrous, luxurious high end Mercedes Benz CL65 doing 10's. That would be the ultimate.
Mind you, I'm purely bench racing. If I had the fortune to get a brand new CL65, I probably would be too scared to even change the tyres.

But then again, we'll see in another 4-5 years, who knows... there might be such a car cruising the streets of Kuala Lumpur

vraa

The nos is nice, but I'd get tired of swapping bottles out. I'd go for a thinner spray but bigger bottle?

AMG2GO

I'll bet the CL seats are a hundred pounds or more... each... a nice Momo racing seat is around 9 pounds. The spare tire, jack and tools are around 60 pounds. Switch the seats and take out the spare, and you may take 300 pounds out of the car. take the headlight sprayers, and mount them in front of the intercoolers. Fill the tank with water. Dous the intercoolers with water on acceleration. This is **** we used to do at the track... man I am glad those days are behind me...

i bet u the kleeman does nothing more of any point thatn the non kleeman car does.
600 hp, 700 hp, i t doesnt matter now, its all the same, its all abt the driver

James L.

He he he you'll see one in the streets of Sarawak soon! Muahah lol :v :v

James L.

LOL LOL LOL Ingenius!!! I might actually try it!

James L.

Aside from power braking to 3500rpm (which is think is the best launch rpm for CL55 above) and launching, what other commitment do you requires of a driver for CL/SL? Its auto box and everything is auto auto auto.

I can even sip a coke and eat some fries while drag racing after the launch!

Its not like you're driving some WRX or EVOs with manual transmission and spraying the intercoolers adjusting the tractions controls blah blah..

This is where the mighty merc comes in...

600 and 700hp difference? Sure there is, the latter generates more burnout smokes.. hehehehe

AMG2GO

Well you want to make sure ESP is off.... and you want to make sure all accessories are off.... especially the AC..... slightly lower rear tire pressures will help.... and just before launch you also want to make sure your ***** are strapped in tight....

Only 1 person touches on the safest and best substitute for horsepower....lose the weight. Losing the weight wont void your warranty. Im waiting for someone to tub one of these cars to lose about 500lbs.

T

James L.

500 lbs are not that hard. The two front seats alone should be able to shave away 150lbs. Who knows perhaps more.

But its rather sad don't you think so? CL has got one of the best seats out there.. i wouldn't dream of changing it to a racing seat! It just destory all the comfort with it...

Perhaps taking away the spare types, entinquishers, backseats? lol who knows.

I'm not planning to take away anything for mine though. 612hp is more then enough for me regardless of what weight the car is.. as long as it stay within 5000lbs

Feroz

James, I look forward to the pictures of your cl65amg , I have an S65 amg and I all i got to say is you won't be dissapointed with the cl version !

gobiz

EXACTLY, I think one of the coolest points of having a CL65 is being able to drive to say, a drag strip, in the utmost luxury and smoothness, then astonishing everyone there with it's amazing performance and driving back home again in utmost luxury and comfort. No need to remove any seats. :p
Anyway, the CL65 weighs 4654lbs.

James L.

My dealer says my car is still stuck in AMG factory waiting in line for modification. Car is delayed perhaps to mid of late april

Once I get my hands on it, I'll give all of my four benz a bikini photoshoot together! hehehe

James L.

Have you tried drinking coke and eating fries while drag racing? hehe I'll be :P
