Guys, before MKB changed their website, they had an SL55, MKB tuned, which had 558HP, and 800Nm of torque. Now, they said that the car was capable of 0-300km/hr in 26 seconds, yes 26 seconds. That is Porsche CGT time. Now, I though, simple, change the gearing for better acceleration, resulting in a loss of top end speed. BUT, they also said the same car reached 325km/hr safely after warm-up. Now, a standard SL55 AMG will do 202mph (325Km/hr) with no limiter.

And since we all know the Nardo test results were a bit fishy, how can an SL55 with "only" 58 more Hp. and a 100Nm of more torque, do the 0-300km/hr sprint in 26 seconds, without changed gearing, since it can also do 325km/hr!!!

So I got thinking in my naive technical brain, (i'm just a layman sicne I have no real technical knowledge of cars) how can this be, either MKB are lying or they've done something ingenious. I then looked at the new tuning packages they offered for the 55K cars, and almost all of them have changed gearing, BUT their 800Nm comes not at 2600rpm, but at 4190RPM. SO, if you get their most powerful tuning package for the SL55, WITHOUT changing the gearing, could you do 0-300km/hr in 26 seconds??? :
Here is the MKB packages...

So, in essence if the theory is correct, then why doesn't AMG design engines where the torque comes in at higher revs, that way the car will be insanely fast in a straight line (what an AMG is good at). This way, the gearbox will be stopped from eating itself up, and you have a FAST car. Supercharged engines are reknowed for producing great low end torque, the stuff you need in a car weighing 2 Tons plus, but if you move that torque higher up, (which koenigsegg also does), then you have a quick car, so what i'm trying to ask is, can't AMG do this? And if they do decide to do this, what are the drawbacks?? If any, I mean I know its gonna be a quick car, but I don't want a full tank of fuel wasted, by driving like an old grandma, and find I have to refill after 200 miles or so.

Technical experts...fire away, and please excuse me if I am technically wrong, I'm here to learn...

 

If you buy a SL55AMG you have 100% the same warranty conditions as any ordinary MB. I guess this explains a lot...

 

Perhaps, I should have explained. What I meant was, can't AMG do this into their engines beforehand? Like when they make an entirely new engine?

What are you talking about??
The E55 for example produces 700nm standard from 2650 to 4500 rpm and the SL55 from 2750-4000rpm. The MKB appears to produce peak power at lower revs than standard AMG as well. (5800 as opposed to 6100rpm).

 

I wanna know how can MKB make an SL55 do 0-300km/hr in 26 seconds, by adding just 58 more hp and 100nm more torque, without changing the gearing?

If you are implying that the performance figures from MKB are wrong, I would have to agree. To get a 1950kg car to acelerate to 300kmh would require over 700hp. maybe they were a mistake and that is why they have been removed. At 560hp it should take 34 secs and 600hp would be 32 sec.

 

I agree, but how do you know it would take 34 and 32 seconds respectively?

And 34 seconds, is about teh same time as a Lamborghini Murcielago, and there is nothing worng with that...

 

I have a German spreadsheet/programme that calculates such things taking into account traction aerodynamic coefficient, power, gearing etc.

 

Whats it called? Where did you buy it, and would it be possible for me to have a copy? Not to difficult to operate I hope.

 

I got it from the AMG board.
You can download it from here

 

You da man!

Thanks bud!

 

I downloaded it too Thanks.

 

I used babelfish to translate the variables into English

 

how do u translate it to english
