Hi

How fast is a SL55AMG when derestricted and best place to get this done/cost?

Cheers

DMS have the necessary equipment. It is said in excess of 200mph is attainable, tyres being the limiting factor.

My C55 seems to be unlimited and i would say weight of the cars is the bigest factor, the 155 limit is understandable given the weight, compared to my 911 its no fun stopping the thing.

When Mercedes derestrict the cars they go to 186mph.

If you check out the VMAX they are around that figure.

At Bruntingthorpe you just 1.6 miles of acceleration before the timing beams, not far enough to max out most high speed cars.
A standard SL55 given enough room would be mid 190's DMS 600bhp car just over the 200mph that's why at VMax you will see SL55's at late 170mph's
and the modified ones into the 180's. However wind conditions can vary
top speeds buy 6mph or more at these speeds.
Braking wise I have done many stops from 190mph+ with no problem at all.

Agree with what you are saying that there are many factors involved with top speed runs.

Braking wise although they can stop the car, it's more the feel and effort in relation to some other vehicles.

Cheers for all the info!

She rushes round to 165 on the speedo then hits the limiter like hitting a brick wall she just turns off. My MB guy says derestricted it will do 206mph on the autobahn but in terms of how much of a straight is required i dont know. Will give DMS a call!

"Because it`s a supercharged engine, it depends on atmospheric conditions , we have seen 335kph " ( 208 mph)

Verbatim from Evo magazine edition 040 February 2002. Original quote from AMG`s project manager for the SL55,

Bernd Baumann .

Added by John Barker : , though the tyres are only rated up to 186 , something to bear in mind if you are ever

tempted to remove the speed restrictor .

On the car they reached over 200mph with, I think it was later found out that it was geared slightly differently from memory.

I see, being taller geared ? Wouldn`t that also involve an engine with more power/torque , a mule then ?

Not sure of the exact details, but it was when MB gave a car to AMS for testing(there's a few articles if you search on Google)

This was at Nardo, normal gearing but a lot more power maybe 625- 650bhp.
They also managed a 0-186mph in 32.5secs which would need a good 640bhp
to achieve, [I know].
