SL500 top speed

[100%Bitch]

What would the SL500 be able to do if it was de-restricted?

Anybody got any ideas?

 

[Dave's E55 AMG]

Not fast enough

 

[Mr Teddy Bear]

Too fast for the road's around Norwich Helen!!! ops did I really mean that???

middle age crisis, why not look at the rev counter and take it up to the red line,and that is the max

NO, not really, I just hate having things that are standard.

A good reason, cant argue with that

 

[100%Bitch]

So come on then guys, what would it be able to do?

 

[Speedmaster]

I am curious Helen, any particular reason for wanting to know this?

Only the obvious one.

Only the obvious one.

As the 500 will only go to 6500rpm max at 24 miles per 1000 =156 mph roughly

Is that all?

Where are you taking your holidays then

Its more than what I said,its hard working out a theoretical speed. My SL does 70 mph at 2000 rpm so you can work out what 6500 rpm will do, but there are loses to take into account

I found this little snippet...

"DRIVELINE

5 speed automatic electronic overdrive lockup transmission

1st: 3.59:1 or 45 MPH max @ 6,000 RPM. (3,650 RPM at 45 MPH after upshift)
2nd: 2.19:1 or 74 MPH max @ 6,000 RPM. (3,850 RPM at 75 MPH after upshift)
3rd: 1.41:1 or 115 MPH max @ 6,000 RPM. (4,250 RPM at 115 MPH after upshift)
4th: 1.00:1, firmware limited to 155 MPH @ 5,650 RPM
5th: 0.83:1; firmware limited to 155 MPH @ 4,650 RPM

Reverse: 3.16:1 in normal mode, 1.95:1 in winter mode.

That's right: the SL500 has TWO reverse gears! Select the "W" winter mode for high-speed reverse driving. At redline you can hit 50 MPH in the usual reverse gear, or 84 MPH in the winter-mode reverse gear! I hope Mercedes' firmware stops you from doing this. Let me know if you try.

Changing a few lines of code in the engine management firmware ought to delay the upshift from fourth to fifth to 6,000 RPM at 165 MPH and hit 185 MPH at 5,600 RPM in fifth on level ground. Don't do this. I calculate if you found a long enough downhill with a strong tail wind you'd get to 198 MPH at 6,000 RPM in fifth!"
Fancy giving the reverse speed test a go Malcolm?

Thank you whitenemesis so this roughly bares out my last post of 70mph at 2k revs

Re the reverse bit do you mind if I pass on that

 

[whitenemesis]

Aww You could give it a go on the 303 on you way home?

 

[television]

OK I will do it on the bit near you where going home from the meet on feb 24th
with Hanz in the car, where that Wiltshire 303 camera clocked me for 101mph

 

[whitenemesis]

LOL

That would confuse them

 

[type49]

The early G & H reg non cat cars always seemed a bit quicker than even the later 113 engined ones. + having slightly narrower tyres with less wind/drag should give it a higher top speed if de restricted. What it would actually do though....................mmmmm 170MPH???
