200mph+ for less?

Extracting 200mph out of the 6.2 won't be easy without throwing big money at it. It will be lucky to achieve 540bhp with a remap. The 5.5 would probably be the better bet as there's far more modification options.
Personally, I'd go with Mercedes but it wouldn't be the AMG's, I'd go for the bi-turbo 600's. They can be had for peanuts and remapped they are 580bhp.
So that would be my wager, a W215 CL600 Bi-Turbo with DMS Remap. I'd be confident it would out run any E55 on a similar budget (roughly £10,500)
I had looked into the re-map on my 63 but it doesn't give huge gains like you say. The 5.5 will hit bigger figures at less cost and those figures would crack 200 I'm sure. Pulleys, re-map, exhaust and you'd be looking at what 600bhp or more? Personally, I'd go with Mercedes but it wouldn't be the AMG's, I'd go for the bi-turbo 600's.

6.0 bi-turbo is a good shout. There is a ropey looking S65 on Autotrader for just under £15k and that's 600bhp, re-map on that and limiter removal could see some monster power.

Setting aside the fact that 200mph on the Autobahn is still likely to attract the attention of the police, you'd have to be mental to want to try that is something "a bit leggy". At that speed I'd want everything to working perfectly.
Why would the police be interested?

Because "within the speed limit" is not the same as "safe" and dangerous driving is illegal.
I think they're pretty much mutually exclusive in this case - its unlikely you'd be trying to hit 200 anywhere that would be deemed "unsafe", you wouldn't be able to get anywhere near 200 in the machinery we're talking about without it being near perfect, its not like we're rocking up in a Veyron and punting it in a gap in traffic up to 200mph, we're theoretically running a 12k modded SL55 to just about hit the big number, on a very clear, very long, very straight, probably quite downhill (i) bit of deserted autobahn.Alex_225 said:

You'll get easily over 600bhp and 700lb/ft on a 5.5 with just a remap. With exhaust mods you'll see easily over 700bhp.kambites said:
According to this: http://www.evo.co.uk/jaguar/9740/jaguar-xfr-225mph
Jaguar got an XFR up to 225mph with the standard gearbox and diff, so it's clearly geared for it.

It sounds like a stuka.

German coppers have very precise rules about unsafe driving.On it's own, no it won't, unlimited means unlimited.
For example, tailgate at ordinary speeds like 120 mph and they will ticket you.
Or use poor lane discipline, like sitting in the fast lane at 150 mph and
ignore what the traffic around you is doing and they will ticket you.
But providing you are driving well, German coppers won't bat an eyelid at 200 mph.
Top end hardware like Porsches, Lambos and Ferraris do over 150 mph all the time.
Wasn't there a case a few years ago of a Maclaren F1 getting maxed out at 230 mph frequently
by some bloke on the A3 near Cologne ?

Yes, parts of the Autobahn are unrestricted. In reality though they are normally quite busy so if you actually managed to achieve 200mph there is a significant chance of some form of hazardous driving being involved (yes, I know that PH is inhabited by driving gods but the actual reality is otherwise). The police do keep an eye out for tailgating, although to be honest the police seemingly aren't too bothered about this until there is significant speed involved. You are however required by law to keep a minimum distance of half of your speed in meters to the next car, so at 200mph that would be a minimum of 322 meters. Just stop for a moment and consider the logistics of driving 200mph and maintaining a minimum of a third of a kilometer distance from the next car on a public road. I didn't say the police could necessarily do you for speeding at 200mph but anyone going at that speed is going to be identified as a potential danger and will be observed, and most likely pulled for tailgating. My experience of German police is that they aren't the most humorous.This is just my own observation and experience based on being a German (well technically someone with dual nationality as a Brit and German) living in Germany.

Surely it should have gone over 200 based on the car and the output ?
If an E60 M5 can manage 205 with 500 bhp, I know aerodynamics come into it but almost an extra 200 bhp should have cracked it ?
What is a Power Commander ?
I would have thought so to but the best I saw was 196mph I will add that in every case I ran out of road it never felt like it was out of power If an E60 M5 can manage 205 with 500 bhp, I know aerodynamics come into it but almost an extra 200 bhp should have cracked it ?

my M5 (with a full Eismann system & map) managed 183mph on the same road but it never felt as planted as the SL.Off the line the M5 would pull 3-4 car lengths & stay there until around 80mph then the SL would just overhaul the M5. I think gearing is a big part of this.
A Power Commander is the bike equivalent of a piggy back ECU

Cheers, so pretty much a remap then ?
Not quite you can adjust the power commander on the fly to get your fueling etc set for the track you're at etc where as most remaps are set.A decent Hayabusa with the right bits on will set you back anything from 3.5-5k

Or there's the ZZR 1400

I ran in a delimited M6 in the autobahn years ago. The car was new with new tires and we checked pressures carefully. At that speed I would worry about tires big time Had no boosters but had taken the car straight from the factory to Hartge in Beckingen. There are two limiters on the M6..one at 250KM/h and a second at 305 MK/h. Hartge removed both of them , my M5 (with a full Eismann system & map) managed 183mph on the same road but it never felt as planted as the SL.Off the line the M5 would pull 3-4 car lengths & stay there until around 80mph then the SL would just overhaul the M5.

We went for a Sunday morning at 4am on there autobahn near Weisskirchen, with good weather and light traffic. Not sure I would do it in a very old car though. VIdeo here: (two delimited E63s)

Quoted power 560bhp so say 520-530 ish 
A 458 will "only" do 202 with 560bhp so how the hell a 14 year old E55 AMG will do over 200 I don't know.

Phaeton W12 manages 201 with 444 bhp
Bentley Cont GT's will do 198, as will a 911 991 turbo, not much needed to take them over that.
Power is obviously a big factor, but so are aerodynamics and gearing, possibly depends on the weather and where you do it, maybe ZX10 was battling a bit of a headwind when he attempted it ?
With Aerodynamics, swoopy/lithe isnt always the best way to go fast, looking aerodynamic, and actually being so are two different things, potentially an estate may top out faster than the saloon, it is immensely complex, a tweak here and there can make a huge difference just diffusing a vortex that forms can add several mph on to the top speed, stuff designed to go fast, and be stable at speed may not be the best choice for high speed runs, daft as it sounds as it may produce downforce, when for top speed you want minimal drag. I dont profess to understand aerodynamics, I just realise how huge an area it is and how conflicting demands influence the resultant shape.
I think that the E55 is in with a shout.
