200 MPH

[crisisjez]

There is also many other variables to consider such as gearing and intake temps.
Even on an Autobahn 200 is way more than most 200+ cars can achieve, let alone cars that have just been mapped.

I will be having a go at 200mph on the Autobahn this year.

Performance Box 200mph, not speedo 200mph (makes a big difference

How did you get on?

De restricted E60 M5 on a clear Autobahn in the early summer morning. Its quite an investment but you can always sell it when you are done.

I was thinking along these lines. Obviously most German performance cars are limited to 155 but mapped to remove the limited there's a few that can get near the 200mph mark.

I've seen a de-resticted CLS63 hit about 195mph and I'm sure there's other M/AMG/RS powered cars that could do something similar. In fact something like an E55 re-mapped would see a hefty power increase and limiter removed.

Bruntingthorpe, Elvington, Woodbridge, Santapod have seen cars well over 200mph

but there not 'driving experiences' where you pay a few hundred quid for a passenger ride

Having been to a number of Vmax events in the early days, not in a 200mph car mind you, I've had the pleasure of scooting down the runway in the passenget seat of a fellow PHer's car or three, including a 200 run and a memorable 190 run in a modified AMG SL65 with the roof down and the F1 GP live on the TV. That was just one of the modifications (TV staying on) we're also talking 700 bhp. The grip that AMG Merc had on the twisties back to base was equally impressive, really gut-wrenching. It's doubtful I'll get to repeat the experience while actually driving, even though a 200mph car has recently joined the pack.

I got 141mph (verified) out of an old 4.0-litre XJ Sport at Bruntingthorpe. It only set me back £500, so I'm happy at achieving 70.5% of the target speed

Do intend to head back and do 200mph at some point, though.

You could always just buy a crappy Audi S4, give it to MRC with a wad of cash and they'll fettle it to 785ps giving 202mph...

Have we had these yet:-

Suzuki Hayabusa: 248 mph

MTT Turbine Superbike Y2K: 227 mph

Dodge Tomahawk: 350 mph

Possible; but requires a gearing change, limiter removal and NOS to hit 200mph. Even then, you'd need a decent run up. Ignore the hyperbole, the Hayabusa is not a 200mph bike out of the box.

Spend a good couple of grand and you can probably hit 205mph.

Fine if you have a spare £100,000 kicking about...

A concept bike as far as I'm aware and if any were made, they would be very very limited numbers and stupidly expensive.

The later 218 CLS 63 with a remap would probably crack 200 if derestricted, dont they tune to well over 600 bhp ?

OP here. Interesting to see someone's resurrected my old thread...

Embarrassed to report that I still haven't achieved the double ton despite now owning a choice of metal (and cf) that, on paper at least, is capable of doing it.

Clearly I must try harder...

If you're thinking 2x wheels (I'm not!) then my brother-in-law's best mate's home made viper engined bike has proved it's capable...

M5 or Porsche 996 TT seems to be the way to do it. Both are also capable of actually sustaining those speeds which is the most interesting part.

Interesting how nobody's mentioned an Audi RS6. Surely Ian's 960bhp RS6 could do the job or is it too much of a lump?

Evo did a feature on this a while back, and their conclusion was that it was actually quite difficult to achieve 200mph

yeah, an audi tt bimoto cruised past 200, all the other contenders struggled

It did it with "only" 740hp and in only 36 seconds from standstill

https://www.youtube.com/watch?v=9vI4CG7RhHs

Still haven't gone back to try it with 900hp but if I did I'm not too sure if the time would be much different as the redline has been reduced (7000rpm down to 6500rpm) which throws all the gearing points out. Previously 206mph was the top of 5th gear (still accelerating hard) but now 5th should end at about 190mph meaning you drop into 6th, which is a much "slower" gear for acceleration, for the 190-206mph section so the overall 0-206mph time might not be that much faster but I'd hope the 0-190mph would be

If the car is not geared for it, it wont matter if you have 50000bhp, i achieved 202mph at Bruntingthorpe first runs were done on a 255/35-18 and it was valve bouncing on a data logged 199.9mph at about 7700rpm, i changed the tyres to 265/55-18 and instantly went 202mph. I called it a day then while i still had an engine to drive home with!
Theoretically someone calculated the my car could do 218mph with the right gearing, but id need a sixth or a massive diff, its an LS engined TVR Cerbera making 580ish btw.

Hi - how did you know it was valve bouncing?

ps - solid speeds :-)

Ive had it before, when we had roller rockers and the weight of the roller bearing on the tip induced it, it felt exactly the same, like hitting a rev limiter and i didnt have one set!
Since then I've upgraded to supposedly better set of springs and really carefully shimmed them, so may?? have a few more revs in it, should have another go really!

Thanks for the response. What a machine.

Another one for the Kawasaki 12r.

I think it was Visor down that did an article where Mike Grainger from GT Motorcycles gave over his tuned 12r that had done 150 runs over 200mph, from memory not much more than a Brian Capper blueprinted engine, a pipe and some dyno work. Several runs over target at Bruntingthorpe.
