PH needs JamieP to take his Supra to Brunters and see what she'll do, it hits 200 in standing mile (IIRC) Brunters straight is 2 miles so say 1.3miles of pedal to floor coming from the bottom turn at say 60mph..... Could be interesting 215-220 is geared accordingly ?

You would need a dedicated dragster on a drag strip, given a Bugatti Veyron just tops 140mph on a drag strip, essentially you are looking at a pro stock car or a rail dragster of some sort.

Brunters would be the best place to do it in a modified street car, it can and has been done before.

If you have the money and the nous to do it then go for it smile

It cant be hard surely this 20 year old pile of ste has done it over a dozen times with a best of 210.2mph.
The vid is back in 2005.



Seriously you need a lot of Power or a good CD. Seen 640bhp achieve it at Brunters it was a Porsche. In my Cossie you need 700bhp because its shaped like a Taxi & other will require a lot more. Above 210 it gets hard only 8 cars ever achieved that in the UK despite all the its easy claims wink. 215 my aim this year will require 950+ a good day & plain old good luck. Saw Joel in his Viper do it back in 2005 & only 2 have gone faster than him. No lads these speeds are not easy.
Red Victor 1 of the 2 has answered on the thread ask him how much Power he has biggrin.

Brunters is 1.8miles has not been 2 miles since the car park was used. The fastest Supra todate has achieved 213.8 at Brunters would be interesting to see Jamie have a crack at that.

Sunday morning on the A9 from Leipzig to Berlin

No Lorries (Banned from Autobahns on Sundays unless they contain perishable goods), not a great amount of traffic and a nice long straight road. If I can get to 140MPH in a 187HP DC2 I'm certain its easy for the bigger V8's (Assuming they have long enough gearing) to top 200MPH.
200+ is all about Aero, for example, F40 has a twin turbo V8 and only just makes it.

most road cars don't have anything like a good enough Cd and small enough frontal area not to need HUGE power to crack 200.

As already said, 180 is not too difficult, the last 20 dam hard.

You can do it on a BMW S1000RR which isn't far from standard:

The guys from Performance Bikes magazine managed 202mph on one with an aftermarket exhaust, a remap and sprocket changes. As they say in the article, it was done in less than a mile from a standing start eek

Glad to see your still running with it smile

Do you still frequent PF still?.

What's your car if it isn't a dedicated drag racing machine?! (albeit a brilliant one with numberplates) biggrin

And Brunters is about 2 miles long whereas Santa Pod is only 3/4 of a mile long incl shut-down. But I don't need to tell you that, you know that already smile

Just read on the wiki:

wiki said:
top speed = 223mph, and no bodywork came off. This was done at Bruntingthorpe in Sept 2008. That speed attained in a slow 19 seconds due to excessive wheelspin and coming out of the throttle
rofl slow

But this is why 200mph is both interesting and quite difficult to achieve in the UK. The faster you go, the less time you have to go faster still as you rapidly run out of runway. After 19 seconds, how much runway did Redvictor actually have left before he had to hit the 'chutes?


EDIT: and that is the main reason why I think this guy's attempts are likely to be futile: http://www.pistonheads.com/gassing/topic.asp?h=0&a...

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

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

I didn't use the chutes. Brakes only. If i'd had of used the chutes i could have got up to 230mph as i slowed down way before the end....
As for dedicated drag machine, RV2 was a street car we turned into a race car.
RV3 however... and we'll be at Brunters again this year for a crack at over 230mph with it,and a passenger.biggrin

The force of the wind is proportional to V^2, power is speed x force = V^3.
So if you can get to 140mph with 187hp you will need 187 x 200^3/140^3 = 545hp with the same aerodynamics.
In theory, theory and practice are the same, in practice, they are different.

I'd take one practical 200 mph car and one driver who has actually been
there over 100 theoretical calculations any day of the week.

The theory is consistent with what MADRod has achieved in practice.
