That's interesting. In my 3 litre at Bedford, I was pulling 145mph on the straight, which is about 1km long, and still going strong...

joust said: The 161 was with about 10mph of tail wind - I got 147 the last time I tried there with no wind.

Autocar's review of the gto3 seemed to think 170 and it was still pulling? Don't know which runway though (or more importantly how long)

[joust]

It was still going at the 161, just that the additional mph's were coming rather slowly - sort of like counting normally up in ones - trouble is that at 140+ one second is a lot of meters!

It was at around 140 on the clock by the end of the uphill section (the track goes half up then half down).

Joust/Nildram,

Any of these reported speeds clocked using GPS? If so, how accurate is the speedo?

[joust]

Yep - mine where all clocked with the Road Angel GPS and the light beam timing at Bruntingthorpe.

GPS was about 1mph out on the light beam, and speedo was about 5% too high.
