that sounds unrealistically slow to me?
last weekend (at the same meeting that the F3's were running) Neale Muston managed to be doing 277Km/h in his 997 cup car (and he was nothing like flat though the chase), I find it hard to believe that a current Audi R8 GT3 would be slower than this.

I would have thought that a good GT car would be a lot quicker than 255km/h down Conrod. Hell, i did that in an XU-1 Torana!

I agree, I would suggest an un-restricted 458 would be closer to 280-290Km/h.
from what I know of F3 cars of that age, typically ~155Mph is the terminal velocity (~248Km/h)

F3 has greater downforce than GT3, which in turn has more than V8SC.
My thought was that the power/gearing/downforce/drag ballance of the Ferrari would have given it a far higher difference in speed trap readings than the 10kmh quoted.
Are there any sources of data available to demonstrate how much and why?

agreed, the figure given of 10Km/h I regard as tosh.
Hard to say without seeing the data, but I would be surprised if the F3 cars are not at terminal steed up the hill too (we were touching 240Km/h before turn 2 in the Lotus), and I am dam sure they are not having to brake anything like as hard as we do to make the turns.
