Yeah wasnt that Edddd at the Ring?
Dunno what Ive had really Aaron, one problem is that on 18s and a Williams gearbox my speedo is out anyway, it always reads lower than the actual speed. Ive seen 137 on the clock, add quite a bit for the wheels etc, take off quite a bit for speedo error (common sense would suggest it reads high rather than low) and 135-140 sounds about right. Unfortunately I did that cos I was in a big hurry and didnt really have time to get a picture! Of course I was only in a hurry to get from one end of the airfield to the other.
I do seem to remember that mine when it was the standard box and 15s, used to do about the same kind of thing, 120 at 6 grand ie 20mph per 1000rpm in 5th. So taking it up to 7000 would net you a tasty 140, and with a chipped higher limit where you could take it to 7500 and not be in danger of bouncing off the limiter, youd be looking at the ton and a half.
Only problem is that in practice, the 16v really slows down at 125-130 in my experience and it takes forever to get any more speed once you get over 130, due to drag. Try a downhill run mate, see if you can do 150!
