G40 standard gear box:
Top gear gives 23.121 mph/1000rpm and top speed of 161.846 mph at 7000rpm (hence G40's 160mph clocks)
Engine speed in fifth:
30mph=1298 rpm
40mph=1730 rpm
50mph=2163 rpm
60mph=2595 rpm
70mph=3028 rpm
80mph=3460 rpm
90mph=3893 rpm
100mph=4325 rpm

top speed in 1st=39.876 mph, change in to 2nd at 4246 rpm dropping 2754 rpm.
top speed in 2nd=65.743 mph, change in to 3rd at 4905 rpm dropping 2095 rpm.
top speed in 3rd=93.882 mph, change in to 4th at 5231 rpm dropping 1769 rpm.
top speed in 4th=125.552 mph, change in to 5th at5430 rpm dropping 1570 rpm.
top speed in 5th=161.846 mph at 7000 rpm.

this is for the standard gearbox yeah?

mine tops out in 2nd gear at about 56mph!

Hi, yes the above is for the standard box, 56 sounds about right, what you have to take in to consideration is that the figures above are from a gear speed calculator, which does not see wind resistence/aroedynamic drag of the car, gradients of the road etc etc. We all know that in reality a G40 can not achive 161.846mph in 5th but on paper that's what it's geared to do but take in to consideration all other factors and you get a considerably lower figure.

Bare in mind the figures quoted there aren't for a stock rev limiter.
