Hi
Andy, ask anyone that has big motor in a bug and they always say 1st is a waste of time, thats why I went to a taller 1st & 2nd.
I was out on the motorway near my house today and I checked my speed v rpm (my gear ratios are in a post a few above this one) in 4th. 3,000 rpm gave me 100 kph and 4,000 gave me 130 kph. According to my tyre calculator with my gearing and 24.4 inch tyres (235/40x17) I should get 126 kph @ 3,000 rpm, but my rear tyres are almost worn out, so that may explain the difference. Im going to fit some 255/40x17s (25 inch) soon, this should lift my kph to 143 kph @ 4,000 rpm.
