Speaking to a guy who says his calibra has done 160 Mph because he was tailgating somone he was able to slip stream them to get past wind barrier. Is it geared to do this??

Cheers

A cally T book figure is 151 mph (i think) and that runs the f28... 1 extra gear amongst its other advantages

As far as Im aware there was two gear sets for the F20, both giving different top speed figures.

My old Corsa did 135mph flat out in fifth on the limiter at 8,000rpm! Tiimed by Redline.

The gear box isn't the only factor - rev limit has a big part to play, if he can rev to 9k and has the power to stay there, he's laughing.

Was I right in thinking there are two different ratios in the F20 boxes?

Ive been told of some people doing 150+ with F20's! How come could only manage 135 on the 8,000rpm limiter?
