Sorry, the speeds are based on a 5 speed 620 gearbox - and were just for fun coz TP asked me for them
The predicted speed does not allow for wind resistance etc. so I guesstimated on a 10% reduction (based on book speed of 115mph on stock gearing) which is shown as the corrected speed.
...but the speed side of it is all rubbish, coz you'd never pull 15/36 or whatever it is... at least not to 9,500 revs in top.
Hope that clears that up
