Gearbox modification - BGH Geartech Ltd

I have sent my gearbox to BGH Geartech Ltd for modification to match the gear raitios to the engine and differential ratio to give me a linear performance across the range.

Based on my 170bhp Zetec and Diff Ratio of 3.92 I have opted for the following.

Fast Road - E3 – 2.0 Sporting Close – Heavy Duty
Gear - Ratio - MPH
1st - 2.92 - 41 mph
2nd - 1.86 - 65 mph
3rd - 1.295 - 93 mph
4th - 1.00 - 121 mph
5th - 0.85 - 142 mph
