BGH Gearbox

This Morgan was original fitted with a 4 speed Ford gearbox. I converted to the Ford 5 speed standard T9 gearbox in 2001. It has been great with the fifth 0,82 ratio and 4.1:1 rear end though the first and second gear always has been much too short.
With the very high power to day, you hardly can stay a fraction of a second in the first gear, and the second was to high to start out with.
I decided to order the new 5 speed ‘Heavy Duty Synchro Gearbox’ design from BGH with the longest 1st and 2nd gears. It is rated to 280HP, but the Morgan is a light weight car so probably it can take more.
The BGH E8 is build on the Ford T9 box.

BGH E8 280HP/250lbft

The Rear-end is the: New 4.1:1 ratio from Spicer Axles Australia. Former Australian BTR Engineering, former Borg Warner 9 Bolt Rear-end. Rated to 295HP/229kW 435nm/320lbft in practice it should be capable of 500HP.

The below table shows the speed in 1-5th gear at 6500 RPM for the old and new configurations.
As you can see in the second gear
1) Old configuration with 185×65 R15 and Ford std T9: 91.5 km/h
2) New configuration with 215×60 R15 and BGH E8: 105.6 km/h

The new configuration made it very fast 0-62mph (0-100km/h) in 4 sec.
Better grip with the 215X60 rear tyres, though grip and gear shift is still a big challenge.
