The original puma's had a bigger connector where it meets the gearbox, so when a clutch was replaced you had to bend the pipe over to meet the box... They fixed this issue by re-shaping the pipe and fitting a new item so it would look more 'professional'
If there is such a 'valve' it's probably an item that's already part of the operation of the standard servo...
Reminds me of all the 'shot peened' nonsense...
There's no way that project could have funded a custom made gearbox with stronger gears in it... just ridiculous! all they did was select a ratio/final drive etc that was readily available that would suit the car.. and that's it!
The LSD was offered as an option in my opinion because it just wasn't good and reliable enough to throw into every car, plus again, it would have upped the cost too much... Interesting that they called it specifically a 'track day' option.... that's because they eat tyres on opposite sides and ruin the feel of the steering!.. :lol:
