Epic fail, filled the car with box oil last night, went for Millers Motosport 75/90, and the noise is still there.
We're 90% sure it's the gearbox, which is expected with the amount of power and abuse it's had. It doesn't select gears at the best of times any way under full load. Luckily I have the other Glanza sat there, only ever ran 0.6bar on a ct9 all it's life and feels smooth so should be ok.
Clearly wont have time to swap the gearbox's over before Japfest, especially as I need to split them and change the Quaife LSD over.
So the plan is, get to Castle Coombe, give it everything on track, if it goes bang, so be it, if not, it's the first job to do when were back
