Weir-Perfomance axle question

[cle]

Hello again.
Maybe somebody can help me out. I laready took a look at the tech section, but haven´t found much. I use a standard 6.7 pinion gear with weir 28mmm axles, 2way LSD, and a solid pinion spacer. Weir says, it is good for 350hp but no info about a torque restriction.
So maybe some has got experience with these products. As fas as I know, the standard pinion gear is the weak point, not the uprated axles. My plan was, to make about 400nm torque and 360 to 380 Hp, but it depends how much the rear axle can handle.

Thanks in forward,

Clemens
