VT V6 IRS Differential Strength

[offroadcommy]

Just wondering if anyone can tell me what the strength of the VT V6 differential is like.
i am currently racing a VH commodore in off road racing with a toyota quad cam V8 in it. the diff is a HQ V8 salisbury with a 4.44 ratio and i am still finding this to be too weak.
what i am wondering is if anyone has found the VT V6 dif to be any stronger or if anyone has had issues with the diff when up-specing their engines.
also is the V8 diff any different?

They can't be too bad, same diff in the 8's as the 6's.
