On a Car competing on rough stage events there's a good chance that an alloy bellhousing could crack due to fatigue where it bolts to the gearbox, I have seen quite a few like that. Having said that I have used the said bellhousings where there's been no support, only the std 6 bolts fixing it to the block and I have never had one crack.
