Merlin negative G cutout too quick?

I can keep an MG TA for negative G for about2 to 3 seconds without it cutting out. The lube system is much more sensitive than the carbs, as merely throwing it hard into a roundabout can get the oil thrown to one side of the sump, but while I've heard bearing knock on round abouts and good hump back bridges, it's never had metering problems.

Of course it's a completely spurious comparison, but nonetheless odd that a machine designed for 2 D is more robust in this matter than a machine designed for 3D.

..erm, you got me a bit confused mate, how can you exactly put a car into negative G load?
