I think you'll find that the current generation of Vittorias come with 145max on them. Older ones, that look like exactly the same tyre, used to have 160 max.
I think you'll find the issue will be twofold with max pressure. One factor is the quality of the lip/hook on the rim, and the second will be the quality of the bead on your tyre. If you look at the construction of modern aluminium rims, then they are a double wall design and I would say, very unlikely to spread under any normal (even high up to 160+psi) pressure. Also consider (especially with carbon rims) that what causes rims and tyres to fail is heat buildup. This isn't really a factor on track wheels.
I do notice a handling difference between running 120psi and 140psi on the front wheel. I used to, and now really don't understand why you'd want to run any higher than 145psi using clinchers on anything other than boards. BTW I tip the scales at 120kg and that 140psi is fine for me training on the boards with clinchers. If you do like even higher pressures, go and get a set of good quality tubs
