I'm looking at getting one of these duel oil pressure and oil temp gauges. Has anyone used them before and are they any good? Do they use a single capilary and what what pressure do i need it to read up to? I was thinking about the 100 psi and 140*c version, would this be right for a hayabusa engine?

I don't have a dual gauge, but I do have one of their gauges (boost pressure). The numbers are nice, the needle isn't the best quality, but the whole thing works fine. I like them. Not sure they are IVA compliant (sharp edges).

Regarding ranges, my temp goes to 120degC (hasn't got there yet), and oil pressure goes to 100lb/inch^2 where it gets to quite often (but it isn't that end of the scale that matters).

Cheaper if you buy direct

Stack is also worth a look at as they do some good cheaper entry level stuff

Old MG's had these with proper fittings, no electric wizardry to go wrong and needing voltage regulators.
