I'm running about 20psi at the moment, I'd like to turn it up a bit more, but I can't be arsed to open the pump up again right now. 
Up to about 24-25psi should be plenty safe, but obviously any increase in power will shorten the life of the engine components, so again, it all depends how far you want to take it. Any idea of a rough power figure you're aiming for?
I should say, there are a fair few running 30+psi, but most of them are on a bosch....I don't know how hard people have pushed a lucas.
