Those were actually a pretty good street pump. I ran one years ago on my Ford powered Sprite and it never overpowered the Holley carb. As I recall it was something like 4-5 psi. I don't know if they are still being made or not, but haven't seen one in years. Nice nostalgia piece. Worst that can happen is it craps out after a while and then you have to deal with putting something else in it's place.
