So, I built a boost converter... (i.imgur.com)

You mean, the output voltage dropped BY 70V when adding the load, that sounds more inline with this sort of thing.
"Voltage drop" is basically just analysis speak for how much voltage is across one component as it operates, like you might talk about the voltage drop of a diode being about .7V, etc.
To make real high power and efficient boost converters you usually need multiple stages firing synchronously (kinda like cylinders in a car). With a buck converter, the load current can be constant and the input current will be pulsed, but with a boost converter both the input and output are pulsed, so using multiple stages (or phases I should say) makes even more sense to even out the current draw a bit.
