Is my buggy slow

Thermals generally happen when heat is built up over time. If the current bursts are too high, it can draw enough to instantly turn FETs into fuses; the ESC just doesn't have time to catch that quick of a rise in temps.

Yeah, a buggy on 6s geared to 70-80 may be ok, but I know you are going to be pushing the ESC hard. Not to mention the brake spikes at that speed/voltage!

How comes that guy (Over_revO) got his e-revo which is a pretty darn heavy monster truck, to 91mph using the MMM on 6s?

I thought cogging was only really a problem for rock crawlers, where they spend most of their time at low rpm. For speed runs, the amount of time spent at low rpm is minimal so would cogging really have an effect?

Also, what are brake spikes?
