No forced induction, no nitrous.
Quite a lot of the time, when we bring you videos of insanely fast cars, they've got something extra attached to the engine. Be they superchargers, turbochargers or nitrous, the really low quarter mile times seem to require these things. But here is a Mustang which uses none of that and still manages to get into the 10s. It's using the 5.0-liter Coyote V8 that it came with, but it's safe to assume that a bit of work has been done to it, just not any forced induction.
It's just possible that you'll even find the sound which the car makes to be even more impressive than its quarter mile times. It really does sound that good.
