In an "open" differential like yours and mine, only one wheel receives power
at a time. In a limited slip differential, power is sometimes applied to
both wheels through a system of clutches. There are many variations among
manufacturers and models. If you are lighting up your tires constantly,
maybe a limited slip differential will help your performance but other than
that, I can't see what it will do. It is a big help in wet and slippery
conditions though. Good luck.
