Use of the MurfDogg OCTANE BOOSTER will provide the racer with more punch, better braking, cooler motor and ESC temps, more run time, better battery voltage deeper into the run..." ? If so then I want to build my own custom "octane booster" that will fit my car and needs.
Part of the fun of this hobby is experimenting with stuff! If you have the proper caps at hand, then it won't cost much to try them out. But PROVING that it will increase performance requires tightly controlled testing, with repeatable conditions and results. That simply won't happen on the track, as there are too many uncontrolled variables. While some guys enjoy doing controlled experiments in a laboratory with proper equipment, I don't think the average racer would. (It always seems like work to me!)
I think the largest improvement you'll see is in battery temperature, and that likely won't be much at full throttle. Showing a change in motor performance, if any, will take a very good dynamometer. That is a rarity.
If you intend to purchase caps to try the idea, simply buying a battery with lower ESR might give you more bang for your buck.

Some audio guys can go a bit crazy-- well past the realm of science, into superstitution and magic.
Given enough information, all of this stuff can be modeled and calculated, but I'm no wizard at math, so for me it would be easier to do the measurements. (Measurements are necessary in any case to verify that the equations and modeling are accurate enough.)
