I have participated and hosted several proxy HO drag races organized by NTRA (National Thunder Rod Association). NTRA has a wide range of classes, ranging from T-jet Stockers and to inline Pro Mods. Track voltage varies according to the class that is being run -- for example, 13.8 volts for Stockers, 18.0 volts for Gassers, 22 volts for Pro Stock, etc. (As noted above in previous replies, check out rules, classes, and past events on the nitroslots.com website.)
This helps to differentiate between the classes, with quicker e.t.s and faster speeds for the more extensively modified races, just as in "real racing." Just my opinion, but I prefer racing at lower voltage because you can actually see the races unfold -- one driver gets a holeshot, the other gains ground at mid-track, and then they go side-by-side across the finish line. With the higher voltages and faster cars, it's all about reaction time, and the cars are just a blur (at least to my old eyes). It's a matter of taste. But I would suggest a variable power supply so you can decide what works for your track, your cars, and your events.
Hope this helps,
