Of course an 1/8 mile track can make it. We have a track close to us, Lancaster Dragway, I think it's now Dunn Tire Raceway. Been 1/8 mile for decades. You won't get any closer to the race cars without stepping onto the track. Been operating for decades. I think "what's it take" is a difficult question. Kinda like the restaurant biz, probably one of the toughest businesses out there, many attempt it only to close in a short amount of time. A few become wealthy at it. I think there are so many variables that apply to each track, like location, demographic of local population, the monthly nut to keep th lights on, the pool of racers to draw from, etc. And a little bit of luck, weather-wise, especially where I live in the northeast. We have another local track, Empire Dragway, great 1/4 mile facility with a super long shut-down. But since I was a kid, I always wondered if that track was built under a permanent rain cloud. Having said all this, the obvious ingredient is promotion. Whether the owner does it or hires someone, to make real money, you need to promote shows of all types and sizes, and many tracks have one or two big events a year that often help insure profitability.
