I defined / started 8 second NASTruck at The Grove years ago; it became popular for a few reasons:

The class was defined in such a way as to minimize the need for the best motor / battery / parts / tires of the day. The breakout concept neutralized all of that on the oval, but that solution is not really right for other forms of RC.

I got a few people (~5) who committed to run it for a month or so, and I was a constant cheerleader for the class. I created a document linked to the forum that gave a full accounting of the few rules we had, why it would work, and published my own truck's setup. On race weekend I would put my tweak board at the aisle end of the pit and let / helped anyone with their setup. In short, I was as open and welcoming in a type of racing (RC Oval) that is known to usually be the opposite. Everyone else became just as open and welcoming and a new culture around oval racing really sustained it.  At it's peak we had ~18 people showing up for weekend racing and larger turnouts for the 'Special' races. Other racers then decided we needed a faster class, so they started 7 second NASCAR, which I think was a mistake. Sadly, I've moved away and can no longer hang out at The Grove. I understand the track itself is in need of a lot of maintenance.

If I were designing a faster than 8 second oval class what I would do would be to spec the tires and battery. Back in the 80s in Mod classes you always geared your car to have the battery 'dump' at 4 minutes.  Why not bring that back as the limiting factor? Why not spec out what we would consider to be very small batteries (by today's standards) to limit the dollars race? A bit of experimenting would be required, but lets say that a 2S 1200mAH battery can drive a 10th scale car around the oval at a 6 second lap pace for 8 minutes. Due to the way physics works you are pretty much taking the brushless motor out of it (the gauss strength of the arm might be the only issue). Everyone is used to spec tires, so in oval that wouldn't be an issue.

But can this strategy be used in other forms of racing? Admittedly battery durability is a key factor. The spikes that off road mod creates might kill a smaller lithium battery with catastrophic consequences. In the early days of ESC's we used to wire in a fuse on the battery lead, running a small battery might require the fuse to be brought back. MaxAmps has a 2S 1350 at 150C. From back in the day that would be good for a 4 or 5 minute 10th mod buggy class, but battery durability and the desire for longer racing heats might not make this ideal. Maybe that battery would be a good 10 minute "Stock" class. What about 1850 and an 8 minute mod race? Or maybe a 1500 can be found somewhere... (Support your LHS, I only used MaxAmps as a reference.)

The point that I am trying to make is that there may be a technical solution found in the battery. LiPo batteries are by their nature physically regulated and pretty equal, have a long life span, and have no memory. They do not mind being run back to back, and spec-ing out a small battery actually makes racing cheaper. A 7.2V 1850mAH battery is carrying 13.32 Joules of energy, and it would be the job of the racer to use that energy as efficiently as possible to get their vehicle around the track. Someone has to do the experimenting though; someone would have to be willing to buy a couple of smaller batteries and spend a few days determining which ones give the desired speed and duration for racing. This is what I did to start NASTruck; the 8 second pace was completely arbitrary, just my opinion with some input of other people who happened by when I was on the driver's stand experimenting.

I miss the hobby / sport, I miss all the friends I made doing it, and I miss The Grove. I hope you guys still living in the area appreciate how vibrant the RC scene is throughout the Carolinas.
