Open Track Session Report: August 20, 2022

Thanks to all who came out for a few hours of track time on SR3 Saturday, really appreciate the interest and support!

The goal was to give Sportsman drivers some tips and tricks on driving technic and style. Unfortunately, only one Sportsman drive showed up (Kevin Webster) and he doesn’t really need any help.

Expert driver and 2021 Rookie of the Year, Brad Sandahl showed up with his daughter, Carrie, and did a bunch of laps. Brad certainly doesn’t need much help either but he tested various controller settings and by the end of the day had the fastest lap.

Julian Schwartz, another local junior driver, made an appearance and got to cut a bunch of laps with an OS3 Pro controller, which he seemed to adapt to well, and hopefully, gained some valuable experience for the next Kid’s Race at Stewart Raceway.

Kevin and I tested his various HOPRA-legal SUPER STOCK cars. The purpose of the testing was to determine if the HOPRA SUPER STOCK rules should be adopted. While these cars are very smooth and fast, they really weren’t all that much faster than an L4 V-SPEC Viper (HOPRA SPEC RACER) we currently run. Different, yes, but not really worth the extra expense of forcing a switch to ceramic motor and traction magnets. The HOPRA Super Stock class rules also allow dual-compound tires, which further increases cost and complexity.

The goal of introducing this new class to our racing program was to provide more advanced drivers and builders with a bit more flexibility in tuning their cars. The general consensus was that having to swap magnets and purchase dual compound tires was a bit much from a budget and performance gain perspective.  So, we decided to introduce the Super Stock class into the program but without the ceramic magnet and dual-compound rear tire specs–for now.

So what’s different?

Well, without the ceramic magnets and the dual compound rear tires, not much. But, you can run different gearing than just a 7/23 pinion/crown. Higher gearing, for example, can make the car not only easier to drive on twisty technical courses but also faster on tracks with longer straights. The idea is to allow the more advanced racer more tuning flexibility.

What does this mean to you? This class presents a bit more flexibility in tuning. Meaning, that you can purchase a few different rear axle assemblies with different gearing for different track layouts or conditions. Just swap axle assemblies to change the handling and speed characteristics of a SUPER STOCK class car.

Do I need to buy another car?

No, the Super Stock class is essentially a SPEC RACER chassis. The only difference is that you can run any gearing available in the SUPER STOCK class, the HOPRA SPEC RACER class is restricted to 7/23 gearing.

Will the SUPER STOCK class be run at all Stewart Raceway events?

No, at the moment only a few drivers are interested in this class.  If interest grows, it could be a popular class but only time will tell. Buy a couple of different rear axle assemblies and see if going to higher or lower gearing helps your lap times. If you determine that you’re faster with the gearing flexibility, then lobby in support of this class.

Keep in mind, that both classes allow adjustable armature brush tension on a brush-barrel type chassis, which is also a very useful tuning option. If you’re running that type of chassis, try them both and see what happens.

The SUPER STOCK class is intended to provide a bit more flexibility and a more sophisticated level of tuning for those interested in going faster and finding that winning setup on race days.

Okay, shut up and drive!
