Car Classing is based on engine size:
- Class 1/1R is for engines under 2.3 liters, except Honda S2000 and Lotus
Elise/Exige.
- Class 2/2R is for engines over 2.2 liters, but under 4.0 liters, plus Honda S2000.
- Class 3/3R is for engines over 3.9 liters, plus Lotus Elise/Exige.
- Class S2000 is only for Honda S2000 on street tires.
- Class X/XR is an open class for any engine displacement and induction.

Rotary engine multiplies displacement by 2.0. Usage of forced induction multiplies displacement by 1.5. (This is in addition to the rotary multiplier, if applicable.) Tires with a wear rating under 140 must use the R class.

Wow...this is cheap.

I'm in Jerrett, you need any help on set up ?

You know I'm always up for it.

 

Thanks! I'll know more closer to the event.

 

Can I design the course this time ?

I have plenty of time this week.

 

I have already designed it using some of the elements from the Pro Solo course. Otherwise, I would tell you to go for it.

You are welcome to design the April course at TMS.

 

Whoever's designing the course, can we go counterclockwise this time? I feel like almost all the courses are clockwise (is there a specific reason for this?).

 

It has been several weeks since I designed the course, so I had to go back and look at the direction. It is counter-clockwise. I think most courses at Mineral Wells are counter-clockwise, but I have never really paid much attention. The direction is usually dictated more by other requirements (site layout, start/finish placement, and so on) than any preference or directional thought.

 

Sorry, I wasn't thinking straight last night. I meant most have been counter-clockwise (finish line is left of the starting line) and would like to have a few clockwise courses (finish line is right of the starting line). No idea why I said it backwards last night.

I realize that site layout definitely plays a huge role, though, especially at smaller lots. Lol, the only reason why I even care is because of tire wear.


I want to design a course that is more like gymkhana.

 

Too late ! How do you think the Nascar drivers feel...always going counter clockwise.

I think I race the best going clockwise myself...so no wonder why I don't like NASCAR.

 

The course...

 

I finally found some time to try to explain why courses are usually CCW at Mineral Wells. In short, it is the safest placement of the start and finish.

It is easiest to start to the east and finish to the west. If you tried to have a north/south finish, then you must have a very long cable to the finish lights and you have finishing cars pointed towards timing, the cars just starting, or the cars staged for the start. Some sites require this, but we try to avoid it for safety, especially at the speeds that MW allows. With that said…

The paddock at MW has always been on the west side between the entry road and the fence. If we were to put the finish (pointed west) between the entry road and the fence, then the finishing cars will be pointed towards paddocked cars. There is an infamous video around of a Porsche driver missing the brake pedal at finish and plowing into paddocked cars. Yuck! So, I like to have the finish pointed close to the entry road (easy escape for cars that cannot brake) or north of it. That is why the start is typically south of the finish.

We could leave the finish in the preferred position and just move the start north of it, but that would mean cars driving between paddock and the start would have to cross in front of the cars coming off the course. People would have to walk through there, too. So it is not safe and it is a long walk from paddock/restrooms to timing.

Since it is generally safer for the start to be south of the finish, we usually end up with CCW courses. However, there is an occasional CW course.

 

That makes sense. Thanks for the explanation. Maybe I'll just run the course in reverse one of these days.

 

That would be fun a backwards AuotX !
