Considering running a RWYB class at a race and have a question.
How do you determine the rules when you have multiple karts and engines in one class???July 18, 2013 at 2:54 pm #3966
But isn’t the point of RWYB that, well, you run what you brung, and that there aren’t rules, besides safety tech?July 18, 2013 at 3:03 pm #3967
It depends on what you mean by RWYB. Traditionaly it done with the following requirements:
1) It has to be a kart.
2) No minimum weight.
3) Minimum age – 16, 18, or 21 – depending on what your insurance says.
4) A maximum engine displacement – 250, 350, 500, or 600. Again insurance dependant.
5) No restriction on body work except for overall length, width, height.
6) Standard safety requirments for brakes, safety wire, etc…
If you want to try to equalize the various typs of karts, good luck. The only one that is roughly equal is that a CIK Sprinter with a 250 single on it at 385 pounds is roughly equal to a 250 ICE kart at legal weight. After that all bets are off.
A class like that is usually just for fun which is good because you’ll never make it “fair”.July 18, 2013 at 7:59 pm #3993
Rules??? We don’t need no stinking rules!!! 🙂 Benn pretty much explained it. I really believe this is the growth class of the future, a sort of anti-spec class. You may or may not know but I helped write the original rules for the USKGP RWYB class. The intent is two-fold: A) help promote and give the opportunity to the mad scientist aspect of the sport that so many of us miss hence the ok of NO2, alky, blowers, turbos, big cc’s etc etc. and B) to make a class for karts that are obsolete for today’s classes (aka C-Open), or otherwise just don’t fit anywhere else. Some places are breaking the class into 2 groups, Big Motor and Small motor, but otherwise rules concentrate on safety. Super exotic stuff often doesn’t stay together very long. So it is quite possible to run well or even win in a basic 125 shifter or the like. Bring it on. Variety is the spice of life.July 19, 2013 at 12:18 pm #4080
I understand what RWYB means but was curuios about awards. Looks like that doesn’t make a difference. Thanks guysJuly 19, 2013 at 2:52 pm #4113
Awards for a RWYB class are kind of an “all or nothing” deal. Either you beat everybody or you guessed wrong. Certainly a reasonable trophy for the winner (date and track on it if you can) and then maybe a second and third if participation allows it.July 27, 2013 at 10:51 am #5104
Saying you’ll never make it “fair” is not totally true. Maybe with a “heads-up” format but not with a “bracket” style format. Dissimilar karts with different engine(s) packages with similar speeds can be combined without anything other than rules covering safety. Naturally you wouldn’t want a Briggs on the track at the same time as a 250 shifter. But you can have a race for (X) number of minutes, throw away your first lap time since it may be from a standing start, and whoever maintains the most consistent lap times for the duration of the race is the winner. Second most consistent gets second, and on down. That’d enable you to combine a great variety of singles, twins, shifters, etc. without worrying of weights or matching like categories. A simple concept that lacks scales, tech, and a ton of rules. Rules are for spec classes. RWYB is for those who remember karting before “cookie cutters” took over.

“RULES ARE FOR SPEC CLASSES” ?? Am I missing something here?? ALL classes have some sort of rules rather it’s just bore/stroke for engines.
Looking at something like 125cc and down. We want it to be something more then bragging rights, they are paying a entry fee. We are playing with fatest lap time including counting first lap (of each class) and then, split the starts. May not happen but just wanted to ask those who do promote this class on how they did it.July 29, 2013 at 3:50 pm #5227
If you have a variety of classes and speeds you could use the Pursuit format to make an interesting and competitive race. We used it for all our races for many years.
- Time the practice for the karts involved and then sort them by their fastest lap.
- Take the slowest karts lap time and calculate how many laps they could do in the time you have in your schedule. That is the number of laps in the race.
- Take the lap time of all the other karts and multiply it by the number of laps.
- The amount less than the slowest karts total race time is how long they must wait to start.
All karts start from the pit lane.
You have to decide if you want to worry about people “breaking out” by going too fast, we never did.
It was sometimes necessary to assign a time to a kart that had trouble in practice.
In theory, all karts will finish at the same time if everybody drives every lap like their best. In practice, we did have a fair amount of the field finish on the lead lap for our 20 minute races. It’s fun to watch a race that gets MORE exciting as it goes along instead of less.
