Open class is a drag racing race on the same drag track as the Rat karts.
It is open to about anything with a small lawn mower based engine. No Motorcycle engines at this time.
Racers will get a time trail for there open class "Kart". This time trail will be good for many races until there is a major change in your speed. If you make any upgrades to your kart you may request to run a new time trail. This is our way to save time. This way every single Open class racer does not need a time run each race. When dealing with most of these small engine's there pretty good at staying with in the same times week in week out.
How many ET groups and how wide of a time gap in these groups will altar and change as we get more racers involved.Our goal is to not have to many groups and for each group to be pretty tight competition.
The way things are looking groups would work like,
Group 1 ET times 21-23 Group 2 ET times 18-20 group 3 ET times 15-17 group 4 ETC,
The ideal will be to take the common ET's and make groups around those common times. This would mean when building a Kart you could push to reach near the top of a desired group.
If your kart is coming in at a ET of 20 you may be best to down tune or down grade and get into the 21 ET time. This is best done with gear changes. This should create some very even and competitive racing.
