Capped Entries
To provide maximum track time for every participant, we have capped entries at 80 SuperPros, 80 TaG Seniors and 40 competitors each for the other classes. The format of limiting entries and classes provides 5 days of virtually non-stop racing action. To quote Steve McQueen, “Racing is life. Anything that happens before or after is just waiting”.  To ensure your spot in this year’s event, enter early or you may miss out.
Race Format
All classes will receive three individual heat races, plus a main event. SuperPro will have a 30 lap main event, whereas other classes will have a 25 lap main event. The grid order for the main event will be based on points earned in the heat races. Tag Senior and SuperPro will run elimination flights.  Click here for details.

S3/S4/S5 Spec Honda Rules
Spec Honda drivers are encouraged to review SKUSA 2006-07 Rule Book, section 20.3.2.6. The new rules have been tailored so that engine packages conforming to nearly every Spec Honda rule set can participate in the SuperNationals with a minimum of effort and expense.
Rotax Senior and Masters Classes: Rotax Senior and Masters classes will be run strictly under RMC rules and regulations and all off-track technical inspections, rulings, etc. for these classes will be the jurisdiction of Champcar Rotax Kart Challenge personnel.Â

Spec Fuel and Oil
For Rotax Senior and Masters classes, the spec fuel/oil is VP MS93 and Motul 800 Factory Line 2. For all other classes, VP MS98 (ICC, TaG, Spec Honda) or VP C12 (built motos) is the spec fuel and Motul Kart Grand Prix 2T is the spec oil. Mixing ratio is open spec. Event entry includes 4 gallons of spec fuel and 1 liter of spec oil. Motul representatives have told us that Kart Grand Prix 2T can be run from 16:1 to 32:1 depending on application and driver preference. The richer ratios are generally reserved for high rpm, cast iron cylinder applications (example Leopards) and the leaner ratios for Nikasil cylinder applications (example Rotaxes). ICC’s and Moto’s would fall somewhere in between the two extremes.
*SKUSA reserves the right to revise event parameters without prior notice. Furthermore, the Race Director reserves the right to modify the event format, it’s length or any particular segment thereof in the interest of safety. Additionally, the Race Director reserves the right to issue a green, white or checker flag which will declare and record a conclusion of that particular segment regardless of length or time.
