Sonik engines in SKUSA Pro-Tour
Since the 2009 SuperNats, we continue to see very few Sonik engines in SKUSA regional competition.  In fact, during the first four races of the ProKart North and South series we have only had one entry with this engine.  Due to this continued lack of performance data, we have chosen to not permit the Sonik engine in the Pro-Tour. We encourage all SKUSA competitors to continue to use Sonik’s in our Regional programs to allow us to further evaluate its performance.
 
Leopard MY09 engines
We also have had almost the same situation with this engine in terms of participation.  Initial evaluation indicates a need to retain the option to adjust weights. We will continue to monitor the performance of the MY09 and reserve the option to add weight as needed. As is frequently the case with different engines, it appears to have a slight advantage at some tracks and have comparable performance at others.
