If there are enough racers who need cars certified in the Sioux Falls area, we can hold a session at our shop. I need a car count,if interested call me @ 605 366-1032 . On another subject - Has anyone had success with the lite weight batteries (Brille or Odyssey) in their race cars?

Steve,

Any idea on what your dynamic compression ratio is? I am also interested to know if I can go to a lighter weight battery. Have a fairly high dynamic ratio and batteries seem to wear down quickly after a few starts. Trying to know what will work for final rounds w/ little or no time to charge. It is a "stock" car.
