Mike if the engines are lasting two seasons then you guys don't have a problem. If someone wants to switch engines between qualifying and practice, big deal. It sounds like Wren has it right.The CRB/FSRAC is not looking to make changes if they are not warranted and properly justified.This is such a non-issue that it isn't worth worrying about. I can't imagine how it saves money. People swapping their engines before the race are doing it because they don't understand these engines. Swapping your Kent or Pinto is worth it, swapping your bike motor is pointless unless you have hurt it.
