If they come stock on the motor, as it was approved....then its legal.
As I am saying, we tried to add them at Paved nats in 2004.....we were told NO, after a phone call was made to double check the rule.
At carpet nats 2004, earlier that year, it was not allowed....
In 2005, it was again stated it was not legal to do it at both carpet and paved nats....
Bob Ingresol the techincal director was at a couple of the events........
Not sure what the point of adding them is really......if yer stock motor is getting that hot, yer doing something wrong.....all it does it raise the cost and add weight........they look cool though.
Not sure about it, the rules are vague at best.....in the end though, if it is legal, doesn't make much sense to not allow it at the 2 biggest ROAR onroad races for the last two years.
