The NJBA and other professional racing organization do listen to the public’s opinion weather it agrees with the existing rule or controversial opinions.
The NJBA does have the option to exercise part 2 of establishing a class based on that E85 Fuel and if there is a need to create a class that will be sustainable. Clearly the fuel is intended to reduce hydrocarbon and other negative effects to the atmosphere and is EPA friendly.
There seems to about 12-16 people who are at odds as to what class does this propellant fit!
How does this sound?
