I am new to this forum so I will ask some very basic questions first.
Q1.) Who began the Super Street (10.90) class, the IHRA or the NHRA ?
Q2.) What year did Super Street begin?
Q3.) Was there ever an 11.90 class?
I believe one of big US sanctioning bodies (IHRA perhaps?) ran such a class in the past
