SFR's limit is 95 at 100, and we haven't had any street tired cars come
particularly close to it. Last time I was measuring at 50 feet (for a Laguna
Seca special requirement) all the cars above 90dB were noticeably engine noise.
I suggest you talk to our Sound Czar, Don McKenna,
mailto://donbarbmckenna@earthlink.net for better/more details.
