Think Goodwood BHM day static test is 98db. Then if you are over/ near just be careful when passing the trackside mics- just throttle back a little or change down. My old AR throttle bodied 4/4 was always on the edge - they try to help you not go over when actually on the track by pointing out where to back off.
