This week I participated in the Hooked on Driving, HPDE event at Mazda Raceway at Laguna Seca. Having never driven at this track I was assigned a coach to help me learn the line and teach me the braking and power zones. There was a noise restriction at the track of 92db for the day.
During my first outing the wind changed direction so that it was blowing directly at the microphone that was halfway up the hill between turns 5 & 6. On my 3rd lap I was black flagged for being at 94.6db. The car is stock so I was very surprised that it exceeded the sound limit. You can see the black flag to the left side at the end of the video.
I ended up short shifting the rest of the day – my speed improved through 4, 6 and 10 and I found the right line by 3rd session on the track.
