SCCA Autocross #6, Dallas Raceway, 8/12/12

BTW guys, did anyone's sound readings seem a little high compared to other events attended. We have never been louder than 97db's and we were told we blew 104db's Sunday. As well nothing has changed and Flowmaster's don't get louder over time so I am going to attribute the increase to the wind blowing? or the grandstand echoing?

We were definitely higher than normal as well.

The NSTR 7 car (red Miata) had sound at 106+. Almost everyone was covering their ears when that car ran.
If you are on this board we would like you to come back to the events but your car is TOO loud. It might sound
good inside the car but outside the car it does not sound cool at all.

The driver was spoken to by both the Sound Chief & the Solo RE. He says he's going to put another additional glasspak on the car before returning to one of our events.

My readings were almost 8-10 dB higher than at any National event I've run with the same setup, including the Colorado Tour, with cooler temps and much lower humidity. I am of the opinion that the sound readings were "more strict" than what the SCCA will ever demand at one of their big events. Still, it is very important to avoid the public perception that autox is loud. I feel the #7 car should not have been permitted to take more than 2 runs, and only that if something had been done to mitigate the sound after the first run. It wasn't even a close call.
