Track Noise Restrictions (Road America)
Just got my confirmation email for Road America and it says that the "new for 2008" noise restriction of 103db will be strictly enforced. It would really suck to go all that way just to be shot down for loud exhaust.
Anyone know just exactly how strict they are about it?
Where could I get my hands on equipment to check it myself beforehand?
How do they check it? At a certain RPM? As you pass by at high speed? Do they just put a mic down by the tailpipe and have you rev it?
I'm pretty sure I'm legal since I do have a couple of small silencers but it is still pretty loud. I dont think I'm nearly as loud as a GT car so I should be ok.......right?

Radio Shack sells a sound meter that well do the trick. Contact RA and ask were they meter the noise and go from there. The height and distance from the car are very important to the outcome of the measurement. Also ask what units they measure, there is a dB A and dB C weighting. Ask if they use average readings or peak readings.

The last time I worked the race the sound check was between turn 3 and the bridge, on the outside of the track. I believe SCCA has specific rules on sound checks "X feet from the track at right angles". It was a distance from the track. Previously they did not move around although one year we were surprised to find the sound person was moving around. The track repositioned her.
103DB is pretty loud. If you've got a stock class car, my bet is you'll make it. If not, you may want to play with a set of exhaust tips, turned towards the right, assuming that the sound check meter is still on the outside of the track.
The issue for RA, as with a lot of tracks, is that developments are encroaching on the track, even though when it was built and for the next 40+ years it was out in the country. The price we pay to play at a great facility is to have somewhat quieter exhaust.
Frankly, we have had discussions on the PCA club racing rules committee about instituting an across the board DB maximum. I realize all kinds of racers will complain but frankly, if we can save one more track and in the process save the hearing of a lot of participants, staff, etc., it's worth it.

Frank, I "frankly" don't understand your post.
Are you saying either the implementation or the enforcement of PCA club racing rules is inconsistent?
If so, please give me chapter and verse as to examples.

Bruce Boeder

I'm driving a 1978 SC "D" car.
Have not had any offers yet for help learning the track during the test & tune day. You wanna help a brother out? Just looking for 2-3 laps to get an idea of the line. I don't want to take up too much of anyones time.

More gas and less brakes that should make you go faster...hook up with Jay W he will be there in his spbox and knows RA pretty well.

103dB is quite loud, especially if it is measured well away from the edge of the track.
