This is copied from Loud exhuast at Lime Rock thread post #49!
Here it is officially: 03/03/11
From: Skip Barber, Georgia Blades and Scott Mayo
As you know, exhaust noise has always been an issue at Lime Rock Park. We operate under a 1959 Court Injunction that stipulates: the number of weekends (10) that we can run unmuffled; other times we aren’t restricted (Tuesday afternoons); the decibel limit for all other track days; and bans Sunday track use. There have been no changes in the injunction and we don’t anticipate any court ordered reductions in noise levels. But we have growing criticism from some of our neighbors; some of which is justified:
1. Significant manufacturers like Porsche, Mercedes (AMG), and Ferrari are building street legal cars that at high speed and full throttle are “on the edge” of our required decibel limit. Given the right atmospheric conditions they go over the edge
2. There has been a major increase in the number of small manufactures building great track cars that are too noisy “out of the box”
3. More and more of our track users have cars in these two categories
4. The Skip Barber Racing School has steadily increased its use of “noisy” Miata’s rather than relatively quiet single-seaters
5. There are a small number of SCCA race cars, mostly Porsches that turn up at multiple club events for “cheap” practice. They almost always need to “test” their “improved” exhaust systems, making too much noise in the process
For 25 years the track set a limit 1 dB level below the injunction requirement to be safe and never exceed the mandated limit, unless the exhaust system broke. Cars were checked while stationary, before going on the track, 1000 RPM below the redline, and theoretically never got on track if too loud. There was no on-track testing to check for compliance as there is now. Porsches had the most trouble complying and it was common to have a Lime Rock exhaust system.
Over the years the 1 dB margin has vanished and on-track testing has replaced stationary checking. A common scenario is that a car runs 4 or 5 laps; is too noisy; comes in to correct the problem (often with steel wool); goes out again; the steel wool blows out after a few laps and it takes a few more laps to get the car in. Then the process starts all over and by the end of the day the car has run multiple noisy laps.
And now we have more complaints.
We are going to deal with this proactively:
· We are going to reduce the total noise
· We are going to have a sound engineer calculate the total reduction
· We are going to tell the town what we have done and we are going to stick with it
We are NOT:
· Going to court to try to change the injunction
· Going to complain about the injunction
· Going to criticize the states motor vehicle laws or the measuring system
· Going to make the economic argument that the town needs a viable track – they know that
We want to stand in front of the town and say:
1. The total noise is down_____%
2. All quiet days are quieter
3. Even the biggest professional race, the American Le Mans Series, is down 2 dB
We are going away from a “one size fits all” dB limit; assigning every club a limit we think is reasonable in terms of cost, impact on performance, and effect on entries. We know “reasonable” doesn’t always mean “easy” or “cheap.” The new limit, effective immediately for your club, PCA is 88 db.
The two big problem groups are the school’s Miatas and some Porsches, regardless of what club they run with. The school is fortunate – they have a new sponsor, Borla, who is building them all new complete exhaust systems. They have already tested under 83dB, their new limit at Lime Rock Park. This is a tremendous reduction – they have been running 88-89 dB, and they use the track more than 100 days each season.
Not so easy for some Porsches, so all Porsche clubs go down 1 dB; but we are going to rigidly enforce this. This 88dB limit is for non-race Porsche days – not for Porsche cars regardless of what club they are running with. So a Porsche limit would be:
88 dB Porsche Club Day
105 dB Porsche Race Day
87 dB BMW Club
86 dB PDA non-race
88 dB SCDA
88 dB Lime Rock Drivers Club
105 dB Tuesday afternoon Test & Tune
PLEASE don’t let anyone come for testing or a club day with an unchanged car that was too noisy last year. This isn’t about “beating the system” by short shifting or lifting off the throttle while being checked. This is about lending real meaning to the phrase, “We’re all in this together.”

Try not to wait until the last minute guys & gals.
The sooner you sign up the sooner someone that has been "waitlisted" gets into the event.
Thanx All.

Still have room in red/black.
Two FULL days at Lime Rock.
If you guys/gals don't know, LR is now a private club and any clubs that do manage to get some time there are usually only 1/2 day events.
