AMP Racetrack

[roadracer67]

AMP race track in Phx, AZ is in the process of reapplying for their permit to operate. Some of the provisions are:
- 2 sound monitoring stations that the county will be able to have real time feed on.
- No more than 500 people. This would include all racers and their crew.
- 80 decibels. Absouletly nothing louder and people in the area are saying even that will be to loud!!!
- Limit on how many days a year the track can be open.
- NO PRO EVENTS
- No viewing stands, no over night camping
And they have to improve the road at the entrance to appease the neighbors.
This sucks. The track is 10 minutes from my house. The people doing the most complaining live right next to Luke AFB. Don't hear them complaining about F-16 taking off every day!!!!

Sucks is right.  And let me guess -  the track was there before the houses.

80 dB?  I guess it matters how far away the sound monitors are from the track, but I thought the federal regulations were 82 dB at something liek 50ft.  And that fed regulation is a a set speed in top gear (65 mph?), so a stock bike that meets the federal regulations might be well above 82 dB at redline.

Would make it very hard to hold any type of "race", my bikes sure wouldn't be legal.  My TZ has "stock" pipes, there isn't anything I can do to make it quiet.  

The same will be true for the car guys, my street legal Triumph is louder than many folk's race bikes.

I think it's 80dB at the property edge.  

Walls (not on the track) and 102dB cans on the bikes and cars will work - you'll drop 6dB or more every doubling of the distance from the bike.  With walls, I bet you could be down at 80dB at 200Hz easy, but I haven't ever seen the track.

I could live with racing with stock exhaust or quiet aftermarket.  Especially for a track 50 mi from my house, all freeway miles...

And, last but not least, Luke does not fly on Sundays unless there is a national emergency.

Wrong!!!!!  Luke doesn't normally fly on Sundays but there is nothing preventing us from doing it.  Besides we work Sundays at least twice a month and we can be doing engine runs and running loud equipment on either day.

My father-in-law, retired Colonel in the USAF (retired "outside the gate" up in suprise) had said this.    Do you fly 'less' on Sundays?

[roadracer67]

Unfortunately I think no matter what sound level they get the track to go to it's still going to be too loud. The people complaining about the track live right next to an active military base. They have spent way too much money on their house and don't want any kind of noise what so ever. If the AFB doesn't fly much on Sundays, it is probably only to keep people from complaining.  

[Mongrel]

That's pretty much it.  Don't fly much on weekends to keep the complaints down, but believe me it would not matter one bit what is done because Luke gets complaints all the time.  Luke runs 24-7 but does have slow times.  With the shift to more night missions you can guess where a lot of the flying is done now and where the majority of the complaints come from.   Luke also deploy jets all the time from, as a matter of fact jets were launched out on a Sunday less then 2 months ago.  Don't let anyone fool you into believing that Luke is a nice quite F-16 Base, and that AMP is some kind of massive noise maker.  I am less then a ¼ of a mile from the track and can barely hear it over the normal Luke din.

AMP started having events in 2003. It had a permit for private use, the permit was pulled after local authorities found out that not all the events were private use.

As far as federal sound tests, they are done at a specific rpm at full throttle, not a specific speed (there is a formula to calculate the rpm - includes redline and final gearing - I have been present at these tests when I worked at Buell). The bike must be perpendicular to the sound meter when the rpm is reached.
