Though not listed in the above quote the following does exist in the 2011 rule book Apendix I page 280. "Any run (XX) dBA or over will be scored a DNF." in the case of San Diego (XX) = 93

Note: Itallic was added by me.

well there's the problem. I can use google docs from my computer. so i never read aaron's link.

how nice of the national staff to give us 10 days notice to redesign our exhaust.

It's the sound rules that have been posted on the scca site for the tour, they just didn't change the DB in the doc, but did post that the sound limit would be 93db for the event. The turn down wording has been in the supplemental sound rules since that fastrack was posted. Glad I posted these to draw people's attention to them.

Generic tour sound policy is one of the links on the right and has the turn down wording.

So, sounds like you can't redirect IF it is a repair action. Otherwise, redirection isn't limited.

That's how I see it, too. Once I see where the meter is I can redirect prior to running. I will actually start with the existing exhaust that exits straight back. Then can switch to one with a turn down, directed where necessary as it's installed. Then if necessary I can switch to a quieter intake filter since much of F125 noise is from the intake. This all assuming we don't get DNF's for over 93. I know what worked on my kart, not sure on Ron's.

This is interesting. If you read the Appendix that Craig is referring to you find the following:

STANDARD
Maximum limit of (XX) dB, A weighted, at the measuring point.

and

Any run (XX) dBA or over will be scored a DNF.

So, if I run the actual limit, I get a DNF? Seriously? So everyone at the Tour has to be 92.9 or below to keep their time?

Do the Supps override Appendix I?

Remember though, once you make a "repair" you can not change it for the next day. So be careful. I take pictures to document any repairs and mark down on a notebook what was changed and on what car.

Read the first line of appendix I.

Which is

The provisions of this section are recommended, but not presently required.
The specific DB levels (values of “XX”) are expected to be assigned
by Regions according to the needs of their sites.

Somebody needs to re-write that though. Getting a DNF for running the maximum limit can't be what was intended. I'll write a letter.

Like you take pictures of your hotel room number when you go out partying? You're like that dude from the movie Memento.

Hey it's what they had me do when I was a chief of sound at nationals, haha... and heck yeah, always set your phone's background to a pic of your room number.

I actually thought that was brilliant! :ibrightdea: If you're so drunk you can't find your phone or figure out how to access the photos, you deserve to sleep in the hallway.

The rule dosen't state the limit, maximum, or any other such wording as to what you CAN do. It states the point at which your sound is a problem. In San Diego that's 93 where you have a problem, at Nationals it is 100.

I think it's pretty clear.

Same rules as nationals last year on that, DNF is automatic on the third fail, but it's up to the Op steward and me whether your repair is enough for you to even get another run. If we don't think it'll be enough for you to pass sound we don't have to let you run again. We want everyone to get their runs, all i'm saying is, don't try and game the system.

I've lined up a couple of fixes... Its strange in that I can't really risk using them from the onset, because by the rules I need to have at my disposal some legitimate fixes.

WTH? Now there is a chance of rain predicted for Saturday night into Sunday morning! Glad I'm running in the afternoon. Based on today, I thought summer was here...............

I meant they need to re-write the part we mentioned above, where they DNF you for being at (not over) the maximum.

maybe you are looking at the weather for the pro? I've seen to mention of any rain this weekend.
Was in the 80's today at the Q.

Local News (TV and Radio) is really talking up the change were due, vs. the 90's across most of LA today. Stating rain "possible" Saturday night, into Sunday morning. Haven't heard a single one put odds on it thought... today's weather word of the day appears to be "possible". Weather.com currently (3/31/11 10:45pm) puts that chance here in LA at 10%, SD is listed as 20%.

Local here is saying possible clouds Sat night... but otherwise fine all weekend.

We need this weatherman

Okay unconfuse me:

Standard SD rule is to DQ any run over 93dB. Barred from further runs unless physical change is made, but redirecting elbow is legal (Or at least common).

National Tour rule is no DNF for first run over 93dB, but you have to make a change other than redirection to make a second (or third). Assuming you're allowed to run there's no DNF until last run.

Do we agree both those statements are true and the second is what will be used? I can see them enforcing the first version since that's their norm. Or even enforcing them both intermittently throughout the event.

But the Sound Steward is a non-San Diego person therefore, more likely to enforce the National Tour Rules.

Good Luck Everyone!

The national staff (Sandy) has handled the sound DSQs in previous years, so the same person will be making the decisions all weekend.

I would like to thank everyone who attended the tour. We had a lot of chiefs from Cal Club and could not have put on the event without your help.

Thanks to Scott, Jason & Marshall for being stewards.
Thanks to Aaron for doing a great job with sound management. We did use the national sound rules with a 93 dBA limit.
Thanks to Christine and Craig for doing a great job running impound & grid.
Thanks to Sebastian for being safety steward and KJ for being youth steward.

No rain & no protests.

See you all at the Pro!

Thank to Mark for putting on an excellent event!
