What with the db-level sound check thing? Is that some CA environmental reg stuff, or because the track is close to offices/apartments or something? I've never heard of a db-check at tracks here, and there's some insanely loud cars in the upper run groups at some of our DEs. A couple are just straight up tube-frame custom race cars that look like they belong in a NASCAR event and sound about the same, too.

It's usually related to the track's proximity to other property. Track's on the east coast have it as well as up in Canada. 92dB is a pretty common limit, and many tracks will black flag you if you go over the limit. This is the east coast list that I have.

NHMS: 99 dB @ 50ft (never enforced to my knowledge)
Mont Tremblant: 92 dB
Mosport: No limit
Summit Point: 103dB @ 50ft
Lime Rock Park: 86-88dB @ 50ft (depending on club)
Calabogie: 92dB @ 50 ft
Watkins Glen: No limit

Because the multi million dollar home owners have a louder voice than the track fans. The county has a strange db limit regulation, I do not know or understand. It is strictly enforced. Many of the cars have LS pipes, which are angled away from the sound booth on turns 5/6 uphill straight.

Our club last year got three 92 db days and they were much cheaper by $10,000 - $15,000 than this years 105 db days. $280 vs $170 although a big difference, made no difference in my attendance. Sell out at all events. It is a great track.

The club has been offered some 90 db days and rejected them as too low for club members to make. I wanted to find out where I was if we did take a 90db day and I came in at 85 db. Now I know I can go. Or screw with test pipes.

ChrisSlicks · 06-06-2013, 07:52 AM

I have the ART pipes since they are quieter than the alternatives, came in at 88dB at my last reading. I think straight test pipes would be a little higher, maybe right around 90dB.

Cool beans. I would have thought a worse reading. How much actual HP do you gain removing the catalytic converters?

10-15hp over stock cats I would say.

For street driving the biggest issue is hiss and rasp at lower RPM's, but once it's revving the sound is very nice.

Exhaust leaks are a problem though, the only gasket you can use that works is the metal gasket from Z1 which is similar to OEM design but perhaps stronger.

Here is my final Laguna Seca video post from Monday. It is my second run. I have another that is more of a warm up for me while I work on turn 2 with a double apex. This video here has the same, better worked out.

Laguna is the only track I've been to where the db level is the law and enforced. Houses seem to make the difference.

ok or no ok?
Have yet to figure out You Tube. Not enough time on it.

Btw: lost my credit card on sunday on my way home from autocross.
Very unusual behavior for me.
So i want to know what your mental state is after track days. It seems that i totally crash afterwards. Barely remember things and physically exhausted. Is this normal or am i working myself up -need to relax more while participating-not sure what is going on ... Help.

wstar · 06-12-2013, 09:08 AM

It's pretty mentally and physically exhausting. I normally do a lot of physical work around the house/garage every day and then also write software the rest of the day, and I still only sleep from around midnight to 6-7AM. On track weekends, I often get back to the motel from Saturday's sessions around 6-7pm and find it difficult not to just pass out on the bed immediately. If you're driving home directly from a track day (which I usually do on Sundays), it pays to take it a little easy on your final session or two.

Of course: it goes without saying that you should really pay attention to hydration and nutrition over these weekends, and try to get a few really good nights of sleep leading up to it. Drinking during a track weekend or even a few days before is out, too.

Sorry to hear about the CC

Mythbusters 2013 Episode Guide : Discovery Channel Refer to the "Race car driver can lose 10 lbs during a race" While I don't think they get quite that much in their results, it is obvious that driving a race car stresses both body and mind.

Wow I agree with everything to a tee.
My very first event was in the rain and I never ate all day I was so excited. I mentally crashed so hard I could not safely drive the last event. I felt wimpy but this may have been one of the best decisions of my life. Proper nutrition and hydration keep you mentally sharper. Fuel for you, just like fuel for the car, is just as true. I force myself to eat and drink.

One hour before I take a dramamine and a couple ginger pills. I take a 5 hour energy and again at lunch. This takes me till 5 PM and I usually feel pretty charged from adrenaline, I might be able to drive home 2.5 hours but my gal does not want to and have never tried. I think it a wise decision not to drive back actually, as I age I can't do what I once did, ie go for days without sleep.

A standard post event, might be to hook up with a few other drivers at Chilli's and decompress with stories of how and why. I like this best. Afterwards I can relax go for a walk and be asleep by 10 PM. Most other drivers go home after Laguna Seca. Sears Point is only 45 minutes away so I do drive home from here.

Temperature can play a role too. A 70-80 degree day is better than a 80-100 degree day for me. Actually for me 50-70 is best. I get too hot tired and sweaty.

BC20: Did you leave the credit card at the gas pump?
I review my camera footage to help with memory of the event.
The total mental crash has been lessened with more events under my belt which stand at 10 total. I am sure a good portion is the food and water, plus knowing how to prepare between driving sessions. I get gas, sit in the shade, talk to various people and know what time I'm on next. Seems simple but not stressing keeps me sharper and less fatigued too.

My only autocross type event, was an all day event followed by my 30th high school reunion which I attended afterward until about 10 PM where I got to the end of my rope. The drive home was also the first time the little lady complimented my driving.

A memorable day.

thanks Jar...it has been cancelled but not located (or used, which tells me it is someplace in my car or jeans pocket etc)...

Tam told me all this but I was so close to home the first time I did the auto cross I guess I didn;t notice. But Sunday! OMG! I am glad my little one was with her sister. I had a horrible time getting home (about an hours drive). very little to drink, NOTHING to eat until afterwards. WOW! if I could do it wrong it appears I did.

Sorry Tam!! I did not listen well to your lessons learned!!

see previous post. I DID NOT FOLLOW YOUR INSTRUCTIONS!! sigh. and I am still paying for it. Wednesday and still worn out. I feel realy stupid. But I will do it to the letter next time because THIS sucks the joy out of the fun I had 3 days ago.

(congrats on 10 events- experienced drivers told me time and again on sunday-seat time makes you better-don't rush it)
