on im new to the sport. and im trying to get my car into proper working condition, because my car sat for 2 years. i was reading the solo 2 hand book for novice and it said
"Your car must be quieter than 95dbA (RLS) measured 50 feet from the course at a place where you are under full throttle. Due to the possibility of losing sites for noise problems, this rule is strictly enforced. (If your car is quiet enough to avoid attracting Police attention, it will most likely pass the noise requirement)"
my muffler is probably louder than that with a silencer on it. so my question is that even with all the work im doing to my car to get it up to spec i still can not race because of my muffler.

 

What car and muffler system do you have. A 93 integra ? I doubt that it will be that much of a problem causer.

 

yes the car is a 93 integra the muffler is a tusudo and the pipeing is 2 1/4 from the cat back.

 

What about the rule are you unsure of? It's pretty explicit.

exhaust > 95db = you go home.

 

Most clubs don't carry a sound meter to autocrosses. Use your best judgement and consider WHERE you are autocrossing. CFR's Brooksville site is at an airport, as is the PCA site in Zephyrhills. Noise isn't much of a concern there. A location that is closer to residential will have the event organizers paying more attention to noise.

Bottom line: If *you* think it's too loud, it probably is.

 

i've heard many a car well over 95db & none were sent home, there's no way your car will be louder than bledsoe's sm2 beast (the swapped mr2)

 

Jeese Leonard - Is it that time of the month or something Let's cut the newbs a LITTLE slack. The question is, how loud is 95dBa at 50ft? The answer is, It doesn't matter. Unless the car is louder than the loudest Harley you've ever heard it's not louder than any of the CP cars that were at the National Tour last year and SCCA did have a dB meter there. No one was tossed.
Bottom line - come on out and drive. If there's something wrong with it, someone on the event staff will tell you. It's pretty laid back. Sound requirements anywhere SCCA west coast events are run really don't have a huge concern about sound levels. GCAC in Ft. Myers does, but again, you can be pretty loud and still be okay. If you're really worried about it, come out to an event and stand next to Jim's V6 MR2.

 

thanks guys for all the replys. i will see all of u out at an event when i can get off of work.

 

The only organization that is concerned about noise is the GCAC in Ft Myers, nobody else seems to worry about it.
