This is from the 2024 SCCA Solo Rules, which have been recently updated (the old info is crossed out) APPENDIX H - SOUND MEASUREMENT PROCEDURES AT SCCA® NATIONAL SOLO® EVENTS The maximum allowed vehicle sound level will be 100.0 dBA. 108.0 dBC. The measurement will be taken at a point where vehicles can reasonably be expected to be under load at full throttle. The measuring point will be 50 feet from the edge of the course using an ANSI Type 2 sound meter set to “A” “C” weighting, “Slow” response. The microphone will be 3 to 4 feet above ground level, positioned perpendicular to vehicle direction of travel. The microphone will be away from structures (e.g., buildings) as is practical. If a driver in a vehicle exceeds 96 dBA 100.0 dBC, the Chief Steward or his/her designated representative will be notified by the Sound Control Steward or representative. The driver of any run producing a sound measurement over 96 dBA 100.0 dBC will be notified, as soon as reasonably possible following the run, by the Chief Steward, Sound Control Steward, or representative. If a driver in a vehicle exceeds 100.0 dBA 108.0 dBC, the driver will be allowed to attempt a viable remedy to functionally alter the exhaust system to reduce the sound level of the vehicle before his/her next run that day. (A “mechanical delay” per Solo® Rules Section 6.8.D may be used.) If the excessive reading occurs on the driver’s last run of the day, the Chief Steward, Sound Control Steward, or designated representative is authorized to impose a DNF penalty on that run. The use of an adjustable directional exhaust exit to laterally aim the exhaust output away from the sound meter position does not constitute a viable remedy. Adjustable directional exhaust exits may only be aimed straight up, straight down, or straight back. If a viable remedy has been attempted in the judgment of the Chief Steward, Sound Control Steward, or representative, the driver will be allowed to take his/her next run. If the driver declines any viable remedy or if the change is deemed inadequate by the Chief Steward, Sound Control Steward, or representative, the driver will forfeit all subsequent runs in the vehicle (unless an approved viable remedy is completed before the next run). If the driver in the vehicle exceeds 100 dBA 108.0 dBC again on any subsequent run, that run will be scored a DNF and all additional runs the for that driver will be forfeited. If a sound violation which would incur a DNF occurs on a run for which a rerun would otherwise be granted (per Section 7.4), the sound-based DNF will stand and there will be no rerun. For the purposes of sound measurement and enforcement, a “run” is defined as any attempt at driving through the course, whether or not it is scored or a rerun is allowed. Any functional remedies implemented to reduce the sound level of a vehicle may not be removed (including the next day of the event) and may be subject to re-inspection by the Chief Steward, Sound Control Steward, or representative. If the remedy has deteriorated after passing the sound level requirements at the measuring point, the sound level of the vehicle must be functionally addressed again. The Chief Steward, Sound Control Steward, or representative has the right to disallow a repeat of the same remedy that deteriorated. The remedy may be changed or modified to improve its quality and/or further reduce the vehicle sound level. Drivers that receive a DNF for non-compliant sound levels implement additional functional remedies to reduce the sound level to compliant readings before starting runs the next day. These general sound level regulations will NOT override specific local area and/or SCCA® Regional sound level requirements, regulations, and/or penalties.

This is from the 2024 SCCA Solo Rules, D. A passenger is allowed provided they: 1. is no younger than twelve (12) years old or is at least 57” tall; 2. is in a vehicle which has passed safety (tech) inspection (Section 3.3.3); 3. is wearing a properly fitted seat belt and a properly fitted helmet; 4. has completed and signed the required participant waiver(s), including parents/guardians as appropriate (Section 4.13). The only passengers who may be allowed during competitions runs in National Solo® events are non-competitors whose role is to fulfill the state-mandated requirements for a driver who has a restricted driver’s license requiring a passenger. I wish the ASN rules were the same as the SCCA rules in more than just this area.

This is from the 2024 ASNAutoSlalom Regulations, 4.1.2. To be eligible to participate as a passenger, a person must: a. Have the consent of the organizer; b. Have signed the Stoneridge General Waiver; c. Wear personal safety equipment as required for the driver; d. Keep hands and arms inside the vehicle at all times; e. Not carry items such as food, drink, cameras, video recorders, purses, etc. The items listed above must be presented at the time of event registration and/or scrutineering inspection. 4.2. Underage Participants Participants (drivers or passengers) under the age of majority for the province in which the event is taking place must also present a completed Annual Parental Consent Waiver at event registration. In addition, minors participating as passengers must: a) Be at least 14 years old; b) Be in a vehicle being driven by their parent or guardian;

This is from the 2024 ASN AutoSlalom Regulations, 5.8 Noise Limit Adequate muffling devices must be installed on all vehicles with a sound level to a maximum of 96 decibels unless there is a lower noise limit required for that facility/track listed in Appendix I, or in the Supplementary Regulations. Organizers may apply to NSC for lower noise limits if the facility/track requires. Such limits must be sent out to all competitors in the Supplementary Regulations 60 days in advance of the event and must be posted at the site on the day of the event. Please note that some facilities require a lower decibel reading and, in order to compete there, vehicles will have to abide by those lower decibel limits. 5.9 Noise Measurement Measuring shall be done from a distance of 15 meters perpendicular (50 feet) to the vehicle wherever safe to do so. The final decision as to adequacy shall rest with the Steward. Any vehicle deemed to be excessively loud must not be permitted to compete without acceptable modification being made, regardless of the existing exhaust system. Please note that some facilities have their own measurement procedures and, in order to compete there, vehicles will have to abide by those measurement procedures. Event organizers should include a notice in the event’s supplementary regulations when such measurement procedures occur.

We are not planning on any test and tune days for Autocross. I will post when the first events go up on MSR.

Member 5603, keeping #74.

Of course. I will get in touch with Helix and have him start the yearly thread.

What time do the meetings start? I checked back over some previous meeting posts and none of them have a time.

Yes. They will suffer.

Passengers were allowed the previous two events and should still be this weekend. If they aren't competing they will have to register as your crew on MSReg.

The updated version I was emailed two days ago still has all the same strict restrictions. Not sure why it isn't posted here yet. I agree with you that the policies should be relaxed due to new info and trends.

How does the washroom rule apply to autoslalom at St.Andrews? Shouldn't that be in some supp regs somewhere and not applicable to all disciplines? That's not my only issue with the policy and practices but it's the most obvious one.

They're also 2wd so not exactly relevant to the thread. @BeauHow "irreparable" is the leak? Years ago I had a daily driver (no autox use) tire with a leak in the sidewall (irreparable) and I had it patched anyway, no warranty of course, and it held until I replaced the tire ~6 months later. If that isn't an option, I would replace a pair, front or rear, if you can find something close enough in diameter. I'm thinking about a table with two pairs of legs that are off by 0.5". I'm putting them on the same end.

My answers apply to autox only. There is no broom handle test required. Open face is allowed. But, I would suggest a closed face. I've had things hit my visor/helmet even with a roof over my head.
