A few things of note:

- SFI 3.2A/1 or higher certification label or FIA 8856-2000 homologation are REQUIRED now. Underwear required unless FIA or SFI 3.2A/5 or higher.
- On-board fire systems minimums changing 1/1/09
- FIA belts must have expiration date (no more 5 years, as I read it)
- 2-inch shoulder harnesses for HANS deleted?
- ECUs free as described prior.
- Dodge Shelby Charger to ITB

- (Proposed)VIN rule NLA, effective 1/1/09 (why not 08???)
- (Effective 12/1/07) Triumph TR6 to ITA
- (Rejected) Publish the weight process (Miskoe)
- (Rejected) Allow jacking points (Miskoe)

I'm all for changing the VIN rule - but isn't this going too far:

Improved Touring
Item 1. Effective 1/1/09, change section 9.1.3.C by deleting the fifth paragraph as follows:
The Vehicle Identification Number (VIN) shall correspond with the automobile classified, and will determine the model and type
for competition purposes. A minimum of two (2) VIN plates and/or stampings is required.


It would appear to me that we now have no formal method of discerning one vehicle from another - or is this covered elsewhere?

You're assuming the VIN provides an easy method of discerning the vehicle now.

We police it as we always do: inspecting the equipment appropriate for the car/class. If it's an Integra, we make sure that they don't have a GS-R engine and trans in there, just as we do now. The VIN requirement doesn't change that, nor does it currently stop people who want to from cheating.

We have well-vetted this discussion in the past, and there are two distinct camps on this. Here's but a few.

I'll start a new topic on this, so this one doesn't get muddied up. - GA

Seriously? So my 3.5 layer Nomex III, PBI, Nomex batt, 3.5 oz. Nomex tricot suit isn't safe enough now?

Argh.

Best I can tell, yes. New rule reads as follows (effective 11/1/07, which means if someone used something else at the ARRC they were illegal...any typos are my own...)

Effective 11/1/07: Change section 9.3.19.A as follows:
Driving suits that effectively cover the body from the neck to the ankles and wrists. One piece suits are highly recommended. All suits shall bear an SFI 3.2A/1 or higher certification label or FIA 8856-2000 homologation. Underwear of fire resistant material shall be used except with suits carrying FIA standard 8856-2000 or
SFI 3-2A/5 or higher (e.g., /10, /15, /20) Certification Patch.

[Knestis]

Well, that sucks. Gives me even more reason to really dislike SFI. Thanks, Club.

- 2-inch shoulder harnesses for HANS deleted?

[/b]

Negative. You just have to use the 3" belts if you are NOT wearing a HANS.

[vr6guy]

the only patch I can find on my barely used suit is as follows..... FiA NORME 1986/1986 STANDARD
04.257.CSAI.99

Someone tell me that my suit is up to standards?!

Thank you Miskoe for trying on the jacking points. This has been debated on here before as to whether or not you can fab something that may or may not be legal. We need jacking points in the GCR. It is a necessary item to keep from destroying your undercarriage. A jack, even the low profile aluminum one I have, will not get to my front crossmember or rear differential. Expecting me to roll onto some 2 x material each time I need to lift the car is a bit much.

There are 16 new glossary terms, including the words "metal", "removal", "addition", I guess we may need shift knob defined after all.

Triumph TR6 in ITA! Woohoo baby!

I see Spec Triumph as the next big thing!

I can see it now...a 10 lap race at VIR with 30 Triump's racing and not a one makes it to the finish line. Of course Jeff you weren't entered.

[lateapex911]

It'll be a throw down, and if any of 'em can make the sprint race distance, we could be impressed!

[Greg Amy]

(Two posts moved to VIN Rule discussion...thought they were good points and should be added there...)

[JeffYoung]

Sorry for the threadjack....

I ran an "All Triumph" Vintage Race (the Gold Cup) at VIR in 05 I think. ABout 40 'Umphs of all types. Race was six laps. I think maybe a 1/3 of the field did not finish. I turned out of Oak Tree and went down the back stretch on the last lap with some TR4 or something running like 15:1 compression. Car's motor exploded in front of me. It looked like the nascar in car stuff, so much smoke I couldn't see, couldn't tell where he was or even where I was.

Spec Triumph, probably not a good idea......

Back on topic.

Let the games begin.

- (Rejected) Publish the weight process (Miskoe)
[/b]

Glad I'm not the only one. Maybe if people keep requesting this they'll get the message.

- (Rejected) Allow jacking points (Miskoe)
[/b]

Open ECUs, but no jacking points? Whatever. I'm having my cage modified to have the plate extending down on the inside that touches the floor, but isn't welded to the floor so therefore isn't considered an attachment point.

"The engine management computer may be altered or replaced. A throttle position sensor and its wiring may be added or replaced. A MAP sensor and its wiring may be added. Other existing sensors, excluding the stock air metering device, may be substituted for equivalent units."

OK, calling all rules experts (Andy, Greg, et al). Does this mean I can replace the stock AFM in my '94 Miata with something else that is "equivalent", but has less flow resistance? I.e., is the definition of "equivalent" as ambiguous as it appears? (depends on what your definition of "is" is?)

[Greg Amy]

Lea, read that again:

Other existing sensors, excluding the stock air metering device, may be substituted for equivalent units. - GA

'stock air metering device', isn't that the throttle body? I know the way the statement is written, it makes it out as if the stock air metering device were a sensor, but I'm not sure how that works. I know on a CIS VW, the only thing that meters the air going into the motor is the throttle body. But it's certainly not a sensor.

Bill, many electronic engine control units measure the air volume entering the engine with a dedicated sensor - Mass Air Flow (MAF) sensor, Air Flow Meter (AFM), etc. Mine is a spring-loaded flapper door attached to the air filter - two feet from the throttle body. These sensors have a well-defined maximum area that causes restriction in the intake. A common upgrade for the street tuner is to replace the sensor with a physically larger unit to reduce the restriction. The rule says if you've got one, it must not be removed or modified, and all combustion air must flow through it. IMO this is the most important part of the new rule to minimize unintended consequences.

Is "metering" a noun or a transitive verb? Very important distinction...and given I know an English teacher quite well, I'd suggest you'd not like the answer...
