Good to know us 1.8 NA guys may be able to repair our exhaust manifolds soon, wording should include repairs on exterior of collector portion of manifold...where they typically crack!  Oh, and fix the tabs that break off too!

Thanks for making this clear. I had left out "Recommended Items for 2016" and it looked like it was not recommended above.
I fixed it.

CLUB RACING TECHNICAL BULLETIN

GCR
1. #18687 (Charles Tanck) Proper Interpretation of Section 9.3.41. Seats
In GCR section 9.3.41, add the following language:
“The driver’s seat shall be a one-piece bucket-type seat and shall be securely mounted. The back of the seat shall be firmly attached to the main roll hoop, or its cross bracing, so as to provide aft and lateral support. Seats that have been homologated to and mounted in accordance with FIA standard 8855-1999, or seats that have been certified to FIA. Standard.8862-2009 or higher need not have the seat back attached to the roll structure. Seats with a back not attached to the main roll hoop or its cross bracing may be mounted on runners only if they were part of the FIA homologated seats assembly specified in an FIA homologated race car. The homologation labels must be visible. Seat supports shall be of the type listed on FIA technical list No.12 or No. 40 (lateral, bottom, etc.). Passenger seat back–if a folding seat, it shall be securely bolted or strapped in place.

 

Effective June 1, 2016- Upon expiration of FIA certification, FIA seats may be used but must have the seat back firmly attached to the main roll hoop, or its cross bracing.”

Spec Miata
1. #18663 (SCCA Staff) Compression Ratio Calculator
The CRB/SMAC/Staff have been working on a new 1.8 Spec Miata compression ratio calculation spreadsheet. The new calculator is simpler and easier to use for engine builders and technical inspectors and also includes error checking.
In section 9.1.7.1.a, add a new section as follows:

 

“3. Compression ratio for 1.8L engines shall be calculated using the official Spec Miata calculator. The calculator can be downloaded on scca.com: http://www.scca.com/...orms-procedures”

2. #18957 (Spec Miata Committee) Omission - disallow VVT extra bracing rule
In GCR section 9.1.7.C.3.c., add the following language:
“Subframe braces maybe updated to stock 1997 configuration utilizing the MAZDASPEED Motorsports Development Spec Miata kit.

 

2001-2005 (VVT) model years must remove the additional intermediate underbody/floorpan attached bracing (Mazda part number N067-56-G11A Base plate & part number N067-56-H10A cross member).”

3. #18994 (Jason Kohler) Clarification of 9.1.7.C.3.h Regarding De-Powering Steering Racks
In GCR section 9.1.7.C.3.h., make the following changes:
“Manual or power steering racks may be used. Power steering racks may be converted to manual by removing all power steering components and the 2-piece pinion shaft may be welded. Removal of power steering components is allowed.”

1. #18452 (Jerry Hodges) Limit Majors to 3 Days (Including Test Day)
Thank you for your request. SCCA should not dictate to the host region the length of events because it may have adverse financial impacts on their racing programs.

[Mark McCallister]

How would any region lose money by having a shorter event?  Seems like the long 3 day race weekends + 4th day for test day probably keep more people away than they attract?

That could be true but not at Mid Ohio for sure. Most regions rent the track for the race days and the track puts on the test day, I would say if they could get the event done in two days vs. 3 they would make more money in my experience. In asking our region why we are doing 3 days for the Mid O major out problem was getting it all in due to high number of participation this year.

 

I will say however, if your unhappy with a 3 or 4 day format including test day, you need to tell the Region not the CRB.

[davew]

Actually Frank, the CRB does have some responsibility in the program. The rules the local regions must adhere to, in order to get a sanction number from SCCA, require specific minutes of track time per class. And there are guidelines as to which classes can be combined. And guidelines on how many cars can be on track at any one time (cars per mile). Couple that with track rules for hours of operation and local rules for quiet times, and you run out of hours in the bigger events.

 

You simply can not get the minutes of track time, times the number of groups, with the correct mix of cars, within the cars per mile rule in a 2 day event. The problem is the success of the big events.

[FTodaro]

I do not disagree Dave, we both know that the region is dictated to by national, on many issues, better I said talk to both.

[Johnny D]

Dave, so Butches numbers reflect the max the cars per mile or combine one more group and you'd be over ?
I hope I didn't take anything out of context.

The BoD/CRB have talked about combining classes since I first started paying attention and there were 21 classes at the 1971 Runoffs. It's easy to talk about combining classes when yours is not going away ("Make the other guys change, Spec Yugo is fine") but the reality is it's unlikely to happen in my lifetime. If this were in effect based on 2015 participation, here is one potential way the groups could be formed:

SM (62), SRF (39), SRF3 (29), and STL (37) are standalone.

AS, GT3 (22 + 11 = 33)
GT1, GT2 (11 + 27 = 38)
FA, FB (10 + 20 = 30)
EP, GTL (29 + 10 = 39)
F5, FV 16 + 30 = 46)
FC, FE (11 + 16 = 27)
FM, FF (10 + 25 = 35)
P1, P2 (10 + 17 = 27)
HP, BS (18 + 15 = 33)
FP, STU (21 + 18 = 39)
T1, T2 (12 + 20 = 32)
T3, T4 (5 + 22 = 27)

All the multi-class groups would have a split start, so most of the concerns about running similar lap times in very different ways would be greatly reduced.

Edited to add counts from the Daytona Runoffs...

I know how that feels.  Must be a clerical error.  

[davew]

Frank, I know that you know. But others reading this are not as aware of the inner workings. Thought I would clarify for everyone.

 

Johnny, I am not 100% sure, but what I have been told, is that the maximum number of cars per mile is 25. With a slight fudge factor at the Chief Stewards discretion. I am not a steward, so I do not have access to all the paperwork, but I have stayed at a Holiday Inn before.

[Johnny D]

I thought it was dictated by the track insurance(cars per mile), but I'm not sure either.

[wheel]

Here's the rule

 

General

 

Number of Cars allowed on Course

A maximum of 25 cars per mile may be on the course or started simultaneously in any type of session.

The Division’s Executive Steward may increase or decrease the 25 car limitation for any or all race groups. 

 

 

The GCR does not give a reason for the rule.  

[FTodaro]

I have not seen the SCCA Policy, i have seen the PCA policy. I doubt that the insurance folks would have the expertise or interest to direct such a number. Most likely coming from the clubs, with some help from the Track. The track may have limits based upon their assessment of risk and flaggers on hand.

[Johnny D]

That make sense, club dictated, because LeMons has 8 gazillion per mile.

You guys have the most rodeos under your belts. When do the complaint start to raise ? 40+, 50+ cars or depends on the run group?

Check out the Mid Ohio Majors (or as some would say if rainy Mud Ohio, sorry Frank it's a truth) June 3rd thru the 5th pissing match in the production race group.  http://prodracing.co...=16974&start=60

 

E, F, H, GTL race group 89 cars

 

STL, STU, T2, 3, 4 54 cars

 

SM 53 car    Interesting, no one from the South East. Per rumor mill a bunch doing the NASA Nationals rather than the Runoffs, hence maybe doing a weekend at the Nationals track.

 

338 cars total to date and race is 2 months down stream.

So what's your prediction ?

2.4 mile, so 60 cars per run group ?

Tears or cheers ??
