SFI President and CEO Arnie Kuhns called the meeting to order at 1:00pm. It was explained that existing specifications must be reviewed on a periodic basis to ensure their relevance to current field conditions. It was previously asked of the committee to submit in writing any suggested agenda items prior to the meeting. It was noted that attendance for this committee did constitute a quorum, therefore official business could be conducted. The comments of those in attendance would be heard and a report will be provided to the full committee.

The committee began by discussing the one agenda item that had been previously submitted: allowing a lower adjustment slot in a 6.1 bellhousing that would enable access for adjustable clutches without end users making their own holes or improper modifications to the bellhousing.

This would be for passenger car replacement bellhousings only. It was suggested to create a new separate spec for this application, such as 6.1W (for window). The following are all items that the committee would like incorporated into a draft:

In such a new spec, the window should be reinforced. The new spec would omit the wording about the adjustment opening being located past the rotating clutch assembly. There would be a separate sticker on the window itself. The window should be as close to the transmission end of the bel lhousing as possible, such as a 6.2.

It was asked what kind of clutches these bellhousings would be used with. It was stated it was mostly for Stock and Super Stock class cars and a dual disc would be the most discs they would use, with a relatively small diameter.

The bellhousing with the greatest depth would be tested to cover all like models.

The committee needs information for possible assembled clutch heights. Tim Hyatt volunteered to compile this information.

The committee needs to determine dimensions for the smallest useable hole size based on this clutch data and a shallow bellhousing.

The window will have to be located on the lower quadrant because it’s for a passenger car application.

The spec should require a recertification life to prevent unauthorized modification (1 or 2 years).

The window should be an oval-shaped hole.

Tim Hyatt volunteered to send the clutch info he acquires to SFI for distribution to the full committee. SFI would then coordinate R&D testing with the manufacturers.

The committee will then meet mid-year 2009 to review its findings. A possible location would be during the NHRA Norwalk race in June.

The committee had no other items to discuss regarding Spec 6.1.

Next the committee addressed Spec 6.2. It was pointed out that a 6.2 bellhousing is tested with a flywheel with ring gear, but in actual use, there is no ring gear installed. It was proposed to revise Spec 6.2 to use a test flywheel that has no ring gear. The committee voted and unanimously passed this proposal. The proposal will be sent to the SFI Board of Directors for final approval.

There were no other items to discuss regarding Spec 6.2.

The committee had no items to discuss regarding Spec 6.3.

With there being no further business, the meeting adjourned at1:35pm.

Respectfully submitted,
Jennifer Faye
Program Manager

That would be a great deal! I have talked to several on this issue, but never dreamed SFI would even hear it. I sure hope it happens. Changing counterweight without pulling the bellhousing would be a real treat!

My brother and I put a QuickTime bellhousing on our car this year and it is very nice. It is steel, but it is smaller, fits better and is 12lbs lighter than the Lakewoods that we had been running. I have some pics of it if any stick guys are interested. PM me or e mail. jimschaechter@earthlink.net

Re: SFI Scattersheild meeting
 

Why not a 5-year certification on a Scattershield with a window?

Re: SFI Scattersheild meeting
 

Jim, I am having trouble getting e-mail to you. Could you send some pictures of the bellhousing to me. Thanks Fastman68@aol.com

Re: SFI Scattersheild meeting
 

The problem at SFI is Arnie Kuhns...he needs to be replaced by some one with a lot of more knowledge and common sense.

Re: SFI Scattersheild meeting
 

Greg:
I agree.
Can anyone explain the logic behnd 1-2 year certs on S/SS scattershields?

" The spec should require a recertification life to prevent unauthorized modification (1 or 2 years)."

Re: SFI Scattersheild meeting
 

good for only two years if this is approved?

Re: SFI Scattersheild meeting
 

So would that make my scattershield I just purchased(without an adjustment hole) good for only two years if this is approved?

Re: SFI Scattersheild meeting
 

What they are saying is 6.1W would require re-cert sooner than the 6.1. W for "window"" bellhousing.

See www.quicktimeinc.com for their bellhousings. What Jim said was correct, nice, light bellhousing. More floor space too.

Re: SFI Scattersheild meeting
 

WOW...they even clain to "INCREASE HORSEPOWER" too....
Just like "PICKLED" heads and intakes I guess !!!

Re: SFI Scattersheild meeting
 

Some years ago, I challenged SFI on the 2 year requirement. I collected data from S/SS and Comp stick shift racers. Also, I took a Lakewood bellhousing, did extensive structural analysis and gave the data to NHRA.

After a telephone discussion with NHRA, they asked me to submit and talk to SFI. What a joke!!!
Spent 30 minutes with SFI's Arnie Kuhns and he could not come up with a single piece of factual or historical data on S/SS or Comp classes. The criteria SFI based their finding and requiremnt was from circle track and off-road racing vehicles for which they did not have a requirement for a SFI approved flywheel or clutch assembly in their rules. Many of these classes were still running OEM or Chinesium flywheels/clutches. Due to their failures, SFI applied the requirement as a general rule to all motorsports requirements.

NHRA has the authority to use the SFI requirements as a "Guideline" or "Suggestion" and extend the requirement as they deem appropriate for S/SS and Comp classes.

Re: SFI Scattersheild meeting
 

Just wondering if anyone has heard any new scuttlebutt on this...

Re: SFI Scattersheild meeting
 

This is stupid!

The shield is a hunk of metal and is not likely to fail just sitting there behind the engine.

It should be visually inspected on the OUTSIDE by the NHRA to look for obvious damage, rust and cracks.

It should only be inspected off the engine if it has contained a clutch explosion.
