My RAM aluminum flywheel is SFI rated. I guess that is good, but I don't know specifically what it means  . |
In case you're still wondering...
"What Do the Letters "SFI" Stand For?
SFI was originally a foundation run by SEMA, the automotive aftermarket trade organization. The letters "SFI" stood for "SEMA Foundation, Inc." Although SFI is now completely independent from SEMA, the Foundation has retained the name SFI Foundation, Inc. but the "S" no longer means SEMA.
Who Uses SFI Standards?
Manufacturers of equipment are the primary users of SFI standards. Some standards are adopted as part of the rules of race sanctioning organizations. Ultimately, the consumer benefits from the program as it establishes recognized levels of performance or quality for a product.
How is the SFI Standards Program Funded?
Participating manufacturers pay for development and administration of these programs through licensing fees and/or unit charges. Also, interested associations have provided grants and donations.
How is a Standard Initiated?
The SFI Technical Committee initiates the specification process, typically at the request of the affected industry or race sanctioning body.
How is Participation Obtained?
SFI encourages industry-wide participation in the drafting of specifications. However, once a standard is enacted, participation by the manufacturer is strictly voluntary.
What About Enforcement?
Typically, there are policing provisions through contractual or licensing agreements whereby SFI may inspect the records and/or equipment of a manufacturer in order to ascertain that the product involved meets SFI Specs. Once a manufacturer has voluntarily committed to participating in the program, it must comply with the specifications in all respects.
How Are the Specs Used in Racing?
When adopted as part of the rules of a race sanctioning body, enforcement is entirely up to that organization. The manufacturer then provides the racer with product that is in compliance with the specs enforced by the sanctioning body.
