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.

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.
