Bellhousing

I see in the pictures there is a plate between the bellhousing and engine, however the only bolts appear to be threaded into the block.

My Lakewood has additional bolts and nuts, spaced between the bolts threaded into the block, clamping the engine plate and bellhousing. These help contain the flywheel/clutch pieces between the plate and bellhousing if the block breaks.

This makes me think the bellhousing on the dyno was not SFI approved. I was surprised there was no mention of the bellhousing in the thread.

There is a difference between "SFI 6.1 rated" and "passed SFI testing."

To comply with SFI 6.1 rules, the bellhousing must be bolted along the bottom perimeter.

To pass SFI testing, the bellhousing must only contain a flywheel explosion at 10000 rpm.

I don't work for Quicktime. If you want proof of the tests, then please ask Quicktime (now part of the Prestolite company). As for myself, that's the only proof that I need. If Quicktime says that it passed SFI testing, then I have to take that at face value.

However, I do not blame the bellhousing for the incident that occurred to this guy's Boss 557...

I suppose we could recreate the incident with an SFI 6.1 bellhousing. Anyone have a Boss 557 that they would donate for the testing?

I just got off the phone with Quicktime (now owned by Mr. Gasket).
I spoke with a rep who stated he has industry experience with Bellhousing testing and certification. Additionally stated he had been present during testing in the past.
I told him who I was and gave him a brief description of the issue being discussed here.
I am paraphrasing a little, but this was the conversation
Jason: I’m looking at your website, specifically part # RM-8010. It says
“has passed all SFI testing” Please tell me what that means.
QT: It means that It can pass if you use a block plate and the containment bolts. SFI certification is very expensive so we offer the customer a cheaper alternative. It does not come with a block plate or bolts. But if you use a block plate and the bolts, it will pass. The metal, the shape has been tested and passed.
Jason: hmm, the website clearly shows a block plate included, but this specific part number does not have the lip or holes for the containment bolts
QT:. what part number is it?
Jason: RM-8010
QT: Hold on im looking..
(While he looked I brought up the video and spoke of the parameters of the failure, his tone changed, He asked me to forward the link to him, I did)

Jason: Let me be very specific: Has this part number, this configuration, without the lower containment bolts been tested and passed by SFI?

QT: No, without the lower containment bolts, it will not pass the test, it cannot contain the explosion, pieces will get out

Jason: I take issue when your web site states that it passes the test, insinuating that it offers the same level of protection. In speaking with the owner of the motor in the video, he believed that the housing he purchased was the same design as the SFI 6.1 housing, but not certified. It isn’t.
QT: I see that, I can tell you, we are in the process of taking over the quicktime website and reviewing the content, I will forward your comments, thank you for making us aware of it.
Then I called and spoke with Jennifer Faye, Program manager for SFI.
She was kind enough to send me a copy of SFI 6.1 so I could be clear on the requirements. She said that she would investigate.
