FAQ Regarding Cobra Drivetrain Setups

[D-CEL]

Brent,

I must say, you are now carrying the QT company flag well.
“He has told me all of his bells will contain a flywheel explosion at 10000 rpm.”
well this is clearly not the case, two documented failures in one thread. One 460, one windsor
But he (Mr. Mc Combs) still hasnt answered the question. Was this part number tested by SFI and did it pass? The web site says it has, why isn’t it certified?
Unfortunately, your analogy doesn’t hold water or snakes. When you say “No I dropped the bag” you lay blame on the owner.
According to my conversations with him, it was installed with the supplied hardware in as delivered condition.
Lets rewrite your quip it to be accurate:
“The bag, while nice to look at and smaller than the other bags on the market was clearly incapable of containing even small snake let alone the very large and dangerous snake as claimed in all of the bag manufacturers questionable if not downright misleading advertising.”

Yea, that’s better

I will say this again: It’s not about the failure or that QT does not design and produce a good part. I have no doubt that they have thousands of happy customers.
I have no problem selling a part that doesn’t meet the spec.
Just clearly and accurately depict the differences and don’t mislead your customers.

“Its smaller, lighter, generally cooler n every respect, However it does not have the containment capability of the SFI 6.1 certified designs”

Why is it that the truth so scary? Failures happen, I see them everyday, use them to learn and improve.
It is blindingly obvious the there is a market for a housing with the ground clearance of the QT but incorporating lower half containment.
Build it, test it, and Ill buy one.

p.s.
I meant to comment on the 1” thick steel plate vs block.
So is the block at fault? Absolutely not.
The bell housing bolt bosses on engine blocks were never designed to absorb failure impact as seen in a flywheel/clutch explosion. They are meant to hold the transmission on, nothing more. That is obvious.
The reason for a block plate is to absorb and distribute the energy, while isolating it from the block, hence the name “block saver”
If the plate is too thin, wrong material or lacks sufficient bolts to spread the energy over the largest possible area, every block will fail. Big or small, Chevy or Ford the block will fail.
I offer this, If the system QT has designed can only pass when its bolted to a 1” steel plate, Its not much good is it…
