I have said this many times before, if you had seen what happened, and what was left of a carbon fiber shield from a tranny that blew up in Eddyville in '13, you wouldn't even think of anything fiber. He almost lost a foot! That shield did NOTHING. Let me repeat that, it did nothing.
The way every body tries to fit a trans blanket, they don't work either. The trick is to put it over the trans, and wrap the ends around the torsion bars. You may need one simple brace to keep it off the headers on the driver side.
Think about this, at the track, I bet flywheels have killed more people than you'd would ever care to hear about. And some of those were in the stands.
Best of luck to you.
You dont want a blanket tight... you want them to
stretch and absorb the energy... the C/F shields that
are SFI approved are there for a reason... the trans
itself helps slow the energy then the shield helps it
even more.. and they arent thick... you want things to
stretch to eat up the energy
EDIT
On a 727 if you break the sprag anything over 6200 rpm
will blow the drum.... based on the 2.2 times faster than
the engine rpm and based on testing that 13,000 rpm will
rip it apart.. and we know MOST people turn more than 6200
rpm.... but if you dont do stupid stuff you wont blow the
drum.. NEVER get out of it and get back on it if the sprag
is broke.. that extra distance will roll over the ramps...
if you get out of it SHIFT... low is when the sprag is engaged
granted in this post its a manual trans
