Not having any junkyards around here anymore i went to the Ford dealer and
bought mine. It takes a soild wack to trigger it when hand held. I have not
really wanted to wack the car to see what happens. I could take a rawhide
hammer to the frame rail and see what happens.

Always the one to try and be safe, I see in the 2009 rule book that inertial
switches for fuel cut off are going to be required for 2010. So I purchased
one from Pegasus racing thinking that they sell stuff used by the formula ford
cars and SCCA cars as well. Well it came yesterday. Kinda spendy for such a
small part. However, I am surprised at just how easy it is to trigger. If I
have it in my hand and just briskly wave that hand around, it will trigger.
AN dof course, it triggers when I hold it with one hand and bump with the
other. I am really thinking that this particular unit may trigger in just a
simple spin or near spin. Of course I guess I could mount it right on the CG
and just a rotation of the unit woudl occur. The insructions for sure say not
to mount it on a panel which can vibrate as that will trigger it.
My questions are manifold. Are there going to be, if anyone knows, any kind of
spec for these items? I would think that someting akin to an SFI spec is
needed here. If a simple piece of foam requires it, then someting that might
prevent a large fire should also need a spec as well. We have approved fire
extinguishers why wouldn't this also need some kind of at least generic
approval.
Next question, for you folk that have these already installed. How much of a
wiggle or impact did it or does it take to trigger yours? It may simply be
that it is working fine and that I can move it fast and hard enough to
trigger.
I have sent the company an email asking what kind of g levels or just motion
it would take to trigger it under normal or not normal circumstances. When I
get the answer, I'll post it.
Yes, I know that I could have gone to the junk yard and bought one. So exclude
any comments about that please. As the same questions apply...what are the
trigger levels....
comments?
