Certified? Not in a "homebuilt" group! 
True, but you hear little talk of non-aviation products and techniques even
in the Experimental catagory.
However, that said, I think you are right...reliability is a relatively
unknown word in racing engine circles I suspect...
Oh not at all. Any of the endurance type racing, circle track, road and
off-road racers are extremely concerned with reliability. The drag racers
are about the only ones that care little about endurance.
I'm still waiting for the space shuttles to be reitred so I's can get one
of their engines as surplus and bolt it on my Corben :O
