We don't like to say that lightweight pullies "make" horsepower because they really don't. They do FIND lost horsepower though. Typically we've seen gains of around 10-12 HP on an underdrive pulley and a little less on a lightweight pulley.

This is news to me but what you're describing doesn't surprise me. With the new technologies they're constantly developing and the new materials being produced every day I truly believe that anything is possible.
Like you pointed out, I have a hard time imagining that it could be produce in a cost effective way but could you imagine how much higher you could rev an engine with lighter internals. It'd be pretty awesome to learn more about this stuff. Sounds too exotic to be in most production cars for awhile though.

I have to be honest. I am HORRIBLE at figuring out acronym's. What does SRM mean?
