My 10% underdrive crank pulley came to me in 2008 and has been great for me however the one question I do have is whether or not you have a pulley that can handle 7-8k rpm operation without coming apart? Right now my research and past experience by another member is that once you really get into the more extreme rpm range you are pretty much going to have to use a stock pulley because these "upgraded" pulleys cannot handle the stresses at that level. Thoughts?
