I see so much about the SP-57, 60, and 63 turbos and nothing about the SP-66, which I think might end up being real popular. I's very interested in seeing some concrete track numbers, info, and dyno results so that I can see how it is going to compare in power and spool to the SP-63. Last I heard Supratt96, said he was getting ready to put one on for the dyno and the track. Did I miss something? Anybody out there running a SP-66?
