I guess the engineers put that red line there for a reason.
After we modified the engine, tho', nothing we did fazed it.
Great stuff, Bozola. The XT/TT engines were famous for grenading when piston speed exceeded 4,000 fpm. Glad to hear you discovered a way around it. Was there ever a retail source for the base plate or was that a one-off?
