Started a thread over in Rotary Performance, but haven't gotten much response so decided to try over here.

Freelance motorsports has their own coolant Seals. They look good on paper, but I can't find any reports of people's experience with them. Has anyone here run them? I'm doing this for reliability , not cost savings. It gets very hot where I live and I'm about to install a FMIC, so I want as much insurance from an accidental overheat as possible.

Really, it's a crap shoot with newer and untested products (untested by consumers). That said, it's hard to mess up a seal if the correct measurements are taken and materials used..

FWIW, I run Pineapple Racing's HD water seals in my peripheral port (which produces plenty of heat and fireballs)
