I have a 2004 FTD with a 225 Optimax that is set up @ 2.5" below the pad. Currently I am running 71 GPS @ 5560rpm, with a full load and one person with a small hub 26p Trophy. I tried a 25p large hub Tempest and I was all over the rev limiter and speed droped to 65mph. What is my next move? Should I try the 25p Trophy or the 26p Tempest. What is the performance difference between a large hub prop and a small hub prop if they are the same brand and pitch?
