FDR and Timming Help for a 25.5
Looking for a little advice since never running a 25.5 motor before. Wondering what FDR and timing to start with on a track 95' X 48 with my 25.5'?
I currently run the 17.5 and 21.5 's with 52.5 timing and an FDR of around 4.7 on a track here at home of 82'X36', not too technical but a nice flow and they are FAST and coming off under 150 degrees. I see some of you are suggesting an FDR in the Mid 3.5's and a slightly lower timing. Maybe its a different field with the 25.5 motors and me not having experience with them specifically so could be these 25.5's don't agree with the way I set up the 17.5's and the 21.5's so asking for some help.
Thanks in advance......

Thanks fir the feedback guys, lots of wide gearing ranges to test.

Ran my 25.5 at 2.8 today with the timing just below the 50 mark. 65* ambient on a tight track and the motor was 95* with no fan.
