13.5 SEDAN GEARING

Hello,I was looking for a good starting point to gear a 13.5 in the foam tire sedan class? I will be running a TRF 415 and the track size is like 60x90.64p gears will be used.Thanks

anything between a 47 - 54mm roll out
I have run a highest of 53.6 witha SP GT 2.0 and SP 17.5 with motor just over 60 deg/c
Start conservatively geared and keep gearing up till motor temps around 65 deg/c after 5 mins and you can gauge from lap times and performance feel.
Always nice to have a few cars to run against.
