What FDR are you trying to achieve? There is more than one way to get the number. Tried Gearchart (.com) ?

The xray t2 line has a 1.7 internal unless its a t2'009 which had the option for bigger pulleys to achieve a 1.9 internal. You should be geared at around a 5.0 FDR which is a 108/36 or 37t setup with the 1.7 internal ratio. Hope this helps. Also make sure you have a fan on your motor at all times. You may be able to gear up or down depending on motor temps. Also are you running NO TIMING class or BOOSTED?

I don't know on a T2, but I'm pretty sure a 32/81 would not fit on a T3; the motor would contact the top plate well before the gears mesh. You may want a bigger spur and pinion so you can move the motor forward. Again though, I'm not too familiar with the T2.
