x-ray gearing
 

i have an x-ray t2 i just picked up and am having trouble with gearing. i'm running on blacktop. i bought a 32t pinion and an 81t spur(64 pitch). gears don't mesh at all. i'm running a tekin 13.5. i'm new to touring car and would appreciate any info.

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.
