I run a X20 7.5 in my B44.2, love the motor. I have a 8.5 in my 2wd buggy and 7.5 in my Stadium Truck.
For the 6.5 I would suggest 16-18 tooth with stock spur. Start 16 and check temps, gear up or down as needed with motor temps.
My 7.5 is 21/81 and comes off about 115 after 8 minutes with light boost and stock timing. My track is indoor and has some tight sections.
