20.19 rollout Jeff could probably tell you if you need to gear up or not. I would say you are pretty close. Maybe go up a tooth since the track is pretty fast now. The mod motor is going to be harder to drive than a 19 and will only be faster if you keep the same tight line.

Cool, thanks Chris. I would love to run mod again but this motor is not fast enough. My 8t kr is insanely fast but can only last 4.5 min even with me using ib3800.

The 9 should be fast enough. Your not going to keep up with quincy no matter what motor you put in the car....no offense. I ran a 9 when I went to practice and was running 10.7's with rubber tires so you should be able to get to the low 10's with foam and a 9 turn which is what everyone else was getting.
