.Having some fun out on a Easter Sunday tuning the 2 speed trans, chasing down cars, burning tires, and trying out my racing locking differential. I like the 29.5 for the torque, but my heart loves the 27.2 OBR for the added rpms. I don't know how long I'll keep it gas, but a electric conversion would do wonders. Top Speeds 61.4 with the body off and 58.5 with it on. I probably could squeeze a little more, but may try next weekend
