silverM3... With the right tune pipe, proper engine breakin and gearing, the TZ-12 3P can run with any non-modified Italian motor day in and day out... And in most cases... beat them on any size track... Remember, a tune pipe can change an engines performance in a big way... One pipe can give a motor more low and midrange torque and power, while another can give you so so bottom end, but bolistic top-end power... Anyone buying a TZ will be very happy and should have no problems racing against any legal .12 motor on any size track...
