Just returned from Grattan Road race where I watched a Maxter,TM,and a Honda(factory prep motors, major race shop motors to home built motors)race side by side for a half hour with any of the motors capable of leading or winning at any time. Some of the best racing you could watch not knowing who would win till the final lap draft set up. Then all three motors crossing the finish line side by side thousandth of a seconds apart. Damn that was fun to watch.
Pick your motor and start the trash talk now. (My motor is better than yours)
Not all drivers are (created) equal…:). Have a top level (fast and consistent) driver drive these various engines and he will show/tell you they are quite different and one is undoubtedly better and faster than the other.
