For reference, the higher you go in number in Cam, the more low end torque you get. The lower the number, the more top end. Example: This A9 is as low as we would suggest you go and it will net you more top speed. An A10 Cam would be for more mid range torque and An A11 Cam is as high as we would suggest and has the best low end take off speed but not as much top speed and, it's also hard on your engine. We do not suggest going this high unless you're circuit racing and don't mind replacing your piston and rings every season.
