I have a 03 CC DS gas cart, lifted, w/10x22. I do a lot of shooting sports and when you have 4 grown men on the cart, well anything other than a flat surface, is a challenge. I hear a lot about getting more torque or more top end speed, but not both. Can you get more torque and more speed without adding a big V-twin? In the magazines, i see adds for power adder kits, springs, key starts and the like. Are these the answer? I see talk about rev limiters & governors, is this the answer? I need help weighing through all of this.
