Your carb is an extremely important part of your set up. But how do you know if it’s right? With a chassis dyno you can know for sure. The graph shown is from a Super Late Model. From one run to the next, the only change was 2 jet sized to get the air/fuel curve a little leaner. The end result was about 10 horsepower and 10 lb-ft of torque. The gains were not just at the peak, but through almost the entire rpm band. This directly equates to more speed on track!
