Back with more insights, it's Casey from the Going Bracket Racing Podcast, and today, we're delving into a crucial aspect of Proform's alcohol series carburetor - the metering blocks and their impact on your air-fuel curve.
(06:14) These metering blocks handle the critical air side of the equation. It's all about air, with high-speed air bleeds feeding it in. Then, it travels down to the booster, where the magic happens. Here's where the tuning magic comes into play.
By adjusting your high-speed air bleeds, you can control your entire fuel curve. It's like a symphony, moving the entire curve up or down. But wait, there's more! The top two emulsions are more sensitive, fine-tuning your low-end power, while the bottom two emulsions focus on the high-end power.
Why? Well, it's all about the Venturi effect and how it naturally pulls more fuel at higher RPMs. These metering blocks are a game-changer in modern carburetor technology.
Stay tuned as we continue to explore this fascinating subject. And if you're enjoying this, don't forget to subscribe to our podcast. We're here to help you master your racing setup, come rain or shine!
