Do you need a carb spacer?
Carb spacers only do one thing, increase the size of the plenum area of the intake manifold. Larger plenums = higher RPM power curves (less low RPM torque). Unless you are operating at or above 6,000 – 8,000 RPM and are using a single plane intake manifold, you “shouldn’t” need a carb spacer.
What are the benefits of a carb spacer?
A carb spacer increases the distance between the intake manifold and the bottom of the carburetor, which reduces the velocity of the intake charge. A four-hole spacer helps to direct the air-fuel mixture, making the streams more efficient. It also assists in preventing reversion from the pressure pulses.
What is the purpose of a carb spacer?
Spacers are said to improve air/fuel vaporization through and out of the carburetor. Anytime the air/fuel charge has to turn sharply coming off the carb, it increases the chance of separating the fuel from the air.
What’s better single or dual plane intake manifold?
Single-plane manifolds have a single intake opening into the plenum and feeds all 8 cylinders directly. The larger plenum area is less restrictive and supports a higher power range than a comparable dual-plane manifold, which has a wider power range and works better at low rpm.
