Does a carb spacer do anything?
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.
Does a carburetor spacer add power?
Yes, they will give you more horsepower. But carb spacers have another important function. They also act as insulators which keep engine heat away from your carburetor to ensure cooler incoming air and fuel.
What is a heat spacer?
The spacer serves to insulate the carb from CONTACT heat transferred from the intake (if it is phenolic) as well as smooth out turbulence out of the carb to the individual cylinders. The heat shield reflects RADIANT heat from the intake, lowering the temp. of the fuel in the bowls preventing percolation of the fuel.
Does a carb spacer add torque?
While open spacers add plenum volume, which can reduce low-end torque and extend the upper rpm range, a four-hole spacer will add low-end torque by increasing the air velocity. Of course, this is assuming the camshaft can help provide it. Our experience with carb spacers isn’t without proof either.
Should I run 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.
Do I need to run a carb spacer?
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. Intake manifold manufacturers aren’t stupid.
What does a 2 inch carb spacer do?
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.
How much difference does a carb spacer make?
How do I choose a carburetor spacer?
Spacer Materials There are four typical types of spacer material: wood, phenolic resin, polymer (plastic), and aluminum. Each has a different thermal conductivity (heat transfer) rating that tells you how well the material insulates against heat. The lower the rating number, the better the material insulates.
