Does a carburetor spacer add horsepower?

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.

Should I run 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 carburetor 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.

Will a bigger carb make more power?

How Does A Bigger Carb Give More Horsepower? A bigger carburetor has a bigger space that can help to increase horsepower by allowing more air and fuel to travel into the combustion chamber at once. More air and fuel in the combustion chamber means bigger combustion is generated. Thus, more horsepower.

Which is better single or dual plane intake?

If your vehicle is mostly street driven, go with a Dual Plane Intake Manifold. If you have a dedicated race engine that lives at high rpm or a modified, big-cubic-inch engine then a Single Plane Intake Manifold may be a better choice. Either way, you need to match components that work in the same rpm range.

Are spacers good?

Wheel spacers can be used to change wheel bolt patterns and to widen the offset of the wheel. All that being said, wheel spacers are a cost-effective way to keep the wheels you have (or adapt a different lug pattern wheel) while increasing your track width.

Should I use a carb spacer with EFI?

Yes, you can use a carburetor spacer with TBI. Holley tested this (LINK), and open spacers usually work best with EFI.

How much horsepower does a Edelbrock Performer intake add?

After you fix what’s limiting performance, an Edelbrock Performer intake can add as much as 10 HP.
