What is an Edelbrock Air-Gap intake?

What is an Edelbrock Air-Gap intake?

Edelbrock Performer RPM Air-Gap intake manifolds incorporate race-winning technology that’s been used on Victor Series competition intakes for years. The open air space from the Air-Gap design separates the runners from the heat of the lifter-valley cover.

What is an Air-Gap intake?

The air-gap design features an open air space that separates the runners from the hot engine oil resulting in a cooler, denser charge for more power.

What is the difference between a single plane and dual plane intake manifold?

A dual-plane intake manifold has two separate plenums that each feed only four cylinders, while a single-plane intake manifold has a single, open plenum that feeds all eight cylinders. The smaller plenum found in a dual-plane intake, favors power production at a lower rpm range.

What is the difference between Edelbrock Performer and Performer RPM?

The Performer is designed for optimum performance in a lower rpm range than the Performer RPM. The RPM will deliver absolutely more horsepower but it will do so at high rpm’s. If you are preparing a race car for open track and expect to be operating at WOT a lot then the RPM is for you.

What does a high rise intake do?

High rise intakes are taller than low rise. High rise is a general term to describe an intake. There is no standard height where low rise intakes end and high rise intakes begin. High rise intakes are better at building horsepower in the upper RPM range and usually have a wider power band.

What’s better single or dual plane intake?

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.

How much horsepower does a high rise intake add?

One might expect the intake that had the highest average flow was best. In this instance, it was the second intake from the top. However, it showed a minimal gain in top end (about 3 hp) while costing twice that much in the 3,000- to 4,500- rpm range, which is used so much more often.

Does a high rise intake increase horsepower?

High rise intakes on the other hand are better at building horsepower in the upper RPM range and typically have larger and longer intake runners. The power band of a high rise usually starts around 2700 to 3000 rpms and they can be capable of making power all the way through 7000 to even 8000 rpms.

Which is the best Edelbrock air gap manifold?

An Edelbrock Performer is an ideal choice for muscle cars, hot rods, restomods, passenger cars, custom trucks, 4x4s and RVs. Performer Air-Gap manifolds offer the same performance-proven qualities of the Performer Series but with the addition of Edelbrock’s patented Air-Gap design.

How to check the height of an Edelbrock intake manifold?

To ensure adequate hood clearance of your Edelbrock Intake Manifold, check the height of your stock manifold and compare the “A” and “B” measurements against those of the Edelbrock manifold prior to purchase. The heights of all Edelbrock manifolds can bee seen on the Manifold Reference Dimensions page.

What are the Edelbrock performance power package systems?

They include Performer RPM or RPM Air-Gap intake manifold, Performer RPM cylinder heads, pushrods, hydraulic cam and lifters, timing chain (in most cases), complete bolt kits and an Edelbrock gasket set. Select RPM Top End Kits are available with EnduraShine finish.

What’s the difference between performer and air gap manifolds?

Performer Air-Gap manifolds offer the same performance-proven qualities of the Performer Series but with the addition of Edelbrock’s patented Air-Gap design. The Air-Gap series features an open air space that separates the runners from engine heat resulting in a cooler, denser charge for more power.
