Tapered plenum

Our temporary duct plugs are designed for the interim sealing or standard duct, bell-ends and terminators from the damaging and expensive effects of weather, jobsite debris and animal incursion. Available in 11 sizes ranging from one-hal to six inches, the Poly-Plug is molded from the highest grades of virgin Low Density Polyethylene LDPEa tough, high-impact and chemically inert resin that has near-zero moisture absorptions properties.

LDPE is resistant to ultraviolet light and ozone and is capable of withstanding extreme fluctuations in temperature. While seemingly simple in concept, the Poly Pull Plug has many design features making it an effective, efficient and economical means for the sealing of your conduit lines. A long-run tapered design allows for easy and quick insertion into your empty duct while a concentric set of scalloped ridges on the outside wall of the plug ensure a tight seal and prevent accidental dislodging of the plug.

All Poly-Plugs come with a molded-in rope tie for securing excess line within conduit. Tapered Plug. Duct Plugs.In the extended plenum system see Figurea large rectangular duct extends straight out from the furnace plenum hence the term extended plenum and generally in a straight line down the center of the basement, attic, or ceiling. Round or rectangular supply ducts extend as branches from the plenum extension to the warm- air supply outlets.

The large extension to the plenum permits a better airflow rate with reduced resistance because of its large duct diameter. The branching ducts are usually located between joists and can be easily covered with a ceiling. Crawl-Space Plenum Systems It is possible to incorporate the entire crawl space into a heating system if the crawl-space walls are tight and well insulated.

The heated air is forced down into the crawl space and enters the rooms through perimeter outlets, usually located beneath windows. This type of duct arrangement may be referred to as a crawl- space plenum system and represents a modification of the extended plenum system.

Because the entire crawl space is filled with warm air, this system provides relatively uniform temperatures through- out the structure. Duct Materials Ducts are manufactured from a variety of different materials.

The material selected will depend on the use for which it is intended. It is very important that the duct material be taken into consideration when designing a duct system because not every material is suitable for all conditions in which ducts are used.

Plai n steel and galvanize d sheet steel ducts are available in thick- nesses ranging from 0. Ducts manufactured from this material are preferred for use in warm-air gravity and forced-circulation warm-air heating systems. Table indicates the thicknesses, gauges, and weights in which plain steel and galvanized sheet steel ducts are available. Aluminu m ducts are available in thicknesses ranging from 0. Although aluminum ducts are lighter than steel ones, they generally cost more.

Aluminum ducts are frequently used in duct systems located on the outside of buildings. Copper ducts are available in sizes and gauges matching the aluminum ones and are frequently used in outside ductwork. Round glass-fiber ducts can be purchased in a number of different sizes ranging up to 14 inches in diameter with duct walls up to 1 inch in thickness. Square or rectangular glass-fiber ducts can also be made from flat glass-fiber board.

Because of their composition, glass-fiber ducts dampen sound. Pape r -fibe r ducts are laid in concrete and used in warm-air heating systems. They are accordingly not recommended for use in attics, basements, or other exposed areas. V itrifie d clay tile ducts represent another duct material suitable for installation under a concrete slab.

tapered plenum

The IPD Plenum optimizes the intake system and when coupled with a larger throttle body, helps your engine breath better. The revolutionary and patented design of the IPD Porsche Plenums improve intake air flow by replacing the factory plastic "T" style design with a more efficient, cast aluminum "Y" design.

The IPD Plenums distribute the air flow more effectively by using a true merge collector and reducing pressure drop at the throttle body inlet. This superior and proven design ultimately results in considerably power gains throughout the horsepower and torque curves. Bottom line, the "Y" design delivers increased power and drivability.

Any pressure drop in the intake tract will serve to either back pressure the turbocharger in a forced induction application or to choke intake flow in a naturally aspirated engine. Both scenarios limit the performance potential of the engine. They have been tested, challenged and proven over and over again to deliver the power gains IPD claims. The countless hours we invest testing and tuning each Plenum design, ensures you are getting the highest quality and best performing Porsche performance product on the market.

Tech Feature: Custom Racing Intake Manifolds

Related Projects. Hi all, I have a question regarding intake manifold runner taper.

CFD Intake Manifold - Velocity Vectors

I have read somewhere, don't remember where, that adding a taper to an intake runner has the effect of shortening the runner. Is this correct?Editor's Note: As inanimate as intake manifolds may appear, they provide a path to both major and minor on-track power gains. Selection is one thing; "tuning" them to specific applications is a blend of skill and technology.

This story goes right to the heart of the second. It is appropriate that the intake manifold is mounted on top of the engine. After valve events have been selected, the intake is the primary tuning device for a four-stroke spark ignition engine, just as the expansion chamber is for a two-stroke.

Tuning becomes the manifold's second function. This is a critical factor in engine tuning because the mixture can only be leaned to the point where the leanest cylinder is at its operational limit. With individual runner IR induction systems and electronic fuel injection, the variation can be tuned to less than 0.

Cornering g-forces can have significant effect on the mixture distribution. All four carburetor main jets were identical. The data shows a variation from When tested on the dynamometer, this manifold showed a 2. As you might expect, the data shows the impact of the g-forces making the right bank richer than the left. Obviously, this effect will be more pronounced on tracks with high cornering loads and can be minimized by stagger-jetting the carburetor. This example was selected because it clearly demonstrates the point.

Not all manifolds are affected this severely. Another method of adjusting distribution is to move or bend the carburetor booster relative to the throat in which it's installed. Exercise extreme care when attempting to "bend" boosters.

It is also possible to place small "tabs" or "protrusions" on booster bodies to redirect airflow in the throat and alter post-carburetor flow direction.

IPD Plenums

Carburetor spacers may also have an impact on distribution see section discussing spacers. Often a four-hole or combination four-hole and open spacer will improve cylinder-to-cylinder distribution. Reading spark plugs may not be accurate enough for this type of development. The floor of the runner is usually the most sensitive area.

tapered plenum

Adjusting the runner opening so that it "sees" more of the plenum will generally make that cylinder richer. Often the center cylinders shroud the end cylinders in a V-type engine.

Careful unshrouding of the end cylinders can richen a lean-running cylinder. Manifold Selection Typically, the selection of manifold configuration is limited for circle track applications.

The choices are single-plane or dual-plane. Usually, engine operation speed determines the manifold configuration. If the power peak of the engine is below 6, rpm, then a dual-plane is most probably the manifold of choice. As the power peak moves significantly above 6, rpm, then the choice moves to a single-plane. The choice becomes more complicated when the engine's operation speed is somewhere in between.

In this case, there is no clear answer, so testing will tell the tale. If well developed, a dual-plane can be more responsive and may be the driver's choice. But regardless of which design or brand chosen or changes made, there are some essentials to keep in mind.

Intake manifolds don't flow in only one direction. There are times, depending upon engine speed and load, when pulses are directed back toward the carburetor or air inlet point. Technically, this describes bi-directional, unsteady state flow.
