	Manifold vacuum - Wikipedia, the free encyclopedia
		Manifold vacuum is an effect of choked flow through a throttle in the intake manifold of an engine.
		Manifold vacuum should not be confused with venturi vacuum, which is an effect that is exploited in carburetors to achieve a fixed mix ratio between fuel and air.
		The manifold is connected directly to the air intake and the only suction created is that caused by the descending piston with no venturi to increase it, and the engine power is controlled by varying the amount of fuel that is injected into the cylinder by a fuel injection system.

	Manifold (automotive engineering) - Wikipedia, the free encyclopedia
		In automotive engineering, an intake manifold or inlet manifold is a part of an engine that supplies the fuel/air mixture to the cylinders.
		The intake manifold is usually made of aluminium and located between the carburetor and the cylinder head.
		Exhaust manifolds are generally and traditionally simple cast iron units which collect engine exhaust and deliver it to the exhaust pipe.

	Intake Manifold - Partstrain.com
		An intake manifold is a system of passages that carry out the fuel/air mixture from the carburetor to the intake valves of the engine.
		The L-head engine’s manifold is mounted to the side of the block and the I-head manifold is mounted to the cylinder head.
		Manifolds in modern engines are designed like this so that the amount of fuel condensing on the intake manifold walls is reduced to a minimum.

	Intake Manifold Heat for Carbureted Engines (Site not responding. Last check: 2007-10-19)
		This device is usually a valve or flapper that diverts exhaust gas to a hot spot in the intake manifold underneath the carburetor.
		To get the utmost performance from a race car, the intake manifold needs to be as cold as possible but these cars usually don't run well year-round on the street.
		At slower speeds, the use of manifold heat becomes essential to ensure that the fuel is vaporized.

	Intake Manifold Comments
		This manifold type is typically a lower, lighter, and simpler casting, cheaper to make, and giving better hood clearance, as the runners leading from the carburetor to the intake ports are all at the same height.
		This manifold type is typically a heavy and complex casting, as the runners leading from the carburetor to the intake ports of adjoining cylinder pairs are at different heights.
		If the intake manifold is very small (“IR” type, with minimal internal volume), the effect of a change in combustion chamber volume will be much greater than if a tunnel ram manifold is used (where the plenum volume is typically larger than the cylinder volume).

	Intake Manifold
		The one-piece manifold, with it's soft copper gasket at the heads, is probably at the limits of it's capacity to stretch with this engine movement on the 1500 (it runs colder than the engine remember, so doesn't expand as much), and with the greater heat of the 1600, they needed to alter the design.
		I found that by removing the left tp "corner" manifold piece and lifting the fan assembly with generator attached I could finangle the new manifold centre section in.
		When it's in the car, the bolts for that piece are almost impossible to reach (socket with 1foot extension bar for the front nut and an open-end spanner for the rear bolt, turning it 1/12th turn at a time and flipping the spanner over each 1/12th (the heads are angled 1/6th turn).

	The Subaru Intake Manifold (Site not responding. Last check: 2007-10-19)
		In the era before fuel injection, gasoline was mixed with air in the carburetor, and the resulting air/fuel mixture was delivered to the engine’s cylinders by the intake manifold.
		Today the fuel injection system delivers gasoline much closer to the cylinder – at the base of the intake manifold next to the intake valves of the cylinder head –; where it mixes with air from the intake manifold to become an extremely precise mixture of air and fuel.
		The intake manifold of the naturally aspirated (non-turbocharged) Subaru horizontally opposed engine is positioned on the upper part of the engine.

	428 Cobra Jet Intake Manifold Identification
		This intake manifold, like all FE intake manifolds, is a "wet" (coolant flows through it) intake that extends under the valve covers when installed.
		All 1969 and 1970 CJs have a studded bolt in the third mounting hole on the driver's side of the intake that was used to mount a bracker for the shaker hood scoop.
		The -A manifold shown here also has taller ports than a standard -C manifold but it is possible that this manifold was modified after it left the factory.

	Manifold Mounting
		This is the area on the underside of the intake manifold where it connects to the exhaust manifold.
		It is always a good idea to align the altered rear manifold section with the intake manifold and then have the assembled pair surfaced ground flat.
		Install the new gasket and manifolds using all the factory spanner washers (the 1970 and later "thick ones" are the best) and be sure to use the brass washers and castle nuts on each top-end stud.

		The manifold flanges are cut from a stock steel VW dual port manifold.

	1952 Buick Intake Manifold
		When working on intake and exhaust manifolds it must be understood that both manifolds must be attached to the valve body and to the cylinder head in such manner that slippage can take place at the joints to compensate for differences in rate of expansion and contraction of the several parts due to heat.
		The individual intake manifold gaskets are centered and the branches of the intake manifold are aligned with the intake prots in cylinder head by pilot rings installed at each joint.
		When a new manifold is installed, however, coat the joint surfaces with a thin fluid mixture of graphite and oil.

	Intake Manifold Machining
		A separate intake manifold measuring system consisting of a jig set and calipers determines the proper width to suit each engine.
		An Intake Manifold Resurfacing Fixture can be configured as a rollover fixture to recut the head side of a sealing surface, then hold the head while being machined for screw in studs and guide plates in one set up.
		It can be implemented when the manifold is still in the fixture so a job can be checked at a midpoint to assure a good fit, or after machining for quality control.

	Dodge Intake Manifold - Partstrain.com
		Simply put, the task that intake manifold does is to take the air as it gets in the engine and transport it via intake passages into the runner ports which is positioned in the cylinder heads.
		In single plane intake manifold, the runners usually possess one turn and are relatively short compared to the runners in dual-plane manifolds.
		Majority of the high-performance manifolds in the industry are made from cast aluminum or sheetmetal.

	Fuel-Air-Spark Technologies - LS1 Intake Manifold — Popular Hot Rodding
		To truly find benefit in an aftermarket intake manifold design, it would have to be a composite part like the OEM piece, in addition to having a better design than the one crafted using all the resources of General Motors.
		The need for a multi-piece intake manifold (for porting access) combined with established minimal material thickness, consistency and quality concerns for mass production, and cost controls to ensure the product would be marketable all figured into the plan.
		The OE manifold is tested to 80 psi, but since we haven't tested our parts in that manner as yet, we can't really say ours will pass that specification.
