When it comes to cars what does it mean to port/polish somthing like the heads?

Question:


Answers:

Car problem. Ideas?

Porting and polishing the heads of a car means to increase the air flow of the heads. Porting is the process of changing or enlarging the "tunnel" in which air flows into and out of the engines cylinder. Porting is usually done by grinding material away to "open" ports up, hopefully causing more airflow. Polishing is simply smoothing or cleaning these ports or tunnels so there are no obstructions of airflow. More airflow in and out of an engine equals more power.

Anyone own an oldsmobile bravada and have mechanics knowledge?

Polishing is making the surface smooth and glassy - offers less resistance. if there is less turbulance and resistance, it's easier to move through.

it's like aerodynamics... the smoother the shape of the car, the easier it moves through the air.

It to improve performance. They polish the openings in the intake manifold ports then run a flow test on them and make corrections by fine polishing. Porting is more of the same idea. Lots of guys try to do it using a dremel or something but your just guessing without some sort of flow test. The idea is to improve the flow of air and or air fuel into the cylinders.

It means that the intake and exhust ports are inlarged and smooth out to remove the roughness of casting in the ports Thisprocedure let s more air flow with less restriction in and out of the combustion chamber making extra HP.When they smooth out the port they usually look like mirrors in there

How much does it cost to restore a car?

Porting involves grinding on the ports to make the air passages larger so more air can flow in or out. Polishing simply smoothes out imperfections to further increase air flow. An engine is nothing more than an air pump... the more air you can get in (and out), the more power it will make. Porting and polishing are two of many methods used to increase air flow.

Porting and Polishing (P&P) is the removing of material from the intake/exhaust ports as well as the combustion chambers for the reason of improving flow both in AND out of the combustion chambers. Stock heads are made from cast aluminum and if you look at the intake and exhaust ports, they are a very rough and have lots of sharp edges.

Will my corvette run with the crank and cam timing incorrect?

It means the cylinder heads have machine work done to them that increases performance. Porting and polishing improve fuel ionization and exhaust flow.
