In addition to meeting the rigid requirements of professional race teams and production automotive manufacturers, Abrasive Flow Machining is an effective process for virtually every type of muscle car and high performance import including Mustangs, Corvettes, Porches, BMWs, Honda and Acura. This custom airflow tailoring process has demonstrated power increases that far exceed any hand finishing and porting process. By passing that abrasive putty-like compound through the internal passages of ordinary cast and machined parts, the process will control the shape and smoothness of areas inside the part that normally cannot be reached with ordinary machine tools. By lowering the turbulence within the flow passages, the engine will breathe more easily, and increases both the mass flow rate and entry velocity of the air drawn into the combustion chamber, providing a more complete and leaner fuel/air mixture and consequently, a more efficient and cleaner combustion. The Abrasive Flow Controlled Machining process is used on both fuel and air components, such as, inlet scoops, inlet ducts, intake manifolds, intake plenum chambers, cylinder heads, exhaust manifolds, turbochargers, superchargers, fuel injectors, fuel valves, etc. The media demonstrates properties of both a liquid and a solid.
While "at rest", the media exists in a fluid form. If
you held the material in your hand, it would most likely ooze to
the floor. How quickly this would happen depends on the particular
thickness of the material. It is this split personality that allows the Extrude Hone process to work so successfully. When the putty is put under pressure using the hydraulic Extrude Hone machines, it flows through the intake passages like a liquid, following the exact same path as the air-flow. The hydraulic pressure from the machines is transferred through the putty to the abrasive carbide material. This allows the putty to remove material from the adjoining areas uniformly like a solid. When the "Silly Putty" runs into an air-flow restriction it acts like a solid and removes the restriction. It's like having a miniature hand porter go in, find where the restrictions are and remove them. This is very useful when porting long runner intake manifolds.
A plastic, abrasive-laden polymer media is pushed through a part, such as an intake or exhaust manifold, clamped to the processing machine. The media, sands away unwanted material, stress risers and burrs from the internal passage ways creating a smooth, polished surface. For most applications, the flow of the abrasive media is extruded in the same direction as the normal flow of the engine’s fuel and exhaust gasses. The Abrasive Flow Machining process creates obstruction free passage ways that allow air, fuel, and gasses to pass more quickly through the engine components to maximize flow velocity. The result is an engine that produces a faster, cleaner burn and more power output. The process routinely delivers increases that can exceed 30 percent on aluminum intake manifolds and 25 percent on cylinder heads not to mention a cleaner burning, more fuel-efficient engine.
This immensely popular process is now refined to accommodate virtually every commercially available model of intake and exhaust manifold, engine heads, turbo impellers, housings and pumps, as well as two and four-stroke cylinders on automotive, marine, diesel, and motorcycle components. Polishing and smoothing any passage way that air, liquid or fuel flows. Today, several OEMs including Cadillac and Ford use the Extrude Hone AFM process as an effective method for lowering emissions as well as increasing engine performance on several of their top selling models. Diesel fuel injector manufacturers also rely heavily on this process to improve the performance and fuel efficiency on big rigs, motor homes, and off-road construction equipment.
The result is a dramatic flow increase that is related to flow velocity not flow volume. Major benefits are increased horsepower and torque, throughout the power band while reducing emissions and improving fuel economy at the same time!

airflow enhancement. The "Silly Putty" is impregnated
with small abrasive silicon carbide chips or beads that act as a
cutting agent in the putty. By forcing the abrasive putty back and
forth (sometimes in only one direction) through an intake manifold
or cylinder head port, material is removed from the inner walls.
This removal process improves airflow through the passage by approx.
15% according to EH. Extrude-honing is the best way to port a lower
intake manifold as its elaborate twisting shape makes die grinding
impossible. 
Though
the putty exists in a fluid form all the way to the ground, for
that split second that it contacts the surface, it changes to a
solid. | Home
