Extrude Hone’s Abrasive Flow Machining (AFM) process is recognized worldwide for its ability to increase horsepower, thrust, torque and airflow on all types of internal combustion engines. Whether you’re running a two-stroker, a fuel-injected eight banger, or a jet turbine with full afterburners, we’ll help you make it go faster, further and cleaner.
Extrude Hone developed the Abrasive Flow Machining process more than twenty-five years ago to enhance the performance of automotive racing engines. The demand for this process increased rapidly among car and motorcycle owners and soon caught the attention of professional racing teams worldwide. Today it ranks among the most sought after performance improvement available to car and motorcycle enthusiasts. There also is a growing interest among personal watercraft and high-performance truck owners as well.
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.
How The Process Works 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.
Results
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.
Flexibility
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.
