Abrasive Flow Machining - The Art of Airflow
TurboKraft defines performance history with the use of AFM in the Porsche Industry.

Extrude Hone is  process of Abrasive Flow Machining (AFM).  This operation 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, using this process can help you make it go faster, further and cleaner.

Honing Your Engine's Horsepower Skills
What if you could increase your engine's horsepower and gas mileage while simultaneously reducing its emissions? What if you could do all of these things without adding a single piece of hardware to your engine? No moth balls in the gas tank or propellers in the intake; instead, we're talking about improving what's already under your deck lid.

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.

Get 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.
