Extrude Hone AFM Porting of a 1993 Mustang Cobra Intake Manifold

I stopped by Extrude Hone to take a look at their AFM porting process and to get my 1993 Mustang Cobra / GT40 intake manifold ported. Extrude Hone created a process called Abrasive Flow Machining, or AFM. A hydraulic machine pushes the AFM "putty" through metal parts, such a cylinder heads or intake manifolds, which ports and polishes the inside. The process is great for porting an intake manifold that would otherwise have to be cut in half and ported by hand since you can't normally reach all the way through the runners. The blue putty is in raw form. The light grey ball is the putty with some silicon carbide mixed in. The silicone carbide is the abrasive material that cuts through the metal part. The last blob is the putty that's been pushed through an intake manifold and contains the metal that was shaved off. It can be recycled and used many times. In this short video, you'll see the Extrude Hone process on a four runner manifold and then a Mustang Cobra manifold. Each cycle of pushing the AFM putty through the manifold takes about 15 seconds and then it takes about 280 cycles to port the Cobra intake. As you will see at the end of the video, the manifold flows around 100 more cfm per runner, which is a huge increase. More importantly, all 8 runners are flow matched now. Runners 1 and 5 flow poorly from the factory, but it's all fixed now. You can follow the build of this 1993 Mustang Cobra at   / motorator
