Photoshop :: Speed Blur Effect

I have a technical question I wonder if anyone on here can answer. I am far from a Photoshop newbie having been using it from version three, but rarely get the chance these day to fathom all the new widgets on new versions.

For many years I have always hoped that Adobe would include a filter for a speed blur. I know it does a motion blur, but what I want is a blur that show the direction of the apparently moving object. I am working on a project where I have animated a chilli on the companies web site where it flies around. I want to give the impression of movement with the blur coming from the tail of the chilli for a leaflet.

Here's the image I am working with, though it looks a bit crap here as it's cmyk.
