Don't do it! Here is what businesscycles has to say:
Caveat emptor: The Model V and ESH shown above are the only two Izumi chain models that are described in Izumi literature as being designed for track racing. Be advised that Izumi's "Eco" models are not track chains, despite erroneous claims you may occasionally read elsewhere (one website that listed them as such has since closed down, so I see them on ebay now mostly). The standard black Eco model is described in Izumi literature as for "baby carriages and . . . minibikes" (they don't mean the motor-driven kind). The variations of the Eco chain that are plated in a tacky gold or silver finish (the plating adds some corrosion resistance over the plain black model, but they're otherwise the same as the black one). Just because a chain is 1/8", doesn't make it a "track chain".
