H22, F20b and H23VTEC timing belt walk
There's been so much talk about belt walk... here's some info.
We tested deflection on a brand new OEM idler pulley and measured it as tension was applied to a belt. There's a point that deflection stops, but the main point is that if too much tension is applied, the belt might walk.
As everyone knows, aggressive cams require more tension than stock or mild cams to avoid a floppy belt. The timing belt on the Outlaw car always hung off the cam gear a bit but it never bothered me. Anyway, here's the video. Enjoy and discuss.

I've seen rubber grommets behind the pivot bolt (14513-RCA-A01) on some engines, so that may allow even more play & more walk for some people.
