i heard the same, that Piccos have great torque. I am curious to know exactly why this is? Is it a case of different timming, or is it something else?, for example the construction of the sleeve material or design? i always noticed that the Piccos have a thicker top ring section on the sleeve, i wonder if this is part of the extra torque. ie the sleeve doesn't expand as much at peak temps so the compression is higher and therefore the torque is better?
