What this leaves out is the fact that the lightweight flywheels sold by Dinan increase resonance as well. As a matter of fact, ERT's study showed that there was a larger increase in resonance from a lightweight flywheel then from a pulley which sounds reasonable since there is a much larger reduction in mass. So while Dinan is damning the pulley he is also damning his own lightweight flywheel.
The arguement about underdriving itself is a valid point, but cannot really be properly addressed without looking at numbers. The theory is sound, but Dinan is hardly quantitative. "Underdriving too much can ruin an engine" is a true statement, but so is "Drinking too much water can kill a person". Without any quantitative data these are both useless statements.
Anyone else have any thoughts on this?
