For a daily driver, by reducing the 'normal' temperature from ~110C to ~90C MHD has taken a lot of the 'need' away from getting an upgraded radiator.

It means there's a now reasonable buffer between 'normal operating temperature' (90C) and 'damn, that water's hot' (120C).

But if you're driving full noise around a hot track in a car pushing 30psi, your initial water temperature matters a lot less and your ability to shed heat in real time matters a lot more.

So, for a daily driver, it's probably no longer worth it. For a track monster, upgrade your radiator.
