I had the March set and had the same problem that Rick talked about. The easy fix was to trash March's tiny crank pulley and and to install a single groove OEM 6 3/4" diameter pulley. I'm over-driving the waterpump by around 15% now and don't have anymore cooling issues, thanks to the pulley change and other modifications.

The March set is designed for a more than adequately cooled engine that's looking to shed some parasitic losses, NOT an engine that's next to boiling over at every stoplight.
