Overheating Issues, Perplexed

[DAVID GAGNARD]

Fred;


I looked at the site the other day and again today and found this, doesn't make a lot of sence to me.......

Increases cooling by speeding up water flow and fan speed. This helps at critical low speed driving where most overheating occurs. Precision CNC machined from billet 6061-T6 aluminum. Finished with a “No Polishing” clear powdercoat.

I have fairly new glasses and according to what I read on the March site, all the crank pulleys are smaller in diameter than the water pump pulleys listed!!!!!!!!!!! how can that speed up your water flow when your slowing down the water pump rpms?????? dem guys at March must have been smoking some really good stuff that day!!!!!!!!!

I'm sure if one called them, they would be able to get a water pump pulley of the size needed, I know March makes many different size pulleys............
