water pump for 360 mild race

Six blades MP decided they would use/recommend for racing because there was less parasitic drag. Eight blades they will provide more coolant flow at idle so if you have something that likes to warm up when it sits in idle but cools down just fine when you get going chances are an eight-blade pump and or adjusting your fan closer or using a larger diameter will fix that kind of thing that all said I just like to typically use the eight blade pump because it will definitely keep the sucker cool while it's sitting there waiting AKA staging...and at that level...you arent using a belt driven fan and can rid that drag to compensate for the extra 2 blades .
