Re: To electric water pump or to not???
dragon0123: I have been running a proform 35gpm electric pump on the street and track for three years now. I absolutely love it as the temp in stop and go traffic stays between 180 &190, no matter how hot it is outside. I attribute this to the much higher coolant flow at low engine speeds compared to a mechanical pump. At the drag strip, i have got the car cooled down between passes in 5 minutes maximum ,compared to 20 minutes with the stock pump! Just remember not to run a thermastat with a electric,use a plate with a .750 dia. hole in it in place of the stat. or take the guts out of a old stat and put it in your housing. You also give up being able to run a heater in your car because of no provisions for heater hoses on elec.pumps, but more than worth the sacrifice to me! I also went 1 tenth quicker in the 1/4 with the elec. pump!!
