Low off of one toggle , HIGH off of another. Mechanical gauge. Intake only has one port.

If you want serious cooling, it should be the other way around for your pulleys. 8" crank. 6" water pump. This will over drive the pump by 1.5~ish. More like an AC set-up.

well that is how I ran mine was low speed with sensor high with toggle, but for some reason it showed 195 on my autometer temp gauge when it kicked on.. Not sure if that sensor was funky or what? Cause the one Dave from hollister sent was tested to open at 181!.. Do U use any sealant on yours? The only reason I have the 6 " billet one is cause of my previous problems I am sure u read about late last fall with pulleys breaking which we now now was the crank harmonics! that is why I want to go back to the 8" and my 6.25 water pump to over drive it again!..
