Single or Dual electric cooling fan, PWM, Holley Terminator questions
I am upgrading my cooling system before I install my LS2 in my 64 Chevy Nova. My current 380hp 5.3 runs a little warm (220ish) here in Phoenix with a replacement factory sized aluminum radiator and electric fan. The car will see street and road course duty and will have AC.
I modified the core support to accept a 28x19 inch C&R single pass radiator. I plan to add AC some point down the road. Fan control will be pwm using the Holley Terminator X.
Cool video here on doing that.
My first question is should I plan to use a large single electric fan or two smaller dual fans? What brand of fans are reliable but not overpriced?
Second question is what controller to use, some say the Corvette unit is expensive and not super reliable.
Thanks in advance for your help.
