I have upgraded to a Dewitts FI radiator and built a low profile 2 fan shroud. Since I have a Boost-a-pump that I won't be using I thought that maybe I would try to use it for radiator cooling fan control (aftermarket motors). Has anybody tried this? I figure I could run both fans at 12v when the Corvette low-speed is commanded and when the A/C is turned on or coolant reaches the high-speed temp command then they would be supplied 17+v which makes them spin real fast. I live in the desert so I'm lookng for anything that help while in traffic.

 

Anything is possible is you are willing to go to the trouble of installing extra relays. Also depends on how much current the BAP can support full time.....each fan is fused for 30 amps. If each fan draws 20 amps at 12 volts, and the BAP is only capable of supporting 40amps continuous.......do the math. An additional variable is the fan operating voltage. Some DC motors are rated for 12-24 volts, but it certainly is worth check to avoid premature failure.

 

If they spin too fast they will cavitate and pull less air, so adjust voltage as necessary under that point to get the highest flow. Just 2 cents of info.
