I been all through this , Fast truck has it right . Water is best at transfeering heat . The water wetter is supposed to help but have heard it were it did nothng , yea I poured a bottle in my drag car .Anti freeze is just that and a anti corrosion agent .
On my nova i have gone to a electric fan, A few extra HP from not having that fan to spin and better cooling . I use a 2 spd fan from a ford Taurus , pulls a suprising 3200cfm
