I bought a flex-a-lite "black magic 150" and I could not believe the difference. Not only does it have a larger cfm but, the shroud is fantastic. All the incoming air now goes through the fan. With the temps yesterday of 103 deg's, the water temp never got over 200 in traffic. (I do have a 160 thermostat though, for summer heat) In previous years, I wouldn't even attempt driving it this heat. Anyway, yes........build or buy a shroud, it will help out tremendously !
