Are they worth the Trouble?

Im just at the stage with my car where I want to get the most horsepower that my car can offer. And I want the car to run at 190 and no higher. So what Im thinking about is electric fans alum rad. and the Moroso electric drive kit that I just bolt on see if that helps. I have a under drive crank pulley so I know thats part of the reason that it runs hot.
