I had a black magic on my old coupe which made close to 300hp at the wheels. I used to drive it to work every day 86 miles, a lot of which was uphill. It gets hot here in southern Ca. and the fan did great. I like it because everything is built right in and you can get it installed and working perfectly in well under 2 hours Plus flex-a-light sells parts to rebuild it....motor, blades, etc etc.
