I'll try to take a photo tomorrow of the one on my 90 racer. However, I have made back to back runs with and without and it does not seem to help my 1/4 mile times at all. I run it when I race but can't say that it does any good what-so-ever. Some of the other guys may have had better results than I, though. When I set up my IC misting system maybe then it'll help. It is a 10" puller and I have it mounted on the back just clearing the power steering pump pulley by a 1/2". I used a thick copper wire, safety wire will work but I had this on hand, run through the eyelets on either side of the fan and stretched across the front of the IC and twisted tight. The top has a thin steel band screwed onto the upper eyelets and across the top of the IC. I didn't remove the IC to mount the fan. I used a relay and connected the coil to the fog light connector since they'd been removed and use the existing fog light switch to activate the fan.
