Fan (push or pull) for P1SC Procharger kit I installed a P1SC Procharger kit on my 98 LS1 Camaro. I hooked the fans up according to their directions. As the car got warm, I noticed that the fan is pushing the hot air through it. For example, the fan is pulling the hot air from the engine and through the radiator to the front of the car. Is this correct? I thought it was supposed to pull the hot air off of the radiator?

FYI...this is a neat tidbit of info I found out in a non-automotive application. A pusher fan pushes about 30x it's diameter of air. A puller fan of the same diameter only pulls 2x it's diameter worth of air. So, using a pusher fan is about 15x more effective than a puller. Makes you wonder why OEM's rely on puller fans......

National Fire Prevention Association. They did research on fans/air volume to clear smoke from buildngs.
Don't have to believe the results.....just throwing it out there as an interesting bit of info I learned concerning fan efficiency. 
Also, this is relevent to total air volume being pushed/pulled. I'm sure NFPA didn't test the efficiency of this theory when moving air through a radiator/intercooler.

BOSS APPROVED! Just a thought.
For sure not me. I had to add a 9 inch fan, a tranny cooler with a fan, and finally a fan on the a/c condensor. I wish that would have been my problem.
