Re: Installing pusher fan?

The ruff running u experienced is most likely due to the gasoline getting hot and trying to vapour lock or perculate but just border line enuf to allow for continued running. This happens to me here in TN. on occasion during the very hot summers but not often enuf for me take any major effort action. In fact i have a NEW (as in BRAND NEW, not rebuilt NOT recored or anything like that) and will occasionaly experience a stumble or some ruff running under high heat conditions. I also have a large SunPro engine temp gauge to monitor.

The fact that the radiator in your car is not puking out any coolant pretty much rules out overheating or at least rules out any overheating that would be considered detrimental. CHECK THE PRESSURE rating of the radiator cap.

The pusher fan mite help. MAYBE. I ran a pusher fan for a couple of years with absolutely NO evidence of running cooler or better or anything else positive. The pusher fan i used was some junk yard find and i have no idea what car it came from. It was large too.

THe problem is that the pusher fan will tend to block (somewhat) the air flow thru the radiator AT HIGHER SPEEDS thus causing some higher engine temp.

The pusher fan is something that the hot rodders use because of cobbled up engine compartments that do not readily allow for an easy mount of an engine driven fan. In somecases the hot rodders do not want to rob the engine of any power to drive the fan so they use an electric fan.

Since it is BY DEFINITION a HOT ROD ergo they tend to run such high performance engines at rather high temperatures anyway.
