Pusher fans

[Three Peaks]

Does anyone use the pusher fans exclusively? Do they work by themselves or do they require a puller fan on the inside to provide sufficient cooling?

The appearance is kind of cool and original, but I could care less if it doesn't cool properly and I've hear different opinions on this subject. I would like to hear it from somebody with experience. Oh yeah, I'm running a 351W/393 stroker small block if that makes any difference.

Thanks,
Bob

I use 2 powerfull pullers and I can sit in traffic all day long!

When I had my car all I had on it was two powerful pushers and it never ran hot in our 115/118 degree days. The car could last longer in that heat than I could. I had a 351 stroked to 418 putting out over 500 horse with 10:1 compression.

I think you'll be all right, but the truth is you won't know for sure until you try. A lot of us though just run both. I have both my puller fan and the pushers that you see below wired in to the thermo switch that sits in the lower radiator hose. If you already have a puller fan in your engine bay, I certainly wouldn't take it out, just supplement it with the pushers.

I'm running a puller wired into a thermo switch the pushers are just for added security and wired direct to a toggle

I have four black pusher fans. They are controled in two stages, top two and then all four. Two adjustable thermostatic switches and dash switch, double pole double throw with a center off positionto, to go ahead and run the fans if conditions are anticapated. I have dash indicator light to tell when switched on, Fe with alluminum heads ,no use in letting temps get out of hand. Radiator is leaned back at top. Fans and shrouds cover the radiator. The thermostatic switches were a problem once. Master switch was located in an inconvient location to reach once belted in. So I frequently forgot to turn back on before belting in( lever latch link) what a pain. So I frequently left The master switch on figureing I'd be getting going momentarily. Anyway the hot water would collect at the top of the radiator where the themostic sensors were located. The fans would come on ( they wouldn't make much noise ) Next thing the little battery in the trunk was almost dead. If I had enough electric power to run the electric fuel pump and fill the carbs with gasoline, any incline and it would start. I since incorporated another master switch on the dash that I can reach from the seated and belted in position.

I have one puller fan wired with a thermostat, sender is threaded into intake manifold. I have on the dash a toggle switch to turn fan on before thermostat does (just in case) and I have a light on the dash to tell me when the fan is running. 390fe with 195 degree thermostat in the cooling system and the fan thermostat set at 195...never runs hot. (knock on wood). No pusher fans.

On a side note I would say overkill on the fans will suck some HP by making the alternator work harder. I don't know how much though.

I added my pushers just for looks and have them switched seperately by a dash switch.
If I turn on the pushers before the thermostat trips the pullers, the motor doesn't actually cool down, it just slows the rising heat. Once the pullers turn on, the motor cools down quickly.
The pullers have a shroud around them, which makes them work twice as well. The pushers look great, but don't cool all that well.

Generally, the original style pushers are for looks only. I know they wouldn't even begin to do anything on my car as far as cooling it. But they do look cool.

The pushers look really cool , no pun intended ... but the problem with them is that they cause turbulent air flow and dead zones through the radiator . The puller system is much more efficient for the air flow . Having said that , I still like the looks of the pusher fans .
