Electric cooling fans

[Cainsable]

I am going with twin 12" fans, just wondering should I have them blow through the radiator to the outside or pull air in from the outside into the engine compartment

Pullers are generally better than pushers for radiator cooling.

Yes and make sure you use a shroud that covers the entire surface area of the radiator.

i'll second the puller fans. they are moooore better to cool. if u can get a shroud with the fans that's a really good idea, but if not then get fans with max coverage.

I have two electric fans: 1 puller and 1 pusher.

I Don't know if this is more effective than 2 pullers…

I'm thinking about reinstalling a 6 blades fan on the water pump and a fan shroud instead of electric fans...

It depends on how much of the radiator the fans cover, how much has air flow through it, and if you have a shroud on the puller side. Offsetting the fans would help to cover more area.

Hi

I made a shroud and squeezed in one 12 inch and one 16 inch. Works great

Robsweden,

2 pullers or one puller and one pusher?

+1 I run a stock fan with the original 73 radiator and shroud and have no problems at all keeping cool.

The glimmer belt kit is alright, as long that you have Place for it. Cool winning sound when revving

How loud are they ? I know that is a hard question to answer, but I have dual Spal fans, and they what I would consider REALLY loud. But maybe that is normal.
