Electric radiator fan recommendations
 

Shopping for an electric cooling fan for my '78 Camaro stocker with stock size radiator. What size, cfm rating, and amperage would be sufficient for adequate cooling ? Curved or straight blades ?

Joe, I have the same car as you. I use a Flex-a-lite fan # 118. 2500 CFM.
Works good for me. I do not use a shroud, for no particular reason.
18 Amp draw, be sure to use a relay.

Terry, thanks for the reply. What combo do you run ?

Re: Electric radiator fan recommendations
 

Chevrolet HHR from your Chevy parts department is a nice one. It has a built in shroud. It fits my 68 Camaro like its factory but your radiator is probably wider

Joe, I run the 175/275 HP, 350 CID in "I" trim. Stick setup.
I run my car as a coupe. The Z28 is to heavy to be a natural "I".

Shaun,
I own a 2011 HHR as my daily driver. That's an idea. Hmmm...

Why is a relay needed? Just curious, I've never used a relay, just a toggle switch and an inline fuse.

Re: Electric radiator fan recommendations
 

It's a lot of amps to pull thru the switch. The wire can get real hot. This way the switch only triggers the relay.

Re: Electric radiator fan recommendations
 

I don't know what the CFM rating is on it, but when you turn that thing on you know it !!! It pulls some pretty serious air .

A little off topic, but are there any books that cover basic race car building? That would answer wiring questions and such. Seems most racers, even seasoned ones, have many different methods to builds.

The book I use the most is the cheque book!

If you use your standard 30 amp relay and spade connectors, you might want to squeeze them a bit with pliers. I've seen them melt and burn up at that point.

Good heavy duty switches are hard to come by. Stop by your local small engine repair shop and have them order you some chain saw switches...chances are they won't have any in stock because they never fail. They will utilize a screw terminal instead of spade connectors.

!0-4 on the relays...make a world of difference. Quality stuff here... http://www.leashelectronics.com/

If I remember correctly I bought mine at the local parts house. Advanced Auto parts. Nothing fancy but works well cools good and has been reliable.
