what is the cooling campared to a clutch driven? reason i am asking is i am thinking about using the electric fans to cool a big block and think this is the cheapest way out of that hp robbing clutch fan!

thanks, critter

 

There should be plenty of air provided by the dual LT1 fans, IMHO.

thats the only like i have seen in terms of wiring this, have you seen any how to's on how to wire one up on a non-pcm car. it would be going in a 1970 454 el camino. the only way i could think up is to emulate that wiring and use the manual switch to turn it on and off.

p.s. should i be posting this somewhere else?

 

You can buy switches that plumb into your cooling system and turn on your fans at whatever temperature you want them to. Check Summit or Jegs.

 

If you can put a temperature switch as well as a manual switch, Temperature switch will screw in anywhere, side of the head, into the block, water pump hell even the radiator, anywhere theres a tapped hole and it will come on automatically so you dont have to remember and the manual switch can be if it ever fails.

 

so it would work the same way as the sensors in my water pump and the sensor on my passenger side head?

how would i wire this? this is the first time i have gotten into wiring. thanks for all the help so far.

 

Just a note you're only really best switching to electrical if space is a concern. If its not a tight fit i'd stick with clutch driven...

 

well i have been doing some reading and have seen some dyno's where on some of the older engines see big gains from converting to electric fans. in one case they guy picked up 34 hp?!? there was another on a 302 87 mustang that got 10 at the wheel from it. also there was a report in car craft i believe with some more dyno's to support this.

i can get the fans for 30 bucks and i'm an electrician so i figured it was worth a shot.

 

Is this question in any way related to an LT1 engine?

 

then move it please, i did a search trying to figure out where to put it and the last time anything was even said about fans in the electrical section was 04. i searched here and found at least 8 within the past 3 months.

and Injuneer do you have any suggestions on this in terms of wiring it.

 

Get a temperature dependant "fan switch" and put it in cooling system somewhere that can read the temp of the coolant in the heads, or returning to the radiator. Wire the electric fan directly from an unswitched +12V source, using an inline fuse and a relay. Use the signal from the fan switch to turn the relay on and off.

 

thanks a bunch man

 

If you check jegs or summit there are different electric fan options. I am looking at a setup made specifically for my 5.0 from proform, thats only like $140 that includes a temperature switch and an electric fan.


Another option is if you check out Advance auto they seel a temperature switch. They have 2 one that works around 180* degrees, and a an adjustabe one. I beieve they both run of a thing metal rod that you slide inbetween the fins of a radiator.

would the above link have everything besides wire that i would need to get it to work without having to use a manual switch to turn it on and off?

also would the fact that there are 2 fans make more relay's needed or could i wire the 2 + and 2 - together?

 

bunp anyone on this link? ^^^
