Is it possible/reccomended to take the Stock engine Fan out, and replaced with an electricFan on the radiator?

 

It is possible. Why do you ask?

 

Im planning on installing an Aluminum Radiator in my car, so i was wondering if installing an electric fan would be more efficient than the stock engine Fan.

 

technically yes but it depends what else you are running

The engine fan does rob some hp, but not that much that most people would noitce.

If you go electric fan, you need around 2000cfm for a stock/mild v8 so you need to make sure you get a big enough fan - like 16" (around 2800). a 10" fan generally only flows 1000 so even with 2 you just get 2000. You have to mount the fan close, but dont let anyone tell you its ok to use cable ties to hold it to the core...a simple bracket arangement will do. All fans work better if shrouded. (See pic, this is for a 580hp car, twin 14" at 2000 each and fully shrouded)

You can get a straight on/off fan - which is simple but you have to remember to turn it on or get it hard wired to the ignition so its on all the time. If you chose option 2, they do draw quite a lot of battery power so you need to be comfortable your alternator, battery and wiring are up to scratch.

You can also get a thermo fan where a thermo probe goes into either the radiator or the top hose and turns the fan on automatically when it is required (which is rarely once you get above 35mph unless its a stinking hot day!). Again you need to be confident of your wiring because fuses only blow when you really need them not to!!
