V8 cooling system requirements

I've seen Turbo Turtle's setup with the bigger radiator and all, but I was wondering if there was a way to keep with the stock radiator.

My thought process on this was what if I could upgrade the fans to something with a higher CFM? (what is stock CFM?) I will be using something like this to control when the fans come on: http://www.summitracing.com/parts/FLX-31147/

I also need to find a transmission cooler as I'll be using an auto 700R4.

As far as coolant...... unless there's a better way I was just going to go a gallon of coolant and as much of a gallon of water as I could fit in the system.

BTW keep note that I'm pretty much asking how I can maximize the cooling potential of the stock radiator... if you guys are thinking it wouldn't apply to a normal focus.

any different vehicle radiators you guys have used?

any aftermarket fans that would flow more air than the stock system?

I really doubt it will work very well if at all. You are adding twice as many cylinders (each with it's own cylinder wall exposed to the coolant) and probably at least twice the displacement. Many a hotrodder has gone before you and had to upsize. You may want to look into getting more rows added to a stock width and height rediator. It'll be closer to fitting (may need to work on brackets for wider tanks on either end) in the stock location.

I wonder if there's any kind of auxilary cooler I could use... like an intercooler but for coolant.

guess it doesn't matter but I thought id try. I don't have an issue with making a new bracket... just want to use the stock one.

my bosses jeep needed a new radiator for his swap.

I would run the same.size rad that the krugel component guys were running. 1 question would u see a camaro or nova run a focus radiator? Bigger is better on a v8. My 351w is running a 4core rad,eldelbrock high flow aluminum water pump and a flexilite electric fan w/built in shroud. 180 or lower temps all day long with this setup.

not sure if your still interested but I know a lot of big trucks and other swaps that end up needing more cooling than normal go to the junk yard and get the duel electric fans off of a taurus. serious airflow and if there is no room on the backside of the radiator then ive seen it mounted ( not on a focus) in front of the radiatior to push the air through.

it would be better. question is would it be good enough?

the Taurus has some rediculously efficient fans allowing them to be super slim


google it and look around. I am sure its been referenced before.
