im going to go over my cooling system this week, and i wanted to know if a 23-2500 cfm fan will be enough to cool my car down?

im also putting a new stat, high pressure cap, 70-30 coolant to water, neocool, flush and fill the coolant (fc3s pro modified technique)

i have a
3"exhaust, tb mod, sheepdog bov, greddy intake, fcd, 680cc injectors, new wires, and hks plugs....

runnin 10-12 psi on 93 octane

 

Anything over 2000cfm works...

The 70/30 coolant/water will give a higher boiling point as will the high pressure cap, but the FSM recommends 50/50 coolant/water because ethylene glycol is not as good of a heat transfer liquid as water.

 

so 50-50 is good to go?

thanks

I have found that electric fans let the temp go up higher. the best setup I have found is go to the junk yard find a shroud that fits the radiator with a 17" hole so you can fit a 16" fan in there then go to JEG's high performance website or call 1-800-345-4545 and order part# 771-19115 16" perma cool electric fan. it flows 2950 cfm and will keep your temp down. the shroud helps a grip so get it. let me know if you have any questions.

 

how much is the fan? perma-cool aren't they expensive?

thanks

holy snikes!!! its only 90 bux are you sure its that one, if so ill order it friday!!!

thanks
alot

should i get the perma cool fan wiring kit?

or the painless wiring kit?

the difference seems to be the painless comes with a relay, and is automatic, and the permacool is manually adjustable, and i don't think it comes with a relay, but i can buy a relay at like radio shack, and i want it to be manually adjustable....

just wondering what your setup is?

thanks
rocky

 

get what ever would be easyer for you I always wire my own setup. but this is hands down the greatest setup. you need the shroud though. thats a biggy it does have to be big. Just enough to reach the blades.

 

ill be in the junkyard on sunday then hehe....

 

bump I have been seeing alot of cooling Q's and this is the answer.

 

any ideas what has a 16" shroud that will fit the need? that way i wont have to go hunting with my tape measure

 

I dunno I got mine from a pile of them. but I need another for my other RX7 so I will see what I can find. what about you dra gon lee did you find anything.

(lol should be dra gon Li )

 

lol, i didn't go... i got the 14" fan instead, it pulls just as much cfms and im gonna trim and use the stock shroud....

dra_gon_li? now thats just gay hehe jkin

also my filler neck is broken, and its letting air out of the cooling system throgh the cap, i think thats another reason shes runnin a tad hot...
