How much CFM on slim fans

[Norcalrallyist]

I am almost done with my fmic install and its obvious that the stock fans dont have a chance in hell of fitting in there anymore So switching to aftermarket slim fans is no biggie but what sort of CFM should I be looking for? Im going to buy this local so I can get this done, so I cant really shop for a specific brand necessarily but I can look for a minimum on CFM. Also what dia fans can I fit?

you can go with the 12" and don't get anything less than 1000cfm you'll find them for roughly $95.00. you can also go with a 10 and a 12 or how ever you want it. just nothing under 1k cfm thats factory. I'm getting mine next week something like 1300 cfm.

Go to RRE and get your slimfans there.. Ask for "Jack"...

You can get away with running one 12" fan as long as you dont have/use your A/C. Just make sure it is at least 900+ or so CFM. You can fit a maximum of two 12" fans on our radiator core.

After switching to an external wastegate, my second 12" fan got in the way of my wastegate's dumptube, so I switched to a 650 CFM 10" fan.

I ended up with a 12" zirgo supposedly rated at 1650 CFM and ill just not use my A/C til I get another fan.. Its the middle of winter soooo...
