Default need help: Adding (2)12v Fans to my Air/Air IC

Would you guys think this would give me a few more pounds of boost to safe out?

I am thinking about tapping into my 12v electrical system so I can mount two fans under my Hood Scoop Intercooler like this:

== <-- intercooler
/ \ <-- 2 fans underneath angled to blow towards exhaust housings

Would it make more sense for the fans to blow to the bottom of the car so that that fan suction is at the hot side or would it make more sense for the fan to blow directly at the intercooler rather than sucking away the heat?

I am thinking of using the fans to suck away hot heat and blow it off... HELP!!!! Theoretical experts arise!

I read that with on a radiator the fans that pull the air through are much more effective then fans that push the air through. That should hold true for the intercooler so go with the fans that pull the air though.

Thanks! I will install the fans right beneath the intercooler, so the contained Intercooler heat will be sucked out by the two fans and then blowed to the floor/exhaust housing. Doubt this will increase performance while on the freeway... but I hope this will resolve some degrees on heat-soaking at the stoplights... I mean the stupid giant intersection ones where you have to wait like five minutes for your green.

My turbo is in the mail and I was thinking about finding a washer fluid tank and filling it with water/ice to have it spray the intercooler whenever i needed a little extra cooling. just an idea

get a seperate water pump and water cooler core and mount it in the fender or at the front of the car route the turbo cooling through the new cooling unit.. maybe get the turbo a bit cooler.

and if you want to use fans use the underneath the IC since they won't be as pron to be damaged by the natural elements.

you'd be better off using a water spray...is this for drag race purposes or daily driving??
