Cooling Idea...

[Rosco]

So I'm throwing around this idea: What if I put a small fan mounted to the back of a FMIC? The theory is; It will pull air through the intercooler to the radiator which in turn will get pulled through (Air that is) by the fans on the backside of the rad. Overkill? Could doing this be beneficial? I haven't heard anyone else doing this, so does that mean it's really worth it? Obviously the reasoning behind doing this is to keep the rad nice and cool. As we all know the cooler the air moving through the engine the more happy the car is....So what do you guys think?

I don't mean any offense, but in my opinion I think it is overkill. On my last 240 I had an HKS type-s fmic in front of a Koyo alum. radiator with dual flex-a-lite fans and never had a problem w/ keeping my engine cool. I would prefer to v-mount the radiator and intercooler, but thats a lot more money considering new piping and brackets made for the intercooler not to mention the cost of labor to have someone do it for you (cause I know I couldn't do it). Although I wouldn't worry about it unless your having a cooling problem.

No offense taken, that's why I posted though, to get opinions. I'm just throwing around some ideas. What gave me the idea was seeing some people with those water sprayers (I think that's what they are) on their FMIC. I currently haven't installed my SR yet, I have a few more things I'm working on before I put her in. Just thinking ahead really.

def. to much overkill. you don't want to have to much clutter in that area because even if you have a fan, it is still going to disrupt your airflow. so there is a pretty good chance it would actually decrease the cooling efficiency.

besides when you are driving down the road you are actually getting more airflow than an electric fan can pull so its pretty much pointless.

That pretty much settles it for me right there. Thanks, I was a little too excited that I had an idea that might work that I totally didn't think about that.

what i want to see is a fmic that also has water lines ran through it that circulates water to a reservoir that is cooled from peltier heaters. ...

i guess since i just publicly posted that i will go ahead and build one so i can register it.

[karmakaze]

that could also be used to cool the entire hotpipe.

You mean a water intercooler?

The subaru community has been over this topic many man y many times. The basic theory is:

A fan will pull air over the IC at such a CFM. most of the time (while driving) you are already outdoing the fans by just driving... so when would they be in a benefit? At a stop/start race (ie. traffic), if you need those extra 3Hp while your next in line at the toll booth.

Pointless on a FMIC with driect airflow. A fender mounted IC, I could see having some use, but limited.

One advantage would be the cooling it would provide at a stop. With my theories, much of heatsoak or heat buildup happens to your intercooler when you're stopped. No airflow=heat is building instead of dissipating

But, having that fan there can hurt natural airflow at speed. Plus if you're just stopped anyway there should'nt be much heat being added to your IC. Another but, on a hot day when your IC is already pretty warm its not getting any cooler w/o a direct fan.

And another but, a simple water sprayer setup across the intercooler would do so much better. Could be easily built with junkyard parts, just remember to buy distilled water to spray so you don't leave water deposits. Make sure that if you do run an electric fan setup behind the radiator that some water isn't going to hurt it. While you're this in depth into cooling, go ahead and mount a digital thermometer onto the top of your intercooler giving you an incabin temp reading. This way you can monitor your systems cooling performance and spray water when you need to.

you can get peltier heaters rated to cool into the negative numbers. nuff said.

Peltiers would never be practical in an automotive type application. Just takes too much energy.

im running a stock KA radiator with a Flex-a-lite black magic fan and I live in las vegas, it gets up to 120F here and ive never overheated as long as im modest on the throttle and on stock boost during the day
