Turbo23, I really have to say I am very proud of you for bringing an old school hot rod method and using it to resolve a very real issue with our top mounted ICs. I was at a car show today and saw a couple of really old hot rods that had fans hooked up same as you, forcing the air through the radiator. some had two fans! Good s*** 23! thanks for doing the experiment and sharing with all of us!
Screw your FMIC

both especially if you use a fine mist with 50 50 alchy. Evaporates on contact
I have used that setup on 300zx's sucessfully and intake temps dropped quite a bit . On a top mount setup a fan would help with heat soak significantly. You still have the issue of the top mount being very restrictive though.Harry
GHETTO !! and it wont do too much of anything to be honest. just like the fans at a dyno shop. it will never move enough air at enough speed to keep it "cool" it will prevent horrible heat soak i guess, but it also is now a huge restiction for real airflow that covers about 75% of the cooling surface of your intercooler. take it off and buy a co2 sprayer if you have to. there is a reason nobody has done this.
er blocking air flow, well it doesnt really do that, IC feels exactly the same. And as for doing nothing, I can sit in traffic with the fan on, and have a nice cool IC, even with the engine bay very hot. Most dyno fans actually work quite well, especially when tuning my Rx7 which needs air for oil and coolant temps more then anything! Alot of old school rally cars did it, and the reason why alot of people havent done this....not many cars have the top mount. Sure a wrx does, buts its tiny. CO2 works well, but you just cant keep a continuous flow of CO2 blowing on the IC all the time.
The fan worked great during the autox today. Alot of people loved the idea, and a couple evo guys want to install one in their hood vents to draw out the hot air. I would say 810cfm is a pretty darn good air flow, the air coming out the other side is very strong. So take it or leave it, Ill keep the fan.
Just a comment. The screws that hold the motor together for the fan do rub alittle on the hood, which only started happening during the autox today, Im assuming from the harsh throttle inputs causing the motor to move. I may eventually try to mod the underside of the hood to allow for more room, but air being pushed in will go right about the fan motor.

Is that a stock TMIC? If so, I assume this would not work with an ETS because of the thicker core and less clearance?
if you dehumidify that 810 cfm you could cool a small apartment
someone should figure out how to re-work the AC ducting to the intercooler...
That is genious! Run the a/c ducting to the intake. Suffer for the sake of performance.

I want to say I read a car magazine article or Q+A a few years ago that said that at least on n/a cars the ammount of power it takes to run the a/c is more than power gained by trying to cool the intake charge.
Now if you try the same principal with fi and an intercooler, it might work. I still think the cooling charge would not be worth the parasitic engine loss from working the a/c system. Spray (CO2, N20, etc) ftw!
all cars have fans on the radiators. Alot of old muscle cars use eletric fans b/c they have crate motors that don't work really well with their old engine fan and usualy don't have the clearance to run a fan like that.
Off road is a big advocate of eletric fans. Running them on radiators in the beds of trucks like on tough truck racing and rock crawlers, etc.
Great idea on the fan. i like how you can switch it on and off when the car is off. So you can blow all the hot air out of the bay quicker.
But dang that thing is loud in that video. haha
Is that the thinnest fan you can get?
that is the thinnest fan I have found that flows that much. It would be hard to beat what spal puts out for fans. Im also thinking of mounting a metal plate behind the IC. Not directly behind it, but over the turbo heat shield. The metal heat shield would be coated in gold heat tape, and its main goal to prevent alot of the direct heat thats throwin from turbo at the IC. It should be simple, and effective. I would also like to raise the rear of the hood, by perhaps running some foam around the IC shroud to make sure there is still contact with the hood. Also removing the weather stripping at that time. I know alot of 3rd gen rx7 owners, and 2nd gen owners that have seen great results with this. However contrary to what most people beleive, at speeds it would not release hot air, it sucks in air. But during stop and go driving, heat would be release from the rear of the hood.
er are turbos are water cooled. It would take a MASSIVE amount of air, and some engineering to cool the turbo via air. Very little of that air would actually reach the turbo, and is blocked by the heat shield anyways. here is a pic of my FC rx7, notice the heat blanket, I have ZERO air being forced on that turbo. So there would be no effect from blocking air.

+1 our turbos are water cooled so air is little or non efective on temp. This is also the reason a turbo timer is not necessary on our cars, just a quick idle b4 cut of.

turbo23, how is the fan working still, any difference when driving at high speed like 100+mph, any new data
Theoretically there would be no difference at 100mph. This mod is to eliminate heat soak while the car is at a stand still. There is already a s*** ton of air passing through the TMIC at speed.
