I/C Electric Fan Mod Done

[FastRegalWE2]

Ok, so I didnt get any beforehand temp data, dont have a Raytek and was in a hurry to get this project done.

What I did was take a smap Spal electric fan and mounted it to the backside of the stock I/C. I figure I am benefitting in the following ways
1. Less mass on the snout of the crankshaft
2. This thing pulls a ton of air across the I/C
3. Less drag on the engine

who knows what else.
Anyway, the fan fit inside between the outer edges on the surface of the I/C. The mounting points even lined up with the rows of fins. There is approx 1/4-1/2" of clearance all the way around the fan with the harmonic dampner. Have had no probs at 22# boost so far. I modified the original connector on the fan and made it GM weatherpack and then made the second harness for the power and ground the same way. I removed my fan resistor and hooked the I/C fan in with the radiator fan and they run on high speed only with signal from the ecm. With my backyard testing procedure I found that the up pipe IS noticeably cooler to the touch after a spool up now than it was before. I also have a slight bit less of KR. Dont know if that is the fan or something else but it seems that it is attributed to the fan. I may have to put a screen on the I/C scoop because the scoop is like a vacuum cleaner and I may get some debris in there now. This fan really PULLS SOME AIR. I will try to get some pics this weekend or something and put them up if anyone is interested, or if anyone nearby wants to come take a look see feel free.

I've been toying with that idea for a while now but never had the time to try it. Glad someone finally did. Can't wait to see pics and how about a wiring diagram, would like to do that to my GN this summer.

I wonder if you could install it on an aftermarket stock location one. I want to get a thunder fab soon and might do elec fan also.

It actually allow MORE airflow then stock fan.

I was thinking, I have this wired to the stock fan which is activated by engine temp. This is probably hurting more than helping. I need to find a pressure switch, I thinnk 1lbs activation so that as soon as the turbo starts to spool it will kick on the I/C fan.

If anyone is interested, I can get the fan model number and cfm rating. I need to get some pics of the set up too. It wont be on my car much longer as I have bought a used front mount.

have the fan run all the time and have a hobb switch turn it offat about 5 psi.

I've had an ic fan on my stock location v4 for about 18 months. Main reasn for install was for stop light idle, staging lanes, dyno pulls. I usually leave it off driving around or when I make a pass on the track. Definatly helps prevent heat soak while sitting in the staging lanes.

 

[TR Custom Parts]

Would be cool (no pun intended) if could be hooked to a speed related sensor so it would only come on when the car is stopped. Of course you would also wire in a manual override switch for staging lane duties.

How about posting some pics and part numbers?

 

[REDS HOT AIR]

yeah if you turn it on with boost it will do no good

it needs to run all the time

its too late to cool it once your in boost the temp dont instantly change ..the i/c acts more as a heat sink

while making a pass the i/c absorbs the heat out the charged air then it slowly cool it back down

typically if you felt the i/c at the end of a pass then drive back to the pits thei/c will be hotter after in the pits because its releasing the heat it absorbed

I like your idea. What size fan did you use?

 

[FastRegalWE2]

argh, I thought I wrote it down but I didnt so Im gonna have to look it back up. Will post it sooooooon. Im working on pics too but Im going out of town this weekend so maybe Mon/Tues pics and specs.......

 

[INEEDAGN]

I would also like info on this setup so please post it when you get it.

I used a 10" fan from o'reilly's(HI/LO), I believe the thickness was about 2-3/4". Runs off a relay controlled by a switch inside the car. Pretty tight fit between the i/c and crank pully, about 1/4", but has never come close to rubbing. Used the supplied zip tie things to hold it to the i/c. no problems after 18 months of use.

32101-SUF 10" Puller 2.050(motor thickness) 1.100(fan thickness) 650cfm and it has the skewed fan blades
that is the fan data.......pics are going to be on later tonight or tomorrow

You know how you can get those fan controllers for radiators that include a thermostat (thermocouple) which cycles the fan based on temperature? I don't see any reason you couldn't use one on an intercooler

I wouldnt know what temp to put it at, very low I suppose. I had even thought about wiring it to the fuel pump relay to get it going constantly to maintain flow as the stock unit did. Im sure there are a few different wasy to go about it. With no test data, dont know what the best would be.

Could this work on a front mount?

 

[FastRegalWE2]

dont see why not, I have thought of moving it to my fm as soon as I get it on, of course I would need a "pusher" and not a "puller" fan. Not enough room to mount the IC fan I have now behind where the FM is going to be. I have the brackets in for the FM and its all been spaced and set up to mount. I had to get it cut down from 30 rows to 25 to fit. Dual fans or a larger 12 or 16" fan would prob fit also. At least on my FM it would.
