Win a Free Beer!

WF10 contest. To win a free beer, you must be the FIRST person to PROPERLY AND FULLY identify what is in the center of the pictures and what it's purpose is. Contest open ONLY to those going to Wagonfest, where they may pickup the prize. Winner must be over 21.

Winner announced before WF10

(I'm the judge of what is proper and full identification... so bite me)

That is a fan and it is for cooling! Make sure the beer is nice n cold.

Easy, CPU cooler. Congratulations on the worlds first AMD (or Intel) powered wagon!

Computer CPU cooler, cooling what appears to be an ignition module?

Is that thermostat controlling the fan? You should be able to pick up a computer case fan with built in thermostat. They don't completely turn off but they slow down and speed up as needed..

wow,. an electrical supercharger with intercooler,. i seen them on ebay!!

Thats a CPU cooling fan, and it appears to be cooling and HID balast?

We're talking FREE beer here guys...

Two weeks before WF10


Anymore guesses?

It also appears to have a thermostat setup to control when the fan comes on.

I'm seeing partial answers here but the rules state...

"you must be the FIRST person to PROPERLY AND FULLY identify...

Partial answers are not going to win the free beer. Make it complete.

Allow me to combine my answers then. That is a CPU cooler with an electric thermostat (possibly out of an air conditioner) that is cooling and HID ballast.

What's an "HID ballast?"

Woops, too many "l" in there. Its the power supply for HID head lights. I am guessing I guessed wrong lol.

It's a CPU cooler (perhaps intel), wired to an aftermarket (adjustable) rad fan controller, cooling some form of ignition module that appears to be part of your Accell ignition system.

Polish headlight fluid cooler?

It's a remount mounted, GM HEI Ignition Control Module cooled by a temperature controlled fan with heat sink, coupled to an Accel 300+ double strike ignition. It's in, complete and it works... so far without issue.


In the center of my photos is a remotely mounted GM HEI ignition module, cooled by a typical computer heat sink and 12v fan combo. The fan is thermostatically controlled by a secondary radiator fan sensing unit from Advance Auto. ($19.00) The unit is set to start the fan at approximately 140F, which seems to work well so far, considering I don't want the fan on all day draining the battery with normal under hood temps on a black car just sitting in the sun. I set it with the use of the old family hair dryer and an infrared temp sensor gun from Harbor Freight.

The whole system is wired in a fused circuit directly from the battery so that it can still run after the engine is shut down. I did not want the cooling to stop when the ignition was turned off. Works just like some radiator fans do, that even though the car is off, the fan can still keep cooling.

As suggested by responses questions fielded at http://www.thirdgen.org/techboard/diy-prom/578176-remote-ignition-module.html ...the cable from the trigger coil inside of the distributor is a high temperature, shielded, twisted pair. It was a pain to ground it at the distributor side, so the shield is grounded at the ICM heat sink. Being near the ignition wires does not seem to have any negative effect. The four wire group from the ECM to the module had to be lengthened. I used soldered connections throughout.

For the female clip connector from the trigger coil to the module I used a spare from an prior coil that fried. The male end was cobbled up from a box of ECM repining ends that I found on a rack at NAPA. The pins were then placed in a little wad of 2 part epoxy putty to form a block shaped connector.

So here's the why part: HEI internal module systems are prone to self-distructing due to the high heat environment that must survive in. And that's at a stock level.. Add high performance goodies like headers, and that overhung cowl of a Caprice, and you might as well be baking chicken while you are at it. So what I've done is taken a module out of there and put it in a much cooler airstream on the fender, and am helping it remain cooler with the heat sink and fan set up.

The whole system can still easily be returned to stock, but given Shammoo's past issues with fried ICM's that's not likely to happen any time soon.

so,.. i didn't win?
i liked my answer better,. i knew what it was,. but i thought the answer was too easy,.

with hydro thermal dynamics,. does it mean the fan is still coming on 20 mins after the car shuts down?

Great answer Mike! (except it's Lithuanian, not quite Polish, but close.)

Hey Nick... the good news is that I haven't forgotten that I owe you some Corona's. You'll be getting some beer regardless!

In all seriousness.. to answer the part of your realistic concern about "fan on time", I just came back from a data logging session, and immediately flipped the hood open.. I hit the cooler assembly with the laser thermometer. It was at 152F (68C) and turned off about three minutes later when the temp dropped to 134F (56C) Granted, I helped the cooling process by opening the hood.

At any rate, 152F is a vast temperature improvement compared to sitting under the firewall cowl, atop a hot heat soaked engine, next to 700F headers. In comparison,. the top of the plenum was at 185F at the same time. I'm very happy with the results thus far.

Wicked! I love me some local microbrews!

So that explains the thermostat! After ignition-off cooling..

Yup... you got it!
