Had a couple of cooling related issues. First off the autozone chrome water inlet on the intake manifold has been corroding away on the inside and finally corroded so far that it created a leak. Pretty bad.. So I drained and flushed the system and installed a factory cast piece that looks like it wont ever have that problem. Took a couple of tries to get all the air out of the system but I did it.

Another issue I had was I had a pusher and a puller 12 or 14" fans (cant remember) and the pusher's connections broke and caused for fraying of wires and a contained electrical fire. I removed the pusher and have been running just a puller, however I wired it backwards on accident and I also decided that one fan just isnt enough. So while dad was picking up some bolts at pick and pull for my honda he picked up a Lincoln Mark VIII radiator fan. 18" of fan glory that fits the radiator PERFECT. MY OH MY does this thing suck air. Absolutely dwarfs the old fan and supposedly pulls 4k CFM. I have it running on just the LOW setting and will setup a separate switch for the HIGH setting (its a 2 stage fan). The only thing I think I have left to do for the radiator is setup a duct to force the air out the wheel wells as I think there is some turbulence currently and I dont think its as efficient as it could be.

What size inlet hole did you cut? Mine seems much smaller than modern renegade conversions, and I wonder if this is causing my 200 degree freeway temps.

Mine is the entire width of the front trunk, from fog lamp gril to fog lamp grill. The key is to have twice as much on the air exit. That way it creates a low pressure zone. My rotary stays at 180 and slowly creeps to 200 if I'm not moving.

My inlet on the bumper is ~ 5.5 x 21"

You can see the bumper cutout in the pic Jim posted, the cutout in the front of the trunk is a couple inches larger than that. The problem that I see with the inlet setup right now is that air that goes through the hole in the bumper isnt forced into the trunk, there is a couple of inches around the bumper all the way around between the bumper and the trunk. If I eliminated this gap with fiberglass on the bumper I suspect more airflow at higher speeds (Granted I dont have cooling problems at high speeds except on hot hot days).

And Mike has it right, the biggest thing is 2x the outlet as the inlet. Which is why I believe if you shroud the outlet the efficiency of the hole size would be much increased, for example you would only need 1.5x the size.


Just one of those things im looking to experiment with.

I have a rubber dam between the bumper hole and radiator. This forces all the air through my shroud.

You can barely see it if you look through the grill. I would have to dissassemble the shroud to get a picture. It's made from a bed liner mat. 1/4" thick and cut to shape.

EDIT: Found a pic. Not great but you get the idea...

So that material attatches to your bumper? Looks like that kind of thing could certainly work.. Better than hours of fiberglassing...

This is just a teaser to some of our kick ass engagement pics. I was able to convince her to let me incorporate the 914 in some of our pictures. Were really happy how these have turned out so far and we hope you guys like them as much as we do! I'll post up some more in a couple of weeks.

Very sweet. Congrats Andyrew, you have rocked it yet again.

Take this with a grain of salt: The rockers.... dude, what you going to do wit the rockers? It seems like the flow is interrupted by the fender. Body color? Blacken bottom edge of fender to continue the stripe that's in front and behind that spot?
Not picking on it - amazing as is, just thinking out loud.


(IMG:style_emoticons/default/agree.gif) Still, this is an awesome 914!! Great Job!!

There is a 914 going FROM the wedding (IMG:style_emoticons/default/smile.gif)

Update on the car, Going in for a dyno tune tomorrow. Im looking for 225whp and 250wtq. (I have to consider that I have 100lbs in wheels and tires in the back) but most importantly im looking for smooth tq curve, smooth power through the powerband, better cruising (it never was that bad..), better cold starts, and better gas mileage.
