Yes, I ordered directly from Griffin and they do have a website. I looked at that AFCO, which I think is actually 80133N, but it's 16" high and I didn't think it would fit in the vertical position. Now I realize it might fit if the reinforcing under the hood is cut but I prefered not to do that. I couldn't find anything to fit any better that that Griffin - I even had to cut away metal above the a-frames, put in some pretty thin silicone padding and slightly bend down the aluminum rib on the top to be able to close the hood.

I bet Don can get away without a fan shroud considering his V6 and living in Idaho. But for a V8 and hotter climates the shroud is probably going to be necessary.

Tyler,

You're right, it's an 80133N. I didn't need to cut any hood bracing when I tipped it slightly forward. Here's a pic of it in place with partially completed ducting to vent through the hood. Ducting now has a flange on top for 1" foam rubber to seal against underside of hood.

Andy,

I haven't built my shrouding yet to seal the radiator and direct flow in and out (and prevent recirculation) because my install is very new and, since I'm approaching winter here in the northwest, its not a high priority until late spring. I do plan to install shrouding before then.

With regard to mine, it's not fully complete.........Shrouding TO the radiator is definately planned.

Andys - Did you get your fan set up and shroud from AFCO as well???
Your set up looks pretty clean... (IMG:http://www.914world.com/bbs2/html/emoticons/smilie_pokal.gif)

Thom

Thom,

I made the shoud. In the below pic, notice the (orange)flappers that allow additional air to pass at speed. The fans are made by Zirgo. You can buy directly from them....Don't have the site handy, but it's probably zirgo.com. For shroud and fan assemblies that you can purchase, I have some info at the office I'll post tomorrow.

Andy -
Thanks for the great info - What did it take tool wise in order for you to make your shroud? TIG, brake press, etc.?
I also wanted to ask you if you removed the horizontal support at the front of the car, right below the latch ? it looks like that is the case in the photos above...

ive checked out where the hoses enter the front compartment and when i looked today it doesnt look like there is enough room to get the pipes past the rack can anyone post a pic of this as so i can check i know my car has had a new front floor however it looks fairly stock
it also has 911 struts in the front with the lower control arms that have the front swaybar/torsionbar brackets on them, dont know about the rack though (IMG:http://www.914world.com/bbs2/html/emoticons/confused24.gif)
the car is 75/76

looking at the steel but dont know what to use now
had a look at the other car here with the sti wrx & six speed its a race car but he has used ally pipe inside ally pipe and run it down the centre of the car (inside) the outer pipes exit right out of the cabin incase of a problem

what thoughts is there on this approach

the shifter is an auto so it can be mounted above the pipes

From all I've read it is best to avoid running piping through the driver/passenger compartment due to excess heat (914's get hot enough inside as it is) and the danger of a blowout in the pipe and 200 degree (f) coolant being sprayed around inside the car. That may not be a problem with a double wall pipe system except in case of a crash. The defacto standard seems to be 1" (25mm) rubber heater hose beneath the chassis (see photos below of how I did it). You can also see the earlier photo on page 2 of this thread where my hose exits into the front trunk of my red 914. The rubber hose was the easiest for me to do based on the limited tools I have. Others have run iron pipe in the same location as I've run the rubber hose (the two indentations in the chassis that run along side the center tunnel beneath the car).

Thom,

Yes, it took all those tools to do the fabrication. I did remove the sheet metal in the front bulkhead below the latch. I left a center rib (and re-enforced it) to help stiffen the latch. I will be cutting a grill opening in the front bumper. That's the plan.
