So we got our electric fan setup in. It is the Spal fan that puts out 1610 cfm and is 2.48" thick. I hope it puts out enough air to keep the car cool in our hot summers.
Got our -10 AN line:
The fan is pretty easy to install. I centered the fan and clamped the straps to the radiator. You have to off set the hole on the strap in order not get in a larger hole on the radiator(you wouldn't need to do this if the fan was a little off center). Then I primed, painted, and pop-riveted the straps to the radiator.
I was able to get the stock shroud on the radiator with no modification. I think I do want to trim it down to make it have more clearance between the resevoir and the valve cover. The clearance between the fan and water pump is about a 1/2"
Here is the clearance from the oil pump nut:
I made a tight radius 90 degree for the bend off of the throttle body. It came out really good. We are trying to figure out what finish we want on everything...so for now its brushed aluminum.
So I got the last tabs welded on top of the intercooler. It all fits up perfectly and the intercooler and oil cooler will be mounted so bomber that you could pick up the car with them. I also welded on some tight bends for the charge pipes so we could still use brake cooling ducts. For the hot side 2.5" charge pipe I put relief cuts in it and flared it out to 3". We should only have 2 silicone couplers per side of pipes.
To mount the oil cooler on top of the intercooler we drilled out some 3/4" holes in the top bar and machined some threaded plugs to fit down inside them. Yes we loose 3/4"of the cooling fins, but this way it is mounted clean with our space constraints.
As for the oil cooler I had to cut off that top bung to clear the radiator support. We welded it shut and drilled the mounting holes in the mounting brackets we welded on.
You can see the whole assembly as one bolt on unit.
