So I have made the side templates for the front air panels - they will need a little tweaking and so me brackets to hold things together but they are almost there. Then it’s just making up pieces to mate the top piece to the sides … … not much to look at but like.all little things, it takes time. I have also come up with a plan to mount the condenser as the original locations are no longer available. If will need a couple new hoses as well. My universal fan shroud came in and I think I have an idea to install it as well …. here’s the back/radiator side …. …and here is the engine side …. I will back mount the fan to the shroud and welding some aluminum rt angle pieces on each vertical side of the radiator, cut down the sides of the shroud to put the fan up to the radiator and bolt it up to the right angle pieces. Clear as mud I know but it’s a plan. I will need to find someone with a metal brake to make some bends in things but this is as good a stopping point as any. I keep banging away at it …..
You have AC right? Don’t further to make provisions for the lines to get past those side air deflectors.
Don't get the fan too close to the radiator core. You want fan to pull air through the entire core at slow speeds or stopped, not just the fan circumference.
The upper line isn’t a problem - it’s the lower one. I am working on a few ideas for that one. We shall see …..
Now I'm confused. With the fan mounted like that, isn't it going to***** air though all those holes in the shroud? The only source of air should be through the radiator. I get that they are for flow at speed. Probably why I've seen some with rubber flaps over the holes, for air to flow at speed but closed then stopped and the fan on. Otherwise, electric fans mount hard against the core. BTW, the cardboard ducting patterns look great.
I have seen the rubber flap ones too and I may just add them. I always kid around with my buddies about my “slice and dice” things I do and my templates are one of them! Lol!
Yeah, the flaps are supposed to be there for freeway speeds so the air can pass through and not be like driving a cardboard box aerodynamically. At low speed (where an electric fan does its thing) you want them closed so the air is focused through the core.
Just a quick note - the radiator is getting fitted for the new high speed 14” fan and generic shroud that’s almost the perfect size …..
Got about an hour in today on the truck and I worked on the added******* cooler. Originally I had it plumbed to the cooler, then the radiator, and back to the*******. I just didn’t care for having it plumbed through the rad via the comments here and my own thoughts on it. I tossed around a couple ideas but the one that made the most sense was to mount a second finned cooler under the first one behind the grill since there was plenty of room to do so. It will get plenty of air flow weather moving or stopped with all the air directed to the rad, the puller fan will keep things moving when stuck in traffic, and the******* lines are all ready run to the front. After enlarging the mount holes of the second, dual pass cooker, I mounted it underneath the first … I placed the inlet******* line to the top cooler and the return line from the bottom unit, connecting the two with a simple loop ….. Mischief managed as they say. We are getting there…..
Picked up the radiator/shroud/fan setup last night …. … and here’s the backside with bracing added to give it strength as the fan is mounted to the shroud, not the outside edges of the radiator ….. I am painting everything now ……
Getting it all painted up and looking for clips to hold the shroud in place ….. If I cannot find clips that will work, I may use SBC valve cover holddowns - have to measure one up and see ….. or make some up …..
I read that the last couple of outside rows on my Walker radiator do not carry coolant, so I sheet metal screwed my shroud to the outside of the radiator frame. It worked, and was done with the rad installed on my highboy.
Made some simple side pieces hold the shroud to the radiator….. Keep It Simple Stupid - fits me to a “T” ! lol!
Nice sheets - lol! Rad is now sitting in there with great clearance and n the backside - the fan hub is actually below the water pump pulley - tough to see in the pic …. We will see what else I can get done before my next trip …. The fan pulls great btw - let’s see what happens when the condenser is in front of the radiator ….. Btw - Koppy here on the HAMB cut down and welded up the shroud for me ….. thank you!
Worked a little bit on the top plate. I first had Thorton it down as the radiator is now further forward. I then made it slip under the lip of the top radiator tank to help keep the air pushing through the radiator….. However, this caused a slight bulge in the top plate that would not let me latch the hood securely. I need to do a bend in it so it sill stay “snug” on the one top crosspiece. I have it marked and I will bend it hopefully before I leave, if just to see this small part through ….
Well, I did not get the top cover bent up but I have the two side pieces and the bottom piece ready to cut out - with any luck that will be tomorrow, on the last day before I leave …..
It has been awhile but I am back at least for a little while …. I had transferred my templates to the sheet metal for the “air funnel” I am creating and I cut out the two side and bottom piece …. After debuting them a I installed the side pieces first …. Since this one wraps around the******* cooler hoses, I put sone door edge guard on the metal and taped them in place …. … and slipped both sides in …. The bottom piece needed two bends and not having a break I had to get creative…. … to bend the material with what I had around. The lower piece needed two bends …. … which didn’t turn out too bad since I “wag’d” the amount for the two bends. So far, not too bad …. But, I will have to modify my plan with the two side pieces a bit to keep things simple. The last two pieces I need to make up are the bottom connector from the side pieces to the bottom plate. This whole thing is not going to be “air tight” so how much of a fudge factor do I have with air actually passing “through” ? I imagine I will get about 90% of the air hitting the grille but how much will actually go through and at speed will depend on how many openings there are. The other 10% not hitting the rad will help me more than hurt me I think. While on my hiatus from the build I picked up sone “Italian” leather for the fan shroud flaps from Tuscany, Italy while on vacation there in Sept. I also found a pair of pouches that are perfect for .”loose stuff” in the cab area for the coupe and roadster. Pics to come on those …. Good to be back on the project …..
Well done! Necessity is the mother of invention. “That’s using your melon for something besides a hat rack” as they say over here in the mountains.
I think if you can get 90 percent air flow directed through the radiator that would be phenomenal! More than most and more than necessary. Mine won’t be that tight.
Both the concept and the execution seem to be right on. Can't wait for summer to give it a true test of cooling at extended highway speeds. Sounds like the shroud is nearing completion also, which will help cooling while idling. Good job.
