Sean's RCR GT40 build

I’m still on the fence with the eyebrows. I have a set but not sure if I really like how they look. Unfortunately they don’t cover the area of the door that’s rubbing. I’m debating something that ties into the roll bar to hold the doors in place as I have seen others do.

The part that hits is the corner where it starts to transition from the roof to the side of the car. Both sides hit in the same spot pointed out in the picture
Your project is coming together nicely. I have had the same issue during my mockup fit. I have not tried to tackle that problem yet, (it's really a slight amount of rub) My thought was to adjust the door slightly higher than the spider (just enough to clear the spider) and then have the final adjustment in the latch and striker to tie the alignment together. It should work in theory. Also take as much material off the inside edge of the corner of the door as you can. I hope to be working on my fitment sometime next week, I will keep you posted.

I was able to get a lot done the last few days. Welded out the roll cage, got the spider, doors, and front clip sprayed with high build primer. I’m glad to see all the body lines are still were they need to be with only minimal effort to realign. The car is definitely looking good now that it’s all one color. I feel like I’m finally getting to the downhill side of this build.

She also got her first Carwash yesterday, just over 2 years of dust and filth had it looking pretty bad.

Going to leave the front clip off for a bit to make some radiator modifications. Going to move the passenger side piping to the bottom to help clear the nostrils. I also plan to install a bung on the top to have a line attached to help keep the air bleed out of the system.

I’m getting a little better with the aluminum welding. Got the pipe moved to the bottom of the radiator. This definitely got things cleaned up in the front. I will have no issues with the modifications I want to make on the nostrils now. I will plan to make a line to come out of the top of the radiator to help keep the air bled out of it while the car is running.

Isnt that an aweful flow, NOT to have diagonal flow accross entire radiator. But to only have flow accross the bottom?

Good observation, I might be wrong in my thinking. But my thoughts are that the flow of the pump should cause a pressure drop between the 2 tanks across the fins. If so, it should flow throughout the entire radiator. As of now it seems to be heating the entire radiator and cooling the engine well. Although it is only 50 deg outside today.

I'm with Darius on this one Sean, For an air bleed just tap and install a petcock or an old style rad drain near the top of of one of the end tanks and add a hose.

I think you're good Sean.

Under very low flow, you may have most of the flow through the bottom, but when the pump is moving water, there will be a pressure differential across the core that will cause flow across the whole radiator.

That moment you realize you just built the mold for your new dual nostril setup backwards….. Guess I’ll be taking this apart to make it the right way tomorrow :rolleyes:

One step forward, two steps back. Know it all too well.
On a positive note you are making amazing headway on your build. And it is turning out awesome!

After making the mold the correct way, I was able to get the dual snorkel completed. I made it using plexiglass, this allowed me to make an identical mold on the other side by flipping each pice and using the same screw holes.

Got the single nostril lined out as well. The main issue with it was they didn’t lay enough glass on it to keep it straight. I ended up putting 4 layers of glass on it to help it hold its shape.

Got everything sanded down and primered so that I can start blocking it. Car is definitely coming together now. I really like how the dual nostril turned out and it should get all the air from the radiator out of the front end.

Very nice work Sean… I had both hood panels for my car as well. I glassed in an aluminum tube to “split” the air between left and right nostrils and to strengthen them.

Thanks Randy.

I took a good bit of inspiration from your nostril setup. I really liked how you set it up. I wanted to make mine more rounded like yours, but I didn’t have the room behind the fans to make it work and keep the look I was going for by extending the original openings and keeping the same angles.

I am still trying to figure out how this radiator is going to effectively cool with out being a dual pass design? Now I am questioning my Serck original style radiator and wondering what is it's flow path??

So I had a brain fart... My tank is divided at the bottom, flows bottom up due to the baffle in the middle of the bottom tank, then down to the
right side.
