We took some 1.5” aluminum to start fabrication on the radiator hard lines.
We marked up the angles that we needed to make the radiator lines and started fabricating.
The upper radiator hose is pretty simple with a 90* bend and a shallow ~35* transition to get the angle right into the Raceonly AST Delete.
We then rolled a bead to each end of the line.
With both ends beaded, we were ready to finish weld the line.
The radiator lines were finish welded by Mario of TSR Fabrications.

Fantastic update and all the custom work on the cooling system is so cool to read about. I am patiently waiting to see this thing finally unleash some HP!
Technically, you should have a ‘blade’ that bifurcates upper, and lower flows at the start of the duct. If you modeled this in CFD, there would be obvious turbulence that could easily be avoided.
Cheers.
Was about to comment the same thing.
Also, the air out of the IC needs to go somewhere… I don’t remember what the hood looks like for this project, but a proper vent with gurney flap and ducting would do wonders at speed.
Can’t wait to read the next articles.
It’s not that crucial to bifurcate the ducting. Many morern OEM cars don’t separate the inlet ducting of a common duct/plenum that feeds multiple heat exchangers because airflow is not laminar in the ducting and the important aspect here is creating a pressure differential across the heat exchangers. Proper ducting that seals the air from the front bumper to the heat exchanger creates a high pressure area on the front side of heat exchangers in the V-mount setup (or “L”-mount in many OEM applications) when using a common plenum (or air box, or radiator ducting).
I am currently in my FD build and would love to have one of these radiators, could y’all please guide me in the right direction to purchase one if they are available. I left a message on the BJR site to no avail. HELP…..someone??
