1928-1929 Ford "Janus" Edition
28-29FT Janus 6RT 11FT
When our customer Mr. Hansen requested a dual core for his 1930 model A e.g. dimpled 6 fin per inch face with a 11 fin per inch on the engine we all said "oooooh, now there's a twist. " So it will look stock in front and maximize the cooling on the back. We named it for the Roman God, Janus, for the future of engineering design and the reflective past of historic design.
He drove to Texas in the record setting heatwave of 2023 and had no problems so he requested the same for his 28-29 Model A so he can trek to Michigan next summer.
It is still a drop in replacement for the 1928-1929 Ford car or car based pick-up truck and set-up for the OE engine in its production year bu we hand shear a 1-1/16" round tube core with 6 fin per inch in the front and an 11 fin per inch flat tube core in the back. Then we hand punch the round tube headers and run the flat side in the dies
The highly elliptical tube shape provide equal volumetric throughput but increase surface area by 293% thus requiring fewer tubes and still providing greater heat exchange. Other features include a deep drawn tank with an OE stamp pattern, electric wire tabs, galvanized steel sidewalls, and riveted brackets for a longer life.
Features of the 1928 and 1929 Model A and Model AA radiators include:
- Traditional 6 fins per inch round tube core in the front half
- Modern efficient copper core design in the rear with 11 fins per inch
- Louvers embossed between each fin to disrupt air flow and facilitate heat transfer
- 3/4" seamless weld tubes in a staggered array to disrupt airflow laterally
- Die stamped three piece brass top tanks with model correct die stampings
- Galvanized steel sidewalls to resist rust
- Sidewalls available with relief like OE (upon request)
- Cowl rod bracket for support rods to firewall
- Internal baffle in top tank to prevent coolant loss
- Correct angle on lower outlet to clear power house generators
- Electric wire tabs soldered to lower tank
- Hood mount tabs soldered to top tank
- Painted flat black to aid in heat exchange
Made in the USA
Use of aftermarket stay rods (often in chrome or stainless) will cause your radiator to tilt forward and result in hood-to-shell separation.
