Curious if there's any difference in oil pressure between the dual and single pass coolers? The dual would see a relatively squared off 180 as it goes from one pass to the other where single pass seems like it'd have a higher flowrate?
Cool stuff (no pun intended). But about the "black body radiation" thought that was a myth...?! Or is it when the car is stopped/no airflow situation. THANKS
Shiny metal surfaces have low emissivities both in the visible wavelengths of the electromagnetic spectrum and in the far infrared (Heat). Painting the surface black fixes that.
Of all people I'd say you Mike kojima are the guy is trust to get that chassis competitive or know from the beginning of its worth tweaking . @motion any reason in particular you chose that chassis and what exactly the purpose is for the car. I would love to know more about it. Suspension?
Rodney has a nice Daytona there

You are probably right but I never have seen this cause a problem. Seen plenty of cases when the oil getting too hot and causing a problem.
never thought i'd see aero and wind tunnels used for testing coolers. 👍
great video keep it up
i like dual pass

@@mikekojima9761 thank you sir!!
what Mike left out is that the black paint is an insulator and defeats the thermal conductivity of the radiator.... which is its sole job.
Is that a sentra @motoiq ?
You'd be surprised how many FWD SR20 powered cars we've had and currently have ;)
Ah yes, I remember the Disco Potato Sentra from the SCC days.

this plays like an advert...
Don't use an excellent oil cooler then.
