Just added a second oil cooler...

But they are two "conventionaly" sized coolers so I'm not sure how large the Jackson water/oil is by comparison, and how that might alter things.

Can we assume you are running a stock OEM oil pump?

Yep, stock.

I held back because this is your thread and not sure if you felt the discussion was going off into the weeds.

Gear pump is a positive-displacement device. Without the bypass valve, it would pump the same volume until downstream pressure increased to the point of breaking the weakest link in the circuit. Think hydro-lock. Something's going to let go, maybe the pump itself. Word on the street is the bypass (safety) valve opens at 140 psi, so no worries there.

Adding a second oil cooler in parallel actually lowers the head loss. Think about the same flow rate going through a fatter pipe. It slows down. In your case, the only significant restrictions are those banjo fittings. I'm not a fan but, as proven in your pressure measurements, they're just fine.

I remember when I first sprung pictures of my setup. People harped all over it. "Oh no! It's going to blow up!" SMH... You're golden as long as you don't eat any rocks.

%100 about the banjo fitting!! that one drives me internally nuts... but I'm a bit stuck becasue I need the clearance it provides (to the air filter) and I cant find a high flow version that matches the thread on the sandwich plate yet. So I try to console myself thats its 10AN into an 8AN line.

Everything's a compromise. I love your work!

UMMMMM
Wonder what the fuss was about

300 psi gauge is legit. I don't see a problem.
