That's a good point. I didn't think about any pressure drop between the block outlet and the radiator. PSI-G .vs PSI-T
It's probably still have to be pretty high in the radiator though. If there's 80psi in the block at almost 300F and you blow that down to 20 or so, I'd imagine that's cause some pretty violent flash boiling in the radiator. Violent enough to destroy it, I would imagine.
When I got my car, it came with a new radiator. Now I want to see if I can find a part number or any kind of pressure rating data on it.
EDIT: Now I'm thinking if a uber high pressure NECKCAR radiator is a thing, that might be the hot ticket for the guys that think you have a $1M radiator to keep a TR cool at idle when you're at a light making 10hp.
I can see it now..... 'super trick earlbrown high pressure radiator that can hold 80PSI'... comes with a free 'cool guy' sticker.. lol
