@ koniu777 Cześć!
Unfortunately, the core and the rest of rad is made from alu. Also, the tubes in rad aren't connected serially to each other, so flow goes first through half of them, and then through the second half. Only good news are that this makes no restriction at all, and here all benefits ends
I don't know yet if I'll modify the rad.
Thank's all You Guys for your interest in my build.
Will update soon !
You might end up with some nasty corrosion if you mix copper with aluminium.
