Okay... for Ben2k, Cathar, Jaydee and many others who have WAY more knowledge about this stuff than I do.
Below is the design. It shows 3 sizes of copper tube to use for the jets. The drawing shows the largest (1/8") used. This gives 30 jets and a flow area roughly 3 times that of the inlet tube.
Will this be okay? or should I use a smaller jet tube size and get more of them in there?
This is mainly just a test of the general design to go with my radiator that's on order. I want to change the block first, then the radiator and compare.
Thanks in advance everyone!
