I'm making an intercooler out of 3 cores.

Should the tanks slope down to the end or be even? What size should the tanks be for good flow?

It seems like most of the major manufaturers slope them down toward the end.

I would just make the tanks slightly larger than the OD of the piping to be used, but that is once again just based off of what I have seen.

Yes, give them a slight taper, perhaps 10*

I would say the diameter should be regulated by inlet size. Start at the inlet/outlet size (in height of the endtank, obvisouly a bit taller than the actual inlet/outlet size) So if you're using 2.5" pipes start there and then work your way down from there in accordance to the taper you use. That's what I would do at least.

I think the absolute ideal is inlet/outlet at opposite ends, but that's getting really picky.

I agree. Air is always going to take the easiest path to its outlet, so if your inlet/outlet is on the same end, its going to resist going to the opposite end of the intercooler, so you'll get heat soaked quicker on the inlet/outlet end. If you have them on opposite ends, any path through the intercooler is the same distance/resistance, so you'll get better flow. BUT... then you're dealling with alot more installation issues.

http://www.are.com.au/feat/techtalk/intecoolersMR.htm A great read for intercoolers. Taught me everything I know. :eyebrows:

Also what material will you be using? If you're using aluminum I hope you can tig weld yourself. If not it will more than likely cost more to build it than buying a good NPR or Mishimoto intercooler.

I have a friend Tig welding it up for me.
