Bought a BMW PS reservoir with a send and return.
Cut off the return and plugged it

I plan to run a line from the IC bleed valve to the return on the BMW tank. But I have some questions:
1) Is my return nipple too low? does it matter?
2) Tank has a vented cap. Any issues there?
3) Think I should have tapped the tank and installed a 1/4" barb instead? (or whatever size the bleed port is). That way, I wouldn't have to use a reducer from 1/2" to 1/4"

typically the return line should be above the fluid level in the reservoir so it will be self bleeding.
in a traditional split the reservoir is only used as a filling point.

I did this , did not chop anything on the reservoir connected straight to it from underneath , just used a barb reducer on the bleed pipe from the supercharger

Alright. I had some time today and mocked it up.
Tapped the tank with a 5/16 barb and used a 90* 5/16 heater hose. Fits good. Nice and clean.

I have the reservoir where the inlet/outlet thingies are slanted at the bottom, so I didn't have to modify anything. On the bleed nipple of the supercharger outlet, I cut a small piece of fuel line that had a 1/2" outer diameter and forced it on to that nipple so I could use 1/2" hose to the tank.
Oh, and that vented cap? Whenever I would do a long pull, like 3rd gear, water would shoot out of that hole. I watched it squirt out like a water gun when it was on the dyno. I plugged it from the inside, so now I get a little bit of leaking at the cap after a long run.

I split my IC system on my SL55 a few days ago, and after I drove it about 20 miles on a 90 degree afternoon, coolant was squirting out that little hole in my BMW reservoir cap. Coolant went everywhere, the fan blew it all over my engine bay, it was a huge mess. I thought I was the only one having that issues, but I guess not.

Don't know how the SL55 is setup, but it might have the bleed system connected to the engine cooling system expansion tank. If so when the engine cooling system pressurizes it will flow into your split intercooler system and cause it to over fill and blow out.
If yours is setup that way you will need to disconnect the two systems completely including the bleed purge hose.

Looks awesome. How much capacity does it hold? Does it have a radiator cap to handle pressure blowoff? As long as the cooling loop is not connected to engine radiator lines, it's golden. Hooking up the bleed port allows it to self bleed (and move/mix the reservior coolant, and allows cooling loop to better burp up air).

Thanks guys. Tank holds 1 and a half quarts, or 48 ounces. Cap is a 6 pound radiator cap with a Billet Specialties machined cover. This works well with my Bosch 010 pump. I have since made another tank which is getting black anodized, and the cap for this one is a black notched 16lb. cap from Billet. This should work with the SLS Pierburg CWA 100.2 I will be installing soon. I have more pics.

BRH AMG has the right idea, if this piece is in line with system coolant pressure of at least the 16lb then gluing or bonding onto a plastic BMW tank is asking for trouble, with this pressure when you try to contain it by blocking the vent port the pressure will find the next weakest link which will be the glued on port or threaded brass piece. To have the car puke the coolant out when the fitting fails will not be a good day. "Use Caution" when designing a piece of equipment that must contain heat and pressure, just like you never remove the rad cap from a hot car, we all know what will happen then right!

How much of a need is there to have a self-bleeding system? Once the system is filled and bled after a pump or H/E install, why would air get introduced into the system?
