question about split cooling modification
I have been reading conflicting information here. I'm upgrading my cooling system in preparation for boost modifications. I have already installed the 010 Bosch pump and have the PLM HE ready to go in. I found fabtech makes a kit with a BMW power steering reservoir. I have been seeing people say it's not needed because the T fitting does not allow the engine coolant to mix with Supercharger cooling. What is the final verdict? Do I need to split cooling or don't bother.
Thank you in advance.

You only need to split the cooling loops if you plan on running a different fluid on the H/X side, or if you plan on using a tank to store cold water. Otherwise the H/X and engine radiator do share fluid, but there is minimal-to-no heat transfer between the two since the reservoir is the only common part of the two loops.

Good basic information that everyone here should know but surprisingly I don't believe is common knowledge in this forum. Cheers Joe.

We being one of the newest readers to the forums there is a lot of information to digest. Also, it's not always clear what the agreed upon answer is by the community without separating the topic and asking a pointed leading question to get an objective answer instead of subjective comment.

Splitting the cooling loop will yield better results. It's not dramatic, but it is there (and since it's cheap and simple to split the loop, why not).
It makes sense since, because even though the coolant in the intercooler does not directly mix with the engine coolant, it still flows past a T barb connected to engine coolant, so some heat transfer does occur.

By the way, the BMW reservoir is vented to open air, it does not allow the coolant loop to pressurize, and coolant sprays out under heavy coolant flow. Previously I sealed my reservoir up and installed a grease pressure valve fitting, but that only last so long before the valve wears out.
I'm also about to install a much better solution that allows the loop to pressurize, won't spray coolant, and it should look factory'ish. I'll post photos when it's done.

I'm wondering myself? I just bought a data logging software/hardware to log my car stock VS after modifications.

ive done this mod on my sl55 but noticed even with a new pump minimal coolant circulation and now im bout to install on my s55 and aside from drilling and tapping a fitting to the highest spot on the bmw tank for the bled line was curious about pressurizing the system and what affects that would have on IATs . When I followed instructions last time it had me only using the center male port on the res and capping off the other and due to not wanting to stray to far from the instructions declined to connect that bleed line that goes back to the oem expansion tank to an additional fitting on the highest past of the tank which would then allow the units to self bleed . Unlike many others I keep the level at 1/2 way point and have yet to have any actual coolant leave the res
