With the TC4 I got my best temp without the stock turbulators installed using the Eheim 1250. Nikhsub1 also removed the stock turbulators and had better results. I then made the copper coils. Nikhsub1 is reporting 1c-1.5c better cooling with the coils installed over an open channel. I am still waiting for parts to do my testing. It's going to depend on what pump you are using whether you going to see a difference. We both use the 1250 high volume pump. The coils have not been tested using a smaller pump. Nikhsub1 did report that while using the stock turbulators his 1048 pump out performed the 1250 because the stock turbulators were causing to much restriction for the 1250 pump to shine. Currently with the coils the TC-4 using a 1250 pump is out performing any other arrangement with stock or open channels.
Updated photo of the newer coils using smaller wire and less coils.
