Here is a youTube of the Roush Intercooler Reservoir in action:
If you go by what RedLine states for mix (about 3-4 caps per quart), with the speed of these pumps, it creates a lot of foam -- I found 2 caps total is just about the amount to use in this setup -- these varimax pumps MOVE the liquid fast so I want to avoid cavitation. I may go back to a 90/10 mix just for added protection. Right now, I change the coolant a couple of times a year, so I don't expect any major issues. BTW, RedLine suggests changing once a year -- I'm sure there is a reason for that.
I figured how to build my mount so that is the next item on the list.. Right now, its stable while I'm testing, but would not want to wait too long to build that one ;o)...
