I am looking into using a normally open (fail safe) solenoid valve in-line with the water/oil cooler lines, and replacing the lines with flexible reinforced hose, since it looks like the stock hose/tubing assembly being stiff is contributing to stressing the connections. I will be adding some type of sleeve over the tubing where the sway bar can make contact, too. Maybe a section of Teflon tubing? I work in the semiconductor industry and we use tons of high-end valves and some of my co-workers are great resources for fluid systems and can help me find something that is not crazy expensive and still reliable. I can easily make the electrical controls, either an automatic one with a temp sensor or switch that will fail safe (valve open) or a simple remote toggle switch with a timer and buzzer to remind you. Once I get that system proven out in the spring I will post up the details and parts list for those we want to build it on their own, and maybe put together some kits for those who just want a plug and play kit.
Some info that would be helpful to me:
1. What is the typical/max PSI seen by radiator hoses running at redline?
2. What is the design of the radiator lower hose manifold inside. Is the fluid path through he oil cooler in parallel with the radiator lower hose or is all of the fluid forced through the cooler. I am guessing in parallel since the cooler hoses are smaller, but want to be sure. If it is in series then I need to do a cooler bypass instead of a cut-off. I won't be able to look at mine till spring. I know a few of you have one laying around. Pictures would be great!
3. What would be the optimum temp range for the oil? If I chose to get fancy, I can use a Watlow PID temperature controller and a proportional valve to hold the temp steady (hey, I'm and EE, I like to play
). If the cooler is even capable of cooling too much. Maybe in winter it could, but for those running in winter I doubt the cooler is required and should just be disabled.
Any help would be much appreciated! Once I get some info collected I will start a build thread so anyone with more info or suggestions can chime in. I don't pretend to know everything and appreciate constructive feedback.
