Hello everyone,
Sorry if im behind the times or if this questions been brought up before, but i did a fair amount of searching beforehand. Ive been wanting to run a two tank wvo system in my project truck before i even bought my donor. It probably will be another few months before my project is underway, but until then im trying to plan out my setup as i have over the past several months. First off I live in Florida and at the moment only commute 10 miles (15-45min drive with traffic) each way. I also do a lot of 'unneccessary' driving sometimes 20 miles, sometimes 60mi+. Im trying to design an efficient two tank wvo system that could heat the oil up quickly, and possibly remain hot for a while with the engine off. Now for the barrage of questions (sorry)...
1) Do most two tank wvo systems operate in an open or closed loop when underway (the wvo side)? Ive seen a few schematics, but dont know what can/cant be done or what the norm is. It just seems rather inefficient to heat the wvo up to ~150 degrees only to loop it back into a large volume of cold wvo in the tank (the tank also seems to be uninsulated in a lot of builds).
2) How long does it take most engines to reach operating temps to where the wvo is at optimal viscosity? Is this with a hose-in-hose setup, a heat transfer block, or both?
3) I was thinking of using aluminum hard line for most of my wvo supply line and coiling ~1-2 feet it of it densely and tightly around my exhaust pipe, and insulating it (perhaps with some foil backed fiberglass insulation?) why is this not done more? It should get way hotter way faster than the coolant, and should maintain its high temperature indefinatly given the flow rate/temp of the exhaust gases vs wvo flow/losses to the surrounding air.
4) Finally, the stupidest question for last, can you overheat the wvo/ does the wvo begin to degrade or do something undesireable much past 160F?
Sorry again for all of the questions, ive had them floating around in my head, some since August, and havnt found sufficient answers on my own. Thanks for the advice/knowledge/replies!
