Re: Rear Mounted Oil Cooler
Quote:
Thanks for the input Hib. I've been doing some more research and here's a few things I discovered. The factory oil cooler is quite large and has a total of about 15 feet of .78in OD piping.... 6 rows of horizonal pipes are bracketed by the in and out vertical pipes. I'm not sure how that stacks up pressure wise when compared to say a 15 foot straight run. I talked to tech at Derale and was told that the factory system is not a very efficient design by todays standards. It may be possible that a smaller but more efficient cooler combined with a longer hose run may not be all that different in pressure. Probably need a fluid dynamics engineer and testing to know for sure. As far as point 2 goes my understanding of the system is that the cooler bypass line is temperature activated... therefore on start-up the cooler line is effectively bypassed thus it should have no effect on engine oil pressure at that time. If you have information to the contrary I'd like to see it. Routing a cooler off a remote oil filter line on a big block would be a whole different ball game as it sounds like oil would flow through the cooler 100% of the time. Weight of about 20ft of line would be 3-5lbs dry depending on the size and type of line... but a smaller aluminum cooler should be lighter than the stock one. Fluid weight would depend on the capacity of the new cooler and added lines vs the stock system... I don't think its really feasible to drop overall weight, probably a wash at best. The main benefit would be moving weight rearward.
