Pressure drop across turbo filter???? Ideas & Opinions

[jd94ss]

Hey guy's. I was wondering if a few of the experts would chime in and help me with a question that I have. I started working on my own turbo saver from some parts I had bought for another car and never used.
Well here is what I am trying to figure out.
I am running an ACDELCO PF1218 oil filter that has anti-drainback (heres some info)AC-Delco - PF1218 Oil Filter (PF1218) for my turbo saver on a new TE-60 that I just bought. Now my question is, being the size of the filter and possible pressure drop across the filter; should I run a -4 or -6 line from the feed block to the filter inlet. I plan on running -4 back to the turbo inlet. Theres a diagram below of it 1/2 way mocked just for your guys advice and input. The only other thing I was thinking of was tee-ing in a gauge and watching its pressure as I drive; in comparison to -4 & -6.
Here is the pic. Please any info would be great as to what size line I should run etc... etc... etc...
Thanks for your time, and for looking.

good ? I just asked the same thing about using different size lines to feed the turbo and if there were any draw backs. I trying to make my own pre/post luber set up with a electric pump

Thanks 86 Nick. One of the reasons I ask -4 or -6 for supply, just due to the fact that I have read from other member on here -6 and up to the turbo (pending application) will blow by and smoke due to increased pressure. I would most likely run -4 from the filter to the turbo to avoid that. But I am still undecided as far as what to run from the oil feed block to the remote filter???

If you think about it, the size of the hole in the brass block the oil feeds out of is about 1/4 anyway for the inverted flare fitting on the stock oil feed line so a -4 should be fine as you are already restricted in the brass block to 1/4"

I run a 4an line with and in line filter and I only see about a 1/2 lb pressure drop across it so I imagine you will see roughly a 1lb loss across the larger filter you will be running. A 1lb drop will not hurt it.

Where did you get the filter mount? Do you have a part #? I might do something like this down the road.

He's right, the brass block wound limit your flow anyway. Unless you remove block and go right off the engine block.

Thank 87 WE2,
I had received the remote filter mount awhile at a local car show/swap meet. I can check the part number for you when I get home. I was doing some research in my old college hydraulics books, and according to pascals law it should work fine. As you were stating, being that the brass block is a 1/4 feed, running a -6 to feed is not neccasary. I also ended up find out after some free time, that the remote filter will also accept a PF-2232,1218,61, and a 46 as well; being that there are the same thread size and pitch.

I think I am going to leave the brass block in. With there being different possibilities filter wise now; I think that with a larger filter having a lower micron rate than a smaller filter there would be a "less" pressure drop across the two as opposed to running a smaller filter with a higher micron rating which would have "more" of a pressure drop. I will let you know when I am all said and done. I have two gauges that I plann on running to check and see what the delta is between the in and out by trying various filter sizes.

Also any other ideas or suggestions are appreciated and welcomed.
Thanks again.
