Dual Oil Filter Question
 

could i run a second oil filter on my 88 non turbo convertible, or would that drop the oil pressure to much? I have a idea for a setup using a relocation kit and some other things

Set them up to run in parallel to reduce pressure drop.

Is there a benefit to running two oil filters? I've never heard of it before...

cleaner oil???

Personally, my oil gets filled with gas far before it gets dirty. :dunno:

Putting two in parallel would cut pressure drop compared to a single one. The dual relocating mount also lets you run much larger ones than stock. I can't think of any benefit to running them in series, only drawbacks.

Would running them in parallel be negated by the hose and fittings required to install the adapter?

Might be. I think most people use the filter elimination block and then plumb them inline with the oil cooler lines, so you're not adding much length if you do it right.

Depends how you plumb it. Avoid 90 degree fittings, and it will give a significantly lower pressure drop across the system. To do it optimally, you'd want to plug the lower iron fitting all together, and replace the stock filter with an adaptor plate. You can use the adaptor plate to form a 'Y' so that the stock pressure regulator still functions.

The is a RACE car modifcation used for 2 reasons: lower pressure drop through thr oiling system, and larger filter media.

I think it's a waste of time.
I haven't seen evidence of oil lubrication problems due to bad filtration in any engines torn down when using a good, quality oil filter and oil.
Adding all that plumbing just adds complexity to the system and now the possibility of more oil leaks and failures.

Why not just go with a bigger oil filter?
There's a replacement filter that's like twice the height of the stock oil filter - from a 929? (don't quote me on that) - that does the same thing in a much simpler solution.

I don't know how you can add all that extra stuff when a 13B turbo with a single turbo upgrade with an FMIC tasks up a LOT of space!
Add aftermarket coils and you get nil space to add a double, remote oil filter set-up...
Where were you planning on putting these things???

Filters are far more restrictive than bends. Even ignoring that, a small increase in tube diameter will dramatically reduce restriction. Then you could do loop-d-loops if you felt like it and still be fine. Conversely, any place where the diameter decreases is of far more concern than measly bends but still probably less restrictive than a filter.

I'd agree that there doesn't seem like much point to this and a leak or burst from a plumbing mistake could cost you your engine. If you really want insanely clean oil, look up bypass filters. But engine wear on a standard filter & oil is already so low that you wouldn't notice the difference except maybe after 400,000-500,000+ miles.

you'll kill your engine from a gazillion other things besides slightly dirty oil, especially if you actually change it at regular intervals.
