How does this bypass system handle acids that build up in a gas engine . I see most are used on Diesel engines .
I remember reading a similar remote oil system but that one had a heater in it to remove contaminants but this doesn't have that .

so hold up, apart from trying this oil bypass system (which we are all curious about)
your saying if i run LESS oil in my sump i will gain more power?, and a considerable amount as well....
do you guys want me to dyno this theory or not??

It's true if "full" on the dipstick is at a level that causes windage.
Engines can be run 1 qt low for a reduction in windage which in theory should free up HP and fe, and it is safe too, as long as you don't let the oil level get too low. "Add" on the dipstick is not too low.

The eccentric shaft is essentially the crank shaft. 2 strokes and rotary's burn oil for lubrication, but both have huge problems with emissions.

Water and oil don't mix.

I suggest removing the oil to increase MPG, the oil pump robs a lot of engine power. If you use those additives you don't need an oil pump, they show them on TV were they drain out the oil, and the engine still runs great.
This should help MPG a lot.

Sigh..

btw there car makes about 470ishkw so yeah

I see the confusion here.
Dry sump does not mean they have drained the oil. It means there is not an oil pan full of oil under the engine. It is a constantly recirculating system with an external circuit, cooler, filter, etc.

With regard to the oil bypass filtration system suggested by the OP I can say its a good cost saver in the long run for larger engines running on expensive synthetics. My LPg powered 3.2 litre Jaguar XJ6 used to have an TF Purefiner 1 micron filtration system that I fitted and it would run on Amsoil synthetic oil for approx 30k miles before a change was required.
The issue with running the oil for the life of the vehicle is that the contaminants in the oil are not just particles of metals and dirt etc, they are also acids that will corrode away bearings and even water, soot and other chemicals that can cause demege if allowed to build up.
The biggest indicator is the oil's Total Base Number (TBN). Its best to change the oil when the TBN reaches 50% of its original value (new, unused oil). This requires oil samples to be monitored at regular intervals and of course involves some cost.... but as it also reports on the condition of the engine (much like a blood test for us) its valuable in spotting problems before they become serious :-)
So, on my Jag the cost of oil was £50 per fill, and with an oil change being specified at 10k mile intervals it would have cost £150 for those 30k miles. Instead it cost me the £50 plus 2 oil sample tests @ £13 each, so £76 instead of £150. Half the cost!
The kit cost £215 tho so you can work out how many miles before payback :-o
