Have you split open a oil filter?
I
As far as oil filters and bypassing, I like my motors to get clean oil, not with larger particle in it due to the filter bypassing 40% cold oil
How do you measure the bypass quantity?
Wix has stated that their race filters with internal bypass bypass 200 % more(40% vs,20% than the stock filters do, they have also stated that their stock bypass filter can bypass up to 20 % with cold oil at the lower air temps, below 40F.
No rumors or I think I heard kind of information from me!
Ok. You're not actually measuring, just using supplier literature. So the literature is saying that the valve is twice as big, so it can theoretically bypass twice as much. But in reality, it will only bypass the amount needed to control/balance the pressure differential dictated by the bypass relief. You will not actually know if, when, or how much oil is bypassed. Arguably, another good reason to not use a high volume oil pump and high viscosity oil.
