Are NAPA 7011 oil filters really that bad?

I don't know these engines at all so keep this in mind but is this a full flow, or bypass filtration system? Utilizing a restrictive filter to maintain oil pressure in the engine? I've never heard of that in the past. Though years prove me wrong, this reads of a design destined to failure without strict adherence to filter selection unless it is a bypass type system rather than full flow. I have several engines utilizing bypass systems only and they work well so find this interesting. I don't patronize my local Napa parts store but that is a business relationship and pricing is just the start of it.

I've long envisioned turbocharging my old wind up West Bend bedside alarm clock but I'm afraid that one hasn't quite gotten off the drawing board as of yet. Can't seem to find proper packaging to allow a workable fitment with thermodynamics considered. This on top of of space constraints, cannot for the life of me figure how to fit charge air cooling to the unit as I've had the thing so long as a passdown from my grandparents, I'd sure hate to melt it down, yet I'd still like a bit more performance.

Any engine takes to turbocharging like a duck to water if it is set up correctly. Got to control the heat, contain the pressure, absorb the inherent torsional stresses induced, and direct the power to a usable output to make it work. Easier said than done with engineering, manufacturing, marketing, and management involved in the mix. 

I had a 1989 Dodge Spirit car purchased as a bank repo to use as a loaner in the shop. Very clean little car with a blown head gasket but ran well. It was turbocharged but not intercooled. I pulled the head finding it cracked and ordered a new one from an aftermarket supplier along with an updated "graphite" head gasket. Installed new timing belt and water pump at the same time along with new hoses and drove that car to just shy of 400K on the clock with no trouble other than an air conditioning compressor going bad from age. It never did get used as a loaner my wife liked it so much. It really "woke up" after installing a "Mopar Performance" ecm, and Borla exhaust too without being very loud. Had a great tone, but not annoying.

Never did use oil between 5K oil changes but rust put it down as wasn't safe to drive any longer.   

I did try something for the heck of it. I decided to add a little zinc additive to the oil, and I also threw a little Marvel's in the gas tank and crankcase.  It literally cured my blue smoke issue on high throttle out in the field, and the oil pressure is better.  Normally my grandpa can see blue smoke out of the exhaust pipe if I am way out in the field, and the dark trees provide a backdrop otherwise the blue tint is hard to see.

After running it hard for about 2 hours it didn't use a drop of oil. Normally I see at least a 1/2 quart down.
