Full contact vs non contact crank scraper
There are two flavors of crankshaft scraper, the teflon full contact and the metal non contact.
My question; is there proof the full contact makes more power?
The fact that it touches the crank makes me think that the less expensive non contact version would be better. I know there is more work involved to trim and adjust it correctly.
I have not used them before. Any input would be most appreciated.

Having not used them either I personally dont think that anyone will see a signifigant difference in any application with a full contact vs non contact.
The extra percent or 2 of gain in the full contact in reduction of oils on the crank will only relate to the same few percent of the power gain from oils on the crank... which i would think would be minimal.

And I know crank scrapers are used on not just miatas but they're very rare here. I'm sure they're really common in the american muscle crowd.

I have one sitting in the garage for the 1.8 I'm building. I've touched it. That's about the extent of my experience. I did read the directions though. A touchless one sounded easy to install. The teflon scraper one sounded annoying and potentially dangerous to install and tweak. I'd personally go with a touchless one.

It's hours and hours of cut-fit-cut-fit to get it to just rub everything a little bit. It takes goddamn forever and I'm not convinced that it's worth it unless you're building a rules-restricted engine. Putting one on a street car is an exercise in idiocy.
