If any sort of automotive race engine is built without coatings nowadays, its considered cutting corners and being cheap. Almost all of the companies in the coating industry use TechLine coatings, and they have many DIY products if so inclined.

This is the only scientific test that I'm aware of: http://www.hotrod.com/techarticles/e...s/viewall.html
