Dimpling, otherwise called Ribblets. Rilbbets were used on Americas Cup to help win the race. 3 M developed the film that was applied to the bottom of the boat. VERY secret kind of stuff, highly mathematical and very promising if done correctly. Sharks utilize this to help the fluid dynamics of their skins. Yes NASCAR tries to utilize it in their head and intake designs. Would REALLY love to know what is working and what isn't.

Nothing to do with compression, at all, nada. But fluid dynamics and stuffing more charge into the cylinder, a way big thing. Maybe as much as 25% MORE CHARGE ie POWER. I have seen as much as 5% improvement with kids just messing around, porting and divoting without knowledge. Given some KNOWLEDGE and the right kind of divots, just like a golf ball, huge improvements can be had. Unfortunately the "correct" skin might be more like the grooves in a record. They would, unfortunately, get colgged up right away. But who knows, maybe there is a compromise that will do some good.

Unfortunately only world class mathmaticians can even understand the basics of this technology, by world class, I mean something like 5 or 6 out of the entire world, maybe less.

Judging by the past responses to my statement that the engine is a PULSED system, more like less.If you understand stepped and corregated waveguide, and are very very comfortable with all its design aspects, you just might be able to tackle this problem. I mean Greens theorm, Maxwells equations and Shrodingers wave equations, mixed with Fourier series are just like ohms law, simple, straight forward two year old math, a love of cars and engines, and the willingness to dedicate 5 or 10 years to the solution of this problem.
