| Sounds like you are missing some of the fundamentals. Read the article posted by BEASTT below. boost and compression ratio both contribute to cylinder temperature and pressure. advanced ignition timing, Cylinder temperature, and pressure contribute to detonation and pre-ignition. This is not a wild or new theory. This is not interesting. It was well known by nissan in 1989 when they gave the TT lower compression from the factory for better performance under boost using pump gas. it doesn't really have much to do with energy utilized by the turbos, although a small turbo choking off the exhaust will also increase cylinder temps.
1. Nobody is surprised that this high compression setup works great on e85. e85 is extremely detonation resistant. It allows you to run for more advanced ignition timing and boost than regular gas. This is old news.
2. This same high compression build is also putting out monster power at high boost on 91 octane gas. This part is the amazing part. Most setups would not be able to achieve this without detonation causing catastrophic mechanical failure. The current theory as I understand it is that HUGE aggressive cams + HUGE turbos along with lots of head work is the secret sauce that makes this possible. Remember that a medium sized turbo and a large size turbo both making 25 PSI the medium turbo will likely be outside its optimum efficiency range, and while it is able to push 25 psi, the charge will be hotter and cause more back pressure than the larger turbo pushing the same 25 psi.
