10 years ago, if Toyota said they were bringing a 12.5:1 compression engine to market, people would say "Impossible! It won't work on 91 octane!"
13:1 is out of the question... right? Then the Prius was released. Overseas, they get 14:1 with 93 octane. Blasphemy!
Then mazda pushed 16psi boost through an engine at 9.5:1 compression in the MZD. People realized over 20psi from stock turbo with tuning, all on 91 octane.
I don't think 8psi is out of the question here.
