octane boosters?

An old trick that is seeing a lot of resurgance (especially with the high boost turbo crowd), is water or water/alcohol injection. It clean & cools the chamber, pistons and valves adn fights detonation. It really does work. I have an old-school Edelbrock injector kit to go into my resto-rod, 10.7:1 compression 440. Check out the offerings on eBay under "water injection" .
