This concentrated octane booster is legal for all types of competition and contains no metal compounds like lead, manganese, or phosphorus. It easily mixes with gasoline, as well as alcohol and nitro blends. By adjusting the burn rate and raising the auto-ignition temperature of the air/fuel mixture, it effectively suppresses detonation and pre-ignition. When used with gasoline, it eliminates "pinging" and "knocking," preventing potential engine damage. This allows for higher compression ratios, resulting in increased horsepower.
