It's very appropriate that the nozzles at the heart of the Nitrous Express Shark SX2 nozzle nitrous systems look like the business end of one of the big booster rockets in Russia's space program, because the SX2 systems deliver power big-time--up to 1,200 hp, in fact! Perhaps more importantly, though, since they're actually designed to be two-stage nozzles, you can feed the power in all at once or in two distinct increases, whichever suits your setup better. On top of that, you only have to drill half as many holes to install a full set, and there's only one nozzle in each intake runner, which means less turbulence to ruin the airflow.
