This Billet LT4 Supercharger Lid replaces the factory supercharger lid on GM LT4 Superchargers for a quick and clean install. The improved airflow design of the lid increases up to 25HP by itself and increases power even more when the water methanol injection system is activated.
The direct port water/methanol system comes complete with water/methanol solenoids, high pressure electric pump, stainless braided lines, pre-bent stainless steel hard lines, filtered nozzles, composite reservoir, a NX stage 2 digital progressive methanol controller, and all fittings necessary to complete installation.
We started NX in 1996 because we knew we could offer nitrous systems that outperformed anything on the market right out of the box. Nitrous Express had an advantage; we got to start with a blank sheet of paper. We were able to manufacture our components with all the hot rod modifications built in. This allowed our customers to achieve better results right out of the box than other racers who were paying big money to modify our competitors’ parts. It was like a breath of fresh air! We spent the next 22 years perfecting our nitrous products while expanding our product line to include some awesome NX nitrous and water methanol products.
