1969 Camaro Transforms From Big Block to Supercharged LT4 V8 at V8 Speed & Resto Shop

At this point, the decision was made to install the later version of the LT4 supercharger hat, which will accommodate water / methanol injection jets from Nitrous Express.

Water / Methanol injection is a great tool to reduce the intake charge temperature, allow for more aggressive ignition timing, and therefore increase the power output of the engine.

The system uses basically the same solenoid system as a nitrous oxide kit, but this time, it’s spraying a water / methanol blend under much lower pressure. A reservoir tank and pump are needed, as well as some form of controller to make it work.

Here, the jets are plumbed into the new hat and the solenoids are mounted. Nitrous Express provides this service, which came out great.
