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.

Alcohol pump:




The new hat didn’t match our desired color scheme, so it was cleaned, scuffed, and masked for some new color.



First color is a charcoal gray found in various accents on the car, like the window trim and door handles.



Then the fins were masked and the second color was applied, a bright and vivid red.







After unmasking, the fins were stripped and the ribs were returned to a natural aluminum finish.



The end result looks factory clean and custom tailored to the car. We also tuned up the LT4 badging and gray on the coolant hoses.

Looking good!
