The Hellcat lid nitrous and water/methanol Stage 2.5 kit pairs a billet supercharger lid with a VC-50 progressive controller for proportional injection based on boost pressure. The controller displays boost and injection percentage and the kit uses an OEM-approved water/methanol pump and methanol-resistant components to cool and densify the induction charge, allowing higher effective octane and improved drivability across boost ranges.
