Frequently Asked Questions
What is a 2 stage nitrous plate and how does it work?
A 2 stage nitrous plate is an intake spacer that introduces nitrous oxide and fuel in two separate stages. The first stage typically engages at a lower RPM to provide a smooth power increase, and the second stage activates at a higher RPM for additional power. This progressive delivery reduces shock to the drivetrain and improves traction.
What should I look for when buying a 2 stage nitrous plate?
Key factors include maximum HP per stage, material (billet aluminum is preferred for durability), included components (solenoids, controller, gaskets), and compatibility with your intake manifold. Also consider safety features like blow-off provisions and ease of jet changes.
Do I need a progressive controller with a 2 stage plate?
While a progressive controller is not strictly required, it is highly recommended for smooth power delivery and to prevent engine damage. Many 2 stage plates include or are designed to work with progressive controllers. Without one, the stages engage abruptly, which can cause traction loss or drivetrain stress.
Can I install a 2 stage nitrous plate myself?
Installation is moderate and can be done by a DIY enthusiast with basic mechanical skills. It involves removing the intake, placing the plate with gaskets, and connecting fuel and nitrous lines. However, tuning the jetting and ensuring proper safety systems (like a blow-off valve) may require professional help, especially for high power levels.
Are 2 stage nitrous plates safe for my engine?
When installed and tuned correctly, they are safe. However, improper jetting, fuel delivery issues, or lack of safety features (like a window switch or fuel pressure safety switch) can cause engine damage. Always follow manufacturer guidelines and consider a professional tune.
