NOTE: If you have a Stage 1 kit and not a Stage 1R with upgraded injectors you will need to upgrade injectors. Click here for that Power Pack.
Superchargers are nothing more than air pumps. They pump air into the engine, which allows you to inject more fuel, and that means a bigger “boom” when the mixture ignites and more power. On paper, no drawbacks. In reality, driving the blower and compressing air is not a very efficient process, and it generates heat. Heat is the enemy of any combustion engine, and even more so when you add boost. If the incoming air into the engine is too hot, it can cause the air/fuel mixture to ignite early, which is referred to as “detonation” or “knock”. This is the killer of engines, especially stock engines.
You can further reduce blower discharge heat by allowing the blower to breathe more efficiently. If the air can enter the blower easier and with less restriction, the blower uses less force/energy to pull that air in and in-turn less energy to compress it before discharging it. The best way to do that is to reduce the restrictions on the inlet of the blower as much as possible. This is where the Stage 2 upgrade comes in from going from a tiny 90mm throttle body to a MASSIVE 132 mm throttle body.
