* Lower power potential: V6 engines generally have less inherent potential for high horsepower than V8s. While you can add a supercharger, the gains won't be as dramatic. The V6's smaller displacement and often less robust internals limit how much boost you can safely add.
* Component availability: Finding supercharger kits specifically designed for a Firebird V6 is much harder than finding kits for the V8. You might need to adapt parts or even build a custom setup, adding significant complexity and cost.
* Engine stress: Boosting a V6 puts considerable stress on its components, potentially leading to premature wear and tear on the internals (pistons, connecting rods, crankshaft). These parts may not be as robustly built to handle the increased power as those in a V8 designed for higher output. You'll likely need upgrades beyond just the supercharger itself.
* Tuning complexity: Properly tuning a supercharged V6 requires specialized knowledge and equipment. You'll need to adjust fuel delivery, ignition timing, and other parameters carefully to avoid damaging the engine or experiencing poor performance. A poorly tuned supercharged engine is a recipe for disaster.
* Cost effectiveness: The cost of a supercharger kit, installation, necessary supporting modifications (e.g., upgraded fuel system, cooling system, stronger internals), and professional tuning can easily exceed the value increase in the car, especially considering the relatively modest power gains compared to a V8.
In short, while not impossible, supercharging a Pontiac Firebird V6 is a challenging and expensive undertaking with potentially limited rewards compared to the effort and cost involved. It's generally more practical and cost-effective to modify a V8 Firebird or choose a different project altogether.
