Here's why:
* High Compression Ratio: 11:1 is a relatively high compression ratio for a naturally aspirated engine. Adding forced induction (a supercharger) drastically increases the pressure inside the cylinders. This will lead to extremely high cylinder pressures during combustion, far exceeding the design limits of the engine's components. This will likely result in detonation (pre-ignition), leading to broken pistons, cracked cylinder heads, and potentially catastrophic engine failure.
* High-Performance Cam: A high-performance camshaft is usually designed for optimal performance with naturally aspirated engines at their normal pressures. A supercharger will change the intake dynamics, making the cam's profile potentially less efficient and further contributing to detonation.
To make this work, you would need extensive modifications, including but not limited to:
* Lower Compression Ratio: You'd likely need to replace the pistons with ones designed for forced induction, resulting in a significantly lower compression ratio (around 8:1 or 9:1 is typical).
* Forged Internal Components: Forged connecting rods and crankshaft are essential to handle the increased stress. Stock parts will likely fail.
* Improved Cooling System: A much more efficient cooling system will be necessary to prevent overheating. This often means upgraded radiator, water pump, and potentially an oil cooler.
* Fuel System Upgrades: You'll need a much larger fuel pump, fuel injectors, and potentially a fuel management system (e.g., programmable fuel controller) to deliver the increased amount of fuel required.
* Ignition System Upgrades: A more advanced ignition system may be needed to manage detonation, possibly with adjustable timing.
* Proper Tuning: Professional tuning on a dyno is absolutely crucial to ensure proper air/fuel mixture, ignition timing, and boost pressure.
In short, while it might *seem* possible, attempting to simply bolt a supercharger onto that engine is a recipe for disaster. The cost and effort of making the necessary modifications would likely exceed the value of the vehicle unless it's a very high-value classic you're restoring with no regard to expense. It's far more practical and safer to either build a completely new engine for forced induction or choose a different, more suitable engine for your supercharger project.
