A stock 4.8 engine can typically handle a maximum boost of around 6-8 psi safely. Boost refers to the increase of air pressure in the intake manifold of an engine, which can significantly increase power.
It’s important to know the limits of your stock engine, as too much boost can cause damage to the internals. The stock 4. 8 engine, commonly found in trucks and SUVs, is not built to handle excessive amounts of boost due to its design and components.
While it can handle moderate levels, going beyond the recommended range can result in engine failure or other issues. Before adding any forced induction system like a turbocharger or supercharger, it’s crucial to assess the engine’s capabilities and consider any necessary upgrades to support higher boost levels. This will help ensure a reliable and efficient performance without compromising the longevity of the engine.
