How Much Boost Can A Stock 5.7 Hemi Handle

How Much Boost Can A Stock 5.7 Hemi Handle

A 5.7-liter HEMI engine can handle a considerable amount of boost depending on the modifications and tuning done to it. 

Generally, a stock 5.7 HEMI is capable of handling up to 10 psi (pounds per square inch) of boost without any major modifications or parts upgrades being necessary as long as the appropriate fuel and supporting components are used with the engine. 

However, if the engine has forged internals, it may be able to handle more boost. Additional modifications such as upgraded internals like stronger rods and pistons may be recommended in order to safely support higher levels of boost pressure (15-20psi).

The stock 5.7-liter Hemi V8 engine can produce up to 395 horsepower and 410 lb-ft of torque, making it one of the most powerful engines from the factory. With this much power and torque potential, a stock 5.7 Hemi can handle up to 8 psi or 635 horsepower without any major modifications or tuning.

This makes for an easy and reliable boost that won’t push your engine too far past its limits while still providing a significant increase in performance over the already impressive base output numbers.
