Can you supercharge a fuel injected engine?

Supercharging with booster pump: If boost pressure exceeds 10psi, adding a booster pump to a 60lb fuel injection system is a popular option. Acting like a boost-reference regulator, as boost intensifies, the booster pump generates more fuel pressure and flow. Higher voltage spins the pump faster.

Can a 454 be fuel injected?

But in 1988, Chevrolet introduced Throttle Body Fuel Injection to the 454. It was the same TBI system used on small-block V-8s and the V-6s. Fuel efficiency increased and the TBI system remained until 1995.

Can you turbo a fuel injected engine?

After-treatment can be easily achieved without too expensive systems and applications of this combustion mode on current naturally aspirated engines show high volumetric efficiency and compression ratio in comparison with intake port injection. …

How many MPG does a carbureted 454 get?

The 454 is a big-block carbureted engine found in most older model Chevrolet cars and trucks. The engine uses eight cylinders to provide high-end torque and speeds. The combination of larger bore and eight cylinders equates to very poor gas mileage. The engine runs an average of 10 to 15 mpg.
