What is Turbocharging?
Turbocharging boosts engine power using exhaust gas. It spins a turbine, driving a compressor that forces more air into the engine. This allows the engine to burn more fuel and increase its power output.
Understanding the Mechanics of Forced Induction
Turbochargers force more air into engine cylinders. This increases the engine’s efficiency, allowing it to produce more power. Forced induction unlocks hidden potential in engines of all sizes.
Harnessing Exhaust Energy for Increased Power
Turbochargers use hot, high-pressure exhaust gas to spin a turbine. This turbine drives the compressor, recycling exhaust energy. This clever design gives turbochargers their impressive power-boosting abilities.
“Turbocharging is a game-changer, unlocking untapped potential in engines of all sizes.”
The Science Behind Boost Pressure
Boost pressure is measured in pounds per square inch (psi). It determines the extra power a turbocharger provides. At sea level, standard atmospheric pressure is about 14.7 psi.
A turbo providing 7 psi boost doubles the air the engine naturally aspirates. Higher boost pressure directly relates to more horsepower gains.
Measuring Power Gains in PSI
Twin turbo setups increase horsepower by 10%-13% over stock turbos. They can deliver over twice the air of single turbo setups. This is due to atmospheric pressure limits.
The DPS 62mm twin turbo runs at 78% efficiency below 2.3:1 ratio. It produces around 55-60 psi boost. At 40 psi boost, its efficiency as a single turbo drops to 70%.
A twin turbo kit at 58 psi boost produces air temps of about 375 degrees F. A stock turbo at 40 psi boost produces air temps of about 495 degrees F.
In compound turbo setups, 60 psi boost pressure results in 58-60 psi exhaust pressure. This leads to direct horsepower gains. The wastegate opens fully about 2/3 up the boost scale.
“Compound turbo systems in OEM diesel applications provide vehicle owners with response, power, and fuel economy.”
Single turbos see about a 1:1 ratio of exhaust to boost pressure. For example, 70 PSI exhaust pressure at 40 psi boost pressure.
Single big turbo Cummins may achieve nearly a 1:1 ratio. However, they suffer from significant turbo lag. This often leads customers to switch to compound turbo setups.
Intercooling: Keeping Cool for Maximum Output
Turbochargers force more air into engines, raising air temperature. This hotter air is less dense, reducing potential power gains. An intercooler cools compressed air before it reaches the engine, solving this issue.
Cooler, denser air boosts horsepower and prevents engine knock. Intercooling is crucial for maximizing power output in turbocharged engines. It helps avoid premature detonation, a common turbo engine problem.
Two main intercooler types exist: air-to-air and air-to-water. Air-to-air intercoolers are simpler, cheaper, and lighter. Air-to-water intercoolers provide denser air and fit in tight spaces.
Turbosmart, a leader in temperature management, specializes in intercooling and air cooling tech. Their boost controllers and blow-off valves are known for top performance and reliability.
