Is it better to turbo or supercharge a 4 cylinder?
A turbocharger provides better fuel efficiency and reduces emission, but boosts power at a specific rpm resulting in turbo lag. A supercharger instantaneously boosts the engine’s power but results in more fuel consumption. That said, because superchargers do depend on the running engine to operate, it’s a less efficient process than a turbocharger. They are also, on the whole, more expensive than a turbocharger, but they’re also easier to install.The main disadvantage of a supercharger is that it steals energy from the engine in order to spin, making it less efficient. Can a car have both turbo and supercharger? A car can have an electric supercharger and a turbo installed. The supercharger produces low-RPM boost, then disengages when the turbo kicks in.When building an engine for supercharging (other than for racing), it is generally built for low to mid-range torque and power. This is similar to a stock engine. And because a stock engine can be used with a supercharger, it would be just as easy to operate or maintain. This makes it less exotic and more practical.
How much horsepower does a supercharger add to a 4 cylinder?
On average, adding a supercharger will give you a supercharged horsepower boost of about 46 percent with 31 percent more torque. That’s some neck-snapping gains! VF-Engineering chose to supercharge the Audi S4 4. Eaton TVS1900 supercharger. VF Engineers knew that only a roots type supercharger would give a torque increase needed to satisfy the hungriest enthusiast.The 2011 Audi S4 is powered by a supercharged 3. V6 that produces 333 horsepower and 325 pound-feet of torque. Power is routed through Audi’s AWD system, which features a torque split of 40 percent front/60 percent rear.The supercharger is one of the most critical components of your Audi S4’s engine. It increases the engine’s power output by forcing more air into the combustion chamber. Upgrading to a larger displacement supercharger can provide increased boost pressure, significantly improving acceleration and top-end power.
