Is it better to turbo or supercharge a V8?
While modern turbo technology has narrowed the gap, there remains a perceivable lag as the turbo spools up. In contrast, superchargers, which are directly driven by the engine’s crankshaft, provide instantaneous power. This immediate throttle response has endeared superchargers to drivers of performance V8s. However, they can experience “turbo lag. Superchargers are directly connected to the engine’s crankshaft, delivering an immediate power boost of 30% to 50% without lag. However, this comes at the cost of lower fuel efficiency.Supercharging is less commonly used in the 21st century, as manufacturers have shifted to turbochargers to reduce fuel consumption and increase power outputs, especially with reduced engine displacements.Disadvantages of Superchargers Being connected to the crankshaft, Superchargers use some of the engine’s power to operate themselves. This means the overall power output may be lower on supercharged cars as compared to turbocharged cars. The kinetic energy of exhaust gases isn’t utilized in superchargers.Upgrading your car’s engine with superchargers or turbochargers puts additional stress on its components, so it’s crucial that everything is in good working order to handle the extra power.
How much HP will a supercharger add?
Q. How much power do the superchargers and turbochargers increase in an engine? A supercharger can increase an engine’s power by 50 to 100 horsepower. On the other hand, a turbocharger can increase an engine’s power by 70 to 150 horsepower. 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.Supercharger Disadvantages The disadvantages of a supercharger include: Increased gas loading on the engine. Higher heat loss due to increased turbulence.Although roots superchargers have significant parasitic load and do dramatically decrease fuel economy, centrifugal superchargers (like ProCharger) will yield approximately the same fuel economy as normally aspirated engines under normal throttle conditions.Adding a supercharger to an engine can greatly reduce its reliability. The added stress on the engine internals can put more wear on the engine in a shorter amount of time. However, if the engine is supercharged from the factory, it could last longer since it’s under the OEM manufacturer’s specifications.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!
Is it cheaper to turbo or supercharger?
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. Benefits of Supercharging Unlike turbochargers, which may experience a slight delay due to turbo lag, superchargers provide an immediate boost, resulting in quick throttle response and rapid acceleration.Although roots superchargers have significant parasitic load and do dramatically decrease fuel economy, centrifugal superchargers (like ProCharger) will yield approximately the same fuel economy as normally aspirated engines under normal throttle conditions.The design of a supercharger, which pulls its power from the engine, actually hurts efficiency by adding to the engine’s load. That typically shows up in lower fuel economy averages.Choosing a supercharger vs turbocharger the turbocharger powers the engine more slowly and at higher rpms, but it adds strength while using less fuel. Superchargers are easier to bolt on directly, while turbochargers require work on the exhaust and intake.This could increase the wear on the engine components and result in premature failure. Adding a supercharger to an engine that wasn’t designed to run with forced induction could affect its reliability, as the internal components were not built to handle the additional stress such a modification would throw at it.
What is the biggest downside to a supercharger?
Supercharger Disadvantages. The biggest disadvantage of superchargers is also their defining characteristic: Because the crankshaft drives them, they must steal some of the engine’s horsepower. A supercharger can consume as much as 20 percent of an engine’s total power output. Turbochargers make better horsepower, but superchargers are better for low end torque. Depending on what you are trying to do, your choice might change.So, a supercharger provides an instant boost, while a turbo has boost lag and has to spool up before delivering power. The downside of a turbo is that you don’t get that instant boost, but it’s more efficient than a supercharger. The supercharger has to use power from the engine, which will use more fuel.Next, the supercharger compresses the air which increases the air’s pressure and density. This way the engine receives more air through the same intake, which allows it to burn more fuel resulting in a boost in performance. However, that boost comes at an upfront cost. Notably, a loss of horsepower of as much as 20%.Supercharger or turbocharger A turbocharger works with the exhaust system and can potentially give you gains of 70-150 horsepower. A supercharger is connected directly to the engine intake and could provide an extra 50-100 horsepower.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.
