PROS OF SUPERCHARGERS:

No Lag

A supercharger has no lag and consistent power delivery. Power delivery is instantaneous because the supercharger is driven by the engine’s crankshaft.

Increased Horsepower

Adding a supercharger is a quick way to boost power to any engine.

Low RPM Boost

Superchargers provide good power at a low RPM in comparison to a turbocharger.

Low Price

Superchargers are a cost effective way of increasing horsepower.

CONS OF SUPERCHARGERS:

Less efficient:

the biggest disadvantage of superchargers is that they suck engine power simply to produce engine power. They’re run off an engine belt connected to the crankshaft, so you’re essentially powering an air pump with another air pump. Because of this, superchargers are significantly less efficient than turbochargers.

Reliability:

with all forced induction systems (including turbochargers), the engine internals will be exposed to higher pressures and temperatures, which will of course affect the longevity of the engine. It’s best to build the engine from the bottom up to handle these pressures, rather than relying on stock internals.

PROS OF TURBOCHARGERS

Significant increase in horsepower.

Power vs size:

allows for smaller engine displacements to produce much more power relative to their size.

Better fuel economy:

smaller engines use less fuel to idle, and have less rotational and reciprocating mass, which improves fuel economy.

Higher efficiency:

turbochargers run off energy that is typically lost in naturally-aspirated and supercharged engines (exhaust gases), thus the recovery of this energy improves the overall efficiency of the engine.

CONS OF TURBOCHARGERS

Turbo lag:

turbochargers, especially large turbochargers, take time to spool up and provide useful boost.

Boost threshold:

for traditional turbochargers, they are often sized for a certain RPM range where the exhaust gas flow is adequate to provide additional boost for the engine. They typically do not operate across as wide an RPM range as superchargers.

Power surge:

in some turbocharger applications, especially with larger turbos, reaching the boost threshold can provide an almost instantaneous surge in power, which could compromise tyre traction or cause some instability of the car.

Oil requirement:

turbochargers get very hot and often tap into the engine’s oil supply. This calls for additional plumbing, and is more demanding on the engine oil. Superchargers typically do not require engine oil lubrication.
