BEST ENGINE PERFORMANCE UPGRADE – TURBOCHARGER VS SUPERCHARGER VS NA?

image

If you own a standard engine for example Proton Campro iafm, cps or vvt, and plan to upgrade the performance of your engine, this question must be playing in your mind before deciding which route do you choose. To upgrade as a Naturally Aspirated (NA), to bolt on turbo or to fit in supercharger?

NA engine =

+ without force induction
+ playing with replacement of engine internal and external part to performance part
+ engine more reliable but without fine tune, it also can blow
+ quick response and no lag
– need more money and more expensive parts to achieve better horsepower
– need more time to upgrade all parts
– you will never satisfy with the power achieved and what you upgraded. A lot of NA parts out there for you to try.

Supercharger Engine =

+ Most easiest way to get super fast pickup from 0-100kmh acceleration
+ Easy Plug and play without disturbing exhaust system
+ Immediate response with minimal lag.
+ Power achieved at low RPM and gives better fuel consumption with relax driving style.
– Need to have Engine management to minimize engine overheat
– Need to take care the belting and mechanical parts. Hard maintenance.
– More expensive than turbo but power achieved is lesser than turbo.

Turbocharger Engine =
+ Most powerful engine upgrade with best horsepower achieved
+ Cheapest cost to have better horsepower.
+ Easy bolt on with less time consumed.
+ Can be tuned and managed by Engine management to prevent engine blown.
+ Fuel consumption can be reduced with smaller engine capacity or changing gear ratio.
– Engine check light comes up without management.
– Power limited by engine strength and reliability.
– Need frequent maintenance and inspection on the turbo kit and oil system.
– Need to control boost and watch engine temperature.
– Has turbo lag with bigger turbo. Minimized by using smaller turbine, VGT system or twin turbo.

Some description og Turbocharger VS Naturally Aspirated engine :

A turbine-driven forced induction device that increases an engine’s efficiency and power by forcing extra air into the combustion chamber. This improvement over a naturally aspirated engine’s output results because the turbine can force more air, and proportionately more fuel, into the combustion chamber than atmospheric pressure alone.

Turbochargers were originally known as turbosuperchargers when all forced induction devices were classified as superchargers. Nowadays the term “supercharger” is usually applied to only mechanically driven forced induction devices. The key difference between a turbocharger and a conventional supercharger is that the latter is mechanically driven by the engine, often through a belt connected to the crankshaft, whereas a turbocharger is powered by a turbine driven by the engine’s exhaust gas. Compared to a mechanically driven supercharger, turbochargers tend to be more efficient, but less responsive. Twincharger refers to an engine with both a supercharger and a turbocharger.

Turbochargers are commonly used on truck, car, train, aircraft, and construction equipment engines. They are most often used with Otto cycle and Diesel cycle internal combustion engines. They have also been found useful in automotive fuel cells

Naturally Aspirated Engine

In a naturally aspirated engine, air for combustion (diesel cycle in a diesel engine, or specific types of Otto cycle in gasoline engines – namely gasoline direct injection), or an air/fuel mixture (traditional Otto cycle petrol engines) is drawn into the engines cylinders by atmospheric pressure acting against a partial vacuum that occurs as the piston travels downwards toward bottom dead centre during the intake stroke.

Owing to innate restriction in the engine’s inlet tract which includes the intake manifold, a small pressure drop occurs as air is drawn in, resulting in a volumetric efficiency of less than 100 percent – and a less than complete air charge in the cylinder. The density of the air charge, and therefore the engine’s maximum theoretical power output, in addition to being influenced by induction system restriction, is also affected by engine speed and atmospheric pressure, the latter which decreases as the operating altitude increases.

This is in contrast to a forced induction engine, in which a mechanically driven supercharger, or an exhaust-driven turbocharger is employed to facilitate in increasing the mass of intake air beyond what could be produced by atmospheric pressure alone.
