Is there a difference between a Supercharger and a Turbocharger? If so, could you please explain? Thanks

I'll tell you what I know, which is basically the jist of it.

Supercharger- They produce performance by having 2 screw like cylinders force more air into the engine. They are powered by a belt that actually turns the 2 screws. Thus creating your boost. However being belt drivin, They do make more power right away, but you sacrifice the use of some of your other options. Superchargers take away a little bit of power from your other engine components that need to be belt drivin as well.

Turbocharger- Turbochargers are powered by the exhaust, rather than a belt like superchargers are. The turbo is basically composed of 2 turbines. One turbine gets turned by the flow of exhaust trying to get out of the engine. The other compresses the air getting into the engine, which also forces it into your intake. However, because it relies on your exhaust pressure to spool up, it takes a while for it to actually give your engine more power. This period is called "Turbo lag". Now there is a way aroumnd turbo lag. You can have 2 turbos, one small, one larger. The smaller turbo spools up quicker giving you better power sooner, but leaves off your top end. This is where the big turbo would help. Once the first turbo reaches it's top end, the larger one spools up, and gives your car a faster top end.

In conclusion, both of these systems work generally the same. They both force air into your intake manifold to let your car get me air to breathe in. The only MAJOR difference is the way they're powered (Superchargers by belts, Turbochargers by exhaust pressure).

If someone finds something wrong with this info, please feel free to correct me. :thumbs:

Silly Inygknok, that would be too easy.

Besides, who cares? Satty apparently had enough time to explain it, and if nobody did, then we can just link it.

Yeah...mainly when we JUST got it running (Didnt run at all, had to replace about 1G worth of engine stuff, and the suspension) and then to hit a little dry spot, grab like crazy, flip on the roof, and have the seatbelt break...yeah. Im done mudding for a

remember one thing: all turbochargers are superchargers, but not all superchargers are turbos... :laughing:

Turbochargers are a class of superchargers, originally known as exhaust driven superchargers.

there are belt driven superchargers, gear driven superchargers, and exhaust driven superchargers (turbos). On the belt drive side, there are Roots style, vane type, and centrifugal type (which are essentially belt driven turbos in design, though decidedly not in operation). In each type, there are various subtypes.
