what's the diffence between a turbo charger and a super charger?

Question

And which one adds more horse power?

And which one adds more horse power?
And which is better for your car?

Answer 1

They both serve the same primary purpose: to get more air into the engine on each stroke of the piston. They just use different methods of compressing the air. The amount of air that gets into the engine is one of the main factors that determines the power it makes, so increasing the amount of air by pressurizing it is a quick way to increase the power output of an engine. Turbocharging and supercharging are two ways of accomplishing this.

A turbocharger uses the pressure of the exhaust stream to spin a small fan, called an impeller, which is connected to a compressor fan in the intake tract. The compressor fan does what its name indicates: compresses air in the intake, so that there is more oxygen in each piston's stroke than there would be if it were just being drawn in normally.

A supercharger uses a mechanical connection -- typically a drive belt, though there have been superchargers that used chains, gears and even oil pressure -- to drive its compressor. The principle is the same: compressing the intake air allows the engine to take in more oxygen on each stroke of the piston.

From a how-it-feels perspective, turbocharged cars tend to have a slight delay between stepping on the gas and having the car's full power be delivered. This effect, called turbo lag, stems from many factors, but primarily arises because the turbine impeller makes only a very small increase in pressure for each revolution, so it takes a lot of revolutions per minute to cause a significant rise in pressure.

Supercharged cars, on the other hand, have a direct connection between engine speed and pressure, so they tend to have "snappier" throttle response. However, because the connection is "always on," supercharged cars tend to have a higher loss of fuel efficiency than turbocharged cars, because at a constant, low speed (such as freeway cruising in high gear) the turbocharger is consuming very little power. This is changing as computerized engine controls optimize the car's fuel delivery for the best balance between performance and economy -- and also as turbocharged vehicles benefit from engineering advances which reduce turbo lag.

Answer 2

You do NOT have a whole lot of choice! There were ONLY turbo charged Mitsubishi engine available. Many times, you can do a full engine swap with a turbo engine. Turbo engines are very interesting because the extra power is just WAITING to be used. When the engine is idling or holding a contstant speed, the turbo spools just sit there and wait until called upon. This is like FREE energy. Audi, Ford, Mercedes, Saab, and other car companies have pioneered the turbo charger use. Supercharging requires EXTRA internal strength. The new AUdi engine is supercharged, and so are some Mercedes engines. The bottom ends must be strengthened to handle the extra forces generated by belt driven forced induction. GOOD LUCK!

Answer 3

The turbo charger is powered by the engine exhaust. The exhaust gases spin a turbine which is connected by a shaft to a compressor that forces air into the piston chamber. The super charger does the same thing except the shaft power comes from the crankshaft via drive belt. The turbo charger has a slight delay with sudden acceleration because the exhaust gases need a moment to increase in pressure, where as the super charger has a faster response time since it is mechanically powered by the engine.

Answer 4

Turbo systems are cheaper to maintain,usually. Centrifugal superchargers are a little bit less than somthing that is top mounted like a grassroots, or a paxton. Also you can put turbos on just about anything, 4,6,8,10,12 cylinders it does't matter. If you try to put a supercharger on a four cylinder it would have to be something like a procharger and you would probably destroy your engine unless you really knew what your were doing. Think busted headbolts from all of the excess pressure, or atleast blown headgaskets every other day.

Answer 5

A turbocharger is "powered" by the exhaust gas generated by running your engine while a supercharger is "powered" by a belt that it attached to your engine, very much like an accessory such as your air conditioning. Both work on the same principle that when either spins up it can compress the air and allow you to increase the amount of both air and fuel for combustion.

Answer 6

Turbocharger Vs Supercharger

The feuding sides of the turbo charger vs. supercharger issue may never come to an agreement over which is better. You'll get good boost with either choice, but there are advantages here and there. The folks at Squires Turbo Systems have worked long and hard to prove that a remote-mounted turbo system is the best of all worlds.

Since 2003, when STS roared onto the high performance scene, we've been tipping the scales in favor of turbo, and remote-mounted turbo, in particular. Compared with the belts and pulley system of super chargers, which use power from your engine in order to "gain" you power, turbo chargers are better. Using flow and otherwise wasted energy off your tailpipe, turbo chargers actually increase your gas mileage, rather than knock it down.

The arguments against turbo usually deal with the tremendous heat that they generate under the hood. Not so with the STS remote-mounted turbo system. Bolted onto factory mounts under your car, truck, or SUV, the STS system gives you approximately 500-degree cooler turbo temps, not to mention better weight transfer and no additional lag.

Take it from the "Turbo God," Kenny Duttweiler, who tested the STS system and said, "Squires Turbo Systems' remote-mounted turbos have solved all of the problems associated with traditional engine-mounted turbo systems. The intense underhood heat a turbo generates has been eliminated." So get your bigger boost, increased torque, less heat, better mileage, and of course a monster sound to turn heads, with the STS remote-mounted turbo system.

Answer 7

A superchager works from a pulley on the engine. The Turbo charger works from the exhaust. The turnocharger does not consume any of the engine's horsepower.

Answer 8

turbo works from exhaust and super works from belt

Answer 9

The names. They both use the same principal to boost the performance of your car.
