What is the diff between the two and which one is better for a daily driver who just wants the extra hp.

 

A blower is a supercharger.

 

Opps

 

Self-ownage is funny

 

I bet that you're wondering what the difference is between a blower (supercharger) and a turbocharger maybe? They both do the same thing; they force air into the induction system of the engine. The difference is of how they are powered to do what they do. A supercharger is driven by a belt, like is obvious on Funny Cars and the turbocharger is powered by exhaust gases. Turbochargers require more maintenance to keep motor tuned correctly, they also need an oil supply for lubrication that is fed from the engine oil supply. Sometimes turbochargers are referred to as blowers as well, but they're never referred to a superchargers. They have that unique whine; like a turbine engine or jet sound.

 

C'mon now, play nice

 

The question is what type of FORCE INDUCTION you want.

 

Now I know about supercharger vs turbo. Can someone explain the dif between carbs and fuel injection? Is F I "naturally aspirated?
Thanks"

 

Any induction system that isn't pressurized is "Naturally Aspirated." All that means is the engine 'breathes' air at normal atmospheric pressure.

Both carbureted and fuel injected systems can be either naturally aspirated and both can be pressurized. They can be pressurized either by a supercharger or a turbocharger. The pressurization allows more oxygen to be forced into the combustion chamber to develop more power per piston stroke. These days most engines use fuel injection because it is far more precise and can give better emission control, more power and better drivability than a carburetor.

All C6 engines so far are naturally aspirated and fuel injected. The ZR1 will be supercharged. That's the best choice in my view for a sports car. The reason is the power boost is linear. The faster the engine runs, the more pressure can be developed. With a turbocharger, the boost lags as engine revs build. That's not a good thing for powering smoothly out of turns.

I hope this clears up some of the mystery for you.

 

Thanks for your help.

 

Ok.lets start with the last part of the question first.Naturally aspirated simply means that there is no form of forced induction i.e.blower or turbocharger or ram-air to the intake of the motor,purely atmospheric pressure which is approx 14 p.s.i.This is the weight of the air on our planet.the second part of your question "is fuel injection normally aspirated",yes,on most domestic vehicles (diesel motors not included) use normally aspirated motors,however certain vehicles use fuel injected systems which are either blown or turbocharged i.e cobolt ss blown, buick grand national which was turbocharged.Difference between carb and fuel injection.Here goes,a carburetor draws air through its body or barrels,(hence the terms two or four barrel) at which point the fuel, which is also connected to the carburetor is drawn into the air-stream using a principle called the venturi effect,atomized together and sent on its way into the intake manifold and then drawn into each cylinder in turn.Fuel pressure is around 5-7 p.s.i.In a fuel injection system the air alone is drawn into the intake manifold,there the fuel is introduced by injectors,which are under high pressure created by the fuel pump,about 60 p.s.i.The injectors are basically an electrically controlled valve which is opened and closed by the computer for varying lengths of time.The time opened is based the load and conditions of the engine.Hope this helps. bob.t

 

 

Were you refering the difference between Root and Centrifugal type blower/supercharger?

 

 

FWIW, you can also increase engine power without resorting to forced induction. In fact, some people feel that a naturally aspirated engine is preferable.

 

Moving to C6FI

 

i've always heard it's better to be "blown" than injected.......

 

I used to feel the same way untill I found that at altitude FI does better then non FI

 

Thanks everyoneI'm less dumb than before. Iam amazed by the level of knowledge amung te Forum folks.

I love my car.....injected and blown
