Does anyone have a good definition for both these terms and how and why they work? What advantages do they have? Can a car be both turboed and supercharged?
just for my own and others future reference.

thanks guys

move this if you have to

 

Nope you got it in the right place. In simple:

Turbo runs forced air induction off of exhaust.
Supercharger runs forced air induction off of a pulley.


Turbo you can run hella high boost on some cars (not xB).
Turbo can make cars quick as ____.

Supercharger can too though. Supercharger cant really run as much boost though on a daily driver really.

You can do both. It's called twincharging. It's not really plausible with xB.

Supercharger gets up power fast and in the begginning. Turbo has a "lag" to it, but has better potential IMO.


Others can probabaly explain this better. I'm not very good at this stuff.

Hope it gives ya an idea though!

no, believe me, i have no desire to do any of the above to my box, just wondering, when i drive by a car that says twin turbo supercharged death car, what it means

 

Superchargers use the motors serpentine belt to turn, forcing air into the manifold...either by screw type, or by centrifugal (looks like a turbo)
->Upside - makes good power gains, and minimal boost lag
->Downside - uses motors power to turn - robs HP

Turbochargers use exhaust gas to turn the turbo, and then forces air into the intake.

->Upside - Doesn't rob the motor of power, since it is using exhaust gas. So it is more effecient. Generally has more significant power gains
->Downside - A lot of plumbing and cost (although not ALWAYS more expensive) significant lag since the turbo needs to SPOOL

I have seen a car turbo'd and supercharged....I'll try to find it online...

 

oh, and if that doesn't make sense...this is a good place to look....

YEAH, THIS CAR IS PRETTY MUCH INSANE!

 

is that a dual-charged vega? awesome.

 

turbocharging is actually a form of supercharging.

 

it's all technically the same...it's like a casio watch uses batteries to run, a rolex uses springs n sh*t...they both tell the time, one just works better, and one costs more money...they are both forced air induction, in that way...YES turbocharging is a form of supercharging...

 

But the trubo charger robs HP also. There must be considerable backpressure to make intake pressure. Also there is the problem of turbo charger bearing heat. Both during operation and after the engine is shut down. Post shutdown oil circulation is desirable but another complication. I do not see the practical side of either charger method for routine traffic situations. Just something else to go wrong.

 

what kind of car is that

and how does both of them quite work out together??? its all cornfusing to me that goes right over my head

 

so a turbo on an xb would ultimately hook up to the intake manifold where the engine meets the stock intake in the front of the engine bay??

intresting stuff, guys, thanks for the info, learning a lot here.

 

This is a really horrible drawing.

 

I believe it is an australian chevrolet ( holden ) or a euro ford. very hard to tell


as far as turbo and super. well the turbos come first sucking in the air , compressing it then forcing it to the carbs . the compressed air flows thru the carbs whilst being blown into the motor via the supercharger. with this setup there is normally lag because the supercharger starts pulling air before the turbos have pushed it there.

oh and since the intercooler ( also called an aftercooler ) would just make the lag even worse it is not used. irl if someone were to street this they would barely get power cuz the air would be sooo hot. this car would be a dyno and drag strip queen. it would only perform well at low temps and for short intervals.
