Difference between supercharge and turbocharge

[Acemundo]

Hi guys,

 

Any idea what is the difference between these 2? Read that VW's new version of golf is the first car that will combine both technology.

Supercharger is a belt driven compressor. Turbocharger is an exhaust driven compressor.

got pics to share? a bit difficult to visualise.

 

or got url on such write up to share?

Mark Wan's Autozine's technology page will provide answers. This combination of SC and TC has been done before on the Lancia Delta S4. The car is so powerful and so evil, it killed 4 drivers on the Group B Rally series.

okie, i do a search on mark wan and autozine.

 

haha.then the article said the wrong thing leh, that the golf is the first to combine both technology.

[Genie47]

The combination of both SC and TC for FI purposes is damn dangerous and very difficult to tune. The S4 caught fire easily and was also very powerful. SC for the low end and TC for the high end. The SC turns off when the TC comes on.

o i c, so each got their own speciality.

 

wah so despite this, the golf with this technology shld still be greeted with caution.

[Genie47]

But you must know the S4 then was from the 80s. It is now the new century with new electronics. Golf's FI mating could be good. We will see.

ha ha....dangerous...what if the SC is not cut off before the TC kick in due some electronics/machancis going crazy...car explode ??

[Acemundo]

why will simultanoues operation of tc & sc result in explosion?

[Genie47]

This is the said evil car.

 

 

Engine is in the rear.

 

[Acemundo]

so the rear is the supercharging part? the front is the turbo charging part?

[Seaweed]

humm...because the boost may be too high for the engine to take...just my humble opinion....ha ha ha...

[Linus]

u talking abt the golf's FSI engine ?

[Elfenstar]

You forgot the Nissan Micra Super Turbo. That was a mass production cars in the early 90's that ran fine on the dual setup.

 

Ace>> can u refer us to tha article... maybe they finally made a combined SCer and TCer in one.

[Acemundo]

which article? got url link?

[Acemundo]

nope, not the fsi.

 

think it is called the golf F1 if i didn't rem wrongly.

[Genie47]

Yes the Micra Super Turbo. Pretty good. An oddity in the world of forced induction.
