few question..?

Question

what's the different turbocharge and supercharge??which one more powerful and which one more cost less?

Answer 1

A supercharger is a mechanically driven compressor which forces air into the engine. There are two types:
Roots, which is only 20% (so it heats up the air more than it compresses it) efficient but gives positive boost from just above idle to full RPM.
Centrifugal, only gives good boost at close to full RPM but it more efficient (80%). Higher levels of boost are available with this type.

The problem with superchargers is they provide more boost the faster they turn, so to prevent overboost, they only produce max boost at max RPM. The boost of the centrifugal superchager increases exponentialy with RPM so at low RPM it is producing very little boost.

Solution: Turbocharger
A turbocharger is a centrifugal supercharger driven by a turbine which is turned by the engine exhaust. A waste gate controls how much exhaust gasses pass over the turbine and how much bypass it. So theoretically we could have max boost at any engine RPM.
But... the turbocharger doesn't spool up as fast as we sometimes want it to (this is to prevent overboost) and it creates backpressure in the engine. This is called 'turbo lag'.

Turbos give you the most power across the RPM range but cost the most.

Centrifugal superchargers give as much power as turbos but only at max RPM.

Root superchargers are the cheapest, and have consistant boost across most of the RPM range, but give the least boost. But they cost the least.

Answer 2

A turbo is spun by exhaust, a supercharger spins off a belt from the engine. They are both expensive and can both make similar hp. Turbo may be a bit tougher because of exhaust mods. A turbo robs the engine of less power. A supercharger is felt immediately Where as turbo takes a little time to kick in(although newer technology and proper tuning have closed this gap a bit). I'd pick the supercharger. I was a diesel mechanic and i saw too many turbo failures. Things can get pretty messy when something is glowing red hot and spinning at 100,000 rpm!

Answer 3

The difference between a turbocharger and a supercharger is that a turbo works off the expansion of heat from your exhaust and a supercharger is on a belt like your alternator or water pump.

A turbo does not rob any power from your vehicle to make power, since the supercharger is on a belt, you have to take power to get power.

A supercharger makes power as soon as you hit the throttle, while a turbo spools up and starts making power between 1700-2500 RPMs, this is called turbo lag, can be annoying sometimes, but it will shoot you into the back of your seat.

As for power, depends on what you get but they make around the same amount of power and neither of them are too cheap. A supercharger setup and a turbo setup will cost you roughly the same amount.

Answer 4

Power cost$ money do not scrimp when power is your goal. Most turbo and supercharger cars start with forged low compression pistons did you think of budgeting engine rebuild into this project? How about different fuel management and bigger injectors? Stronger axles bigger brakes? the list can go on and on.

Answer 5

only used on specific types of cars each has its oun group of cars turbo can go in almost anything if you have room, supercharger usually needs a larger engine

Answer 6

turbo charged
