today at shopdap.com we talk about superchargers vs turbochargers
When you say the word supercharged or turbocharged to a regular person they
may not know why it's good, but they know it's good
the words are so synonymous with more power that they're being used on cars
that don't even have turbos, or engines. whether you're looking to buy a car that
already has one or looking to upgrade your naturally aspirated engine the
age-old question remains which one is better.
normal engine has four strokes suck squeeze bang and blow while these
sound like your late-night internet history search they actually are instructive to
tell you how an engine works. first you suck the air into the engine then the
piston comes back up and squeezes the air fuel mixture then your spark plug
ignites the mixture and bang, your piston is sent down only to return back up to
blow out they spent exhaust gases. to get more power out of your engine you need
more air and fuel to make a bigger bang superchargers and turbochargers both
operate under the same principle which is force more air in to make a bigger
bang the difference is how they accomplished it a turbocharger uses a
shaft with two spinny wheels attached to it these spinning wheels are separated
by the hot and cold side of the turbo. the hot side of the turbo is attached to
the exhaust, and the cold side of turbo is attached to the intake. the turbo uses
spent exhaust gases coming out of the engine to spin the turbine of the turbo
which allows it to force more air into the engine a supercharger in our case
uses two twisty shafts that are attached to a pulley that pulley is belt driven
and spins the two twisty shafts together forcing more air into the engine let's
talk about advantages / disadvantages. turbos are more efficient this is
because they use exhaust gases which are byproduct of the combustion process
in an engine to drive them the downside of this is that the power is not instant
due to what's known as turbo lag. turbos take time to spool this is because the
exhaust gases coming out of the engine are not going fast enough at low engine
RPMs. the advantages of the turbo or that is more efficient which also means has
more power potential but the downside is that it takes more time to make power
also they make cool noises
superchargers have instant power the second you match your foot to the floor
it's time to go.
but that immediate response comes at a cost which is efficiency since
superchargers are belt-driven they rob horsepower from the engine to allow you
to turn this pulley and while a supercharger is a giver,
it's a giver and a taker. they also make cool noises
when the comes to upgrading a naturally aspirated engine as one of these there's
a pretty clear choice turbos are used on more production vehicles are generally
easier to retrofit and have more power potential while superchargers are used
on less production vehicles are more complicated than retrofit to the vehicle
and since they're less efficient have less total power potential
this gives turbos the edge in both ease of installation cost and power potential
when it comes to buying a car with one of these it's really up to you.
the advantages over turbo over a supercharger on a production vehicle are
not going to be something that would make me select a turbo vehicle over a
supercharger vehicle or a supercharged vehicle over a turbo vehicle and because
the number of choices for supercharged cars are so limited
it would not make me shy away from a car with a supercharger but most likely
you're gonna end up with a turbo car since there aren't that many
supercharged cars on the market we have an alltrack with a 1.8 liter turbo
engine and an s4 with a 3 liter supercharged engine they both have
advantages to them but my advice would be test drive some see how you like them.
