    What do throttle bodies do? And turbos? I know roughly what turbos do.

    By the way, which has more power gain?

    Cheers

    Turbo you are likely to see more gain (as a rough non in depth answer)

    Turbos just shove air into the engine tbh (again as a crappy non in depth reply)

    TB's scare the shit out of old people when you give it some

    That is all for now

    i thought turbos sucked out the exhaust fumes from the engine?

    yeah the exhaust gasses spool up the turbo or something...
    idk,
    ask someone like Ryan.

    A turbo-charger used exhaust gas pressure to spin a high-speed turbine, which pressurises the fuel intake system, so basically chucking much more fuel at the internal situation.
    Bigger "bang" in the cylinder, more power.

    Throttle body mixes fuel with air much the same as a carb.
    Indivual throttle bodys means one for each cylinder
    Turbo & supercharger are forced induction, they pump extra air into the engine. Turbos are powered by the waste exhaust gases, superchargers are driven directly off the engine!

    except superchargers are belt driven or chain driven are they not?

    erm!

    A turbocharger is basically a high speed turbine which pressurises the air entering the engine. The names have been split now so a supercharger is powered by the engines crank - the faster the engine turns; the more boost is made (up to a point). A turbocharger uses the engines waste gases to turn the turbine.
    The turbine compresses the air and denser air contains more oxygen per cubic inch. Therefore by adding more fuel to the mix you get a bigger bang - ie more power.

    Having multiple throttlebodies does three things. It makes sure each cylinder gets the same amount of air and removes any restriction in the induction system, it also moves the throttle butterflies closer to the head which gives a better throttle response.
