Re: is twin turbo really worth $44,000 ???? generally, turbos will put out more horsepower than superchargers would, but mainly at higher RPMs, people usually use superchargers because of no lag, boost is constant and that they are generally cheaper to buy. Cooler air doesn't mean more fuel can be put into a combustion chamber, it just means its more dense. Both turbos and superchargers compress air, which is how more air gets shoved into the cylinders, hence more fuel, which means more power and torque. Basically it depends on the engine, which one brings out more power. I've seen some blocks where superchargers are more efficient, and others where turbos are more efficient.
