Why does it take so much money to squeeze out minimal hp for our cars? I mean you throw an exhaust on a camaro and its 20 more whp. wtf are our cars just so beastly already that you cant do much else? and adding a supercharger creates ~50whp for a gt correct? Well why can you supercharge a stock 4.6 litre mustang and gain 150whp. And dont say you cant ive seen the tests and numbers. So what gives???
