i think the S has around 180hp
*edit
heres an epsert from an article;
The reason that the Cooper S needs the intercooler is because its diminutive 1.6-liter single overhead camshaft four has grown a supercharger. Belt-driven and amazingly compact, the roots-type blower increases horsepower from 115 to 163 and ups maximum torque from 105 pound-feet to 156. That\'s good enough, says the company, to propel the Cooper S to 62 miles per hour in just 7.4 seconds, distinctly quicker than the 9.2 seconds the company claims for the garden-variety Cooper.
