My mom got a 04 Jeep GC special edition....I believe it has the powertech V-8 and i have got to say this thing has some serious bawls!(we used to have a heavy ass Landcruiser).I got one Question though,Whenever i floor it..the engine makes a cool whining/screaming noise as if it had a supercharger on it..could any one tell me wtf this noise is??
