I just read this. Someone posted it on youtube

*IMPORTANT NOTICE*
if you purchace a grand prix with a supercarger do not i repeat do not rev it up in neutral. one of my connecting rods blew and it is quite expensive to repair it. so do not rev it in neutral or go down the highway in any other gear than overdrive. this is an important warning any please take my advice.



Btw this is where i got the text from. Damn this exhaust sounds bad.
