I was thinking about supercharging my Cobra. I have looked at the Paxton, Vortech, and Procharger. I was wondering, I know that the 03 04 cobras went to a iron block because the Aluminum one couldnt handle the power. Does that mean that my block in my 01 cannot handle the power of a blower. Also what are some of the benefits of one brand over another. Do the 2003/2004 blowers fit on a 2001? Is it even worth the $3500-$5000 or will I regret it when the motor blows?
