Hey guys, I'm going to look at a used Vortech H/U tomorrow morning. What are some key things i need to look for? I know to keep an eye out for shaft play, check the impeller condition and look into as much as i can for any debris inside. Anything else i should check for? Thanks!! I hope this happens! I'm going to be doing the $1500 Supercharger and Diy intercooler. This HU is only $700.
