thinking of putting one on my 02 with an a4. any pros & cons on a procharger? is there a better supercharger on the market than procharger? who's got the best deals on them?

 

as far as centrifugals are concerned...procharger and vortech are the best...I got a D1SC Procharger and twin highflow intercoolers from Bob at www.exoticperformanceplus.com for 3600...they will only give you the pricve over the phone because ATI has minimum prices they can print...The store is immaculate, and the the mechanics are very helpfull...they are also a shop who tunes/ repairs Ferrari's...They had the best deal, and were the most helpfull out of everyone...check out the site..its pretty cool some of the project cars they work on

 

Will make power

Eventually everyone joins the rebuild club, some sooner rather than later

 

do i need to change the gear if im going to do a superchager? i was going to install a 3.73 is has a 3.42 now and its a a4

 

Keep the 3.42s unless you plan on revving higher. I cross the traps at 6200 with my 3.73s, but rev to 6800 anyways
