All blowers are the same,just have different brackets,plumbing etc. You can use a Procharger,Vortech,Powerdyne, the only thing that changes is the eficiency of the compressor,the CFM,and it RPM limit. Mine is a SN2000,with a limit of 39K RPM and max out at probably 11-13 psi.The Novi 1200 should be a pretty good unit.The Sn was a ball drive and the Novi is a gear drive,thats why they whine.Paxton had a problem with the bearings on the SN's so Craig Connely bought the right to them and re sells them now.66moneypit said:
