I've always been a FAN of Centr. Blowers.

BUT belt slip is a BIG issue when pushing for much over 12psi.

Unfortunately hardly anyone makes a pulley setup for a fully optioned (A/C, PS, etc) street Mopar application that will hold anything passed 10-12psi.

There are a few Cog Drive systems out there that will hold some serious boost but built only for LA based small blocks and limited accessories

Yes, belt slippage is an issue. Ya gotta runem TIGHT!! Per Procharger, with very little or no belt tensioner free play.



They going to supply new Main Bearings and a S/C rebuild with that advice?

I have seen more than a FEW with pre-mature main bearing and S/C pulley shaft wear from tightening all the play out of the belt and pulleys.

The side load on the crank and the S/C itself become an Issue.

On a Race Car I say go for it!!!! You will have it apart and freshened at the end of the year anyways. Probably not going to hurt anything.

BUT a street rod????
