Not really. Belts and pulleys, SC or not, require very tight and uniform alignment. The issue is most centrifugal SCs tend to have more complex mounting and pulley systems and have the SC unit offset to the side some distance compared to most roots/screw type blowers that sit directly on the motor. With the SC offset and dangling on a mounting bracket, it is very difficult to get the pulleys and belts in perfect alignment. Alignment issues tend to cause excessive belt and pulley bearing wear.
OEMs use roots/screw type blowers for this reason as well as packaging and overall reliability. For all out power on the track, a centrifugal SC wins. For drag racing, most competitive racecars run roots/screw type blowers. IMO, if you're going to go with a centrifugal SC, you might as well go with turbo as it has WAY few moving parts and gives you massive low and midrange power plus a topend charge. Most everyone has gone turbo, both in the OEM and aftermarket.
And please don't take any of this the wrong way and I think it's great that we have more power options for these trucks. It's quite possible that this Procharger unit is super reliable.
