Head over to C5 for a little while, you'll find that belt slip plagues a lot of those PD guys. In my mind its too much of a PITA>

In a properly designed system, belt slip is rarely an issue, I can assure you neither application in that video is a good example of a well designed system , both the systems they compared are just about low cost. A dynamic tensioner is a must and the tensioner system must have enough travel to absorb the amount of belt stretch that occurs at max load. Any system with a manual tensioner will have problems.

It's also amazing to see how far technology has come over the last few years, they were running 12psi on a pretty well worked over 366ci engine (certainty not CARB approved) to get essentially the same power that was posted earlier with a completely stock LT1 and only 7.5psi of boost.

So far, here is not a single PD system I have seen, that doesn't fight belt slip, that is when pushing the envelope. The base systems work fine, little to no slip. the LSA conversion, whipple, yadda yadda yadda, but pully down and start increasing the boost, all of them have belt slip issues. There is a whole other market for belt slip. From what I have seen, all of it can be cured, like i said though, that issue alone is one of the major reasons I choose against a PD system.
