A "properly engineered" serpentine system is tough to beat. Less power loss through belt friction, automatic tensioning, simple belt replacement after 80,000 miles or so.

Problem I see is that aftermarket accessory-drive "engineers" appear to be morons. They fail to provide adequate belt wrap, or the accessories stick up so high they look like Mickey-Mouse ears.

Judging by the "Beast" photo on the CVF web site, I'm very unimpressed with the belt wrap on the PS pump, the crank wrap looks marginal, although the A/C, alternator, and water pump look OK.

WHERE is the automatic tensioner? OEMs have proven them for the last 30+ years. (They're included in the "Wraptor" system, at $1600+)

None of the photos show how the accessories are braced from the rear. I can imagine them vibrating if CVF failed to provide adequate support in all three dimensions.

To be fair that wraptor system includes a typeII power steering pump, AC compressor and alternator. I'm seriously considering it
