Cadillac CTS-V - Cartek 'flip drive'

Have you guys heard of this? If so any feedback? I'm looking for ways to reduce slip on the whipple once I pulley down... The corvette guys seem to rave about this system.

I would post some pics if you haven't seen it, but it's a PITA from my phone.

8 rib pulleys man.. No slip. I would keep the drive pulley as big as possible with it goals set in mind and start out with an overdriven balancer.. See where ur at with that and pulley down accordingly
