You heard it right. Vortech has teamed up with Lysholm in Sweden to develop new, positive displacement, twin-screw supercharger kits. Lysholm originally developed this blower seen in the photo above for the late-model Ford GT super car. This is a major change for the company, as it has concentrated exclusively on centrifugal compressors.
The blower's twin-screw design pulls the air in from the top of the compression screws, actually compresses it, and discharges out the bottom. “A lot of people have been asking for a supercharger that creates bottom end torque. Truck owners care more about bottom end then they do on the top end”, says Director of Sales, Gil Cormaci.

The twin-screw design means Vortech will be building intake manifolds for the VL-series. This is a whole new thing for Vortech. The parts on their vehicles display were the first made prototypes. Vortech feels that their reputation will lead people to believe in their new twin-screw blowers.
The kits will come with bypass valve, air/water cooler, and Diablosport tuner with a custom Vortech tune. These superchargers will be capable of producing over 20 PSI. The LS based kit will ship the first quarter of 2009, offered in 2.3L and 3.3L kits, with the tuner kits possibly shipping a little earlier. The GT500 direct replacement blowers will be available around the same time.
