Ohio-based engineers at Switzer Performance have released a new version of their P800 kit capable of working with the 997 Turbo's Tiptronic transmission. The transmission, normally only capable of handling up to 522 kW, was totally rebuilt and modified to handle more power.

"When we released our P800 kit for the 997 Turbos, which makes over 597 kW, we were forced to limit sales to manual-transmission cars," said company chief Tym Switzer in a press release. "This didn't satisfy the customers who wanted the kind of ultimate straight-line performance that the Tiptronic can offer, and, to be frank, it didn't satisfy us."

For the project, they added more friction surfaces to improve power delivery, improved shift speed with a new valve body, eliminated transmission slips with more clutches, and reprogrammed the entire transmission control unit software. The result is a Tiptronic 997 Turbo that sprints from 0 to 100 kph in 2.8 seconds, even when using standard air pressure, tires, and fuel.

Final calibrations are still being made to the package. The transmission itself could wind up on other Porsche tuner models as well, with Switzer believing that TechArt and 9ff may have an interest in the project.
