"We first noticed the limitations of the 997 Tiptronic with our P700 (l4) PKG, which, pushed hard on certain high-octane fuels, can cause slipping in the trans," explains Tym Switzer, owner and chief engineer of Switzer Performance. "When we released our P800 kit for the 997 Turbos, which makes over eight hundred horsepower, we were forced to limit sales to manual-transmission cars."
In order to achieve their goal the team at Switzer 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.
First tests with the Tiptronic 997 Turbo concluded successfully, as the car sprinted from naught to sixty in just 2.8 seconds. This performance was achieved despite the fact the car was fitted with standard tires, air pressure and fuel.
"These cars have Bugatti performance from 0-60. We're still perfecting the calibrations, but we expect our clients will go Veyron hunting very soon, and those guys don't like to lose," Switzer added.
The company also revealed it considers building up transmissions for owners of other tuner cars as well, such as TechArt or 9ff. Switzer Performance also recommends the P800 Tiptronic as the weapon of choice for drivers who enter 0-100 or 1/8 mile dragstrip challenges.
Pricing for the transmission upgrades is set at US$7,990.
