S7 Twin Turbo
The Saleen S7 Twin Turbo was an updated revision of the original S7. Although the initial concept for the S7 incorporated twin-turbochargers, they were not used on the production car. The twin-turbocharged version later developed in 2005 went on sale for $585,296 USD (approx. GB£295,559, c.2007/€435,203, c.2007), replacing standard S7 production.
The engine was upgraded with two Garrett turbochargers producing 5.5 psi (0.4 bar) of boost, increasing the maximum power to 750 horsepower (760 PS/559 kW) at 6300 rpm, and the maximum torque to 700 lb·ft (949 N•m) at 4800 rpm. The front and rear diffusers and the rear spoiler were also reworked to increase downforce by 60%.
Performance (Mfg Estimates)
- 0-60 mph (97 km/h): 2.8 sec
- 0-100 mph (161 km/h): 5.9 sec
- 0-200 mph (322 km/h): 27 sec
- Quarter-mile: 10.5 sec
- Top speed: 248 mph (399 km/h)
In 2006, Saleen offered an optional competition package for the S7 Twin Turbo. The package offers a 33% increase in power, to a total of an approximate 1000 horsepower (1014 PS/746 kW), as well as changes to the suspension, a revised front and rear diffuser, and an optional aerodynamic package with carbon fiber front and rear spoilers.
Currently Saleen claims a top speed of 248 mph (399 km/h) for the S7 Twin Turbo but with the 1,000 bhp (746 kW; 1,014 PS) upgrade there are rumors that the car has already topped over 260 mph (420 km/h) in testing.
